Chinese cabbage is a common leafy vegetable, what skills do you have to master to make the core firm

First of all, scientific top dressing, especially nitrogen; second, reasonable watering, Chinese cabbage has a large water demand; the third is to spray foliar fertilizer, which is sprayed every 10 days; Fourth, control pests and diseases.

It is necessary to master the technology of watering, but also to master the technology of equipment, to pay attention to water and fertilizer management, to pay attention to the prevention of diseases, and also to pay attention to the mode of management.

To remove pests and diseases in advance, to avoid hot weather, to apply enough organic fertilizer, and you can also use well-rotted farm fertilizer. It is necessary to water in time, and there must be no shortage of water.

It is necessary to prevent pests and diseases in time, and pay attention to the planting time, avoid hurting the roots in the process of transplanting, and also timely top dressing. It can be prompted in time.

You need to choose the right variety, pay attention to fertilization when planting, and wait for the growth to be almost the same, and tie the Chinese cabbage with a rope, so that it can grow more firmly.

First of all, we should pay attention to the timely watering and fertilization of the bridge, and we should also prescribe the right medicine in time to supplement the nutrient sensitive hail solution, do a good job of loosening the soil, and should also spray pesticides in time, and do a good job of cultivating and preventing insect pests.

You can spray more wet rice vinegar when planting cabbage seeds, which can protect the cabbage and not be easily attacked by pests, thereby increasing the yield.

Spray rice vinegar. From the Chinese cabbage seedlings to the first annihilation of the heart, 50 kg of 1% rice vinegar or acetic acid aqueous solution was sprayed per mu each time, and 4-5 times were sprayed in a row, with an interval of 10 days each time. According to the test, spraying vinegar with Chinese cabbage can increase the yield.

The early stage of Chinese cabbage balling is the high-efficiency fertilization period, which has a decisive effect on the yield, and the heavy topdressing is more important than the seedling stage, rosette stage and mid-balling stage. Foliar spraying of urea and potassium dihydrogen phosphate mixed solution during the growth period, as well as spraying titanium-containing micro-fertilizer, can improve the net rate of Chinese cabbage and increase the commodity value.

Chinese cabbage is an important leafy vegetable. The yield of the big white menu is very high, and the requirements for fertilizer are relatively high. The ratio of nitrogen, phosphorus and potassium is 1.

Therefore, Chinese cabbage, like other leafy vegetables, is of great significance in promoting the formation of hypertrophic green leaves and increasing photosynthetic rate during the vegetative growth period.

There is not much fertilization regularity, a little fertilization and watering is carried out when the cabbage grows, and at the same time, it is also necessary to try it once when it is medium and large, and water some water, but each fertilization is not too much.

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.

Cabbage is our common vegetable, do you know how it's grown? In general, there are many methods of drilling. However, there are differences between these two methods of large-scale cultivation.

Chinese cabbage is the most common vegetable in our lives, especially in the northern regions. Each Gosta family grows some vegetables that can be eaten fresh or made into pickled vegetables or pickled vegetables. Chinese cabbage has excellent flavor and rich nutrition, and is generally cultivated by sowing and transplanting, which not only has a high survival rate, slow sowing, but also a fast and high yield.

For soil preparation and fertilization, the soil for planting must first be chosen. It is recommended to use mainly loose, fertile sandy soils* or soils rich in organic matter*. Plants grown in the former crop should not have cruciferous vegetables.

Chinese cabbage is usually planted directly one week before sowing, watered after covering the soil, thinning when the leaves grow, and top dressing and irrigation are also carried out during the growth period.

Chinese cabbage should be planted on higher seed plots and close to water sources for easy irrigation and drainage. The mass must be integrated into small pellets, after which the flat plant is first surrounded and sown with water. Direct EM radio is primarily an experimental type of broadcasting, supplemented by on-demand broadcasting.

In the case that the previous crop is not currently empty, mudas can also be used for transplanting. Either way, kale is planted between July and August each year. The temperature in midsummer is suitable for growing Chinese cabbage.

Long-term sunlight allows Chinese cabbage to fully absorb light, accumulate nutrients, and grow healthy and delicious kale, and many people like to grow vegetables at home. In fact, Chinese cabbage is a kind of vegetable native to China, also known as "Chinese cabbage head", "Chinese cabbage head wrapping", "yellow bud white", "no matter what method is used, the amount of seeds directly sown is about 200 grams per mu. Education is not difficult.

What are the technical points of organic Chinese cabbage planting? The first and most important step in planting organic Chinese cabbage is to choose a pollution-free planting base with a beautiful ecological environment. The planting base should be kept away from factories, traffic arteries and other heavily polluted places.

Ensure that the air quality, water source, etc. are in line with the standards of organic farming. And the pre-crop crops of the soil should not be cruciferous crops such as cabbage.

If kale is grown continuously, it is easy to get sick, and for crop rotation, it is best to rotate crops and plants. If it's just a vegetable patch, it can't be compared to other cruciferous vegetables. The first harvest must be beans, peppers, cucumbers and other vegetables, and the soil in which the Chinese cabbage is grown must be deeply cultivated for 20 27 cm in Contra for 10 15 days, and then the soil is broken and leveled to form a border of meters wide, or a narrow and high boundary of one meter.

And surround the vala by more than 27 cm, so that the ditches are connected.

4-5 grains per hole, covered with an inch of soil, covered with film after proper watering, there are many varieties of Chinese cabbage, which can be divided into three basic ecological types: straight pipe type, round head type, and egg ring type. The corresponding growth period is divided into early, middle and late three stages, you should also understand this when choosing autumn cabbage, many farmers in the north want to plant cabbage, and then plant backward wheat, the key is to combine your planting plan. In mid-July, there are two ways:

Sow broccoli and sow holes.

If the soil is dry, it is necessary to sow seeds in water. First open a deep shallow ditch, water along the ditch, soak the water to evenly root the seeds, and use it for vara; When sowing holes, shallow holes with a spacing of 40-50cm and a depth of 40-50cm should be watered according to the different holes. After water infiltration, 5-6 seeds must be sown in the cada hole and covered with thick soil.

Only the right varieties will have a higher yield, and it is generally recommended to choose varieties with strong disease resistance, and the sowing time is around July of the second year, and the sowing method is mainly hole sowing or sowing.

Chinese cabbage is a vegetable that we often eat, it contains a variety of essential trace elements, and eating more will have many benefits for the body.

Basically every household in the countryside will grow Chinese cabbage, but there may be a situation in the planting process, so what is going on? In fact, the main reason is caused by the following four aspects, let me tell you about it!

Chinese cabbage is not hearty mainly caused by the following four aspects:

1. Improper use of fertilizers.

1. Some growers often apply nitrogen fertilizer in order to grow rapidly when planting cabbage.

In fact, this is wrong, experience shows that the use of excessive nitrogen fertilizer not only causes cabbage to grow and has a bad heart, but also causes the finished cabbage to taste "bitter", which affects the economic value of cabbage and causes losses!

2. To solve this problem, it is necessary to achieve a balanced fertilization, appropriately supplement phosphorus and potassium fertilizers, and reduce the use of nitrogen fertilizers.

Phosphorus and potassium fertilizer supplementation, in addition to root topdressing, can also be carried out by spraying foliar fertilizers such as potassium dihydrogen phosphate.

Foliar sprays will absorb the crop quickly and have a quick effect.

2. Planting density.

1. If the planting density is too large, the cabbage leaves can not carry out photosynthesis well, and due to the large density of poor oranges, it is easy to "defertilize" the phenomenon, resulting in insufficient plant nutrients, so that the core is not firm or not covered.

2. Therefore, when we transplant cabbage seedlings, we should plant reasonably densely, and the spacing between the virtual head group is generally 25-35 cm, which is also slightly different due to different varieties.

The row spacing is 60-70 cm.

3. Stagnant water in the field.

1. The early growth of cabbage is in the period of high temperature and rain, it is necessary to pay attention to the fact that there can be no stagnant water in the field, which will not only cause poor heart, but also be easily infected with various diseases, such as root rot, stem rot, etc., so it is necessary to keep the field drained smoothly.

2. Cabbage is a water-loving crop, and it should be watered in a timely manner during the drought period, especially in the heart-wrapping period.

The centering period is the period when the demand for water and fertilizer is the largest.

The principle of watering is to ensure that the field is dry and wet.

Fourth, pests and diseases cause bad heart.

Common diseases of cabbage mainly include root rot, stem rot, downy mildew, etc., which can be prevented and controlled by spraying 3500 times of agricultural streptomycin or 3000 times of 50% carbendazim wettable powder.

The main insect pests are cabbage insects, aphids, etc., which can be sprayed with water according to the instructions with chlorbide or cypermethrin

Spray every 5-7 days, 2-3 times in a row.

If you find that the cabbage you planted has a bad heart, or there is no heart, most of it is caused by the above four aspects, and you still need to take measures in time! I hope this article can help everyone!

That's all for the reason why Chinese cabbage is not heartfelt, welcome to read other agricultural content on cucumber network.

Vegetables and fruits have always been inseparable from the daily table of ordinary people, and Chinese cabbage is a very common one, the price is not too high and the demand is large, especially in North China, the total planting area is very broad. The wrapping link is one of the important links in determining the production volume and product quality of Chinese cabbage. How to solve it?

Sake :1Planted too late.

In the case of too late sowing date, the growth period of cabbage is short, the effective accumulated temperature is insufficient, and it is very easy to have the situation that the cabbage is difficult to wrap and the core is not hard.

2.Fertilizer is unreasonable.

The topdressing management method in the core stage is very important, and the early stage of the core should also pay attention to increasing chemical fertilizers, and it is not necessary to increase chemical fertilizers until the core stage. Special attention should be paid to the balance of fertilizer, and basal fertilizer and phosphorus and potassium fertilizer must have a certain proportion.

3.Watering is not reasonable.

During the growth period of Chinese cabbage, it encounters long-term continuous rain, frequent rainfall, excessive humidity in the field environment, and the drainage pipe is not immediate, or in the cabbage rosette stage. If sufficient power supply is not ensured during the core wrapping period, the water supply is uneven, sometimes more and sometimes less, and sometimes dry and sometimes wet will also cause the cabbage to wrap slowly and the core is not real.

4.Pest control is not reasonable.

During the growth and development period of cabbage, diseases are also easy to occur, which endanger the growth and development of cabbage at a certain level, and will also cause cabbage to not be heartfelt.

1.Choose the type of cabbage that is easy to wrap.

2.Autumn Chinese cabbage planting should not be too late, according to the local time planting at the appropriate time.

3.Watering effectively. In the rosette period of cabbage. Wrapping phase. During the balling period, scientific research and watering are ensured to ensure sufficient power supply, uniform water, and can not be dry and wet, and the soil can be kept moist.

4.Spray leaf fertilizer to push the core.

5.Carry out the management method of bunched leaves for cabbage. First, layer the scattered cabbage leaves.

Neatly plough and plough it, wrap up the leaf balls, clamp them with your legs, and then use sweet potato vines. Soft straw such as rice stalks bind the upper end of the leaf balls, which is beneficial to the cabbage to wrap the heart. Do not water the cabbage a few days before the actual operation of binding the cabbage, and the amplitude should be moderate at the time of binding, and do not tie it too tightly.
