What does the rural proverb "light snow collects onions, but if it doesn't, it will be empty" mean?

Agricultural proverbs are the true knowledge gained by farmers from generation to generation in practice. In fact, there is some scientific truth in this, just like the subject said? Snow collects onions, or is it empty? It has been affirmed in production practice.

The first thing to know is that Xiaoxue is165438+1October 22nd.

The quality of scallion reached its peak in the middle and late June at 5438+065438+ 10. During this period, the nutrients in the leaves of green onions are transported to the body of green onions, so that green onions can grow in large quantities. It is neither too early nor too late to harvest green onions. If the harvest is too early, the green onions have not fully grown. At this time, the output of scallion will be lower, and the scallion will be soft and hollow. Green onions have a strong respiratory function, consume a lot of nutrients, and are not resistant to storage. If the harvest is too late, the water of the scallion will be lost, and the scallion will become soft, which will still affect the yield and reduce the quality of the scallion. Another point is that if the harvest is too late, the green onions will be frozen and rot.

Therefore, the harvest time of green onions is one or two days before and after the light snow solar term. Whether it is postponed or advanced, the green onions are not there, which means nothing is gained. The scallion is soft and unreal.

My hometown is the north, and it's time to harvest green onions recently. It's a whip onion, which is very long, thick and solid, and tastes sweet and spicy. Onion seedlings are all raised by themselves. They are sown in autumn, and after a winter, they are sown from the middle and late June to the early July of the following year. The appropriate period of colonization should not be too early or too late. If transplanted too early, the onion seedlings will be too small and the ability to absorb nutrients will be too poor, resulting in slow growth of onion seedlings. If transplanting is too late, onion seedlings are easy to grow wildly, it is difficult to plant seedlings during transplanting, and it is easy to break and hurt seedlings and prone to lodging. In addition, when it is rainy in the slow seedling stage, high temperature is easy to infect diseases, leading to rot and even death of retting roots.

Before transplanting scallion, soil preparation should be done as early as possible, and sowing should be done at a suitable time, so that the scallion seedlings will turn green slowly before rainy season and high temperature weather come, and the scallion plants will form strong roots before the early autumn turns cold. In this way, green onions can quickly enter the growth period, accumulate more nutrients, and ensure the quality and yield of green onions.
