Rape-vegetable-capsicum-cotton-cotton

In order to stabilize the development of cotton production and overcome the unsteady status of single cotton planting, in 1994, Wannian County in Jiangxi Province interplanted "harvest" (greens, lettuces, etc.) with rape as a "summer vegetable" (chili, Four crops, beans, etc.) were used to conduct trials and researches in the four-year hybrid cropping pattern. After four years of trials and production demonstrations, a complete set of cultivation techniques was concluded. At present, the county has an area of ​​1500hm2, with an average hm2 output value of 40,000 yuan, which is more than double the efficiency of the conventional oil-cooked two-matured crop, especially the rapeseed-vegetable-pepper-cotton intercropping pattern, which can produce 1500kg per hm2 of rapeseed. 22,000 kg of vegetables, 22,000 kg of peppers, 1800 kg of lint, and an output value of up to 60,000 yuan or more. It is an efficient and multiple cropping pattern that is easy to operate and widely accepted by farmers. It is suitable for promotion in the hilly cotton regions of the Yangtze River Basin. First, the fine soil preparation, a reasonable layout of the fine soil preparation after the autumn harvest, open the ditch to do 畦, 畦 surface width 1.4m, sulcus width 0.3m, north and south direction, every 667m2 shishi heterozygous 2000kg and ternary compound fertilizer 25kg. A row of rapeseed on both sides of the plant, plant spacing 15cm, the middle of the second row of vegetables, plant spacing 25cm, vegetables after the end of the second row of pepper planting, plant spacing 35cm, after the oil harvest after transplanting cotton. Second, the selection of improved varieties, seedlings transplanting rapeseed selection Zhongyou 821, green Shanghai green selection, pepper selection Xiangyan No. 1, No. 4 or Jiujie Jilin, cotton selection of No. 3 cotton. Rape sowed in early October, transplanted in Zhongdian in November, planted in late October in October, transplanted with rape at the same time, pepper in Zhongdian in November, sowing seedlings in the hotbed, planting in mid-January, transplanting in mid-March, arch cover Cotton is sown in early April and transplanted in early May. Third, to strengthen the management of the field before the pods: rape, vegetables timely watering nursery after transplanting, Shimiao Miao Fei, ensure rape seedlings overwintering and vegetables and morning market, after the close of vegetables, rape timely fertilization soil, to be basically thanked After flowering, it can be squeezed into the ditch to create ventilation and light conditions for the peppers. Pepper: When transplanting, every 667m2 of Sanyuan compound fertilizer and cake fertilizer each have 20kg of paddy bottom, pour good live water, clear film on sunny day, raise temperature steadily and remove film, timely cultivator Songshi fertilization, cut off the lower no effect branch, enter During the result period, topdressing 10 kg of urea and potassium fertilizer respectively, finished in early July. Cotton: Apply the base fertilizer during transplanting, apply nitrogen fertilizer at the bud stage, use 25ml of 25% auxiliaries and 5ml of water per 667m2 in the 8-leaf stage, and pay attention to the damage of the cotton locust and diamond drill before harvesting the peppers. , Can generally use snacks or spray the top of the plant method of drug control, after the close of the pepper, the old trench filled with broken, fill every 667m2 with cake fertilizer 50kg, urea 10kg, potassium 20kg, phosphate fertilizer 25kg, 0.5kg boron and zinc Applied into the ditch, other management with the routine.
