2, planting methods. Whether it is spring sowing or summer and autumn sowing, it is cultivated by double ridges with high ridges. The ridge distance is 1.1-1.2 meters and the height is 25 centimeters. The mulch is 90-100 cm wide on the top of the ridge (the effect of the mulch film is better in autumn), and the soil pressure is strict around the membrane. After paving the membrane, dig a hole at a distance of 30 cm on both sides of the ridge. The depth of the hole is about 5 cm. After sowing water, 2-3 seeds per hole. After the sowing, the mulch around the hole was tightly covered. Before the ridge, it is necessary to apply the base fertilizer, and it is suitable to apply 3-4 cubic meters of high-quality crude fertilizer and 30-40 kilograms of compound fertilizer per acre. 3. Water and fertilizer management. On the basis of the application of the base fertilizer, the cowpea seedlings are no longer topdressing, and attention should be paid to controlling the watering. After flowering and pod-forming, combined with watering, apply a small amount of quick-acting nitrogen fertilizer, about 10 kg per mu of urea, and once every other water. 4, insert frame and lead vine pruning. When the plants start to grow, they will insert them in time, and pay attention to the vines. When the main vine is about 1 meter long, 2-4 side vines can appear at the base. The side vines of the base should be completely destroyed to avoid causing the lower layer to be covered. The lateral branches formed in the upper middle part can be podded in 2-3 knots, and can be topped after pod formation. When the main vine grows to the top of the frame and exceeds 30 cm, the fine shoots are all used to knock off the young shoots, ensuring that the shelves are bright and light, and the middle and upper layers can be re-established. 5. Pest control. Luojing 99 has strong disease resistance, and no need to spray fungicides in spring and summer. However, in autumn, a rust spot and powdery mildew occurred in September, and it can be sprayed with rusting 2-3 times. For aphids, pea pods, sassafras, etc., it is necessary to spray the medicine in time, especially in the autumn, and should pay attention to the broad-spectrum insecticides such as spraying and sweeping.

The main points of cowpea cultivation technology
1. Sowing date. Due to its wide adaptability, this variety can be sown at any time in the Huang-Huai-Hai area from Qingming-Great Summer. In general, spring sowing is suitable for Qingming-Guyu; summer sowing is suitable for summer solstice-small summer; autumn sowing is suitable for the end of July-July.
