Problems solved by technology

[0003] According to the existing problems, the present invention provides a method for growing cotton by drip irrigation with warm water. According to the moisture, heat and air in the soil required for cottonseed germination, the method utilizes warm water in the form of a drip irrigation belt to meet the needs of cottonseed germination. Water and heat requirements, thus replacing the plastic film covering seedlings, overcoming the problem of continuous accumulation of film residues in the cultivation layer

Embodiment

[0011] At the Aksu Field Experiment Station in Xinjiang, after the soil was thawed in early March, spring irrigation was performed in the deep water layer of 40 cm. In early and mid-April, rakes were plowed, ditches were sown, and cotton seeds were sown on the bottom of the ditch. Drip irrigation belts are laid in the bottom of the ditch, and the row spacing between sowing cotton seeds and laying drip irrigation belts is crossed;

[0012] One end of the drip irrigation belt is set in the pump room in the field, and the water is heated in the pump room. The water temperature is 20-30°C, and the drip irrigation is carried out through the drip irrigation belt to increase the temperature and moisture of the soil. It takes about 20 days from sowing to emergence. Warm water drip irrigation, drip irrigation once every 3-5 days, according to the soil moisture, can be flexibly controlled. After cotton emerges, warm water will continue to drip irrigation for 10 days. When the surface tem...

Abstract

The invention relates to a method for sowing cotton by warm water drop irrigation. Cottonseeds are sowed at the ditch bottom; drop irrigation belts are paved inside the ditch bottom which is adjacent with the cottonseeds. The drop irrigation is carried out by the warm water so as to satisfy the requirements of water and heat in the soil required by cottonseed germination, thereby replacing plastic films to cover seedlings and overcoming the problem of residual film cumulation inside plow layers.

Description

technical field [0001] The invention relates to a method for growing cotton by drip irrigation with warm water Background technique [0002] Cotton seedlings were usually raised with soil surface warming agents in the past. Due to serious organic pollution, transparent plastic film seedlings have been used for seedling cultivation since the 1980s. Since the film residues will not disappear by themselves, the film residues in the cultivation layer will accumulate. The more it is, the air permeability and water permeability of the soil will be seriously affected, and the cultivation and plant growth will be affected. Due to the high price of the developed degradable film, it is difficult to popularize and use it in remote and poor areas. In order to overcome the problem of continued accumulation of film residues in the plow layer and to increase the germination rate of cottonseed, it is necessary to increase soil temperature and moisture. [0003] According to the existing p...
