Early-maturing soybeans, also known as "spring green" soybeans, are edible soybeans. It belongs to a new variety of green soybeans and is an indeterminate type. The main features are early maturing, high yield, and high quality. Spring sowing has a total growth period of 80 days, which is a partial early maturing variety. It is mature 15 days earlier than the Taiwanese variety “75-1â€, yields 12.6% higher, and has superior quality. The beans have high sweetness and good palatability, and they have a good taste and a good taste. As a vegetable in the early spring, it is a medium and large shed, a small ring, a 1-2 year old orchard, and other multi-crop crops. The ideal economic crop. The main cultivation techniques are as follows:
First, the sowing period. Edamame is a thermophilic vegetable, which is normally planted in open field in early April and can be harvested in late June. The use of plastic film and small ring shed cultivation in late February sowing, film cultivation in the middle and late March sowing, early spring large and medium shed cultivation can be planted in advance to late February, early May can be listed, per mu production value of 2000-3000 yuan.
Second, rational dense planting to ensure the whole seedlings. "Spring Green" plant height in the 50-55 cm, the general density of about 20,000 per mu, spacing 40-50 cm, spacing of 15 cm or so, sowing 2-3 per hole, sowing before planting 1-2 days. Such as ditching seedlings, the next species can not be too deep, 2-3 cm is appropriate, about 7.5 kg per acre species.
Third, Shizujifei, appropriate fertilizer. Although soybeans have a nitrogen-fixing effect, proper application of fertilizers can increase the number of individuals and increase the yield. Each mu of composted organic fertilizer is 1,000 kg, superphosphate is 15-20 kg, or ternary compound fertilizer is 40-50 kg, which is turned into soil. Do it. Topdressing applies 10 kg of urea per acre at the beginning of flowering. Potassium dihydrogen phosphate may also be used for foliar application.
Fourth, strengthen management and clear the ditch system. Soybeans are dry farm crops, and they must be well-flooded. The three ditches must be matched, and the rain should stop and the water in the ditch should be no more.
Fifth, pest control. After sowing, 86% of acetochlor EC can be used to dilute 35 kg of water per 100 ml of acre. After soil sowing is repeated, ground soil is closed. During the seedling stage, virus A protection and attention can be paid to the control of aphids.
