How to fertilize cabbage? What should we pay attention to?

What is the best fertilization method is the fusion of soil fertilizer and chemical fertilizer, such as if there is phosphorus fertilizer, use phosphate fertilizer with soybean cake, or fried soybeans, manure buns, this is a very good soil fertilizer, and fertilizer can be applied together, and the water in the middle and late stages will follow closely to ensure that when it comes to selling, the top of the vegetable tree is firm and big, and it is very delicious. On the basis of applying foot fertilizer, the general old vegetable garden, the soil layer fertilizer rate is higher, and the organic fertilizer used can be appropriate and <>

If it is on a new vegetable field, the fertilizer efficiency of the soil will be insufficient, and we should reapply organic fertilizer or phosphate fertilizer mixture as base fertilizer. Generally, at the seedling promotion stage, we fertilize the Chinese cabbage after the budding stage. Because the planted Chinese cabbage is inevitably uneven, it is dense and needs to be solved by supplementing seedlings.

At the end of seedling replenishment, top dressing should be carried out immediately to promote seedling fertilizer. It is best to maintain the soft soil layer before fertilization, and promote the seedling fertilizer father to generally use urea watering. Here's how:

During irrigation, water is sprinkled into the inlet of the running water and poured into the cabbage ditch.

The advantage of this is that it does not damage the roots, and urea can be effectively and quickly melted to make the fertilizer effective. Until the leaves of the Chinese cabbage grow out, the main stem grows to about ten centimeters, in the case of insufficient bottom fertilizer or no fertilizer, it can be a small amount of seedling fertilizer, an acre of land can use about six kg of urea, to promote the growth of Chinese cabbage, fertilization should be the key to apply seedlings, zombie seedlings, to promote its production of vigorous seedlings. The second half of the chemical fertilizer, which belongs to fertilization.

The effect of fertilization is directly related to the production and quality of cabbage during the picking period.

Nitrogen fertilizer can be used for fertilization, the amount of nitrogen fertilizer per mu is calculated according to 50 catties, nitrogen fertilizer is increased with watering, watering 2 times with nitrogen fertilizer, and the interval of watering is more than 7-10 days. What is the best fertilization method is the fusion of soil fertilizer and chemical fertilizer, such as if there is phosphorus fertilizer, use phosphate fertilizer with soybean cake, or fried soybeans, manure buns, this is a very good soil fertilizer, and fertilizer can be applied together, and the water in the middle and late stages will follow closely to ensure that when it comes to selling, the top of the vegetable tree is firm and big, and it is very delicious.

When planting cabbage and fertilizing, you must pay attention to the basic fertilizer is enough, when the cabbage grows leaves, the rhizome reaches 10 cm, you can fertilize a small amount to promote its growth.

How to fertilize:1According to soil fertility conditions and target yield, the amount of nitrogen, phosphorus and potassium fertilizer should be optimized.

2.Base fertilizer is the main fertilizer, and base fertilizer is combined with top dressing. Top dressing is mainly nitrogen and potassium fertilizer, and trace elements are appropriately supplemented.

Note: After the rosette stage, the top dressing management should be strengthened, and the top dressing should be increased once in the early stage of the heart, and the nitrogen top dressing should not be used two weeks before harvesting.

Before planting cabbage, it is necessary to apply enough basal fertilizer in the soil, basal fertilizer can improve the fertilizer of the soil, basal fertilizer can choose to apply farmhouse fertilizer, the specific amount of fertilizer should be determined according to the planting area, usually each mu needs about 4800 to 5000 kg of basal fertilizer, and then with an appropriate amount of compound fertilizer.

Due to the long growth period of cabbage, the demand for water and nutrients is large, and during the growth period of cabbage, it is necessary to keep the ground moist every day, especially during the seedling period. Sometimes it rains a lot, and it needs to be watered even more, because the rain may splash the soil on the cabbage leaves, and the leaves have too much soil on them, which affects the growth of the cabbage, and it needs to be watered to wash the soil away.

After sowing the cabbage, wait until a stage of growth, and watch the cabbage grow four or five leaves, you need to set the seedlings, and after the cabbage seedlings three times, you need to set the seedlings. In order to ensure that the cabbage grows well, the heavy and honest Chinese cabbage can be harvested after autumn, and the seedlings should be fertilized in time. So do you need to water after fertilizing?

When is the watering time to achieve a reasonable combination of water and fertilizer?

If you are a professional vegetable farmer, you can take advantage of the watering or rain, when the vegetable field is still wet, directly sprinkle the fertilizer in the vegetable furrow, although it is a bit wasteful, but this saves time and effort, but it should be noted that the fertilizer can not be sprinkled on the leaves. Rural people grow vegetables, most of them are vegetable gardens in front of their homes, and in order to eat pure natural and clean vegetables, they naturally do not use chemical fertilizers.

Most of the small vegetable gardens in front of their own doors use organic fertilizer, and those who are particular about it will use soybeans or peanut cakes as fertilizer. After the cabbage seedlings are set, it is necessary to top dressing in time, no matter what fertilizer is used, it is best to water immediately after fertilization. If you really don't have time, watering every day or two is fine, but it's best not to delay too long.

After fertilizing, be sure to water the cabbage thoroughly. Because most people apply human or animal manure fertilizer to cabbage, if the amount is too large and close to the cabbage root, it is easy to injure the cabbage root due to too much nutrients. Some people just didn't water it in time after fertilization, and it didn't rain in the sky, so they burned the vegetable roots.

Therefore, after the cabbage is fertilized, in order to avoid unnecessary trouble, it is necessary to water directly, so as to reduce the concentration of chemical fertilizer, improve the effectiveness of chemical fertilizer, and achieve the rational use of water and fertilizer, in order to improve the quality and yield of cabbage.

Cabbage needs to be watered directly after fertilization. The best thing is to water every day, be sure to fertilize scientifically, and control the frequency of fertilization.

Cabbage needs to be watered after fertilization, because the concentration of fertilizer is too high, the fertility is too large, and if it is not diluted by watering, it is very easy to burn seedlings.

Yes, it is best to fertilize just after the rain, which can save a lot of effort, can also effectively improve the efficiency, and can also make the fertilizer sprayed very evenly.

It should be fertilized in moderation, not too much at one time, otherwise it will damage its growth.

Nitrogen fertilizer should be applied in moderation. Basal fertilizer is the main fertilizer, and basal fertilizer is combined with top dressing. Top dressing is mainly nitrogen, nitrogen, phosphorus and potassium are reasonably matched, and trace elements are appropriately supplemented.

It is planned to produce about 4,000 kg of fresh cabbage per mu, 2,000 kg of organic fertilizer, 15-20 kg of pure nitrogen, and 4-6 kg of phosphorus (P2O5).

Before planting cabbage, you should apply a little organic fertilizer to him as a base fertilizer, with fertilizer, divided into elemental fertilizer and compound fertilizer, and apply some compound fertilizer superphosphate potassium chloride to it later.

apply sufficient basal fertilizer; Apply good seedling fertilizer;

Grow a fertilizer; Repeat fertilization.

At this time, you should grasp the time, for example, when the cabbage is strong and vigorous, or when the cabbage has pests or pests, and when the soil has no fertility, we must pay attention to the reasonable amount, and then we also need to avoid rainy weather, and when the temperature is relatively high.

Choose fertilization in May, when fertilizing should pay attention to the choice of soap, it is best to choose some potassium fertilizer, so that the roots can be supplemented with a lot of nutrients, and when fertilizing, you must ensure that you do not hurt the roots, so that all can be contacted.

Fertilization can be carried out at the seedling stage. When fertilizing, we must pay attention to the amount of fertilizer, and we need to pay attention to the ratio of fertilizer, you can mix some fertilizers together, but do not have chemical reactions, we must understand these fertilizers, and we must avoid windy and rainy weather when fertilizing.

Cabbage is one of the main vegetables grown in autumn in China. We all know that crops and flowers rely on fertilizer. The high quality and high yield of cabbage are inseparable from fertilizer. So what fertilizer should be applied to the cabbage that you want to grow better? What fertilizer can't be used for cabbage?

What fertilizer should be used to grow cabbage.

1. Farm fertilizer.

Farmhouse fertilizer is also called organic fertilizer, and cabbage fertilizer is generally composed of completely rotten farmhouse fertilizer and a small amount of chemical fertilizer. But before preparing the land, sprinkle farmhouse manure first, and then turn it deep to return the farmhouse manure to the bottom of the soil, which is conducive to the absorption of nutrients by cabbage, and the fertilizer is converted into nitric acid, which is conducive to the absorption of cabbage by the soil.

2. Cabbage compound fertilizer.

There is a preference for fertilizers. Among them, the absorption of nitrogen, phosphorus and potassium is relatively large. Fertilizers based on nitrogen, phosphorus and potassium are important guarantees for the good growth and yield of cabbage.

Compound fertilizer can be used as basal fertilizer and organic fertilizer to cultivate together, and can also be used as top dressing. The base fertilizer is generally 15 kg of potassium sulfate, 25 kg of diammonium phosphate or 15:15:

15. 50 kg of ternary compound fertilizer. Top dressing compound fertilizer should be selected according to the type of fertilizer and the amount of fertilizer should be determined according to the production period of cabbage. Cabbage rosette stage, ammonium sulfate 50 kg or urea 20 kg, potassium sulfate 15 kg, 15 kg.

Kilograms of superphosphate can be coated. After the cabbage station, about 10 kg of urea, 15 kg of superphosphate, and about 15 kg of potassium chloride were added.

3. Foliar fertilizer.

Foliar fertilizer is an important fertilizer to ensure the rapid supply of nutrients and avoid nutrient deficiency in the growth process of Chinese cabbage. Spray potassium dihydrogen phosphate at the flowering stage of cabbage, which can be sprayed once every 10 days as needed, and the concentration is, and the dosage is too large and easy to burn seedlings. Chelated calcium is mainly used to supplement calcium fertilizer to prevent or reduce the occurrence of "dry heartburn" in cabbage.

It is recommended to spray a solution of calcium chloride or calcium nitrate on the leaves of Chinese cabbage 2-3 times. Spraying 5 times every 7 days during the growing season can effectively prevent heartburn in Chinese cabbage.

What fertilizer can't you use for cabbage?

1.Chlorine-containing fertilizers.

Chlorine-containing fertilizers include: ammonium chloride, potassium chloride, calcium chloride, etc., and chlorine-containing fertilizers can only be used in small amounts. Otherwise, it will lead to heavy soil salinity, cause damage to vegetables, and affect the normal growth of vegetables, especially cabbage, try not to use chlorine-containing fertilizers.

2. Urea and ammonium bicarbonate.

Although urea and ammonium bicarbonate can improve the yield of cabbage, it is necessary to control the dosage and do not eat excessively, especially in the late growth stage, excessive nitrogen fertilizer will not only make the cabbage packaging poor, but also the cabbage leaves have high moisture, affecting the taste, and it is also easy to rot during storage. In addition, pests are also prone to occur in the later stages of growth. Top dressing cabbage should not be excessive, should be covered with phosphorus and potassium fertilizer.

3. Insufficient fermentation of farmhouse fertilizer.

If you use poorly fermented farm fertilizer, it is easy to cause pests and diseases, resulting in underground pests, rotten roots, soft rot, etc., so farm fertilizer must be fermented well, otherwise it will not increase the yield, and will also lead to the emergence of various pests and diseases.

The above is the introduction of cabbage fertilization. Cabbage is grown on the basis of fertilization on the feet. A good surface layer can guarantee high efficiency. Therefore, it is necessary to do a good job in fertilization management. Do you have anything to add to your cabbage fertilization?

You can apply basal fertilizer, manure, compost, mixed manure and other organic fertilizers, so that cabbage can grow better. Nitric acid nitrogen, ammonia nitrogen and other fertilizers can not be used for cabbage.

It should be applied farmhouse fertilizer, which may make the cabbage grow better, and you can also apply cabbage compound fertilizer, which can also improve the yield of cabbage. Fertilizers that are not suitable for use should be chlorine-containing fertilizers, urea, ammonium bicarbonate, etc., which are not suitable for use.

There are several kinds of nitrogen fertilizers on the market, such as ammonium nitrogen and nitrate nitrogen fertilizers, among which the common ones are ammonium chloride, ammonium sulfate and ammonium bicarbonate, ammonium nitrate, calcium nitrate, and should be used with caution on cabbage.

Farmhouse fertilizer is used as base fertilizer, and urea is used as top dressing. You can also use compound fertilizer, use 15-15-15 compound fertilizer as base fertilizer, top dressing with high nitrogen type, such as 30-5-5 or 28-6-9, etc., at this time urea top dressing can also be used. Do not use chlorine-containing fertilizers, such as topdressing chlorine-containing fertilizers.

Chinese cabbage is a high-yielding vegetable. In the north, for example, sowing generally begins in July and August. In the past two days, many people began to consult the planting technology of Chinese cabbage, and many people asked how to fertilize Chinese cabbage.

Let's talk about the scientific fertilization method of Chinese cabbage first. Due to the different needs and ratios of nitrogen, phosphorus and potassium in the whole growth process of Chinese cabbage, the proportion of nutrient absorption at seedling stage was small, and the absorption of nitrogen, phosphorus and potassium was less than 1% of the total absorption, and the nutrient demand of Chinese cabbage at rosette stage gradually increased, accounting for about 203,360% of the total, and the nutrient absorption at heading stage was the highest, accounting for about 80% of the total. From the germination stage to the rosette stage, nitrogen absorption is the highest, followed by potassium, and phosphorus is the least.

Potassium is absorbed most during the nodulation phase, followed by nitrogen and phosphorus. According to this law, the following fertilization can be carried out:1.

The base fertilizer should be sufficient.

Generally, the amount of fertilizer per mu of land is about 5000 kg of high-quality rotted farmhouse fertilizer and 40-50 kg of compound fertilizer. It can be ridged and planted. 2.

Seedling fertilizer should be applied skillfully. Generally speaking, the effect of basal fertilizer is slow, and a small amount of available nitrogen fertilizer should be applied as seedling fertilizer. At this point, the first refinement can be made.

After seedling, 5-8 kg of ammonium sulfate per mu was used to promote the growth of seedlings. It should be noted that in order to balance the growth of seedlings, we should focus on the application of small and weak seedlings to promote their formation of strong seedlings, rather than topdressing seedlings that have been applied plantar fertilizer. The three Chinese cabbages are forced to apply "fertilizer" at the rosette stage, and the growth rate and amount are relatively large, so sufficient fertilizer and water need to be supplied.

High-nitrogen fertilizer should be applied as soon as possible, and a small amount of phosphorus and potassium fertilizer should be applied to meet the nutritional requirements of the rapid growth of Chinese cabbage at the rosette stage.

During this period, it is recommended to apply 15-20 kg of urea and 10 kg of potassium sulfate per mu, and water two days after fertilization to ensure that the fertilizer meets the growth needs of Chinese cabbage to the greatest extent. In the later stage, if the rosette grows too fast, dwarf seedlings need to be cultivated to prevent excessive growth of rosette leaves and delay ball setting. 4.

Top dressing should be sufficient at the heading stage. The heading stage is the formation period of the economic yield of Chinese cabbage, and the growth is large, so it is also the stage with the largest demand for water and fertilizer. One-time topdressing can be used in the nodulation stage, which can also be divided into early and middle stages, with the early stage as the main stage.

In the early and middle stages of nodulation, combined with watering, 15-20 kg of ammonium nitrate and 10-15 kg of potassium sulfate per mu were applied, and 1% superphosphate leaching solution could be sprayed on the foliar surface during the core covering period to promote nodulation and prevent dry burning. The above is the scientific fertilization technology of Chinese cabbage during the whole growth period.
