What is the best fertilizer to use for growing Chinese cabbage, and what kind of fertilizer is good

Planting Chinese cabbage with the best farm fertilizer, the highest quality of vegetables, really help you look forward to it, <>

Fertilization during the planting period of cabbage. Before land preparation, it is necessary to apply foot fertilizer, and the amount of fertilizer can be determined according to the soil fertility of the planting area. It is recommended to apply 2,000 kg of well-rotted organic fertilizer per mu, and then apply 25 kg of diammonium hydrogen phosphate, 25 kg of potassium fertilizer or 50 kg of compound fertilizer.

During the cabbage seedling squatting stage, 20 kg of urea or 50 kg of ammonium sulfate should be applied in about ten to 20 days, and then watered.

Chinese cabbage should pay more attention to the application of core fertilizer. In the early stage of cabbage wrapping, that is, from the end of September to the beginning of October, 25 kg of urea needs to be applied to ensure that the cabbage has enough nutrients. The fertilization ratio of Chinese cabbage throughout the growing period is 1:

3:4:2, that is, the seedling stage is 1, the rosette stage is 3, the pre-ball stage is 4, and the middle stage is 2.

When topdressing, the amount of fertilizer can be reduced according to this standard, and it can be carried out together with watering.

Because cabbage is a shallow root vegetable, the ability to absorb water and fertilizer is relatively weak, so during the growth period, it is necessary to continuously supply fertilizer and water, and apply fast-acting nitrogen fertilizer many times, which can effectively promote the growth of cabbage, improve the yield of cabbage, and try not to use chlorine-containing fertilizer, such as topdressing chlorine-containing fertilizer, cabbage cellulose increases, and the taste is rough to eat, which seriously affects the quality of urea and ammonium bicarbonate Although it can increase the yield of cabbage, it needs to be mastered in terms of dosage, and the amount can not be used too much, especially in the later stage of growth, if the nitrogen fertilizer is excessive, Not only will the cabbage be poor, but also the cabbage leaves have a large moisture, which affects the taste, and is easy to rot when preserved, and is prone to insect pests in the later stage of growth. If cabbage is not fully fermented farmhouse fertilizer, it is easy to incur pests and diseases, resulting in underground pests, rotten roots, soft rot, etc., farmhouse fertilizer must be fermented and rotted well, otherwise not only can not increase yield, but also lead to the occurrence of various pests and diseases.

What kind of fertilizer is good for growing Chinese cabbage?

Apply sufficient basal fertilizer. Chinese cabbage has a long growth period, and needs high-quality organic fertilizer with long fertilizer effect as base fertilizer, generally 2500-3500 kg of rotting farmhouse fertilizer + 15 kg of urea + 15 kg of diammonium phosphate + 15 kg of potassium sulfate per mu.

Before ploughing the land, 60% of the base fertilizer is sprinkled in the ground, turned deep into the soil, and then the remaining base fertilizer is sprinkled on the ground before raking, raked into the shallow soil, and then ridged.

Skillful application of seedling fertilizer. After the Chinese cabbage leaves grow, when the taproot grows to about 10 cm high, the ability of seedlings to absorb nutrients is gradually enhanced, and 5-7 kg of urea can be applied as seedling fertilizer after the first seedling to promote the growth of seedlings.

When fertilizing, small seedlings and weak seedlings should be applied to promote the formation of strong seedlings.

Reasonable top dressing.

Planting Chinese cabbage with foot manure (farmhouse fertilizer and straw fertilizer), top dressing is best rotted cake fertilizer, so that the cabbage produced tastes very good (also depends on the variety). Cabbage is best planted with organic fertilizer, but in order to achieve the purpose of nutritional balance, it also needs to be combined with compound fertilizer, potassium sulfate, superphosphate and other fertilizers. Planting Chinese cabbage should have enough organic base fertilizer, Chinese cabbage top dressing should be based on the principle of "light before and heavy after", top dressing is best rotten cake fertilizer, so that the production of cabbage taste very good and also depends on what variety.

Now animal manure, mainly chicken manure, cow manure, deer manure, pig manure, these manure pile together, it will be naturally fermented, it doesn't matter whether the fermentation is good or bad, because you put these animal manure on the land, these manure is also fermented at any time, and the long-term life of animal manure can be extended to next year, and the soil structure of the land can be soft, and it will always be the best fertilizer for grain and vegetables!

So if you want to grow cabbage, go to chicken farms, cattle farms, deer farms, pig farms and buy fertilizer for these animals! Chinese cabbage is mainly top-applied with nitrogen fertilizer, which can be applied with high nitrogen flush fertilization. In the process of cabbage management, to prevent the occurrence of soft rot, fungicides that kill bacterial diseases, such as thiohedrone or thiametone, can be sprayed.

It is also necessary to pay attention to the supplement of calcium fertilizer and the prevention and control of hollowness, and you can use the Washeng calcium of Bayer in Germany or the Yingfeng calcium of Yinghui. Of course, these products work better when combined with fast-acting, high-nitrogen, water-based foliar fertilizers.

When ploughing the ground, the bottom fertilizer is applied enough (general organic fertilizer, depending on the land situation, and then see how much, the fertility of the normal perennial rotation of the land is poor, and the fertility is more to give a point) after the fixed value of the compound fertilizer begins to wrap the heart, and then come to the compound fertilizer. Chinese cabbage is one of the sparse vegetables commonly grown in rural areas, and it also brings unique economic benefits to farmers. Management is also very important, Chinese cabbage has a well-developed root system, so Chinese cabbage has a strong ability to absorb nutrients and water.

It is best not to plant in rotation on the same plot to prevent bacterial infection.

The planting of Chinese cabbage base fertilizer is applied at one time, and it is advisable to apply 1000 kg of rotting farmhouse fertilizer per mu: 5 kg of biological potassium fertilizer: 50 kg of potassium sulfate compound fertilizer.

Control nitrogen, phosphorus and potassium, and prevent and control Chinese cabbage diseases: downy mildew, black spot, white spot, white rust, brown rot, root swelling, black rot, soft rot, virus disease, spraying prevention. It is also necessary to strengthen fertilizer and water management.

It is better to use animal manure as fertilizer, because animal manure is a natural fertilizer and is very valuable.

Isofast-acting fertilizer. If the base fertilizer is insufficient or no base fertilizer is applied before planting, 1000-1500 kg of urea can be applied per mu. Fertilization at the seedling stage should pay attention to the focus on weak seedlings and small seedlings to promote their growth into strong seedlings.

3. Grow a fertilizer.

The rosette leaves grown at the rosette stage of cabbage can provide nutrients for photosynthesis when cabbage sets balls, which is closely related to the yield of cabbage. The amount of fertilizer required by cabbage in the rosette period began to increase, and the top dressing in the cabbage rosette period was called hair fertilizer. The application time of plant fertilizer is when a small amount of cabbage begins to clump trees, and the application rate is 800-1500 kg per mu of farmhouse fertilizer, 50-100 kg per mu of plant ash, or 10-15 kg of ammonium nitrate per mu, and 7-10 kg of phosphorus and potassium fertilizer per mu.

Foliar fertilizer can also be sprayed appropriately at the rosette stage of cabbage, spraying potassium dihydrogen phosphate aqueous solution + borax solution + urea solution aqueous solution 3-4 times on cabbage leaves, spraying once every 7-10 days. Spraying is best chosen in the evening when it is clear and windless.

Fourth, bulking fertilizer.

The balling stage is the period when cabbage needs the most fertilizer, accounting for about 70% of the total fertilizer requirement in the growth cycle of cabbage. The first application time of balling fertilizer is at the early stage of cabbage core, and 10-15 kg of urea is applied per mu to promote the rapid growth of cabbage. The second and third top dressing was carried out in the middle stage of balling, and 10 kg of urea was applied per mu to increase the growth of cabbage heart leaves.

At the same time, 10 kg of potassium fertilizer can be applied per mu during the balling period.

It's good to use compound fertilizer, mainly because this fertilizer can also make Chinese cabbage grow better and can supplement some of the nutrients needed.

Nitrogen fertilizer, the growth of Chinese cabbage is inseparable from nitrogen, which will increase the yield.

Sufficient basal fertilizer is the basis for high yield of Chinese cabbage. The base fertilizer is applied with 2000 2500 kg of rotting farmhouse manure per mu, 4 5 kg of urea, 11 17 kg of diammonium phosphate, 6 7 kg of potassium sulfate, and 20 kg of calcium nitrate per mu of calcium-deficient soil.

Mainly chicken manure, cow manure, deer manure, pig manure, these manure pile together, it will be naturally fermented, it doesn't matter if the fermentation is good or bad, because you apply these animal manure to the land, these manure is also fermented at any time, and the base fertilizer should be sufficient. Applying sufficient basal fertilizer is the basis of high yield of cabbage, generally 4000-5000 kg of fully decomposed farmhouse fertilizer per mu, and adding 15-20 kg of superphosphate and 15 kg of potassium fertilizer. Based on basal fertilizer, combined with basal fertilizer and top dressing, top dressing should be based on nitrogen, nitrogen, phosphorus and potassium should be reasonably matched, and trace elements should be appropriately supplemented.

According to the plan, about 8,000 kilograms of fresh cabbage per acre of land is used as a basis, 3,000 kilograms of organic fees and 30-40 kilograms of nitrogen fertilizer are required.

That situation has appeared, which proves that vegetables also have its value, the people's demand for it is also quite indispensable, the world is developed today, vegetables are still quite important to people's needs, friends can not ignore the needs of vegetables for people, how important it is. The results showed that under the same conditions of nitrogen and phosphorus fertilizer, potassium fertilizer (50% potassium sulfate) was applied to Chinese cabbage by 18 kg, which was 2866 kg per mu compared with the control, and the yield increase rate was as high as 159 kg per kg of potassium sulfate.

After the live broadcast, 2,000 catties of manure need to be applied to each acre, and they should be watered once in the morning and evening, and the soil should be kept moist every day, and the seedlings can emerge in about three or four days. When transplanting seedlings, less than 2,000 plants per acre, with a row spacing of about 30 to 50 centimeters, and choose to carry out it in the evening on a cloudy day or a sunny day.

Chinese cabbage is better to apply calcium chloride solution or calcium nitrate solution, or urea, or potassium dihydrogen phosphate solution.

Hello, about your question, I think that according to the soil nutrient status, when fertilizing Chinese cabbage, it is necessary to achieve the dual goals of high yield and high quality, and meet the needs of Chinese cabbage with scientific and reasonable inputs.

1.Nitrogen fertilizer should be appropriate: based on base fertilizer, combined with base fertilizer and top dressing, top dressing should be based on nitrogen, nitrogen, phosphorus, potassium reasonable matching, appropriate supplementation of trace elements, according to the plan per mu of fresh vegetables about 8000 kg of Chinese cabbage as a basis, need to apply 3000 kg of organic fertilizer, 30-40 kg of nitrogen fertilizer, 8-12 kg of phosphate fertilizer, 28-40 kg of potassium fertilizer.

It is necessary to remember that organic fertilizer and phosphate fertilizer are used as base fertilizer at one time, about 30% nitrogen fertilizer and potassium fertilizer are used as base fertilizer, and the remaining 70% nitrogen fertilizer and potassium fertilizer are chased in one time at the rosette stage and before the centering. Excessive nitrogen fertilizer is not only the outer leaf hypertrophy of Chinese cabbage, poor heart, low yield and quality, and the leaf water content is large, which is not tolerant to storage after harvesting, and is easy to rot and suffer from pests and diseases in the later stage of growth.

2.Increase the application ratio of phosphorus and potassium: In the production process of Chinese cabbage, it is necessary to apply an appropriate amount of potassium fertilizer, which is beneficial to the core and disease resistance of Chinese cabbage.

Attention should be paid to the application of potassium fertilizer in the early stage of topdressing, especially in the core stage, if phosphorus and potassium fertilizer are insufficient, it will not be easy to ball. Even if the ball is formed, the ball will not be firm, which will reduce the commerciality of the product. As for the amount of potassium fertilizer used, generally speaking, for every 2,000 catties of Chinese cabbage produced, nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer are probably needed, and their proportions are.

3.Calcium supplementation: Calcium is also one of the nutrients that Chinese cabbage needs to supplement, if there is a lack of calcium and too much nitrogen fertilizer, it is easy to cause Chinese cabbage "dry heartburn".

Controlling nitrogen fertilizer and supplementing calcium nutrition is an important technology to prevent "dry heartburn" disease of Chinese cabbage. In addition to applying calcium-containing fertilizers on the soil, you can also take the method of foliar supplementation, spraying calcium nitrate, or spraying calcium glycosol and calcium amino acids, with an interval of one week to about ten days at intervals. Hope it helps.

Fertilization must choose a fertilizer mixed with organic fertilizer and phosphate fertilizer, which can make the production of Chinese cabbage better and can also improve the yield of Chinese cabbage.

Before planting Chinese cabbage, you must eat a good basic fertilizer, so that the Chinese cabbage can thrive in the future. After the Chinese cabbage rises to a certain level, you can apply basic fertilizer, which will make the Chinese cabbage better.

It is better to use compound fertilizer, because it is rich in nutrients, including charcoal soil, coconut peat soil, humus soil, etc., which can well promote the growth of plant root tips, and you can also use plant ash as fertilizer, which is nutritious.

If you plant Chinese cabbage, organic fertilizer is its best fertilizer, because Chinese cabbage mainly grows vegetatively and grows very fast, and the nutrient content of organic fertilizer can be fully absorbed by Chinese cabbage, so organic fertilizer is its best fertilizer.

When planting Chinese cabbage, use a large amount of organic fertilizer as base fertilizer, because the growth rate of Chinese cabbage is faster, the growth amount is larger, so we must use a large amount of organic fertilizer as base fertilizer, generally 4 5 tons of rotting high-quality organic fertilizer per mu, using furrow application or hole application, the fertilizer is applied to the soil Chinese cabbage top dressing should be based on the principle of "light before and heavy after", in the rosette period to the early stage of the core is the focus of top dressing.

The demand for nitrogen, phosphorus and potassium fertilizers for planting Chinese cabbage is slightly different, and it can be fertilized in an appropriate amount according to different periods. It is best to use more farm manure, that is, animal manure such as (chicken manure, pig manure), etc., which is easier to be absorbed by Chinese cabbage, so that Chinese cabbage grows better.

What is the law of Chinese cabbage need fertilizer? How much fertilizer does Chinese cabbage need to grow and develop, and when is it good to fertilize? How to fertilize Chinese cabbage well, what fertilizer to use each time, and how much fertilizer to apply each time per mu of land? The following is a brief introduction for netizens' reference.

How to fertilize Chinese cabbage and what fertilizer is good to use?

Chinese cabbage fertilization rules.

Chinese cabbage is a vegetable that requires more chemical fertilizers, and generally needs to absorb about kilograms of nitrogen, kilograms of phosphorus, and kilograms of potassium for every 1000 kilograms of Chinese cabbage produced.

There were significant differences in the nutrient requirements of Chinese cabbage at different growth stages. In general, the nutrient absorption at the seedling stage was less, and the absorption only accounted for the total absorption, the absorption accounted for the total absorption, and the potassium absorption accounted for the total absorption.

At the rosette stage, the growth of Chinese cabbage accelerates and nutrient uptake increases rapidly. Nitrogen absorption accounts for the total absorption, phosphorus absorption accounts for the total absorption, and potassium absorption accounts for the total absorption.

In the early and middle stages of cabbage balling, the growth is fastest and the nutrient absorption is the greatest. Nitrogen uptake accounted for 30% to 52% of the total, phosphorus uptake accounted for 32% to 51%, and potassium uptake accounted for 44% to 51%.

After harvesting, the nutrient uptake decreased significantly, accounting for 16% to 24% of the total, 15% to 20% of the total phosphorus uptake, and less than 10% of the total potassium uptake. Generally speaking, the period when Chinese cabbage needs fertilization the most is the rosette stage and the early stage of pilling, which is the critical period for Chinese cabbage yield formation and fertilization.

How to fertilize Chinese cabbage and what fertilizer is good to use?

Fertilization method and amount of cabbage.

1. Planting Chinese cabbage should be based on sufficient organic fertilizer, generally 4 5 tons of high-quality organic fertilizer per mu, using trenching or digging holes, and fertilizing into the soil.

2. Cabbage topdressing should be based on the principle of "light before heavy after", and it is the focus of top dressing in the rosette period to the early stage. Generally, 8 10 true leaves in Chinese cabbage, 10 15 kg of 45% compound fertilizer per mu are applied, 4 5 kg of granulated urea per mu is applied in the rosette stage to the early stage, and 5 kg of potassium fertilizer is used at this time, which can significantly improve the yield and increase the net vegetable rate.

3. In the north, Chinese cabbage is prone to calcium deficiency and dry burning heart disease, so granular calcium nitrate solution can be sprayed in the early stage. For many lightly acidic soils in South China, Chinese cabbage is prone to boron deficiency, and can be sprayed with fertile leaf boron fertilizer, which has a good control effect.
