The quality of the Chinese cabbage planted is not high, what method can be used to grow high quality

Generally, after the beginning of autumn, a small piece of land, turn over and level, then sprinkle seeds, raise seedlings, cover with old mats or grass for a day, cabbage seedlings will be unearthed, at this time you can spray water with a sprayer every day, so that the soil is kept moist, and the seedlings grow faster. About half a month or so,Before ordering cabbage, prepare the ground, sprinkle a layer of rotted farmhouse manure on the ground, and then turn the ground to make ridges, sprinkle some compound fertilizer at the bottom of the ridge as base fertilizer when the ridge is formed, and wait for sowing with a solid ridge surface. When planting, a narrow furrow is drawn on the ridge surface.

Fertile, soft sandy soils rich in organic matter and neutral or acidic soils that are clayey and not compactedBefore planting, it is necessary to carry out deep ploughing and ploughing of surface weeds, eradicate the source of disease breeding, and try to avoid heavy crop plots. 1,87 spring 34, cultivated by Qingdao Agricultural Science Institute of Shandong Province, the plant is slightly erect, single bead kilogram, growth period of 60 days, mu yield of 5000 kg. 2. Chunlu No. 1, cultivated by Tianjin Kerun Vegetable Research Institute, has a growth period of 60 days and a yield of 5,000 kg per mu.

Soil: Choose neutral soil with high nutrients and good drainage; Sowing seeds should be evenly sown on the soil and covered with thin soil; Fertilization uses nitrogen fertilizer and potassium fertilizer for auxiliary fertilization, and follows the principle of thin fertilizer and frequent application. If you want to know how to grow cabbage, you must first know when it was planted. To plant Chinese cabbage, you must first apply plantar fertilizer, and it is best to use rotted and vomiting farmhouse organic fertilizer with compound fertilizer.

Generally, the amount of fertilizer can be determined according to the fertility of the soil, and it is recommended that about 3,000 kilograms of organic fertilizer per mu of rotted and vomiting farmhouse fertilizer be applied with about 40-50 kilograms of compound fertilizer.

Seeding method:When sowing, three methods of strip sowing, hole sowing and machine sowing can be used, and the appropriate sowing method can be selected for sowing, and the dosage per mu is generally about kilograms. The field planting beads are 30 cm to 40 cm apart, and 3,000 to 4,000 plants per mu are planted.

Before transplanting, prepare the land, sprinkle compound fertilizer and farmhouse fertilizer, ridge formation, you can raise wide ridges, and plant two rows of cabbage. You can also set up narrow ridges and plant a row of cabbage, and the ridges play the role of waterproofing and drainage. After planting cabbage seedlings, water, if the weather is fine, it is best to cover for two days, cabbage is easy to survive.

Selecting disease-resistant, high-yielding, and high-quality varieties suitable for local climatic conditions is the prerequisite for high yield and high quality. Cabbage has late-maturing varieties, medium-ripening varieties and early-maturing varieties, which are flexibly arranged according to climatic conditions and stubble, but must be selected according to the local pests and diseases. When planting Chinese cabbage in autumn, the temperature is high, the light is too mild, and the soil is easy to lose water.

1. Key points of cultivation technology.

First of all, it should be treated in advance, many seeds will have some germs, stir the seeds with Fumei double wettable powder, or stir with some promethine wettable powder. Stirring the seeds will directly reduce the effects of black spot.

The second is to pay attention to the regulation of temperature and humidity, the humidity in the field is large, it is easy to be infected with some diseases, should be reasonable ventilation and watering, after the rain has stagnant water to be discharged in time.

The third is drug control, adhere to the principle of prevention is greater than cure to prevent pests and diseases, Chinese cabbage should be sprayed as soon as possible in the early stage of prevention.

The fourth is fertilization, Chinese cabbage adheres to the principle of base fertilizer as the main fertilizer and fertilization as the supplement. The base fertilizer is mainly organic fertilizer, and the appropriate amount of chemical fertilizer is applied. During the growth period, fertilizer should be applied according to the growth of Chinese cabbage, Chinese cabbage growth is vigorous, the application of chemical fertilizer should be controlled, under normal circumstances, you can add some more phosphate fertilizer and potassium fertilizer in an appropriate amount.

2. Ways to improve the quality of Chinese cabbage:

Reasonable fertilization and scientific fertilizer and water management are the most basic foundations for improving the quality of Chinese cabbage. Only in this way can the cabbage itself grow strongly, which is the basis for the formation of good quality. In addition, in fertilization, we should pay special attention to the use of a small amount of chemical fertilizer, and apply more organic fertilizer, especially base fertilizer, which must be based on organic fertilizer.

In real life, many people like to eat Chinese cabbage, and the Chinese cabbage they want to grow is of high quality, one is to control the growth environment of Chinese cabbage, and the other is to control the nutrient intake of Chinese cabbage.

You can choose high-quality seeds when planting, choose fertile soil, and water it more often, so that the Chinese cabbage will be very high-quality.

Use a strict schedule to grow cabbage, and control the soil and air humidity, as well as the amount of water, so that you can grow high-quality cabbage.

The first thing is to ensure the temperature and humidity of this planting base, and there is also to water and fertilize regularly, and you can also spray more pesticides.

Fertilization, Chinese cabbage can grow well and grow big when it gets enough nutrients.

During the balling period, water-soluble fertilizer or urea can be applied with water when watering, and it can be applied once every 10 days, and it can be applied 2-3 ratios, and after the temperature drops, it can be supplemented by spraying potassium dihydrogen phosphate. In the later stage, the root system of cabbage is aging, and the only way to quickly replenish nutrients is to spray foliar fertilizer. Chinese cabbage is grown in spring, summer and autumn, and autumn Chinese cabbage is the best quality.

Before planting Chinese cabbage, it is necessary to sprinkle sufficient organic fertilizer in the ground, of course, mixed with a certain dose of compound fertilizer, and then carry out ridge watering and water the soil to prepare for sowing.

To choose the quality of the variety, you must go to a regular place to buy seeds, in order to avoid the lack of seedlings or seedlings refuse to grow, etc., so that the yield of the Chinese cabbage you grow can be reduced. In terms of seed selection, it is easy to grow in 85-90 days (such as Yiheqiu varieties, Qingbai, Northeast dwarf cabbage, etc.), and it can be harvested in November when planted on dog days according to the time calculation, and it is easy to store at an excellent time.

Nowadays, there are many varieties of Chinese cabbage, people do not know how to choose a suitable variety when planting Chinese cabbage, in fact, when choosing Chinese cabbage varieties, we should choose suitable Chinese cabbage varieties according to the planting time, local climate characteristics, etc. The middle rosette stage is a time when the growth period is rapid and the root system extends extensively. Should be topdressed, according to the proportion of 15 20 kg of urea per mu, and then with a certain proportion of potassium fertilizer and phosphorus.

Chinese cabbage is a vegetable that needs to be supplemented with calcium, we can apply fertilizer with calcium, which can reduce the decay during the transportation process and placement of Chinese cabbage, and this can also improve the quality of Chinese cabbage, so that Chinese cabbage is resistant to storage and not easy to rot leaves to improve yield and quality. After rain or irrigation, the surface of the soil is easy to dry, which can reduce the occurrence of soft rot. At the same time, high ridges allow air circulation in the lower part of the cabbage plant, reduce air humidity, and thus reduce the occurrence of downy mildew. Then in the winter, you can harvest the big cabbage.

Choose permeable, fertile and loose soil, the second seedling should wait until the seedlings appear four true leaves, we should adjust the spacing of Chinese cabbage, and the spacing of each Chinese cabbage should be kept at about half a meter, and there is enough space to grow.

In the process of cabbage growth and development, the demand for nitrogen fertilizer, phosphate fertilizer and potassium fertilizer is relatively large, of which the demand for nitrogen fertilizer occupies the first, nitrogen can promote leaf growth and chlorophyll synthesis, if the growing cabbage lacks nitrogen fertilizer, the whole plant leaf color will become lighter, and the plant grows slowly, so nitrogen fertilizer must be sufficient, improve the photosynthetic rate, promote growth, and increase yield.

Sufficient basal fertilizer: Chinese cabbage needs a lot of fertilizer during the growth period, sufficient basal fertilizer is the fundamental guarantee of high yield and excellent income in the later stage, and fertilization should adhere to the principle of organic fertilizer and chemical fertilizer. The base fertilizer can be applied to 4000-5000 kg of rotting farmhouse fertilizer + 15-20 kg of potassium chloride + 20-25 kg of diammonium phosphate per mu, or 3000-4000 kg of decaying farmhouse fertilizer + 40-45 kg (16-6-18) potassium sulfate compound fertilizer + about 1 kg of borax, and the specific fertilizer amount is flexibly mastered according to the actual situation of the plot.

You can water the Chinese cabbage more, fertilize it more, and spray it with insecticidal pesticides in advance, so that its yield will be very high.

How to plant Chinese cabbage to ensure good effect and high yield?

The planting method of Chinese cabbage is as follows: 1 plot: Before planting Chinese cabbage, you need to choose a soft and fertile, well-drained, convenient drainage and irrigation plot, and deeply fertilize the soil, with a depth of 20 cm, and then put the soil in the sun for sun exposure, so as not to leave insect eggs in the soil and affect the normal growth of the plant.

2. Sowing and planting: select Chinese cabbage seeds with full, healthy and non-damaged particles, and then take the way of live broadcasting, evenly spread the seeds on the soil surface, and cover a layer of fine soil, and at the same time water a permeable water, which is conducive to the germination of seeds, and ensure that the row spacing of 50 cm and the plant spacing of 30 cm should be ensured when sowing. 3. Carry out inter-seedling management

When the cabbage is in the seedling, it is necessary to water regularly to keep the soil moist, but there can be no water accumulation, and the root system of the plant is not developed at this time, and the absorption capacity of fertilizer is weak, so it is necessary to reduce the amount of fertilizer, and wait for the Chinese cabbage to enter the growth period, and then spray calcium chloride solution or calcium nitrate solution. Proper cultivation and standardized management will increase yields.

If you want to grow high-quality and high-yield Chinese cabbage, how do you need to plant it? In fact, growing high-quality, high-yielding bok choy is not easy. Lao Pang is a grower in Ningling County, Shangqiu.

Every year he planted several earthen cups. First, water the soil. When kale emerges, it needs a certain amount of soil moisture to ensure the growth of kale.

The kale he grows not only has a high income, but also has a high-quality soil for growing kale. The root system of Chinese cabbage is very shallow, so soil with high water and fertilizer retention should be chosen. Chinese cabbage seeds are very small.

In order to ensure the emergence rate of Damengxiang cabbage, the soil must be flat and the soil layer is loose to ensure the planting time. Because the transition period between hot and cold is most conducive to the growth of kale balls. After the cabbage is planted, if the depth is sufficient and the soil moisture is good, the mud can be seen within three days.

When the loaches grow to their true leaves, early pruning must be taken, not whether the camp should be timely, and later ones will lead to unbridled pest control activities during the sowing phase.

This is to avoid the selection of pests. First of all, we must choose good varieties according to the climatic conditions of the region, and we must also consider that white fertilization is mainly organic fertilizer, supplemented by chemical fertilizer; With basal fertilizer as the mainstay, top dressing as a supplement, and sufficient basal fertilizer due to the need for fertilization, many farmers will encounter two problems, that is, the implementation of special damage to Chinese cabbage per mu on low fertility soil. There was an obvious slow phenomenon of ion seeding in the jointing and transplanting of seedlings, which would damage the root system of Chinese cabbage to a greater or lesser extent during the transplanting process, and affect the normal growth rate of Chinese cabbage.

Autumn-sown cabbage is mostly a mature variety, with compact plant shape and slow growth and development. At the same time, due to serious pests and diseases, high seed shortage rate, near reasonable planting is an important factor to achieve high yield, the general row spacing is 44 50cm, row spacing 40, Chinese cabbage roots should be controlled in time, therefore, the soil with high water and fertilizer retention rate should be selected. Chinese cabbage seeds are small.

In order to ensure the seedling rate of Chinese cabbage, the soil needs to be flat and loose so that the Chinese cabbage roots can absorb better nutrients, and it is treated separately to remove infected plants.

Attention needs to be paid to planting, fertilization, pests and diseases, weather and watering. Because these aspects are very important for planting vegetables, and will also affect the yield of vegetables, we must pay attention to these aspects when planting vegetables.

When planting vegetables, you need to pay attention to reasonable watering and fertilization, and when the temperature is relatively high, you should water it many times, and you should water the soil thoroughly every time you water, and you should also pay attention to preventing pests and diseases.

It is necessary to pay attention to the condition of the soil, pay attention to the selection of varieties, pay attention to the temperature, pay attention to the drainage, pay attention to the condition of nutrients, and the soil needs to be disinfected.

For summer sowing of Chinese cabbage, it is necessary to select seeds that are heat-resistant, early-maturing, short-growing, commercially good, and disease-resistant, and Chinese cabbage has stricter requirements for water and soil. Therefore, it is suitable for planting in soft and fertile soil, convenient areas for drainage and irrigation. It is recommended to plant high ridges, which not only benefit drainage and irrigation, but also improve field permeability and reduce the occurrence of diseases.

Under the condition of sufficient basal fertilizer in the field, there is no need for top dressing before pelleting cabbage. If the field is not good, not only should enough nitrogen fertilizer be applied, but potassium fertilizer should also be increased. Urea and compound fertilizer can be mixed and watered after top dressing, which can meet the characteristics of large water demand during the granulation period of Chinese cabbage and promote the rapid absorption and utilization of nutrients.

At the nodulation stage, sufficient water can also prevent the occurrence of dry heartburn in cabbage, but the field should not be watered, and try not to irrigate with large water to prevent the occurrence of diseases. Watering should be reduced or stopped before harvest to ensure quality and shelf resistance; In case of rain, drain water in time.

The sowing of Chinese cabbage in summer is generally carried out by direct seeding, rather than by seedling raising. The sowing amount is about 200 grams per mu, the planting density requires a row spacing of 40-50 cm, a plant spacing of 30-40 cm, and about 3000-4000 plants per mu.

In the summer Chinese cabbage growth period, it is necessary to prevent bad weather in the summer Chinese cabbage growth period with high temperature, rain or little rain, so after the rainstorm, it is necessary to drain the water in time, the soil should fix the root system, and at the same time, it should be spray dried with potassium dihydrogen phosphate solution to promote the growth of leaves, and water and dry in time.

Chinese cabbage has shallow root group and weak absorption capacity, so fertilizer water should continue to be supplemented during the growth period. Timely fertilization after planting to promote the recovery and growth of seedlings; Secondly, the concentration and amount of top dressing should increase with the growth of the cabbage individual. As for the fertilization method, cycle, and dosage, it depends on the weather, seedling conditions, soil, etc.

Watering is combined with top dressing. There can be no shortage of water for 3 5 days after planting, especially in summer and early autumn, and it must be watered every morning and evening for 3 4 consecutive days after planting.

The cultivation of Chinese cabbage should be based on organic fertilizer, chemical fertilizer should be applied appropriately during the growth period, and foliar topdressing should be combined with sprinkler irrigation. For example, sugar alcohol chelated calcium foliar fertilizer is a fertilizer with a good calcium supplement effect for Chinese cabbage.
