The general reason is that the number of workers is high, the investment is high and the market risk is high.
However, after interviewed by the chief stationmaster of Sheyang county economic development station in Zhuang Yuan county of cotton planting in China, the reporter found that the reasons should also include the attenuation of favorable conditions of cotton seed in recent years, which caused frequent occurrence of natural disasters in cotton growing season and seriously affected the increase of cotton yield per unit area.
This problem needs to be paid enough attention.
Sheyang is one of the earliest counties to introduce insect resistant hybrid cotton, because insect resistant hybrid cotton has the advantages of saving labor, saving money, increasing production and quality, compared with conventional cotton, and has a high penetration rate of 95% across the county.
But in recent two or three years, insect resistant hybrid cotton has a single pest resistance and a drop in resistance to disease.
As far as insect resistance is concerned, insect resistant cotton appears to be more and more difficult to cure when it is used to prevent and control Helicoverpa armigera.
Although the wilt and Verticillium Wilt of the pgenic cotton have been reduced since the introduction of pgenic hybrid cotton, the quality of some hybrid cotton has been decreasing along with the confusion of cotton seed market in recent years.
Ji station worried about the introduction, now cotton area
Seed cotton
There are two kinds of people who form strong contrasts, one is cotton planting experts, and the two is old granny.
The old cotton farmers or those who failed to carry out scientific multi cropping farming and cotton seedling pplanting density were too sparse; or in order to reduce the cost of cotton planting, they were obviously insufficient in fertilizer and labor input, resulting in a decline in seed cotton yield.
