Six common varieties of cabbage, how to raise seedlings of spring cabbage?

Cabbage is often seen on our table. There are many kinds of cabbage. I don't know how many kinds we have eaten. Next, the editor will tell you about the six common varieties of cabbage, as well as the breeding methods of spring cabbage.

I. six common varieties of cabbage

1. Kale

The biggest difference of kale is that it does not bear balls in the center, it is mainly used in garden art, and there are different colors, such as emerald green, dark green, yellow-green, purple-red and so on, but kale is mostly found in the United States and is loved by Americans.

2. Kale

Cabbage is a mature ball in the middle, the outer leaf is still dark green, the ball is stable, the ball is large and compact, the growth is good, the yield is high, the disease resistance is strong, the heat and water resistance is good, so it is suitable for planting in many areas.

3. Kale

The leaf ball of kale is oblate, the outer leaf is dark green, the ball color is bright green, medium growth, wide adaptability, heat resistance and cold resistance, relatively larger than kale, suitable for planting in flat land.

4. Brussels sprout

Brussels sprouts are generally grown along the Mediterranean coast, and their heads are relatively small. It usually takes several plants to cook a dish, but they are very high in protein. With the development of science and technology, they are also grown in Taiwan.

5. Brussels sprouts

Kale leaves are not as smooth as other kale, have a lot of wrinkles, the leaves can bear balls when they are young, it is not as smooth as other kale, but it is more delicate, softer and more nutritious than other cabbages.

6. Three seasons of green cabbage

The outer leaves of three-season green cabbage are turquoise, the ball leaves are dark green, and the surface is smooth, which is mainly produced in the area around Xingtai. The reason why it is called three-season green cabbage is that it can be planted in spring, summer and autumn.

2. Seedling raising methods of spring cabbage

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.

Well, that's all for today's editor to share with you. From the above, we can know that there are still many varieties of cabbage. The editor mainly told you about the four common ones. I don't know which one you think is more delicious. If you want to plant spring cabbage, you can learn from the breeding method of this article.
