If you want Chinese cabbage to have a high yield, what are the key points of water and fertilizer ma

The growth rate and growth of Chinese cabbage rosette stage are larger, which is an important period for the formation of yield, and is the period for laying the foundation for the ball, the absorption of nutrients increases, and sufficient fertilizer and water ** to ensure the vigorous growth of rosette leaves is the key to high yield. Animal manure, mainly chicken manure, cow manure, deer manure, pig manure, these manure piled together, it will be naturally fermented, it doesn't matter if the fermentation is good or bad, because you apply the manure of these animals to the land, these manure is also fermented at any time, a small amount of available nitrogen fertilizer should be applied at the seedling stage, at this time, the main branch of the seedling reaches a certain height, and produces lateral roots, has a certain ability to absorb water and fertilizer, but the absorption of nutrients is relatively small, apply a small amount of seedling fertilizer, 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. It accounts for about 80% of the total nutrient uptake, so it is necessary to fully ensure the nutrients at this stage**. Chinese cabbage fertilization is mainly based on organic fertilizer, supplemented by chemical fertilizer, mainly based on base fertilizer, supplemented by top dressing, light before top dressing, and attention to the principle of coordinated application of medium and micro elements.

The cultivation season and method of Chinese cabbage are mainly divided into autumn, winter and spring. The plot must be planted in good conditions, with deep and fertile soil and good water retention in sandy loam or light clay soil. Do not combine cropping with cruciferous vegetables.

<> Chinese cabbage grows up after the growth is very good, in the middle of the way to see the form of Chinese cabbage, if there is a lack of fertilizer, you can use some fertilizer to supplement, the development ability and growth of this vegetable is very strong, they grow very fast, it is also resistant to cold, enhance disease resistance, the application of potassium fertilizer can significantly improve the disease resistance of cabbage, reduce the incidence of disease, according to statistics, the application of potassium fertilizer Chinese cabbage disease incidence is only, the incidence of the control area, the incidence is reduced.

There are three key points to pay attention to in the management of high-yield water and fertilizer of Chinese cabbage: 1. The first topdressing should be controlled at the critical time of the rosette stage. Top dressing is mainly based on fast-acting nitrogen fertilizer with potassium fertilizer, and timely irrigation, after water and fertilizer, it enters the core stage.

2. The 2nd-3rd top dressing is carried out in the early and middle stages of the wrapping. Mainly apply nitrogen fertilizer, up to two times, and limit the amount. Nitrogen topping fertilizer was stagnant in the later stage of wrapping.

The amount of nitrogen fertilizer for each top dressing should depend on the growth of cabbage. 3. In the high-yield fertilization of cabbage, in addition to the application of sufficient nitrogen, phosphorus and potassium, the application of medium and trace elements should also be noted.

Fertilization during the growth period of cabbage should increase the amount of nitrogen fertilizer appropriately, and the appropriate combination of phosphorus and potassium fertilizer can improve the disease resistance of cabbage. During the rosette stage, it is usually reapplied once by opening a small furrow 8 or 10 cm deep around the plant and then applying fertilizer. A suitable soil relative humidity of 70%-80% is required.

If it is less than 70%, the rosette will have small leaves and small photosynthetic area, which will affect the yield and quality. Too much water, rosette leaves are long, and the center is delayed, and the ball setting is affected.

In the old vegetable field, the soil fertility is high, and the organic fertilizer can be applied with an appropriate amount. The nutrient ratio of compound fertilizer is mainly nitrogen and potassium, and phosphorus fertilizer is applied. The first top dressing should be done in moderation at the critical time of the rosette period.

The top dressing was mainly based on fast-acting nitrogen fertilizer and potassium fertilizer, and the second and third top dressing was carried out in the early and middle stages of core packing. Mainly top dressing nitrogen fertilizer, up to two times

When the cabbage reaches the rosette stage, it is very critical, this is the critical period for the cabbage to form leaf balls, so the demand for water and fertilizer is relatively large, and the roots will grow in large quantities, the leaves will increase a lot, and the growth rate is also very fast, so there are special requirements for fertilizer and water, but the specific amount is also based on the soil situation. At this time, the fertilizer is mainly ammonium sulfate, which needs about 15-20kg per mu, and 1000kg of farmhouse fertilizer can also be used.

There are many, many farmers who grow Chinese cabbage, but there are very few who know how to fertilize it. To ensure the quality and yield of Chinese cabbage, scientific fertilization is very important. Due to the long growth period and high yield of Chinese cabbage, the demand for nutrients is great.

From planting cabbage to harvesting cabbage, I will explain one by one, I am planting Chinese cabbage, digging the soil loose before planting vegetables, I planted cabbage in three points, the size is good, and I can also plant twelve lanes of vegetables in three points.

The root system of Chinese cabbage is more developed than other vegetables, and most of the root system is concentrated in the soil below 30 cm, so Chinese cabbage has a strong adsorption capacity for nutrients and water. Chinese cabbage is also the same as some vegetables, it is best to avoid planting, prevention and control of bacterial infection, the first step is to apply foot fertilizer, a large number of high-quality organic fertilizer is needed during the growth period of cabbage, generally one acre of land can not be less than 5000 kg, superphosphate or compound fertilizer, the amount per mu is about 50 kg.

<> stir evenly with pesticides and then sprinkle them in the roadway, and then sprinkle the farmer's soil fertilizer, dig the soil over with an iron pry, turn the fertilizer under the bottom, and the fertilizer of the cabbage is finished, and then shovel up the soil on both sides, after the soil lumps are crushed, the Chinese cabbage is mainly top-applied nitrogen fertilizer, which can be fertilized with high nitrogen. 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 supplementing calcium fertilizer and preventing hollowness.

It is to plant cabbage in advance in the ground sprinkled with the manure in the pigsty, the manure in the pigsty should be mixed with the soil to sprinkle, otherwise the strength is too great, for fear of burning the seedlings, and then the appropriate amount of watering the cabbage, because the cabbage is afraid of thirst, can not let the cabbage too dry, the type of fertilization should be organic fertilizer and inorganic fertilizer combined application. Organic fertilizer and phosphate fertilizer are mainly applied as basal fertilizer, and inorganic fertilizer and part of the fast-acting organic fertilizer are used as top dressing, and top dressing accounts for 1 3 of the total amount of fertilizer. Therefore, basal fertilizer should be reapplied in fertilization management.

Chinese cabbage is a fertilizer-loving crop, all crops need fertilizer supply, and if there is not enough fertilizer supply, the crop growth will be slow. According to the determination of the agricultural research department, the proportion of Chinese cabbage's demand for nitrogen, phosphorus, potassium and other large elements must be applied in time.

Yes, first of all, the fertilization of our growers in the Chinese cabbage seedling stage should be combined with the seedlings, and the seedling fertilizer should be lightly applied in the field, and the mixed application of rotting farmhouse fertilizer and urea per mu should be applied, so as to promote the healthy growth and development of Chinese cabbage seedlings.

In the north, cabbage can be said to be a common vegetable at home throughout the year, after all, cabbage is not only stored for a long time and contains a lot of nutrients required by the human body, but since most people's cabbage at home is grown by themselves, I will take a look at how to do a good job of water and fertilizer management of Chinese cabbage.

1. First of all, it is necessary to combine fertilization and thinning of Chinese cabbage seedlings, ploughing in the field, fertilization at the seedling stage should be applied lightly, and rotted farmhouse fertilizer and urea should be applied per mu to promote the robust growth and development of Chinese cabbage seedlings.

2. Entering the rosette stage of Chinese cabbage, growers should pay attention to fertilization. During this period, the growth and development of Chinese cabbage accelerated significantly, and the amount of fertilizer required also increased. Farmers should pay attention to the timely application of fertile plant fertilizer, and apply high-quality farm fertilizer, urea and an appropriate amount of phosphorus and potassium fertilizer per mu.

3. When heading Chinese cabbage, farmers must try to apply high-quality farm fertilizer, urea 20, plant ash or potassium sulfate per mu before heading.

1. When fertilizing Chinese cabbage seedlings, rosette and heading stages, you can spray a strong stem liquid, which can make the Chinese cabbage stems firm and the plants flourish. At the same time, it can also improve the disaster resistance of Chinese cabbage and reduce the amount of pesticides and fertilizers.

2. Pay attention to reasonable watering, Chinese cabbage needs more water during the whole growth period. Farmers should combine fertilization with watering every time, master the technology of small watering at the seedling stage of Chinese cabbage, more watering at the rosette stage, and watering every 4-7 days at the heading stage, so as to improve the quality and yield of Chinese cabbage.

Cabbage likes cold, humid climate, high temperature and drought conditions will grow poorly, cabbage planting in the open field production, so the cultivation season varies from region to region, the warmer region is divided into spring, summer, autumn three stubble, the northern region is divided into spring, autumn two stubble, but most areas are mainly produced in autumn, the autumn temperature is mild, the light is sufficient, the temperature difference between day and night is large, the cabbage grows fast, the nutrient accumulation is high, the quality is good, the yield is high, and it is also conducive to storage.

In the later management of Chinese cabbage, it is necessary to provide it with urea, potassium sulfate-based fertilizer, and dilute the fertilizer to provide balanced nutrition for the Chinese cabbage, and fertilizer should not be sprinkled on the leaves of Chinese cabbage when fertilizing, so as to avoid fertilizer damage to the plant, and it is best to apply fertilizer into the soil of the cabbage roots.

1. Fertilizer selection

When fertilizing Chinese cabbage in the later stage, it is necessary to use urea, potassium sulfate-based fertilizer to provide potassium, nitrogen, phosphorus and other trace elements for the plant to improve its growth rate.

2. Fertilization method

When applying bright round fertilizer to Chinese cabbage, you can apply fertilizer directly to the soil at the root of the plant, and water it once to dilute the fertilizer, or dilute the fertilizer directly with water, and then water it to the Chinese cabbage, so that it can better absorb nutrients, but the fertilizer should not touch the cabbage leaves, so as not to affect the quality.

3. Fertilizer treatment

In the process of fertilization, if there is fertilizer damage, it is necessary to loosen the soil for Chinese cabbage in time, and water it with water, dilute the fertilizer in the soil, and if the fertilizer damage is more serious, it is necessary to pour carbendazim into the roots of Chinese cabbage to help the roots restore healthy growth.

4. Post-management

When cultivating Chinese cabbage, in addition to providing nutrients for it, you can also water the plant every three days to keep the soil moist, and when watering, it is not advisable to water the water at the cabbage heart, so as not to accumulate water at the cabbage heart, resulting in the phenomenon of cabbage rotting.

Chinese cabbage should be fertilized with seedlings. After transplanting and planting Chinese cabbage, thin human manure and urine were used in combination with watering, and seedling fertilizer was applied every 3 5 days. At the same time, it is necessary to pay attention to cultivating and loosening the soil in the vegetable field to promote rooting.

In the pilling period, the use of ternary mixed Chinese cabbage per mu can be sown in holes, can be sown, you can raise seedlings and transplant, but most of them are more live-seeded. Watering the bottom of the water, after the water seeps down, about 10 grains are sown in the hole, the strip sowing can be mixed with fine soil or fine sand and sown, covering about 2 cm of soil, slightly pressing the soil, so as to facilitate the seeds and the soil are closely connected.

<> transplanting and seedling fertilizer. After the Chinese cabbage seeds are sown in the field, because the temperature is relatively high, as long as the soil moisture is good, the seeds will germinate very quickly. Generally, 20-30 days after the emergence of cabbage seedlings, cabbage can be transplanted according to the size of the seedlings.

When transplanting cabbage, it is necessary for the cabbage to grow 2 to 3 leaves, and every 5 to 7 days, it is necessary to top dressing once to improve the stems and leaves of the cabbage and provide the nutrients needed for the future cabbage growth. When the cabbage grows into a heart, it needs to be tied with a rope to prevent it from rotting when it hits the ground.

Chinese cabbage is planted around the beginning of autumn, and now there are still ten days before the beginning of autumn, so it stands to reason that open-air cabbage can be planted. The planting of open-air Chinese cabbage should be planted as much as possible to choose high-quality seeds that are resistant to heat and low temperature and suitable for local planting, and the soil should be planted before planting, and after the seeds are planted, it is necessary to wait for the seeds to germinate and carry out two seedlings, the first time is when the tender plant grows two true leaves, and the plant spacing is kept at about 4cm. The second time is when the young seedlings have grown about 5 true leaves, and the plant spacing should be kept at 9 cm.

It is also necessary to master the spacing, if the spacing is short, that is, it is relatively dense, the cabbage that grows out will not be too large, try to keep a cabbage of one and a half feet, the cabbage that grows out is large, and the yield is also high. In the cultivation of perennial vegetable land, continuous cropping with cruciferous vegetables should be avoided, and the ground cultivation with early beans, early peppers, early cucumbers and early tomatoes can be selected. Grow Chinese cabbage.

After the Chinese cabbage seedlings are set, a shallow ditch of about 8 cm is opened in the middle of the ridge from the plant 18 20 cm, the fertilizer is applied, 30 40 kg of Coside 17-17-17 balanced compound fertilizer is applied per mu or 1000 kg of decomposed organic fertilizer is applied, and then 10 15 kg of ammonium sulfate, 50 100 kg of plant ash, 10 20 kg of superphosphate are added, and the soil is buried and the ditch is sealed immediately after application.

1) Base fertilizer. Before planting, first of all, the basal fertilizer in the soil should be applied sufficiently, improve the fertility of the soil, and promote the better growth of cabbage, the basal fertilizer is mainly based on farmhouse fertilizer, because the nutrition of farmhouse fertilizer is relatively sufficient, which can meet the nutritional needs of cabbage growth, and the specific amount of fertilization can be determined according to the area of the planting land and soil fertility.

2) Promote seedling fertilizer.

In addition to sufficient basal fertilizer, seedling fertilizer also plays a very important role in the growth process of cabbage, because seedlings are very fragile and need to absorb enough nutrients to promote growth, and seedling fertilizer can improve the growth rate of seedlings and strengthen the resistance of cabbage. Seedling fertilizer is mainly used before sowing, sprinkled into various planting holes, and then watered enough.

3) Grow a fertilizer.

Hair fertilizer is a fertilizer applied in the rosette stage of cabbage, the rosette period is a very important period in the entire growth period of cabbage, which directly determines the yield and quality of cabbage, so at this stage must be reasonable fertilizer. However, in the process of fertilization, we must also pay attention to the dosage and concentration to prevent the opposite effect.

4) Bulking fertilizer.

Bulb fertilizer is the last fertilization of cabbage growth stage, at this time the demand for cabbage for non-material will also be very large, you can start to apply bulking fertilizer when the cabbage is not completely wrapped, the proportion of potassium fertilizer in the fertilizer is a little higher, but it is still necessary to pay attention to the dosage, whether too much or too little, will have a certain impact on the final result of cabbage, it is best to mix the farmer's fertilizer and fertilizer together, so the effect is better.
