Cultivation points of mung beans
Cultivation points:
(1) Site preparation. Mung bean is a deep-rooted crop, and the cotyledon is large, and the requirements for land preparation are strict. Before sowing, it should be deeply ploughed and finely sown, and the upper Panasonic should be solid and deep, otherwise it will affect the emergence of seedlings.
(2) Fertilization. Before sowing, the farmer's fertilizer is 2,500-3,500 kilograms, and the superphosphate is about 10 kilograms. If it is too late to fertilize, the appropriate amount of nitrogen and phosphate fertilizer can be applied in the early stage of growth to enhance the nitrogen fixation of the nodule.
(3) Sowing. Before sowing, choose a sunny day to spread the seeds thinly on the mat for 1 to 2 days to promote germination and emergence. The sowing method is mainly based on stripping, the row spacing is about 40 cm, the seeding amount is 1 to 1.5 kg per mu, and the sowing depth is 3 to 5 cm. If the soil moisture is poor after sowing, it can be suppressed once.
(4) Management. 1 room, fixed seedlings. When the seedlings grow two leaves and one heart, the "small seedlings" are removed, and four true leaves are fixed, and 1 to 12 million plants per mu are kept; 2 timely tillage. When the two leaves are one heart, a shallow cultivating is carried out to break the knot, remove the weeds, and enhance the activity of the nodule. When the four leaves are combined, the seedlings are cultivated for the second time. The fifth to sixth leaves are ploughed for the third time. When the head is put out and the arrow is dragged, the mulch is removed again, and the forage grass is completely removed. Topdressing, timely elimination of stagnant water in the rainy season, so that the soil is often in a loose and humid state to ensure the normal growth of the plant; 4 control pests and diseases. In recent years, the main pests and diseases of mung beans are leaf spot, mites, mites and pea pods. Prevention and treatment of mung bean leaf spot disease, sprayed with 40% carbendazim suspension 1000 times in the early stage of the disease, cockroaches can be made with 90% crystal trichlorfon to make bait, and aphids are sprayed with 40% omethoate 1000 times, pods螟 Spray with 40% isopropyl phosphate or 50% chlorpyrifos 1000 times in the presence of adult worms, all have good results.
