Leek harvesting skills
Amaranth is a perennial vegetable that can be harvested several times a year. To prevent the premature decline of leeks and achieve high yields year after year, the number of harvests should be carefully controlled in the production, and the harvesting and raising of roots, front knife and back knife, current year production, and year-round yield should be handled properly. relationship. First, harvest time and times The number of harvests per year should be based on plant growth, soil fertility and market demand. The leeks planted in that year are not suitable for harvesting. The harvest after the second year is mainly based on spring hoe. Spring hoe has good quality and high efficiency. Generally, it can harvest 3-4 times from April to June. Summer heat, slow growth of leeks, poor quality, in order to raise the roots, only to receive pods and flowers. Autumn leeks are of better quality, but generally they are only harvested 1-2 times for wintering. For cultivation in protected areas, it can be harvested in the fall and covered in winter. The number of days between harvests of leeks should be determined based on the growth of plants, climatic conditions and market demand. In the spring, generally from the turning green to the first knife harvesting about 40 days, the second knife interval 25-30 days, to the third knife interval 20-25 days, plant height 30 cm, 7 leaves 1 heart when harvested. The harvest is too early, the plants are susceptible to premature senescence and the yield is low; the harvest is too late, the plants are easy to fall down and the quality is poor. Second, the harvesting method Leeks are best harvested in the early morning to keep the product tender. It is advisable to keep 3-4 cm above the ground when harvesting. Keeping pods is too high and the yield is low; leaving pods too low affects the tillering and growth of the plants. Each year, harvesting should be about 1 cm higher than the previous one, which is beneficial to the growth of the jaw.
