New points of potted chrysanthemum conservation

Chrysanthemum perennial sub-shrubs, because of their wide variety, so the leaf shape, flower type, flower color varies greatly. For cultivation of chrysanthemum flower is big, color beauty, color green, medium height, body symmetry, we must grasp the following technical measures:

First, the chrysanthemum hi fertilizer, if fertilizer improperly can lead to excessive growth. Therefore, should basal P and K based. Fertilizer is not applied too early, if small, thin leaves, leaf yellowing, 0.1% for multiple spraying urea water to turn green stops. Prior to flowering after the beginning of autumn, fertilizer and water should be sufficient to gradually increase its concentration and increased attention to applied P and K should enable the color is, long flowering period, timely spraying of a new lipid membrane, the limited ingredients greatly improve the rate of pesticide.

Campsis clever management of growth

Cultivation and management: transplant in spring and autumn for the plant usually takes places with the soil, planting should choose Peak lee sunny place, germinating in early spring before planting. Established before the first stent colonization, so that branches climbing on it. Cave planting shovel compost facilities l ~ 2 for basal, pouring enough water after transplanting, spraying the new fat membrane, which can not effectively prevent the evaporation of ground moisture, seedling transpiration of water is not the body, cut off from pests and diseases, reduce Huanmiao period.

Impatiens disease prevention and control measures

Impatiens disease stems major damage. Grease-like roots at the beginning of the dark green strip show plaques and rapidly expanded into a dark brown irregular, severe stems, leaves all the black, the plant will soon fall off, root neck, depression, death caused by plant lodging. Control measures are as follows:

1, the reduction of primary infection source. Improve garden health, land use next year, and plowing the land several times in the summer, the full force of the sun and reduce the strain of life, sunlight can make the spore germination of resting eggs, which lost infectivity. Complete removal of the sick deformed autumn can reduce disease.

How to manage after the winter flowers

Into the winter, the flowers, the management of change in the weather to be timely and based on moving, pay attention to temperature, moisture, light, foliage pruning and other factors, and the timely adjustment of treatment, is conducive to flower growing well.

1. at this stage flowers most important part of conservation management is the control of water and fertilizer, from early October should begin to reduce amount of water to avoid rot of winter water and more. Second, to increase the nutritional content of flowers, was applied to the flowers of nitrogen-based fertilizer to, not only can make flowers grow lush robust, but also improve the ability to flower after the winter's cold. At this point chrysanthemum, bloom, Magnolia, bud schlumbergera other is, and Rose, both of Clivia and other longer branches, in turn bud, should be noted that phosphorus-based fertilizers additional 2 to 3 times, and promote flower bud Flowering.

2. burglary time can be dealt with separately according to different varieties of flowers. Hibiscus, poinsettia, begonia, cyclamen, jasmine, Coleus, Monstera and other warm-flowers during the day should be moved to the indoor air temperature 10 ℃; Chlorophytum, asparagus, Pleione, tulip wood, rubber trees, etc. , 5 ℃ in daytime temperatures into the room. To ensure the vast majority of flowers in the frost before the burglary.

3. always winter pruning is an important part of flower management. Most of flowers such as jasmine, crape myrtle, pomegranate, etc., can be trimmed at this stage of shaping the plant nutrients in the winter to reduce consumption, encourage more flowering potted plant next year. Pruning to remove diseased branches, twigs, closely spaced branches, leggy branches, lay a good foundation for the potted winter. Callus should be promptly applied anti-corrosion film to prevent water evaporation and nutrient consumption. Second, the new fat film spraying antifreeze to heat. (Qiu Feng)

Pesticides: domestic and foreign enterprises how to profit

Recent major domestic and foreign pesticide manufacturers have announced results for 1-9 months, from domestic enterprises and foreign pesticide listed multinational pesticide performance comparison is clear that the performance of domestic and foreign enterprises 冰火两重天.

Comparison of the data clearly shows that the major pesticide companies at home and abroad the first three quarters of this year 冰火两重天 operating results, and use of pesticides in rice this year, most of the market share of foreign patent varieties, such as pesticides Kang W, Foggo, ridge songs Rice Teng; herbicides daughter, Joy Rice, rice Jie, Han and good autumn. Multinational companies derive a lot of profit. Domestic capacity for independent innovation is weak, the bulk of excess capacity pesticide products, the domestic impact of extreme weather, export tax rebates and energy savings may be the cause of such a huge contrast to the above factors, but by a number of pesticides or industrial Park, knowledge of business and situation analysis Several factors should be cause for concern and thinking.

First, the scale of domestic pesticide companies is generally small, well-known pesticides and the future lies in innovation competition, but smaller companies can not share and bear the high development costs, so "second Five-Year" period, the government and related departments should speed up the organization of pesticides structural adjustment and more advantage of the pesticide business combination, through the joint venture, merger, reorganization, etc. formation of large pesticide companies to compete with foreign multinationals.

Second, brand awareness and resource protection, associations, agricultural extension, local government and enterprises should strengthen communication, increase the quality of domestic brands recommended pesticides and publicity, production enterprises should attach great importance to product quality control and development of new products, and expansion of traditional products are not blind. From a strategic point of the relevant state departments to continue to strengthen the production of pesticides needed to protect the efforts of non-renewable resources, such as phosphorus and fluorite resources, integration of resources, reduction of export quotas to limit destructive mining, the pesticide industry in China to provide resources and support sustainable development .

Third, attention and regulate pesticide production and development of infrastructure in recent years due to rapid internal pull, basic chemical raw materials, market demand, economic efficiency is better, so a lot of resources for the expansion of basic chemical products. Many provinces and regions, "Eleventh Five-Year," the fine rate and the "fifth" period compared to significant decline in fine chemical products as pesticides because the relatively small size of local GDP is not driven, so the development environment and be encouraged level is not optimistic. Pesticides affect 1.3 billion people eat as products, not only from the relevant departments of the development of oral attention, but more should be funding, taxation, environmental and other aspects to give real support, both from policy to regulate the industry behavior.

Monsanto Yi Bowen: actively promoting the planting of biotech crops

NetEase Financial News in July 2010, Monsanto Yi Bowen, president of North Asia, will be guest of NetEase living room. They are the largest seed companies, ninety percent of the world of genetically modified crop seeds come from it or its authorized, transgenic technology and the application of biotechnology, seed industry products, the company's biggest bright spot, also become a The most controversial of the company.

The introduction of genetically modified cotton seeds in India large-scale farmer suicides brewing

The Beijing News reported on June 20 since 1997 nearly 20 million Indian farmers committed suicide, in which a large proportion of cotton farmers! The introduction of transgenic cotton, seed prices, farmers loans, crop failure, unable to pay, the bank no longer loans, loan shark, farmers, unable to pay, go bankrupt, the last suicide --- the sad chain of Indian farmers committed suicide to show the general process. Local people blamed the U.S. sent genetically modified seed companies, globalization has brought to India an unexpected change in agriculture. However, if the protection of sound, then, only a genetically modified cotton seeds to be able to make 20 million or more Indian farmers collapse?

5 at the end of the day in 2009, the Indian state of Maharashtra region northeast of Ouidah woman, a young mango tree farmers Guo card is wiped tears of sorrow. Five days ago, his father hanged himself in this tree. A white turban and a pair of dilapidated sandals still in the trees, but their owners because of inability to pay 850 dollars in debt choice Sashourenhuan.

According to the National Crime Record Office statistics, from 1997 to date, nearly 200,000 Indian farmers committed suicide, in which a large proportion of cotton farmers.

Sudden increase in number of suicides

"Ten years ago, farmers can sustain life." Guo said cards, and many local farmers, he will blame his father's death the impact of globalization and genetically modified cotton in large-scale cultivation.

Ti Wali from Maharashtra was an engineer, and now his full-time job is to record the farmer suicides, wake-up state of the whole society concerns about the survival of farmers.

In his office, from floor to ceiling were painted over the chart, above records from 2001 to 2009 Vidal woman farmer suicides all areas. "In 2001, 52 suicide." Tiwa Li reading aloud, and the following years, this figure was almost straight up, "2002 104 2003 148 2004 447 from 2005, 445, 2006 1448 from 2007 1246 from 2008 from 1267. "when the average daily maximum of three farmers have committed suicide.

As farmers suicide rate is too high, the Government of India devoted to the statistics. The most common methods of suicide are hanging and poison, the most frequent suicide region is the cotton-growing belt in central India.

Tiwa Li believes that the United States beyond our shores, Missouri, the world's largest seed company Monsanto (Monsanto) is the main cause of these tragedies. Transgenic cotton seed trade has not only changed the agricultural production, but also to the Indian community is the great unexpected changes.

Lure lucrative high seed

The past, cotton seeds cotton farmers in India spending one of the smallest expenses.

Although production point of view, less than Indian cotton seed of transgenic cotton from the United States, but it can adapt to the unique climate of India --- every summer monsoon rainy season and subsequent long-term drought.

And Monsanto has changed all that. The last century, the company developed a genetically modified cotton, it can kill the bollworm larvae to produce a special protein toxins, making the cotton against their natural enemies can withstand.

2002, entitled "Paul Bell Cotton" genetically modified cotton seeds in India market. Per acre of farmland for cultivation of cotton for sale at Paul Bell 1400 rupees, about 35 U.S. dollars. Despite the intervention of the government that the company will lower prices by half, but only a few hundred dollars for the annual income of cotton farmers is still a small fortune in terms of overhead.

Transgenic cotton was originally brought considerable economic benefits, India's cotton production has doubled. In 2005, this cotton cultivation to reduce the use of pesticides 42%, planting transgenic cotton revenue per acre higher than non-transgenic cotton, $ 373. But did not last long, all the disadvantages also will appear. Small-scale farming for farmers in India, GM cotton is that they bring unexpected variables.

GM "acclimatized"

And the local Indian cotton, transgenic cotton needs more water to irrigation.

This large-scale cultivation of cotton farmers in the United States is not a problem, as long as the irrigation system can ensure complete harvest. However, the situation is different in India, All India 90 million farmers, 60% have less than 2.5 acres of farmland. So they planted transgenic cotton, the more "dependent on the weather," largely depends on cotton crop year rainfall.

Indian Central Cotton Research Institute study found that after 5 years, has a small amount of resistance to transgenic Bt cotton resistance to the toxin produced. Scientists predict that, after 10 generations of cotton cultivation, will generally be resistant to bollworm.

Produced in response to pest resistance, common practice is "bio-shelter strategy." In the United States, the provisions of transgenic cotton in the area must have 20% of the normal non-transgenic cotton planting as a refuge for cotton bollworm, but only for large farm operations of GM crops. For small-scale cotton cultivation in India is difficult to promote Moreover, the two countries have different types of cotton bollworm.

Debt to borrow money to buy seeds

The introduction of transgenic cotton in India a few years later, the seed store to buy cotton seeds are labeled as genetically modified, resulting in greatly increased the cost of cotton farmers, but there was a mix of a lot of fake and shoddy products.

Because the transgenic cotton seeds high prices, some unscrupulous businesses in India will be non-genetically modified cotton seeds or pure labeled as genetically modified seeds sold in the market. Survey, non-formal brand on the market, only 26% of the first generation of GM cotton seed is genetically pure, 46% are mixed with non-transgenic cotton. They are treated as true if the GM cotton will bring painful economic losses.

Before the advent of transgenic cotton, the seeds of only a small fraction of the cost, if the current year's cotton harvest, farmers sharp drop in income in the second year of life will suffer some, but not a bankrupt.

But now, in order to buy seeds, most farmers National Bank loans to India. But if buy fake seeds or poor harvests, farmers unable to repay in the same year, the bank will refuse to provide loans again, this time farmers have to look for private banks loans. In addition, farmers who own no land can not apply for a loan from the bank, can only take the risk of higher loan-sharking way. In some places, usurious interest rates of up to 100%. And again, if the second harvest of cotton, or even just as expected harvest, the farmers will enter the vicious cycle of debt.

A farmer committed suicide by taking poison insolvency relatives said: "We heard that there will be a good harvest of genetically modified cotton, so everyone look for bank loans. May be the result not the case."

Survival of the underlying worrying farmers


Woman in the Maharashtra region Vader, his father committed suicide a few days later, Guo cards and brothers know his father who had been owed debt. Father from the first bank loan, then find a private loan shark. Son know his father on hand tight, but they did not expect the debt will father a corner.

Guo father's death card will be attributed to the high cost of seeds purchased. "If he does not loans to buy seeds, all of which will not happen." Father is the breadwinner of the family, but lost his father the day, the whole family have to rely on cotton for a living.

Indian scholars have pointed out that the GM cotton farmers are a large number of suicides caused by the incentive, it is not the only factor. Toward urbanization in the Indian context of the government and society failed to give adequate living conditions of the farmers concerned. And because the city makes a number of economic downturn experienced people to the countryside without agricultural farming. When the deterioration of economic conditions of farmers, because of security mechanism is not complete, committed suicide as their only choice.
