Use 160 cm area, sow 4 rows of wheat, leave 100 cm gap to plant overwintering vegetables (small canola or garlic sprouts), and plant 2 rows of mulch cotton after harvest in mid-April of next year. Intercropping cotton grows slowly due to shading of wheat and late cotton bolls. Because of the low temperature and low bolling speed, the budding period is rapidly growing by the rain and heat, and the budding bells are shed more and less in front of the prunes. The use of full cultivation and management to promote the main, promote control and integration, can achieve Baole bell, promoting the purpose of precocious maturity. (1) Covering the film to promote the growth process After the wintering vegetables are harvested, 3 m3 of organic fertilizer is applied per acre, 40 kg of nitrogen fertilizer, 13 kg of phosphate fertilizer, 8 kg of potassium fertilizer, and then artificially deep-turned by 20 cm, and the tape is covered by 80 cm. Membrane, rainy season in the tape on the 5 cm from the edge of the film sowing a row of cotton (medium maturing varieties), spacing 70 cm, wheat after the receipt of a size of 90-70 cm line; diagonal hole, hole 25 cm, each Mu maintains 3,300 points. Use geothermal effects to promote the growth process. (B) timely development of pest control and development process using black light, high-pressure mercury lamp moth extermination, spraying Bt biocides, chemical pesticides and other methods to control pests, to control the generation of cotton bollworm seedlings, prevention and control of the second generation of top protection, prevention and control of three generations Bao Lei, the purpose of preventing and protecting the four generations of bolls, normalized the growth and development of cotton plants and increased the pre-frost flower rate. (III) Whole-process control to promote fertility and robustness In early June, 0.5 kg per acre was used to spray 25 kg of water to control the plant height of 25 kg per mu; in the beginning of July, 1 kg of melatonin and 40 kg of water were sprayed to spray the tip and strain of fruit. Top control plant type; topping the heart (July 23) with a shrinkage gel 1.5 grams of water 50 kg spray the entire plant against axillary buds, reducing cotton plant self-nutrient consumption, improve light energy utilization; mid-August and In the second half of the year, spray 1% urea solution and 0.3% potassium dihydrogen phosphate solution 50kg to ensure that the upper functional leaves are not damaged. (D) artificial regulation and promotion of cotton bolls early precocity on July 20 to hit the top heart, on August 10 hit the side of the heart, leaving only fruit branches open two flower buds after the triangular fruit bud; in early September to remove all the buds of unopened yellow; early October The use of 40% ethephon 150--200g per mu water-spraying cotton to promote the transfer of cotton boll, to ensure that in late October Tengjiao planted wheat.
