Onions are also called onions and onions. They are usually planted in early September in the first year and harvested in early June in the second year. The growing season is nearly one year. Do you know the best time to harvest onions? Today, Hui Nong.com will introduce you to the best time for onions.
The harvesting period of onion is the late stage of bulb expansion. At this time, no new leaves enrich the leaf sheath, which causes the pseudo stem to hollow. The onion will pour from the base of the pseudo stem. This is a sign of bulb ripening. The bulb of onion should be harvested in time after maturity. . It should be noted that the bulb ripening period is related to the characteristics of the variety, the planting time and the climatic conditions.
The harvest period varies greatly in different regions of China. For onion varieties with short dormancy and poor storability, harvest should be carried out in advance. When half of the plants fall down, they can start harvesting; while the mid-late ripe onion varieties should be harvested later, 70%. It is advisable to harvest the onion plants when they are lodging. Generally, the sign of suitable harvesting period is that the bulb is fully inflated, the outer scales are dry and semi-textile, the first two leaves of the base are yellow, the third and fourth leaves are still green, the onion pseudostems are dehydrated and soft, and the plants are The ground part is lodging.
If the onion is harvested too early, the bulb is not fully enlarged, which will result in low onion yield. At the same time, the water content of the bulb is high, it is easy to rot or sprout, and the storage difficulty will become larger. If the harvest is too late, the onion will become easy. Splitting the ball, especially when it is late for rain, the bulbs are not easy to dry, and the onions are hard to dry and more perishable. Harvesting should be carried out on sunny days, and it is best to have several consecutive sunny days after harvesting. At the time of harvest, the whole plant is pulled out and placed on the ground for 2 to 3 days. When drying, the bulbs should be covered with leaves. "Only drying the leaves and not drying the head" can promote the post-ripening of the bulbs and dry the outer skin. Then cut off the roots and dead leaves and remove the soil to store. Some also do not remove the leaves after harvesting, and then cod or bundle them for storage.
