How to grow cabbage? How long is the cabbage planting technique and how long is it grown

Cabbage is a very common vegetable in our daily life, also known as cabbage, which has strong adaptability, heat and cold resistance, and the planting effect is very good, and can be widely planted all over the country, and has a very high yield. Cabbage is also extremely nutritious and is one of the best foods in the world, so how do you grow it?

1. Sowing time.

Relatively speaking, cabbage is really adaptable, not only heat-resistant, but also cold-resistant. It can be planted in the open field in spring, summer and autumn, and can be planted in a greenhouse if the weather is cold. If you plant it in the spring, you can harvest it in the summer, and if you plant it in the fall, you can buy it in the winter and go to the market almost any time you go to the market.

2. Seedlings. When raising seedlings, pay attention to choosing a place with drier, better drainage, and more ventilation, so that the cabbage seedlings can grow well and be healthier. If you are raising seedlings when the weather is relatively hot, you should pay attention to some shading measures.

Wait until the seedlings grow out for half a month, you can carry out a certain amount of seedling work, and the row spacing is about ten centimeters.

3. Colonization. Before planting, we must pay attention to choosing a piece of land to apply foot fertilizer, about one acre of land to use 2000 kg of farm fertilizer, in addition, with some compound fertilizer. When the seedlings grow for a month, they can be planted, and be careful not to choose to do the planting work when the sun is relatively large, but to choose when it is cloudy.

Then pay attention to the density, and be sure to remember to water some water after planting, so that the roots of the seedlings can develop better.

4. Management. In the early stage of seedling growth, pay attention to the use of some nitrogen fertilizer, so that the plant can grow better. Then, in the late rosette, cabbage grows faster, and water and fertilizer must be indispensable.

In the later stage, it is mainly phosphate fertilizer and potassium fertilizer, and at this time there is no need for so much nitrogen. When the cabbage balls are in the late stage, don't water them too much, so as not to affect the taste.

In addition to this, we should also pay attention to the prevention of some diseases, in the autumn when the weather is better, there are some pests like cabbage moths, cabbage worms and the like, this is still based on prevention.

5. Harvest. When the cabbage grows up, it can be harvested, not necessarily the same batch grows well, the first harvest is relatively large, and it can be cut directly with a knife when harvesting.

Cabbage can be sown directly for sowing, or seedlings can be raised first and then transplanted. During the growing season, cabbage only needs to pay attention to proper watering and fertilization, without complicated management, and it is easier to plant.

Brad seedlings can be carried out in greenhouses, or with nutrient bowls and nutrient plates. Wait until the seedlings have grown to 3 or 4 leaves before transplanting. For transplanting plots, if the soil has good water and fertilizer retention capacity, it should be planted with flat furrows; Fields that are prone to water accumulation should be cultivated with ridges to facilitate drainage and irrigation.

Select some cabbage seeds with a relatively high germination rate, and spread the seeds evenly in the soil, and the gap between the seeds should not be too high. Appropriate application of organic fertilizers.

The cabbage planting techniques and planting times are as follows:

It takes 50-70 days for cabbage to be harvested from sowing to harvesting, and it is highly adaptable, so it can be planted in spring, summer and autumn, and can not be planted in the open air if it is cultivated in winter, but can be carried out in the greenhouse.

2. Planting technology:

1. Sowing method.

After the seedbed is arranged, the seeds are mixed with the soil and sprinkled evenly on the soil. Then cover the soil and control the sowing amount, generally about 50g per mu. The sowing amount should not be too much, otherwise it is easy to cause cabbage seedlings to affect each other's growth.

2. Seedbed management.

If cabbage seedlings are raised in winter, then we should pay attention to heat preservation. A week before sowing, the shed should be buckled properly to raise the temperature in the shed. After the cabbage seeds are sown, the temperature of the small arch shed is controlled at about 22 degrees, and the temperature at night is 15 degrees.

In a suitable environment, the seedlings can be planted in about 4 days.

After the seedlings are gathered, it is necessary to pay attention to proper cooling, carry out seedling refining, and avoid the phenomenon of tall seedlings. Then it is necessary to do a good job of thinning seedlings, and the spacing should be controlled at about 3cm, so as to improve the sufficient growth work for seedlings.

3. Seedling planting.

When the seedlings grow two true leaves, the seedling division work is carried out, and the nutrient soil must be prepared first, and then the nutrient bowl is prepared. Control the planting density for false planting, water properly after seedling, increase the temperature, the temperature is 18 degrees during the day, and the temperature is 10 degrees at night, and it is maintained for about 5 days. When the seedlings grow 7 true leaves, they can be planted, and the land preparation and fertilization of the planted field should be done before planting.

Mainly planted in flat furrows, the planting density was controlled, and the row spacing of the planting plants was kept at about 30x40cm. Finally, dig the planting hole and start planting, and the depth can be equal to the seedling mound and the furrow surface.

4. Water and fertilizer management.

After planting, it should be watered once to promote stable seedlings, and then watered once after about 5 days. Do a good job of cultivating, increase soil temperature, and enhance the growth ability of seedlings. After the rosette leaves grow, reduce the amount of watering, avoid the phenomenon of overgrowth, promote squatting seedlings, and control the squatting time according to the variety, for example, the early varieties squatting seedlings for about a week, otherwise they should squat for about half a month.

After entering the rosette stage, water reasonably, and increase the amount of water and fertilizer during the centering stage. Top dressing fertilizers are mainly urea and farm fertilizers.

Spring cabbage is sown in winter and planted in spring. In the northern region, seedlings are generally sown at the end of January and early February, and planted in the fields in early May. The cabbage is sown in mid to early May and planted in June.

Autumn cabbage is the main planting season, generally sown in mid to late June, planted in July and August, with high yields. Winter cabbage is sown in early August and planted in September.

How to grow cabbage:

1. Cultivate strong seedlings.

Before sowing cabbage, the seeds are mixed with sand and then sown. The seedbed should be thoroughly watered with water first, and after sowing, covered with a thin layer of soil. Seedlings should be raised in winter and spring, covered with mulch film to keep warm and moisturized, and covered with shade nets in summer and autumn to keep the soil moist, and remove the mulch after the seedlings emerge.

During the period of cabbage seedlings, the soil should be kept moist and attention should be paid to the prevention and control of pests and diseases.

2. Colonization. When the cabbage grows to six or seven leaves, it can be planted, and the large mound is planted in the field to reduce root damage. The base fertilizer is 5,000 kg of farmhouse fertilizer per mu, and 50 to 60 kg of compound fertilizer, and it can be planted after land preparation. After the cabbage seedlings are planted, they should be watered immediately to promote the slowing down of the seedlings.

3. Field management.

1. Watering. After the cabbage is planted, it is watered in time when there is a drought, and it takes about a week to slow down the seedlings. After the cabbage seedlings are slowed down, proper squatting of the seedlings can promote the root system. When cabbage enters the rosette stage and balling stage, it needs more water to keep the soil moist and conducive to balling.

When planting during periods of high temperatures, watering should be done in the morning or evening.

2. Top dressing. Cabbage needs 3 or 4 times of top dressing from planting to harvesting, especially after balling, the growth rate is fast and the nutrients should be sufficient. When watering after slow seedlings, 10 15 catties of urea can be used per mu. In the early stage of the rosette, the second top dressing is carried out, and 30 kg of urea can be used per mu, plus 10 kg of potassium sulfate.

In the early stage of balling, the third top dressing is carried out, and urea and potassium sulfate are also used. If there is a lack of fertilizer in the middle of cabbage balling, it should be topdressed again 15 days before harvesting.

3. The use of medium and trace elements.

Cabbage likes calcium, needs more calcium, and when calcium is deficient, dry heartburn, rotten leaves and rotten heart appear. In boron deficiency, the top of the leaf bulb is underdeveloped. In the early stage of cabbage balling, chelated calcium and borax solution can be sprayed, and sprayed 2 or 3 times continuously to prevent boron deficiency and calcium deficiency, promote balling, and improve yield and quality.

4. Prevention and control of pests and diseases.

Common insect pests on cabbage include cabbage worms, diamondback moths, etc., especially in summer and autumn when planting, which affects ball setting and increases the occurrence of soft rot. In the prevention and control, cyhalothrin and emamectin benzoate are used, which has a fast insecticidal speed and a long effective period. Cabbage soft rot is sprayed with chlorobromoisocyanuric acid, Chunlei Wangtong and other agents, mainly sprayed on the petiole at the base and the base of the stem.
