The latest spring cabbage seedling technology tutorial

Vegetables are an indispensable food in many people's daily life, and cabbage is also welcomed by many people. As a spring vegetable, cabbage has a very large planting area in China. When planting cabbage in spring, because the temperature is still relatively low, so the seedling work is very important. So how to raise seedlings of spring cabbage? Today, the editor has brought you the seedling technology of spring cabbage. Let's take a look at it.

1. Select superior species

When raising cabbage seedlings in spring, we should first select a good variety. As I just said, the temperature in spring is still relatively low, and it is easy to appear cold in late spring. Therefore, when we choose varieties, the first thing is to give priority to seeds with strong cold tolerance and strong disease resistance. For example, Chunqiang, Zhonggan 21 and so on, these varieties have the advantages of early maturity and high yield. It is very suitable for planting in spring, and the selection of high-quality varieties is also the key to ensure the success of spring cabbage breeding, so we should pay more attention.

2. Seedbed preparation

After selecting the variety, we need to get ready for the seedbed. Cabbage nursery bed with sufficient fertility, the previous crop is not cabbage, cabbage and other similar vegetables. The new garden soil can be used to raise seedlings, and sufficient base fertilizer should be applied in the seedling bed at the same time. The base fertilizer is mainly rotten farm manure, combined with an appropriate amount of compound fertilizer. Inorganic fertilizer should be evenly spread to the soil for deep turning and raking, so as to improve soil fertility. If it is a sunny bed to raise seedlings, then the border should be covered with some plastic film, about half a month later, when the ground temperature gradually rises before sowing.

3. Sowing seeds at the right time

We should determine the sowing time according to the planting area, for example, when planting in North China, the best sowing time is from December to January of the following year. The seedlings are usually raised in solar greenhouse and improved sunny beds, which are very beneficial to the growth of cabbage seedlings. Then the planting density should be determined according to the variety. if it is an early-maturing variety, it will be planted about 4500 plants per mu, while the middle-maturing variety will be reduced by about 500 plants. Cabbage seeds generally do not need to sprout, can be directly sowed into dry seeds. However, the seedling beds should be poured with sufficient bottom water, and the seeds should be scattered evenly. After sowing, they should be covered with a layer of fine soil to preserve moisture, so as to prevent the seedling beds from cracking due to lack of water.

4. Seedbed management

Before emergence, the temperature should be kept at about 20 degrees. Generally, seedlings will emerge about 5 days after sowing. After emergence, we should pay attention to do a good job of wind prevention, and then reduce the temperature to about 15 degrees. If the growth of seedlings is too dense, then it is necessary to do a good job of interseedling work to avoid excessive growth of seedlings. Then, when the seedlings grow to about 3 true leaves, the seedlings should be divided again, and the temperature of the seedling bed should be kept within 10-20 degrees. Then it is necessary to refine the seedlings at low temperature before the seedlings are planted in March, which can appropriately increase the ventilation rate, make the seedlings adapt to the environment of the field in advance, promote the slow seedling and improve the survival rate of the seedlings.

The above is a brief introduction to the breeding technology of spring cabbage. This is the end of today's introduction, this article is for reference only, friends who want to know more relevant information, please continue to follow us!
