Wheat and rapeseed transplanting cotton are transplanted at a late stage of transplanting, and the growth period is late. The adoption of a film-mulching transplant method can play a role of increasing temperature, keeping moisture and preventing waterlogging, and it is an effective measure for fighting against early-onset, anti-rigidity, and high yield. . The soil covered with wheat and rapeseed was ploughed and ridged in time after harvest, and the ridge was sprayed with soil to seal the treatment agent. Combine 0.25 to 4000 kg of organic manure per acre, 40 to 50 kg of compound fertilizer, and 1 to 2 kg of boron. When transplanting rape seedlings, the transplanting period must not be later than May 25. The wheat cocoon cannot be later than May 30. Seedling age should not be too large, seedlings have 2 to 3 true leaves when transplanted. Seeding early and seedling-bearing seedbeds should be promptly controlled and transplanted. Seedlings should be planted separately. When transplanting, 2 cm from the ground is placed on the ground, and half of the pond soil is buried after pouring, and water is poured. After the water is infiltrated, the carcass is buried flat. The transplanting density depends on the soil strength, with 1400-1800 plants per acre. After transplanting, field management such as cultivating and weeding should be strengthened. The fertilizer and water management clean up the “three ditch†in a timely manner, so that the ditch and ditch can communicate with each other and be discharged freely. After easing the seedlings, the seedlings shall be applied in a timely manner, and 3 to 5 kg of urea per mu. After budding in mid-late June, there are 4 fruit branches when Shi Lei Fei, 10 kg of urea per mu, 10 kg of potassium chloride. Into the flower and boll period, when the lower part of the seated one or two bells, the flowers and bolls were reused, and 15 kg of urea and 15 kg of potassium chloride were used per acre. One week after the topping (August 10-15), top fertilizer was applied and 5 to 10 kg of urea was used per acre. Take a deep ditch to apply fertilizer. After the end of August, foliar fertilizers were sprayed according to the growing conditions of the plants. Nitrogen fertilizer and potash fertilizers were mainly used for spraying weakly, and phosphorus and potash fertilizers were mainly used for spraying. Pruning and controlling the first pruning should not be premature, in order to promote vegetative growth and root growth and development, generally when there are 2 to 3 fruit branches, the total removal of the branches under the fruit branches, do not remove the big leaves. The future pruning is performed in conventional cotton. From the start of budding period, when the cotton plant had 4 fruit branches, 0.5 g of water and 25-30 kg of water per acre were sprayed on the top of the plants. The second chemical control in the early flowering period, according to the plant growth rate of 1 to 2 grams per acre pure pharmaceutical. Into the bolls, the fourth fruit branch see the bell, with a methothene 3 to 4 grams per acre. After topping, use 5 to 6 grams of pure methothene per acre. The amount of methylphenidate should be adjusted according to the weather, seedling conditions and soil strength.
