Growth habit of leek

Leek is a perennial root vegetable of Liliaceae, which has strong adaptability, cold resistance and heat resistance and is cultivated all over China. Many areas in the south can be produced all year round. In the north, although the aboveground part dies in winter, the underground part goes into dormancy, and the topsoil germinates and grows after thawing in spring.

Leek is cool, cold-resistant and heat-resistant. The optimum temperature for seed germination is above 65438 02℃, and the growth temperature is between 65438 05℃ and 25℃. The underground part can withstand lower temperatures.

Moderate light intensity and strong shade resistance. However, the light is too weak, the accumulation of photosynthetic products is less, the tillers are few and weak, the yield is low, and it is easy to premature aging; Too much light, too high temperature, too much fiber and poor quality.

Harvest of leek:

The number of times leeks are harvested each year depends on the growth, fertilization and market situation of leeks. In winter and spring, leeks can be harvested three times in the arch shed. Although the quality is good in autumn, it is suitable to harvest L-2 crops in order to cultivate rhizomes and lay a material foundation for the growth of arch shed.

Leek is cut with 7 leaves 1 heart as the standard. Harvesting in the morning is the best. It is appropriate to cut the yellow leaf sheath 3-4cm above the bulb. After each cut, it should be slightly higher than the previous crop to ensure normal growth. The yield of 1-2 before planting is low, and the growth period is 3-6 years, and the yield is the highest. /kloc-enter the aging stage after 0/0 years, and transplant it in time.
