After years of development, cotton intercropping has become more diverse. The author summarizes and explores the experience of cotton, soybean and pea interplanting among some cotton farmers in this county in recent years. First, apply base fertilizer, fine soil preparation. Before the planting of soybeans, deep plowing and intensive cultivation of the cotton fields should be done so as to make the ground soil fine, combined with 1,000 kilograms of farmland fertilizer per 667 square meters (1 acre), 50 mg of superphosphate or calcium magnesium phosphate, and 50 kg of ammonium bicarbonate as the base fertilizer. . Then ditch the 167 cm ditch to make the ditch, the ditch width 33 cm, and dig a good three ditch. Second, transplanting cotton seedlings. Cotton seedlings were planted at the end of March and early April, transplanted to Daejeon at the end of April and early May, and the width of the line was controlled at more than 100 cm. The cotton spacing is 40 centimeters, ensuring cotton density of 2,000 plants per 667 square meters. III. Soybean Intercropping Technology Essentials 1. Select good seeds and sow at the right time. Soybeans should use early-maturing, high-yield, and high-quality varieties, of which the best benefit is the use of early-early soy beans, and the symbiosis with cotton is relatively short. At the beginning of April, two rows of soybeans were planted in the middle of the pot, with a spacing of 25 cm and a 10-cm spacing between the holes. Each hole was sown with 4-5 grains and leaves with two seedlings. Rhizobium should be inoculated before sowing in order to increase the number of nodules and improve nitrogen fixation. After emergence and time seedlings, at the same time do a good job to fill the gaps. Weeding and weeding should be early and diligent, and we should practice cultivating three times before weeding. From the flowering stage to the flowering stage, the paclobutrazol solution with a concentration of 210-6 was uniformly sprayed on the opposite sides of the leaves, which inhibited vegetative growth, promoted reproductive growth, and increased the rate of single-seeded pods and seed setting rate. 3, timely and clever fertilizer. In the seedling stage, depending on the amount of seedlings topdressing urea, promote early-onset seedlings. The flowering period should be topdressed with 2-5 kg ​​of urea and 20 kg of phosphorus and potassium compound fertilizer. The difference in growth potential should be applied more, and the growing and lush should grow up with little or no urea. During the grain stage, foliar application of potassium dihydrogen phosphate, ammonium molybdate, and other trace fertilizers are performed twice. Each time, 667 square meters of potassium dihydrogen phosphate (50 g), ammonium molybdate (15 g) and borax (50 g) are used. Dissolve 25 kg of water and apply evenly on the stems and leaves of the plants. 4. Pest control. To prevent rat damage after sowing and before emergence, rats should be administered at the end of the field. Soybean diseases mainly include viral diseases, rust, powdery mildew, and downy mildew. Virus disease is mainly transmitted by locusts. It is necessary to prevent and control maggots on the basis of the virus; rust and powdery mildew can be controlled by triadimefon or zeocin; downy mildew can be controlled by chlorothalonil. Soybean pests mainly include aphids, leaf miners, red spiders, Spodoptera litura, and soybean meal. Aphids, leaf miners and spider mites can be controlled by low-toxic and low-residue pesticides such as pyrethroids and daphthones; Spodoptera litura and soybean meal can be controlled by BT biocides and enemies. Four, peas nesting technology essentials 1. Select good seeds and sow at the right time. Peas should use precocious medium peas 4th, medium peas 6, and other good quality varieties to facilitate fresh oysters in the morning market. In late November, two lines were planted at each point along the cotton plant, with a 20-centimeter hole and 2-3 seeds per hole. Combine sowing with calcium, magnesium, phosphorus 100 kg per 667 square meters. The bottom water should be poured before sowing to keep the soil moist. 3, pest control. To prevent rat damage after sowing and before emergence, rats should be administered at the end of the field. Pea diseases include downy mildew, powdery mildew, and brown spot, which can be controlled by carbendazim and thiophanate. Insect pests mainly include aphids, leafminers, etc. They can be controlled by low toxicity and low residue pesticides such as pyrethroids.

2, timely picking and spraying paclobutrazol. Topping can promote robust growth of stems and leaves and prevent lodging. Generally, it is good to pick the best weather during the flowering season. Plants with high fertility and prosperous growth should be picked early and re-extracted. Plants with lower fertility and weaker growth should be lightly picked or not picked. After topping, use carbendazim spray to prevent diseases.
2, field management. After emergence, the supply of water and fertilizer should be controlled so that the seedlings are not susceptible to freezing over winter. After the spring, combined with the middle ploughing to raise the seedlings, the top dressing is applied 1-2 times, and the best results are obtained with the application of acupuncture points. Each application of three-component fertilizer is 5-10 kg.
