All localities should guide farmers to do the work of soil moisture conservation and soil moisture conservation, so as to realize the whole sowing of cotton.

Irrigation should be done on the 15 day before planting, so as to increase soil temperature.

cotton field

Irrigation is 60~70 cubic meters.

After watering, the soil should be raked and covered in time, and the soil should be 5 centimeters or so.

In dry upland cotton fields, sowing seeds and soil before planting and sowing the soil for soil moisture will help to sow the soil and sow seeds.

Fine soil preparation, applying base fertilizer and selecting superior seeds.

Before sowing, we should do a good job in the flat, ploughing, raking and rolling of the cotton fields to achieve the virtual reality, without rough and down, and generally combine the farmhouse fertilizer for about 15 centimeters.

The amount of fertilizer required is determined according to soil fertility and production targets.

The base fertilizer mainly supplies three kinds of nutrient elements, such as nitrogen, phosphorus and potassium fertilizer. In addition, organic fertilizer such as barnyard manure and rotten straw should also be added.

At the same time, in line with the principles of strong adaptability, good quality of seeds and reliable source, we choose good varieties.
