How to grow purple cabbage

Cabbage is a very common vegetable, but purple cabbage is still relatively rare in the market. Purple cabbage is a new cabbage vegetable introduced from abroad, also known as purple cabbage. Now there are many places where purple cabbage has been planted successfully. So how to grow purple cabbage? The following is the planting method of purple cabbage that the editor wants to share with you. Let's learn about it.

1. Region selection

Purple cabbage is more suitable for survival in a relatively mild climate, it has a certain cold resistance, but also can withstand a certain temperature, but the lowest temperature can not be lower than 5 to 8 degrees, the highest temperature can not be higher than 35 degrees, so this is why purple cabbage is relatively rare in the market. Then when we choose the planting land, we must consider these problems, choose the place where the temperature difference is relatively small, and the planting land should be relatively flat, fertile, convenient for drainage and irrigation, and at the same time in the place where transportation is more convenient.

2. Sowing and raising seedlings

Purple cabbage is usually sown from August to September every year, of course, the temperature of the planting ground has a lot to do with this period, so the sowing time can be arranged reasonably according to the temperature. at the same time, in a small number of areas, sowing can also be carried out around March of each year. The cultivation of purple cabbage usually needs to raise seedlings first and then transplant, and the topography of the seedling bed should be higher, and then the soil should be finer, and the seedbed should be watered thoroughly before sowing, which is conducive to seed budding. If you are worried that the temperature is too low, you can cover it with a layer of plastic film at the end to keep warm.

3. Seedling management

Purple cabbage will emerge about five days after sowing. If you have plastic film covering during sowing, you need to uncover the plastic film in time, and then check the growth of purple cabbage seedlings. If the soil on the seedbed is relatively dry, you need to replenish water in time, which is beneficial to the growth of purple cabbage seedlings. At the same time, we also need to check the growth of weeds in the seedbed and remove the weeds by hand. So as not to affect the growth and development of seedlings.

4. Reasonable close planting

Generally speaking, purple cabbage seedlings can basically grow five or six true leaves in about ten days, and then we can transplant. Then before this time, we need to prepare the planting land, fight as much as possible, fill up the depressions in the field with soil, and then sprinkle sufficient fertilizer, and then make ridges and ditches for planting, generally ensuring that 2000 purple cabbages can be planted per mu. So the best planting interval is 60 cm between rows and about 50 cm between plants. at the same time, the plant spacing can be adjusted according to the fertility of the soil.

5. Field management

After planting, the temperature in the field should be kept at about 15 to 20 degrees, so as to ensure the normal growth of purple cabbage, followed by timely watering, which is beneficial to the growth of purple cabbage roots. as the growth of purple cabbage needs a lot of nutrients, you need to see at least three or four times of topdressing in addition to the base fertilizer, and organic fertilizer, nitrogen fertilizer and fecal water can be used to promote its growth. But in the heart of the need to add the right amount of potash fertilizer, but also to avoid the lack of calcium in the soil, but also need to supplement the appropriate amount of calcium fertilizer. Each fertilization can be combined with ploughing and watering, which can promote the absorption of nutrients.

6. Pest control

The most common diseases of purple cabbage are black rot and soft rot, both of which are fungal infectious diseases caused by improper water management in the field, which seriously affect the quality of purple cabbage, so we can use neoptomycin for treatment. sometimes downy mildew and sclerotia disease occur, these two diseases basically occur in summer high temperature and rain, can be treated with chlorothalonil and Sclerotinia Jing respectively. Finally, the cappella will also appear some pests that harm the leaves of purple cabbage, such as aphids and cabbage insects, which can be controlled by 3500 times of permethrin.
