Think twice before you expand cotton planting

First, cotton fields are growing steadily and should not be expanded blindly.

In recent years, the area of cotton fields in China has changed greatly, and farmers have lost a lot, and the lessons are very profound: first, prices fluctuate greatly under the influence of the international cotton market; second, domestic cotton prices are unstable and it is difficult for farmers to grasp; third, the caliber of cotton production area and yield forecast is very inconsistent, and the reliability of information is poor, so it is difficult for farmers to determine how much cotton to plant. In view of the lessons learned in the past, the cotton field area should only be restored this year, with an increase of 10% and no more than 15% at most. Of course, all localities should take measures in accordance with local conditions.

Second, improve the compartment, improve the soil and increase fertilizer, and improve the facilities of the water system.

First, it is necessary to reform the planting mode according to cotton varieties and the fertility of cotton fields, and it is appropriate to plant hybrid cotton boxes with a width of 2 meters and grow two rows of cotton; second, long boxes should be changed into short boxes, with a waist ditch every 50 meters long; and third, under the premise of changing the box, comprehensively ploughing new cotton fields to make them dry in winter and spring, not only loosening the soil, but also killing some overwintering diseases and insects, but also killing some weeds. And combined with the leveling of the land to overcome the uneven status quo; fourth, to increase the application of organic fertilizer to the soil with poor fertility, especially bio-organic compound fertilizer, and to prepare early phosphorus and potassium fertilizer for the soil lacking phosphorus and potassium; fifth, to improve the water system facilities in cotton fields, so that large water can be discharged quickly, water can resist drought, and rainfall can filter quickly.

Third, do a good job in stage-by-stage training to improve the level of cotton planting.

According to the agricultural activities of cotton production, strengthen the technical guidance to cotton farmers: first, guide them to select targeted varieties and advocate the cultivation of insect-resistant cotton and hybrid insect-resistant cotton; second, emphasize that improved varieties must be planted with good methods in order to achieve high yield; third, according to soil testing formula, prepare the lack of fertilizer; fourth, pay attention to climate change and make early preparations for the prevention and control of all kinds of diseases and insect pests.
