Seed treatment to improve germination potential. Before sowing, choose the seeds with full grains for sunshine to improve the growth potential, and use 0.1%-0.2% ammonium molybdate or rhizobium (0.5 kg of fungus mixed with 10 kg of seeds) to mix the seeds at the time of sowing. According to the test, after the seed treatment of rhizoma formation early and more, fast growth, early branching, the fruiting rate and the number of full pods to improve the yield increase of 10% -20%.

Fine land preparation, adequate basal fertilizer. Deep plowing 20-25 cm, repeatedly harrowed and broken up turtleback-shaped ridge border 1.2 meters (paddy fields), dry slopes can be wider to prevent water rotting roots. In the first period, especially in the three-leaf period, soybeans especially need potassium and phosphorus fertilizer, so we should mu soil fertilizer 1500 kilograms, fire ash or grass ash 600 kilograms, 10 kilograms of phosphorus fertilizer, 20 kilograms of composite fertilizer, mixed as a base fertilizer, and then open the hole to sow seeds.

Choose to turn over the autumn seed, to ensure that a full seedling. Spring sowing is often met with low temperature and rainy weather, resulting in rotten seeds affecting the whole seedling. With a high germination rate, strong growth, can keep all the seedlings, and mature early, is the key to capture high-yield and stable production.

Early plowing and early fertilizer, to promote flowers and pods to prevent collapse and promote yield. Soybean is a favorite crop, slow growth in the seedling period prone to weeds, seedling height of 15-20 cm should be plowing weed cultivation to promote the development of rhizobium, cultivation to the cotyledonary node on the prevention of inversion; in the beginning of the branching period mu 5 kg of urea, 7 kg of potassium chloride, combined with the second ploughing under the enhancement of the number of effective pods branching.

Cleverly spraying inhibitors, hit the top heart to promote increased yield. In the flowering period with sodium sulfite 4-5 grams of water 50 kilograms, once a week, even spray 2-3 times, can enhance the intensity of soybean photorespiration, reduce the consumption of photosynthesis products; in the harvest 20 days before the removal of the top of the heart, can improve the fruitfulness rate of 7% -8%.

Prevention of diseases and insects, to protect plants and pods to protect earnings. Aphids, tigers, heart-eating insects in the first stage, the middle of the pod borer, twenty-eight star ladybug beetle and leaf spot disease, etc., endangering the young leaves, flower spikes, moth pods, should choose the counterpart of the pesticide in time to prevent and control.
