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, which has caused many traumas to farmers. The lesson is very profound. First, the impact of the international cotton market is volatile. Second, domestic cotton prices are out of control, and it is difficult for farmers to grasp; third, cotton production area, The output forecasting caliber is inconsistent and the reliability of the 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 should only be expected to recover, with an increase of 10%, and a maximum of 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, what fertilizers are lacking are prepared for the shortage of fertilizers earlier; Fourth, we must pay attention to climate change and prepare for the prevention and control of various pests and diseases as early as possible.
