Last Updated: 2024/11/22, Cotton plastic film mulching has the characteristics of stable yield, high yield, high quality and economic efficiency, the yield per mu is up to 100W, the main cultivation measures are as follows: 1. Fine soil preparation, the first deep soil layer, fertilizer and water conservation of the land, made into a width of 60-70 cm, 8-10 cm high bed, with wood rolling repeatedly suppressed twice. two。 Seed treatment should be in the sun, strict seed selection, sulfuric acid depilation, germination test, and cold water before sowing. 3. Sowing at the right time, the best sowing time is 7500-850 seedlings per mu on April 25th-30th, covered with film in the middle of the edge.

Cotton plastic film mulching has the characteristics of stable yield, high yield, high quality and the same economic effect. the yield per mu is up to 100W. The main cultivation measures are as follows:

1. Fine soil preparation, the first deep soil layer, fertilizer and water conservation of the land, made into a width of 60-70 cm, 8-10 cm high bed, with wood rolling repeatedly suppressed twice.

two。 Seed treatment should be in the sun, strict seed selection, sulfuric acid depilation, germination test, and cold water before sowing.

3. Sowing at the right time, the best sowing time is 7500-850 seedlings per mu from April 25th to 30th, covered with film in the middle of the edge to avoid water loss.

4. Apply 3000-4000 kg of farm manure, 50-80 kg of ammonium sulfate, 15 kg of phosphorus and 5-10 kg of potash fertilizer per mu of scientific fertilization. the main application method is base fertilizer, and the rest of nitrogen fertilizer is less than 10 cm. Excessive application of chemical fertilizer at one time, resulting in the phenomenon of rotting sprouts.

5. Strengthen the management of pyrethroids pesticides to water, use 3000-5000 times liquid to control cotton bollworm and cotton aphid at the same time; help cotton pruning, ─ 10 on July 5 hit the top, leaving 6.5-70000 fruit branches per mu whichever is whichever is higher, and 2-3 fruit knots are left on fruit branches on July 15; on July 5, ─ 10 is sprayed; ethephon should be sprayed in time to accelerate ripening when less than half of the work is done on September 20.
