What vegetables are suitable for planting in Shenyang greenhouse at 0 and 5 degrees in winter?
Leek is usually planted in early March of the lunar calendar and transplanted before the Mid-Autumn Festival. When transplanting, you should be thinner, with five or six trees in a pool. The leek ground should have sufficient base fertilizer, loose soil, thin ridges, a border about five feet wide, soil moisture one foot wide and seven or eight inches deep, and the field should be cool.
Before sowing, soak willow leaves in water, add less kerosene, water them once, pinch out the moles and pick them up; If there are tigers on the ground, water omethoate. The favorite fertilizers for leeks are chicken and duck manure, human and animal manure, household dust or cake manure. When using cake fertilizer, rapeseed cake should be cooked first, diluted with water and then watered, and the best fertilization time is in the evening.
Leek is usually cut once every fifteen days, and it can be cut about 20 times a year. Leek should be cut in the morning or at night, and cut the mud with a sharp knife. When cutting, cut it in sequence. After cutting, rake the soil loosely with a rake, scrape a little of the thin side and cover it on the leek pile, and apply fertilizer once a day or two. Leek is drought-tolerant. If the weather is too dry, water it in the morning.
Try to strive for early germination and early listing of leeks. The previous winter, we should close the knife early, let the leaves of the tail knife die naturally, cover the leek with dung residue, miscellaneous ash and broken grass, and after the next spring, cross off the broken grass and large pieces, and then chase the dung, so that the first leek can germinate quickly. Leek has strong branching ability, and the newly planted leek can grow to 30 or 40 trees per pond in two or three years. If the density is found to be too high, transplant it in time.
