Planting knowledge: the easiest way to grow leek!

Leek is a perennial perennial root vegetable in Liliaceae. It is native to southeast Asia. It is cultivated everywhere in China, with strong adaptability, cold resistance and heat resistance. Many areas in the south can be produced perennially. Although the aboveground parts of the north have withered in winter, the lower parts of the land go into dormancy, and the topsoil can continue to sprout and grow after thawing in spring. Here is the planting knowledge: the easiest way to grow leek!

1. Soil preparation and fertilization

Leek seedling land should be easy to drain and irrigate, sandy loam or clay soil where onion and garlic vegetables have not been planted in the past 1 or 2 years, deep ploughing before winter, pouring frozen water, raking the top of the next spring to preserve soil moisture, applying rotten farm manure per mu, 5% phoxim granule per mu, adding dry fine soil 10~15kg, evenly spreading, shallow ploughing and fine raking, leveling the border, the border width 1.2 cm 1.5m, length 7m 10m, easy to manage.

(2) raising seedlings at the right time

Leek seedlings grow slowly and should be sowed early, and sowing seeds from late March to late April is suitable. After soaking seeds and accelerating germination, sowing is sowed in the seedling bed by wet sowing method, covering soil twice, covering a layer of thin soil at the first time, and then covering soil for the second time after returning to moisture, the total thickness of soil covering is 2cm, the amount of seeds per mu is 6~8kg, and the plastic film is covered after soil mulching, so as to increase temperature and preserve soil moisture, and remove the plastic film after emergence. Generally, 1 mu of seedlings can be planted in a vegetable field of 7 mu.

III. Seedling field management

Leek seedling height 5cm light watering, timely soil loosening, after 10cm, can be combined with watering mature manure or urea 2 times, and along with the water flushing application crystal trichlorfon per mu 0.5~1kg, to kill leek maggots and other pests, seedling height 15cm control irrigation, to prevent overgrowth lodging, weeds should be pulled out in time, when the seedling height 12cm is about 0.5kg 0.75kg 25% herbicide per mu Or use 0.15kg 33% herbicide EC spray to treat the surface before emergence after sowing.

IV. Rational planting

For planting leek, select the plot where the soil is fertile and convenient for drainage and irrigation, apply rotten farm manure 43.5 cubic meters per mu, level off to make a border, the width of the border is 2cm, every group of 3, set up a cold protection zone 1 meter wide on its north side, transplant it from late June to early July, cut off the end of the fibrous root before planting, cut off the end of the fibrous root before planting, flat border hole planting, row spacing 13~20cm, hole spacing 10~15cm, 6 million plants per hole, planting without burying leaf sheath is appropriate. Be steadfast after planting and water in time.

V. Field management

After the new leaves of leek are issued, the seedling water should be watered slowly, and the soil moisture should be preserved by ploughing, keeping the soil dry and wet. after autumn, when the leek is in the most vigorous period of growth, it is necessary to fully supply fertilizer and water, then the temperature gradually decreases, the plant growth is slow, and the surface is not dry. Leek needs medium light intensity, strong shade tolerance, but weak light, less photosynthate accumulation, few and thin tillers, low yield and easy premature senescence. The light is too strong, the temperature is too high, there are many fibers, and the quality is poor.

VI. Timely harvesting

The yield of leek is relatively low in the first 1-2 years after planting, and the yield is the highest in 3-6 years. When it enters the senescence stage after 10 years, it should be divided and transplanted in time. The number of harvests each year depends on the growth, fertilization and market situation of leeks. The best harvest in the early morning is 7 leaves and 1 heart, and it is appropriate to cut to the yellow leaf sheath of 3~4cm on the bulb. After each cut, each knife should be slightly higher than the previous stubble. To ensure normal growth.
