I. Variety selection Soybean varieties are regionally strong. Soybean varieties suitable for planting in Xuchang County include: Yudou No. 22, Xudou No. 3, Hedou No. 13, Zhonghuang No. 13 and so on.
Second, early sowing should be planted as soon as possible after summer harvest. If there is not enough sensation, it is necessary to step on the water. Sowing must be completed in early June. Try to avoid smashing.
III. Field Management at Seedling Stage
(1) Early seedling establishment: When the two cotyledons of soybeans are unfolded and the first pair of individual leaves emerge, artificial seedlings should be timely and in accordance with the density requirements. In the 13th yellow bean of Hedou, 9,000-10,000 strains are left, and 1-1.3 million strains are left in other varieties.
(B) cultivating soil: Soybean seedlings usually have 1-2 times of cultivating, with coordinated growth of ventilation, warming, and conservation. The first pass is carried out after the seedlings, and the depth of cultivating is generally no more than 3 cm. The second time the seedling height is about 10 cm, the cultivating depth should be 4-6 cm.
(3) Chemical weeding: When 2-3 composite leaves appear in soybeans, use 8.8% strawweed 40ml plus 24% Kekuile ​​EC 20ml/mu and spray 50kg water.
(4) Prevention of pests and diseases:
1, 2-3 true leaves, mu 50% carbendazim 30 grams plus 50 grams of potassium dihydrogen phosphate 50 grams of water spray, control soybean seedling disease, strong seedlings early.
2. Control of aphids and bean stalk flies: Use 40% of omethoate or 50mg of phoxim per acre and add 40kg of water spray.
3, downy mildew prevention and treatment: 85% of the use of metalloxacin or DuPont Kelu 100 grams per acre, add 50 kg of water sprayed foliar.
IV. Field Management at Flowering Stage:
(a) topdressing flowers and manure: early flowering acres of compound fertilizer 20 kilograms, or early flowering, full-foliage spraying foliar fertilizer to increase flower protection.
(2) Watering and waterlogging: The summer flowering period of summer soybeans has already expired. In case of drought, water must be poured. The soil is kept full (water holding capacity 75-85%) throughout the flowering stage.
(3) Prosperous chemical control: 50 grams of paclobutrazol 15% per acre is used at the beginning of flowering period, and 50 kg of watered leaves are evenly sprayed. To control leggy.
(IV) Prevention and control of pests and diseases: The main targets for prevention and control are grasshoppers, carnivora, bean worms, bridge-building moths and spider mites. The control method is the same as the control of seedling pests.
Second, early sowing should be planted as soon as possible after summer harvest. If there is not enough sensation, it is necessary to step on the water. Sowing must be completed in early June. Try to avoid smashing.
