The harvest of shallots depends on the weather. Why is sunny day more suitable for harvesting shallots?

Cold dew is the17th solar term among the 24 solar terms. If the temperature drops in the future, dew will also appear on the ground. Then why is there an old saying in rural areas that "cold dew is hollow without peeling"? What does selling onions have to do with Hanlu?

Therefore, this 10 sentence "Cold dew does not cut onions, and the heart is empty" is for farmers who grow green onions to harvest before cold dew. Otherwise, it is easy to reduce the output of green onions. When harvesting green onions, it can avoid harvesting in the morning and evening when the temperature is low, and reduce leaf damage. After the green onions are harvested, they are dried in the dry land for half a day and tied with straw, which is beneficial to the transportation and preservation of green onions.

Dry waves stored in winter can't be harvested when the output of green onions reaches its peak. Because the leaves of green onions will wither slowly during storage, nutrition will be transferred to the false stems, and finally all the leaves will shrink, leaving only the false stems. The material loss is not serious, but the weight of scallion is obviously reduced.

Green onions are best stored in the harvest season after late frost and before the ground freezes. At this time, after cooling and frost, the branches and leaves of Welsh onion withered, the water content decreased, the mesophyll became thinner and drooping, and most nutrients were transported to the fake strips, which enriched the fake strips. Onions are harvested too early, and the branches and leaves are still growing. Onions are not strong, easy to be hollow, and cannot stand storage. If the harvest is too late, the stems of fake green onions will easily fall off and become soft, which will affect the yield and quality of green onions and will easily rot in the East China Sea.

When harvesting scallion, dig the scallion ridge with a big fork or shovel until the root of the scallion is exposed, gently pull out the scallion by hand, then dust it off and level the ground. Of course, it can also be harvested mechanically.

Note: First of all, when harvesting green onions, you can't pull them hard, which is easy to damage the false stems. Drainage or uprooting will reduce the commercialization and storage of waves. In addition, when harvesting green onions before "beginning of winter", we should avoid harvesting in the first frost. This is because if leaves meet with frost, they will become straight and firm. If the leaves are damaged, the water loss is serious during storage, and diseases are easy to occur. In this case, the harvest can be temporarily postponed until the temperature rises during the day and the branches and leaves thaw.
