After the winter temperature drops, cultivation of leeks needs to be insulated with sheds. The field management techniques during the shed period are briefly described below. Before the shed (1) clean the bowl. In early November, the leeks began to dry after several frosts. At this point, the stalks, dead leaves, weeds, etc. in the razor clam should be cleaned to reduce the source of disease and overwintering pests. (2) Piers. After the Qing Dynasty, the topsoil above the leek bulbs was dug out to expose the bulbs, and the sun and the night were frozen to break the dormancy earlier, to make the puppies neat, and to eliminate the pests that infiltrated the puppets during the winter. Be careful not to hurt the roots while you are crouching. (3) irrigation roots. 6 to 8 days after the pier, 50% phoxim EC or 90% crystal trichlorfon 1000 times 80 kg is used to root the roots to prevent damaging. (4) timely fertilization. After irrigating the roots for 3 to 4 days, fertilize the rows between fertilization, apply 2,000 to 3,000 kilograms of organic fertilizer per acre, or 250 to 300 kilograms of cake fertilizer. After fertilization, cover the soil, flatten the soil surface and smashing the pier, and then water the soil. Then cover a layer of fine soil to bury the pier.
After the shed (1) temperature management. After the leek shed, the larvae can emerge after about 25 days. After the emergence, the shed temperature is controlled at 20-25°C during the day and is kept as much as possible during the night. (2) Timely soil. When the seedling height is 6 to 7 centimeters, the soil is first cultivated, and the soil height is 3 to 4 centimeters; when the seedling height is 10 to 15 centimeters, the soil is cultivated for the second time, and the soil height is 6 to 7 centimeters. (3) fertilizer and water management. Cutting knife is not watering before cutting leeks, two knife leeks 6 cm high, combined with water per acre compound fertilizer 20 to 30 kg, 4 to 5 days before harvest watering. After each cut, the bulbs must be sprayed to dry the bulbs. After the new leaves are grown, they are mixed with water to fertilize the soil.
