Out-of-season cabbage planting skillfully

Planting out-of-season agricultural crops and scientific management can shorten the world, save labor, and improve economic benefits. The editor tells you about out-of-season cabbage. First, select excellent varieties: mainly those with early maturity, high yield, high quality and strong heat resistance. Second, sowing seeds at the right time and raising seedlings in fertilizer beds: the seeds can be sowed from mid-April to late June, with higher terrain, convenient drainage, fertile and loose soil and sunny plots as seedbeds, which is required that cruciferous vegetables have not been planted in the previous crop. Ten days before sowing, the seedling bed is 1-1.5 meters wide, the length depends on the topography, the depth is 25-30 centimeters, and the ditch width is 40 centimeters. 100 kg of rotten organic fertilizer (or 40 kg of bio-organic fertilizer) and 2-3 kg of diammonium phosphate per bed. The seed amount per mu is 30 to 50 grams, sowing seeds evenly with fine sandy soil, and sprinkling 200 to 300 kilograms of dilute manure to cover the thin soil and water the wet seedbed. Then cover with a straw curtain (straw curtain). It is suggested that if the frame is covered with film, attention should be paid to timely ventilation. 3.

Pay attention to weeding, inter-seedling, elimination of sick and weak seedlings. 4. Transplanting and planting: (1) choose the land with good drainage and fertile land. (2) ploughing and ploughing, with a height of 15cm to 20cm, a width of 1m, and a ditch width of 25cm to 30cm, each planting 3 rows. (3) transplant vegetable seedlings with 5-8 leaves, and irrigate Nongjiaole 800 times of water after planting to reduce root injury, promote rooting and shorten seedling retardation time. Fifth, field management: timely inspection and replenishment of seedlings, early fertilization, combined with insect control spraying leafy vegetable days up to 2116 plus evil bully. In the rosette stage and heading stage, timely application of multi-compound fertilizer (or flushing fertilization), do not apply urea alone, early control of aphids, cabbage insects and other pests, choose pesticides to control.
