How to increase the yield of green onions

Green onion is widely used in China, and it is a kind of side dish that many people like very much. The planting area of green onions is the largest of all the side dishes. When planting green onions, many people attach great importance to the yield, because the yield is directly related to the planting efficiency. So how can we increase the output of green onions when we plant them? Let's take a look at it with the editor.

1. Soil management

Soil is the key to ensure the healthy growth of green onions. We need to choose a suitable planting soil before planting. To ensure that the soil is thick and soft, rich in organic matter, good soil moisture, etc., can ensure the healthy growth of green onions, which is obviously helpful to improve its yield. After the spring onion seedlings are unearthed, in order to prevent soil consolidation from affecting the growth of green onions, it is necessary to do a good job of weeding and weeding and improve the permeability of the soil. Then we should regularly observe the soil conditions and the growth of green onions to ensure the normal growth of green onions and increase the yield.

2. Water and fertilizer management

The root growth ability of Welsh onion is relatively weak, and the root distribution is also relatively shallow. Therefore, the demand for water is relatively large, and the soil moisture should be kept at about 70% in order to ensure the normal growth of green onions and increase the yield. However, water should not be too much, otherwise it will easily lead to root rot of green onions, cause a variety of diseases and insect pests, and affect the production of green onions. The demand of green onion for nitrogen, phosphorus and potassium is more balanced, more nitrogen fertilizer should be applied in the early stage, and phosphorus and potassium fertilizer should be applied in the later stage. If the phosphate fertilizer is insufficient, it will affect the normal growth of green onions, and the yield will also decrease.

3. Attention to planting.

There are also some aspects that we need to pay attention to when planting green onions. When planting, we should pay attention to distinguish between large and small seedlings, remove weak dead seedlings, diseases and insect pests and other bad seedlings. To avoid the consumption of nutrients and affect the growth of other normal seedlings, we should pay attention to the strength when planting to prevent injury, resulting in poor growth of green onions. And also pay attention to the depth, should not be too deep and too shallow, too deep will have a great impact on seedlings, and too shallow will reduce the length of green onions, affecting the value of goods. Finally, we should pay attention to the planting density, which is not only convenient for management, but also beneficial to the growth of green onions.

4. Pest control

The effect of diseases and insect pests on the yield of green onions is very serious. If you do not do a good job in the prevention and control of diseases and insect pests, serious cases can lead to no harvest of green onions. Therefore, to do a good job in the prevention and control of diseases and insect pests is also one of the ways to improve the yield of green onions. We need to understand the specific diseases and insect pests of green onions, and then know some basic symptoms. It is convenient to know the specific diseases and insect pests in time after the onset of the disease and carry out symptomatic treatment. Of course, the prevention and control of diseases and insect pests is mainly based on prevention, strengthen management and reduce losses.

The above is a brief introduction to how to increase the yield of green onions. The output of green onion is closely related to the planting benefit, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
