Early-maturing soybeans are favored by farmers and consumers because of their low production cost, easy cultivation, good efficiency, and rich nutrition. Now we will introduce the cultivation techniques of early-maturing soybeans as follows. (1) Suitable sowing, reasonable close planting, raising the yield in the early stage of protection cultivation in early February to early March sowing, open cultivation in mid-March to early July can be sown. Proper and close planting has an important role in increasing the number of knots, promoting the fullness of beans, and increasing the yield. Generally about 20,000 Mu seedlings, spacing 2222 cm, 7 to 8 kg per acre seed, seedlings promptly after the inspection seedlings, supplementary broadcast. Adopting protective cultivation can shorten the growth period, mention the morning market, and obtain higher economic benefits. (2) The application of P and K fertilizers and appropriate topdressing of nitrogenous fertilizers and soybeans require large amounts of P and K fertilizers. Therefore, the application of P and K fertilizers has a significant effect on the yield increase of soybeans. Phosphorus and potassium fertilizers are generally dominated by basal fertilizers, supplemented by topdressing. The amount of basal fertilizer should be determined based on the fertility of the soil. Generally, 100 kg of domestic compound fertilizer and 100-150 kg of plant ash are applied. The top dressing may be visualized as it grows during growth. Seedling stage, rhizobia have not yet formed, can apply 10%% of human fecal urine once; if poor growth before flowering, can apply 10%% to 20%% of human excrement 2 to 3 times, can also be applied 0.3% %-0.5% urea. Timely top dressing can increase production and improve quality. (3) Ensure that the moisture supply of edamame is a bean crop that requires a lot of water, but the requirement for moisture varies with the growth period. When sowing, the water is sufficient, the germination is fast, the emergence is quick and homogeneous, and the seedlings grow robustly. In mid-April, when the temperature is stable above 18°C, the cover film shall be removed in protective cultivation, and timely irrigation shall be performed according to the conditions of soil moisture, so as to ensure the growth and development of green soybeans and the need for water. Pre-harvest period and flowering and podging period, should not be too dry and wet soil, otherwise it will affect flower bud differentiation, resulting in reduced flowering, flower buds fall off. (4) Pest control The main pests of soybeans include soybean meal, soybean borer and yellow song stripe. Soybean pods were irrigated 1 or 2 times during the flowering stage of green soybeans to kill nymphs. The larvae are rolled and can be sprayed with a 40% by weight dimethoate emulsion 1000 times, or a 50% malathione emulsion spray. The main damage to the yellow-flesh beak is the leaves, which can be sprayed with 1000 times of dichlorvos. The disease of edamame is mainly rust. Rust prevention and control First, disease-free seeds or seeds can be used to disinfect the crops, followed by crop rotation to avoid heavy crops. Finally, at the beginning of the disease, 65% of triadimefon powder or 75% of chlorothalonil wettable powder can be sprayed at 600 times, sprayed twice at the seedling stage, and sprayed three times during the period of pod spray, each separated by 7 days. . (5) Harvesting early maturing varieties generally grab the morning market, that is, after entering the drum grain period can be gradually harvested, but can not blindly greed as early as possible, otherwise small beans, small commercial, poor production, but will reduce economic efficiency. Harvesting can be divided into 2 to 3 times, which can increase production and increase profitability. After harvesting, keep it in a cool place to keep it fresh.
