Chinese cabbage cultivation technology and precautions

When planting Chinese cabbage, we must pay attention to the watering of water, and the land should not be too dry. Because Chinese cabbage is very much in need of water. If there is no excessive water for irrigation, the Chinese cabbage will become wilted.

And also pay attention to prevent pests and diseases。Because there are often a lot of insects on the leaves of Chinese cabbage. So in order to prevent these bugs, cabbage should be sprayed with a lot of pesticides.

Try to spray some pesticides that are not harmful to the human body. Because the leaves of Chinese cabbage are really something that insects like very much. For example, if some people pick Chinese cabbage at home, there will be a lot of bugs on it.

Because they don't spray too many pesticides in their own homes. So it's a bug paradise. Be sure to pick the bugs well before eating, there are not only small but also large bugs.

Nowadays, many people like to eat Chinese cabbage when eating barbecue, because Chinese cabbage is very simple. In the diet of northerners, cabbage occupies a high place. Because this is one of the few vegetables that can survive in the north.

Many people in the Northeast will stock up on hundreds of catties of Chinese cabbage when they are about to enter autumn. They will use all these Chinese cabbages to pickle sauerkraut. Prepare for winter.

Because in the old days, there were no vegetables in winter. So you can only rely on these stored Chinese cabbages to eat some fresh vegetables in winter. However, now the transportation is more convenient, and vegetables from the south can be transported in, and the north can eat cheap and affordable vegetables even in winter.

However, Chinese cabbage is still a very popular ingredient. Because people are used to eating this vegetable. It doesn't have any strange taste, and whether it's stewed or stir-fried, it's very delicious.

It's just that when Chinese cabbage is surviving, there are still many problems that should be paid attention to. This requires the grower's own experience. Fertilizing these vegetables is also a better choice, which will only benefit the growth of these vegetables.

It's just that these dishes are not organic produce. We should still use less harmful pesticides.

We must pay attention to the temperature, pay attention to the quality of the seeds, we must choose the right seeds for planting, the soil must be exposed to the sun when planting, play the role of disinfection and sterilization, we must manage it in accordance with scientific methods, and we must pay attention to fertilization and watering.

When planting Chinese cabbage, we must strictly prevent rainwater, do not let the rain soak the roots, and pay attention to disease prevention at ordinary times, spray relevant drugs once a week, and deal with diseased plants in time to avoid infection.

When planting Chinese cabbage, we must pay attention to preventing pests and diseases, there will be rotten roots, proper fertilization, proper watering, and pay attention to soil moisture.

Plant at the right time, maintain the right temperature, replenish water and fertilizer in time, don't break its roots, and harvest it in time.

The weather, the temperature, and the soil, whether there are nutrients, whether there is moisture, whether there is fertilizer, whether there is pesticide spraying on time, and also to distance yourself.

What are the key points of cultivation techniques of Chinese cabbage in <>? What are the issues to be aware of? The best way to grow organic bok choy is to choose:

Far away from mines, hospitals, and traffic roads, there is no pollution source, and the atmosphere, water source, and soil environment must meet the production standards of organic vegetables, and the environmental monitoring department has evaluated the best. The land requires deep soil, fertile (natural), after recuperation and purification, that is, no chemical fertilizers and pesticides have been applied within 2-3 years, mainly organic fertilizer, and weakly acidic land. Organic Chinese cabbage seeds cannot be genetically modified, although genetically modified seeds produce higher yields of vegetables, but are not suitable for organic vegetable production.

The production of Chinese cabbage is generally based on autumn and winter, and the main varieties are: Tianjin Qingma leaf series), Yutian Erbaojian, Yuqing, Beijing New No. 3, etc. It depends on personal positioning.

Planting conditions: Organic Chinese cabbage cannot be planted continuously, and can be planted in rotation with field crops and onion and garlic vegetables. Cultivated Chinese cabbage should be sown with early-maturing varieties, and after early harvest, deep ploughing of the soil layer, autumn stubble cultivation of Chinese cabbage can greatly reduce the occurrence of pests and diseases, increase yield, and improve economic benefits.

Fertilize; It is forbidden to use chemical fertilizers, and the use of organic manure and biological organic fertilizers recognized by organic certification agencies can not only meet the needs of the growth and development of Chinese cabbage, but also maintain the original flavor of Chinese cabbage, and can also reduce inputs, improve the soil environment, and cultivate soil fertility. Watering; In fact, it is relatively simple, and no pollution can be done.

The cultivation technology of Dabailai is not difficult, in the countryside The general farmers basically (referring to the conditional areas) have planted Chinese cabbage, and the varieties generally planted are convenient for winter storage in the past, generally that is, the kind of Baotou or a kind of hemp leaf vegetable, the growth period is relatively long, generally sown in the autumn after the wheat harvest, and harvest before the light snow. Now it is different from the past, the new varieties of new cultivation are on the market every year, now the cabbage is mainly planted to follow the market demand to choose varieties, a year can be sown two seasons to obtain higher benefits, no matter the season to pear first, and then fertilization, according to the geological conditions of the moderate application of farm fertilizer and compound fertilizer, cabbage likes potassium fertilizer and nitrogen fertilizer. Then the ground is raked and leveled, and the mulch film is spread.

There are two methods of scattering seeds and seedling transplanting in autumn, and most of them now use transplanting seedlings to plant, because this can not only save the spare time of the field, but also help to protect the seedlings, which is relatively economical and practical. At the same time as planting seedlings, timely irrigation to ensure the survival of seedlings, subsequent irrigation should be flexible and timely spraying pesticides. Ensure the safe growth of Bellow.

It is necessary to choose excellent Chinese cabbage varieties, try to choose film coverage or greenhouse planting in the planting process, ensure sufficient sunlight, loosen the soil in time to make the nutrients fertile, and water in time. It is necessary to pay attention to the connection management in this process, spray pesticides in time, and avoid serious pest and disease disasters and let the leaves of Chinese cabbage rot.

Cultivation temperature, cultivation density, planting spacing, management methods, fertilization frequency. It is necessary to pay attention to some problems, as well as some diseases, but also to pay attention to the problem of pampering, and also to pay attention to the maintenance of Chinese cabbage. Pay attention to the growth of Chinese cabbage.

Be sure to pay attention to the planting time, generally speaking, early-maturing varieties are sown in early August, late-maturing varieties should be sown in late August, and base fertilizer should be used to prepare the land in advance to ensure the organic matter content in the soil, and sandy soil should also be selected.

Chinese cabbage is generally planted in early August, Chinese cabbage is generally planted in the way of direct seeding or seedling transplanting, Chinese cabbage does not have high requirements for soil, and can adapt to a variety of environments; It is necessary to pay attention to the seedlings of Chinese cabbage in time after emergence, and Chinese cabbage is generally seeded once every three days or so.

<>1. Cabbage is suitable for planting between July and August every year, and the temperature is suitable for the growth of cabbage in the middle of summer.

2. According to the actual growth area, choose the varieties of seeds suitable for planting, the seeds should be fresh and shiny in appearance, and the seeds are in a full state, so the germination rate of such seeds is particularly high.

3. To choose the base bed for planting cabbage, you need to choose a neutral soil with high nutrients and good drainage to plant. When sowing, the soil should be broken up and an appropriate amount of farmhouse fertilizer should be added, which can improve the growth quality and nutrient content of cabbage.

4. Divide planting on the soil, sow seeds evenly when sowing, it is necessary to have too dense seeds, and use thin soil to cover them in time after sowing, and you can also sprinkle a layer of broken leaves or broken straw on the soil, which is conducive to the germination of seeds and the maintenance of warmth.

5. When fertilizing, you can choose to use the manure of the decomposed people or use ammonium sulfate to flush the seedlings of the cabbage, and fertilize the cabbage once in the rosette stage, and use nitrogen fertilizer and potassium fertilizer for the fertilizer to supplement, which can promote the healthy growth of cabbage.

Summary. Hello, dear. 1 Choose a good variety of Chinese cabbage:

Kind research and development has been ongoing, the current market to choose from the variety is quite a lot, we in the selection of varieties mainly according to the local climate and environment and market demand to consider, the choice of varieties with high disease resistance is the most. 2. The planting time is general, and there are many farmers who plant Chinese cabbage in autumn.

Hello, dear. 1 choose a good variety of Chinese cabbage: research and development has been carried out, the current market to choose from the variety or brute attack Bu more, we in the selection of varieties mainly according to the local climate and market demand to consider, high disease resistance varieties to choose the most.

2. The planting time is generally rolling, and there are more farmers who plant Chinese cabbage in autumn.

3.Before fertilizing and planting, the land will be ploughed once, and then it is necessary to apply a base fertilizer, the bottom fertilizer must be applied sufficiently, and the fully rotted organic fertilizer and compound fertilizer are matched, and finally the hole is to rake the land flat and rake fine. 4.

Sowing method can be used in the sowing of Chinese cabbage when serving the land, respectively, direct sowing and transplanting, which way to choose which way to combine the harvest time of the previous crops and the preparation of the land, if the farmer's time is relatively sufficient, you can use the direct sowing method, otherwise you have to choose the latter. The difference in timing between the two sowing methods will cause direct seeding to emerge about a week later than transplanting, and if direct seeding is chosen, it is necessary to maintain the moisture and humidity of the soil after the seedlings emerge. And do a good job of treating other weeds near the seedlings, and when the seedlings of Chinese cabbage grow to six true leaves, they should be planted, which should be determined according to the variety of Chinese cabbage they planted.

After transplanting the seedlings, they should be watered once, and then watered once a day in the morning and evening for three days after transplantation to ensure the survival rate of Chinese cabbage seedlings.

5.The field management of Chinese cabbage production process, but also to carry out appropriate top dressing, the time of top dressing and the amount of each time should be determined according to the growth cycle and growth of Chinese cabbage. In principle, top dressing is not required at the seedling stage if the base fertilizer is sufficient.

In the use of fertilizer, try to choose nitrogen fertilizer and phosphorus fertilizer, and water the Chinese cabbage immediately after each top dressing. In addition to the use of fertilizer, watering is also very critical, according to the characteristics of Chinese cabbage, the water during the planting management period Lu Huiqiu is much larger than other vegetables, so according to the growth of Chinese cabbage, it is necessary to increase the amount of watering for Chinese cabbage in time. Here I say a point, that is, when the Chinese cabbage just begins to accompany the seedlings to water early, and be sure to water the ground thoroughly, and then water once in a cycle of three days, if this is not done well, it is very likely that the roots of the Chinese cabbage will be damaged, affecting the future growth of the Chinese cabbage and the final yield.

6.Watering should be stopped about half a month before harvesting, and picking should be completed before the light snow season to prevent frost damage.

1. Soil-based fertilizer. Before planting cabbage, it is necessary to fertilize the soil, which is due to the short growth cycle of cabbage, in the whole growth cycle, there is almost no need to carry out large-quality fertilization, so if you want to make cabbage rise well, it is very important to fertilize the soil before planting, it is recommended that you take farmhouse fertilizer as the base fertilizer, sprinkle it on the soil surface, and then turn the soil shallowly to ensure that the soil and fertilizer are mixed evenly.

2. Land consolidation. After fertilizing the soil in which the bok choy is grown, it is necessary to integrate the land. The root of the cabbage is shallow, the leaf surface is close to the soil layer, and the soil moisture is more likely to affect the cabbage!

In order to facilitate the water control treatment of cabbage in the later stage, before planting, the soil needs to be ditched to ensure that the soil layer does not store water for a long time.

3. Seed selection and sowing. Now planting cabbage, most of them are bought directly in the seed store, this seed does not need to be treated, because it has been processed in advance, and the self-kept cabbage planting, before planting, needs to be awakened by warm water and reeds, soaked in potion and other links.

4. Post-management. Chinese cabbage can be planted all year round, the temperature of the garter is not high, in the later management, do not need to be too controlled, under normal circumstances, cabbage in two or three days after sowing, it will sprout, from germination to maturity, almost no need for watering, only need to ensure that the soil is slightly moist.

5. Precautions. In terms of disease resistance and insect resistance, it is necessary to strictly follow the principle of prevention and treatment in advance! It is recommended to sprinkle a layer of plant ash around the cabbage, which can not only prevent many diseases, but also avoid being eaten by many pests!
