If you want rape to have a high yield, how do you need to fertilize? What kind of fertilizer to appl

To apply foot fertilizer, the bottom fertilizer is best to use farmhouse fertilizer, such as rape cake, sesame cake after fermentation, it is a good farmhouse organic fertilizer, or use poultry manure as the base fertilizer, if there is no farmhouse fertilizer, you can also use compound fertilizer as the base fertilizer. Rape-based fertilizer is divided into base fertilizer and seed fertilizer. About 3 tons of farmhouse fertilizer per mu of base fertilizer, 11-16 kg of urea, 20-30 kg of superphosphate, and 5-10 kg of potassium chloride are applied.

The lack of base fertilizer is made up for by seed fertilizer, generally with rotting manure and available phosphorus and potassium fertilizer, and the seeds should be soaked in warm water for a day after being exposed to the sun. Allowing the seeds to absorb enough water, swelling and then scooping them up to dry will encourage germination and growth. Next, choose the right plot.

Rapeseed is a crop that requires more boron, and is more sensitive to boron response, and is prone to "flowers but not fruits" on boron-deficient soils, that is, rapeseed continues to bloom without bearing seeds, also known as atrophy and unseeding. Boron fertilizer can be applied as a foliar spray or as a soil application. The late seedling and sprout stages of rapeseed are the peak of nutrient absorption and dry matter accumulation.

At this time, the balanced and timely supply of nitrogen, phosphorus, potassium and other nutrients is the key to high quality and high yield of rapeseed.

Scientific fertilization to promote the reduction of chemical fertilizers. It is recommended to use special slow-release fertilizer for rapeseed, and there is generally no need for top dressing. The amount of fertilization was determined according to the soil fertility and yield target level of the previous crop. Generally, 40-50 kg of special slow-release fertilizer is applied to paddy rape per mu.

The planting of rape is different from the planting of other crops, it likes phosphorus and potassium fertilizer at the same time, and boron is the best, therefore, when planting rapeseed, while ensuring the need for nitrogen, phosphorus and potassium fertilizers, it is necessary to apply boron fertilizer in a timely and appropriate amount of rape The absorption of phosphorus increases with the growth of individuals, but it is relatively balanced, unlike nitrogen and potassium, there is a relatively concentrated peak period, and the demand for potassium from rape to maturity can account for half of it. Spraying boron fertilizer in the early stage of rapeseed extraction can avoid the disease of "flowering but not fruiting" and improve the seed setting rate. At the initial stage of sprouting, spray 60 kg of borax aqueous solution per mu each time, or spray with 50 grams of instant boron fertilizer (liquid boron) and 60 kg of water to spray <>

Before planting rapeseed, organic fertilizer is added to the soil as a base fertilizer, which can effectively promote the growth of plant rhizomes, and then apply organic fertilizer every half a month, and the concentration of fertilizer is not too high.

Seedling fertilizer must be applied in advance to promote the growth of rapeseed before winter and ensure safe wintering. Kilograms of urea or 25 kilograms of ammonium carbonate can be applied per mu. For rapeseed with late sowing period, serious frost damage and poor seedling potential, it should be applied early and more often.

Rapeseed seedling fertilizer should be applied early. Fertilizer should be poured with water. An acre of soil and miscellaneous fertilizer! Before fertilization, tillage and weeding, and flower manure can make up for the lack of fertility in the middle and late stages. For fields with stable growth and insufficient fertility after spring, urea grams, or ammonium sulfate are generally applied per mu.

Field-specific fertilization: Rapeseed fertilization is different, if you want to have high yield, then you should increase 15%-20% on the above fertilization level. The specific amount of fertilization can be applied according to soil quality, soil fertility, seedling condition, base fertilizer, application quantity, etc., and fertilizer can be applied according to the situation of the field.

The specific dosage can be accurately topdressed and supplemented according to the demand rules of each nutrient above.

Rapeseed topdressing mainly chases nitrogen, potassium, boron fertilizer, and nitrogen fertilizer.

Urea is an option.

Potassium fertilizer is potassium chloride.

Boron fertilizer can be borax or boric acid. Generally, 5-6 kg of urea is chased at the seedling stage (about 5 leaf stage) to promote the growth of seedlings and form strong seedlings for wintering, and a small amount of potassium fertilizer can also be added; Jiangxi, Hunan and other areas generally apply good fertilizer before the Spring Festival, apply 5-6 kg of urea and 5-7 kg of potassium chloride to ensure that there are sufficient nutrients for branch growth and podding during the key growth period of rape.

Boron fertilizer should be applied basally, combined with foliar spraying, and borax solution should be sprayed on the foliar surface during the flowering stage of rapeseed buds. If the base fertilizer is not sprinkled with boron fertilizer, it can be sprayed 2-3 times during the growth period of rape (seedling stage, bud flowering stage) to prevent rapeseed from "flowering but not fruiting". Boron fertilizer can be sprayed at the same time as the flowering stage of rape buds, and potassium dihydrogen phosphate can be added at the same time.

Combined with the prevention and control of sclerotinia and downy mildew.

and other agents together, it can improve the fullness of rape pods.

At present, the effect of rapeseed special slow-release fertilizer is good, and one-time fertilization can be managed for one season, which can save the labor cost of fertilization.

When rapeseed is seeded, 35-45 kg of slow-release fertilizer can be applied at one time, and if the growth is weak in the later stage of rapeseed growth (from sprouting to flowering), due to appropriate topdressing or foliar spraying, if the growth is good, there is no need for topdressing.

You can use organic fertilizer throughout the growth process, powdered is good, and you can use 500-1500 kg per mu according to soil fertility.

Rapeseed needs a lot of fertilizer, and in order to promote high yield through fertilization, we must strive to do two things: first, apply appropriate fertilizer, which should determine the required nutrients according to the characteristics of rape; Second, apply sufficient and sufficient fertilizer to ensure adequate nutrition and high yield. In short, fertilization should be done with the right medicine and sufficient fertilizer. The amount of basal fertilizer applied to rapeseed is mainly in quantity, but it is also necessary to choose the appropriate fertilizerThe amount of basal fertilizer applied in rapeseed is closely related to soil fertility, climatic conditions and total amount of fertilizer.

Here is a judgment criterion, that is, to determine the final amount of basal fertilizer according to the total amount of fertilizer.

<> If the total amount of fertilizer is large, the basal fertilizer can account for about 70% of the total fertilizer amount; If the total amount of fertilizer is small, the basal fertilizer can account for 30% to 40% of the total fertilizer application; If the amount of fertilizer is moderate, the basal fertilizer can account for about 50% of the total fertilizer amount. The amount of fertilizer has a beginning and an end, so the type of fertilizer should also be clear. The application of basal fertilizer to vegetables is generally based on organic fertilizer, and rape is no exception.

Rape can be applied with 4,000 kg of base fertilizer per mu, combined with soil tillage application. In addition, in order to achieve the effect of increasing yield, 100 kg of phosphostone powder can be applied per mu, which can achieve a good effect of increasing yield.

Rapeseed topping should be done in a timely and appropriate amount to do a good job in the topping application at the germination stage. The reason why the top application of sprout moss fertilizer is emphasized here is that this period is the two vigorous periods of vegetative growth and reproductive growth of rapeseed, and timely and appropriate top application can achieve the effect of increasing yield by 17% and 26%. Therefore, in order to achieve high yields, it is necessary to do a good job of external application at the bud stage and moss stage of rape.

Here's how to top it. The best time to apply fertilizer is when the moss is 0 10 cm high, too early or too late is not conducive to the effect of fertilizer. The amount of top dressing, 10 12 kg of pure nitrogen fertilizer or compound fertilizer can be applied to each mu of rapeseed.

On the day of fertilization, do not apply in the morning when the dew is not dry, be sure to fertilize when there are no water droplets on the leaves, and stick to the strip application. In addition, there is another fertilization method that can achieve the effect of increasing yields, and that is to spray borax fertilizer on the foliar surface. It is recommended to spray borax with 120 kg of aqueous solution per mu until the flowering stage.

If you want rape to have a high yield, then it should be potassium fertilizer, it is best to eat fertilizer once a week, and if the growth is not good, you can eat phosphate fertilizer.

Now carry out scientific and effective fertilization, choose soil with good air permeability, regularly carry out hydroponic management, spray pesticides appropriately, and prune some bad branches and leaves to ensure a small amount of many times. This will allow fertilization to take place.

During the growth period of rapeseed, more compound fertilizer should be sprayed, organic fertilizer should also be sprayed, and more watering is required, so that the rape can be successfully grown.

During the growing period of rapeseed, compound fertilizer should be sprayed more, machine fertilizer should be sprayed, and more watering should be used to grow rapeseed.

It is necessary to strengthen field management, supplement organic fertilizer in time, use compound fertilizer, pay attention to the fertility of the soil, pay attention to the temperature of the outside, and water regularly.

First of all, two tons of organic fertilizer per acre are used before planting. During the growth period, 80 catties of urea per mu are used for top dressing.

Early application of seedling fertilizer. Rapeseed seedling fertilizer should be applied appropriately early, should account for 10-15% of the total application amount, and generally use 10 quintals of human manure and urine plus 5-7 kg of urea, or 10-15 kg of ammonium carbonate. The application of chemical fertilizer should be determined according to the weather and soil moisture, and can be applied directly when the soil moisture is high, and it is best to mix the fertilizer with water.

Reasonable and appropriate fertilization should be carried out, and organic fertilizer or nitrogen fertilizer can be used when topdressing rapeseed can improve the yield of rapeseed.

Fertilizer should be applied many times, so that the rape can get more nutrients and will grow better.

When the seedlings are just growing, you can fertilize them, spray more compound fertilizer, zinc fertilizer, potassium fertilizer, and then spray a little fertilizer water when they are almost ripe, so that they can grow healthier. It will also grow better.

Fertilization can be done through the growth of rapeseed, the process of rapeseed growth can be controlled, fertilization is carried out according to the relevant time, and water and fertilizer management must be carried out.

You can give rape some high-quality soil miscellaneous fertilizer, and then carry out top dressing, loosening soil, watering, etc. at the seedling stage to make rape grow better.

Fertilization is the key to the growth of rapeseed, which needs to absorb a large amount of nutrients in order to achieve the stable goals of long spring hair, strong moss branches and more pods, so scientific management is very important. Rapeseed has a crispy texture with a slightly bitter taste. It contains a variety of nutrients and is rich in vitamin C.

Its seed oil content is 35-50%, which can be extracted from oil, and its rapeseed oil is rich in fatty acids and vitamins with high nutritional value. Not only is it a good edible vegetable oil, but it also has a wide range of industrial uses. And rape to plant well, fertilization can not be less, today will take you to understand the fertilization method of rape, do not know friends can take a closer look.

<> apply sufficient amount of base fertilizer, generally with 1000 1500 kg of compost per mu, 20 25 kg of phosphate fertilizer, mixed with topsoil after land preparation, and at the same time with 1500 2000 kg of pig manure water, mixed with an appropriate amount of chemical nitrogen fertilizer and applied to the seedbed soil and fertilizer bed soil. Before and after the seedlings are set, the mu is watered 2 3 times with 500 750 kg of rare human and animal manure. The soil is dry, the seedlings are thinner, and the seedlings are moist and the seedlings are strong.

In order to control the 4 5 leaf stage, stop fertilization and watering, squat seedlings, and prevent the growth of seedbed stage.

Early application of seedling fertilizer, when 80% of the seedbed out of the seedlings, 750 kg of diluted human manure fertilizer per mu or about 4 kg of urea mixed with water to prevent rape seedlings from growing slowly after 3 to 4 leaf stages, and the leaves are red. If the bottom fertilizer is sufficient and the seedlings grow vigorously, it is not suitable for top dressing, and the seedlings should be refined at the 4 5 leaf stage to prevent the formation of vigorous growth and tall seedlings. Canola prefers to grow in cold climates.

According to its growth habits, it is best planted in late March in spring. Otherwise, if planted too early, oilseed rape will be susceptible to low temperatures and produce chilling injury.

The base fertilizer is mainly organic fertilizer, supplemented by chemical fertilizer, which lays a good foundation for rapeseed life. 2000 kg of ordinary organic fertilizer, 25-30 kg of 45% ordinary compound fertilizer, and kg of borax per mu. How to Apply:

Combined with tillage and land preparation, deep application of organic fertilizer, compound fertilizer and boron fertilizer, to avoid too shallow fertilization, so as not to cause fertilizer in the middle and late stages of rape.

It is necessary to pay attention to the frequency of fertilizer application, sometimes do not apply fertilizer frequently, and can also be matched with different fertilizers, which can improve the overall economic benefits and make full use of fertilizers. Try to use a small number of times.

Rapeseed must eat enough fertilizer when planting, the fertilizer applied at each stage is not the same, and the fertilization should be stopped in the period of four or five leaves to prevent the phenomenon of growing in the seedbed stage.

How to choose the right time for rape and pay attention to the nutritional balance of fertilization; The method of fertilizing rape can be to apply some urea and then supplement with potassium fertilizer.

Rape is a more common vegetable in life, most people will choose to plant rapeseed at home, fertilization in the process of planting rape is actually a more important praise, because rape is a very fertilizer-resistant crop, the root system is also more, so you must apply foot fertilizer before fertilization, otherwise it is easy to affect the yield and quality of rape. In the rapeseed growth cycle should also be reasonable top dressing, so as to ensure that the rape is able to consume enough nutrients, in the rape fertilization, you can use organic water-soluble fertilizer, this fertilizer is rich in nutrients, is able to improve the rapeseed disease resistance and lodging resistance. And when fertilizing, it is also necessary to pay attention to ploughing and deep application of the soil.

The demand for fertilizer in rape during the growth period is relatively high, especially in the flowering period, the demand for fertilizer is relatively high, especially for nitrogen fertilizer, which will be more than potassium fertilizer. Therefore, in the process of topdressing rapeseed, we should ensure that the base fertilizer is sufficient, and then add some nitrogen fertilizer, but in the process of topdressing, we also need to adjust the amount of fertilizer appropriately according to different land and rapeseed growth.

When rape flowers enter the flowering period, they must be sprayed with boron on the foliage of rape flowers in time, because if the boron in the soil is insufficient, rape flowers will not be particularly solid, which will cause some physiological diseases, which may have a certain impact on the yield of rape flowers. Fertilization must be principled, not blind fertilization, must use different fertilization methods and links, so that rape flowers can fully absorb nutrients, so as to achieve the effect of increasing yield, otherwise it will have an impact on rape.

Finally, rape is divided into spring rape and winter rape, and there will be certain differences between the two, so in the pre-trembling process of planting, it is also necessary to fertilize according to the rape in different seasons.
