First, timely sowing and sowing. Achieving complete seedling sowing is the key to the high yield of summer soybeans. To promote the sowing of soybean cultivators for no-tillage sowing can be carried out immediately after the wheat harvest. Rotary ploughing, fertilizing, sowing, and suppressing all-in-one machines can be used to increase the quality of sowing. Wherever conditions permit, soybean no-tillage and mulching sowing machine can also be used for sowing. In the event of drought, watering and sowing can be used. Based on species characteristics and soil fertility levels, combined with the control technology, a reasonable increase in density to increase soybean yield. Generally, about 6 kilograms of seed are planted in Mu, and the planting distance is about 40 centimeters, about 18,000 plants per mu, and the soil can be increased to over 20,000 plants.
Second, strengthen water and fertilizer regulation. When sowing can be combined with soil testing formula fertilization, appropriate application of phosphorus, potassium fertilizer, less nitrogen fertilizer. Generally, 45% compound fertilizer or about 15 kilograms of diammonium phosphate can be used in Mushi. You can use the seed and fertilizer machine to achieve one-time completion of sowing and fertilization. Before soybean flowering (unsealed ridge), special soybean or compound fertilizer is applied for about 10 kilograms per acre; when it enters an anthesis, it will be watered with drought, it can promote flowering and scab, increase the number of grains per plant, and pay attention to watering and Spray foliar fertilizer, watering can prevent 100-grain weight reduction, spraying potassium dihydrogen phosphate, foliar and other foliar fertilizer can prevent premature aging, increase grain weight. It is recommended to reuse 2-3 tons of organic fertilizer per acre before sowing wheat, rape, and other crops, while striving to return straw. When the rainfall is concentrated and large during the flowering season, the water should be drained in a timely manner. For the soybeans with prolonged growth, large groups, and tendency to grow in the early stages, early control can be made before the early flowering. Dilute-threonine 20 ml per mu is sprayed with 20 kg of water, or 15% paclobutrazol 50 g is watered 40- 50 kg spray.
Third, the rational use of herbicides. Herbicides should be used strictly in accordance with the specifications and recommended doses to avoid the occurrence of phytotoxicity or affect the growth of post-crop crops. After weeding, weeds are closed and weeding. Generally, we use 50% acetochlor 100-130 ml per acre. We can also use 72% Dole EC plus 3-5 grams of 20% sophosulfuron-methyl wettable powder and spray 50 kg of ground water. . In fields with a large field of straw, only the use of enclosed weeds often fails to achieve good control effects. Herbicides can be selected for post-emergence weed control based on soil conditions, weed species, and grass age. The control of monocotyledonous weeds mainly includes fine quizalofop-p-ethyl, gazocanas, and spermatozoids. The control of dicotyledonous weeds mainly includes kcalole and fomesafen. In the three compound leaves of soybean, 24% Kekule 30ml +12.5% ​​of the herb oil can be used per acre 30-35ml, and sprayed with 40-50kg of water to prevent monocotyledonous and dicotyledonous weeds. .
Fourth, timely prevention and control of pests and diseases. In recent years, the risk of soybean root rot in our county has been aggravated. In addition to the selection of disease-resistant varieties, 50% of Fuyou Mixture with 0.5% seeds or 50% Carbendazim with 0.3% seeds can be used for seed dressing. Phoxim and other pesticide dressing or pre-emergence bait killing, can control earthworms, earthworms and other underground pests; 10-20 days after emergence using systemic agents can prevent blackfly fly maggots. Imidacloprid and other pesticides were used to control sucking insects such as spider mites, aphids, whiteflies and leafhoppers. The use of organic phosphorus, pyrethroids and high-dimensional salts, avermectin in the middle and late stages can prevent and treat soybean bridge insects, leafhoppers, bean worms, aphids, Spodoptera litura, soybean mealworms, and borerworms.
Fifth, timely harvest. The optimum period for soybean harvest is at the beginning of ripening; the harvester should be equipped with a special harvester for soybean harvesting to reduce the impact of the reeling on the plants and reduce the loss of stalks. Correctly select and adjust the rotation speed and clearance of the threshing drum to reduce the rate of grain breakage. When the machine is harvested, dew should be avoided to prevent the grain from adhering to the soil from affecting the commodity.
