Comparison of seedling transplanting with spring soybeans and direct seeding cultivation, the main advantages: It is conducive to the early growth of soybean, reduce the rotten seedlings, can lay the foundation for high yield; can mature 10 to 15 days earlier, favorable for sale on the market.
Selection of good varieties of large grains, delicious, dense seeds, pods and seeds are green varieties when harvested. For example, Taiwan 292, Beifeng No. 3, Zhongdou 30 and other soybean varieties, if there is no special varieties can also choose to use short legs early, Xiangchun bean No. 10 and so on. The amount of mu is 6-8 kg.
Film seedlings can be planted twice. In general, the “seizure†can attract the first batch of sowing seeds; the sandy soil or dry soil with good leeward sunshine, loose soil, and good drainage is used as the seedbed. It is not appropriate to use clay loam with poor permeability because the clay loam is likely to cause seedbeds. The stagnant water causes rotten seedlings; the seedbed can be made into a 140 cm wide box, which is convenient for covering the film and raising seedlings during transplanting; the seedling bed is deeply turned, fined, and flattened and sowed. Generally, a 3.5 meter long box can be sown. Kilograms; After sowing is finished, cover with a fine soil, if the soil is dry, you can pour water once, so that the surface of the car is soaked; it is also appropriate to cover some straw, have heat preservation and moisturizing, and reduce the dead seedlings caused by soil compaction. Function; cover species, with a small bamboo rod 2 cm long by about 1 meter distance in the car surface do arch, covering the film, around the compaction with the adobe; the first batch of seedlings after transplanting, in time for the second batch of seedlings in the original Seeding, seedlings transplanted at the 2 leaf stage in time; strengthen the management of heat preservation, moisturizing, anti-staining, weeding, and hardening seedlings during the seedbed.
Transplanting at the right time chooses sunny slope soil or mountain dry land, when 50% of the seedlings in the seedbed are transplanted to the 2 leaf stage, it is best to grab transplants after the rain; before transplanting, turn the soil deeper and then complete, then According to a 33 cm wide row spacing, the ditch is 15 cm wide, and then 2 rows or 1 row of seedlings are planted on the both sides of the ditch at a spacing of 20-25 cm; when transplanting, 20 kg of phosphate fertilizer and 10 kg of ash per acre can be used for transplanting. The amount used as base fertilizer.
Careful management After transplanting, we will strengthen the management of middle cultivators, topdressing, weed control, and pest management. Generally when the seedling height 20 to 30 centimeters in time cultivator weeding; best before the rain, combined with the cultivator as the seedlings, according to the amount of 7 to 10 kilograms of urea per acre application of Miao Fei; generally based on the actual situation of drug prevention and control of rat damage 1 , control locusts, pods, stinkbugs 2 times; prevention and treatment of insect pests should be selected for safe human and livestock chrysanthemum pesticides, requiring uniform medication, centralized use.
