First, the stable growth of cotton fields should not be blindly expanded.
In recent years, the area of ​​cotton fields in China has changed greatly, and farmers have suffered a lot of losses. The lesson is very profound. First, the price fluctuations are affected by the international cotton market; Second, domestic cotton prices are unstable, and farmers have difficulty in grasping; Third, the cotton production area. The prediction of production is very inconsistent and the reliability of information is poor. It is difficult for farmers to determine how much cotton to plant. In view of past lessons, the area of ​​cotton fields this year should only recover, with an increase of 10%, and no more than 15%. Of course, localities should adapt to local conditions.
Second, change the bed to improve soil fertility, improve water facilities.
First, according to cotton varieties and cotton field fertility reform, to determine the cotton field ditch, the general width of the hybrid cotton seedlings is appropriate to 2 meters wide, two kinds of cotton; two to change the long box to a short box, every 50 meters long to open a Waist groove; Third, under the premise of the reform, the new cotton fields are completely ploughed, so that the winter sun spring, not only loose the soil, but also kill some of the overwintering pests, but also to kill part of the weeds. In combination with land leveling, to overcome the uneven status quo; Fourth, we must increase the application of organic fertilizer on soil with poor soil quality, especially bio-organic fertilizer, phosphorus and potassium in the absence of soil to prepare early phosphorus and potassium fertilizer; Fifth, improve cotton field water system Facilities, so that the speed of large hydropower, there is water drought, rainfall can filter.
Third, do a good job of sub-training to improve the level of cotton.
According to the agricultural activities of cotton production, the technical guidance to the cotton-growing farmers should be strengthened. First, they should be guided to select the targeted varieties, and the planting of insect-resistant cotton and hybrid insect-resistant cotton should be encouraged. Secondly, it is necessary to emphasize that improved varieties must be planted with good methods to obtain high yields; Third, according to the soil testing formula, prepare for the lack of fertilizer; Fourth, we must pay attention to climate change, as early as the preparation for the prevention and treatment of various types of pests.
