How many types of cake fertilizer are there? How is cake fertilizer used to grow vegetables?

Cake fertilizer is the residue left after the oil seeds are pressed, which can be used as fertilizer.

There are many types of cake fat, among which the main ones are bean cake, vegetable cake, hemp cake, cotton cake, peanut cake, paulownia cake, tea cake, etc. The nutrient content of cake fertilizer is different due to different raw materials and different methods of oil extraction, and the content of various nutrients is also different. Generally, the water content is 10 to 13 percent, and the organic matter is 75 to 86 percent, and it is an organic fertilizer with more nitrogen.

Cake fertilizer can be used as base fertilizer and top dressing, and the cake fertilizer must be broken before application. If it is used as basal fertilizer, it should be applied to the soil 7 to 10 days before sowing, and can be applied in strips or holes on dry land, mixed with the soil after application, and do not close to the seeds, so as not to affect the germination of seeds. The amount of cake fertilizer should be applied according to the soil fertility and crop varieties, and the varieties with low soil fertility and fertilizer tolerance should be applied more appropriately; Otherwise, the amount of application should be appropriately reduced.

Cake. It is an oily seed that has been extracted.

Oil. The post-dregs are called cake fertilizer when used as fertilizer. Cake fertilizer is rich in nutrients, and this kind of resource is generally advocated over the stomach.

Return to the field. or comprehensive utilization. However, it is important to note that some cake pulp contains toxins such as:

Cottonseed cake. Contain.

Gossypol. Tea seed cake. Contain. Saponin.

Tung seed cake contains.

Tungic acid. and saponin, etc., which are not easy to be used as feed. There are many types of cake fertilizer in China, mainly including.

Soy cake. Meal,

Peanut cake. Sesame cakes.

Canola cake. Cottonseed cake, tea seed cake, etc. Farmers generally use it as a high-quality organic fertilizer.

Giving. Crops with high economic value such as melons, fruits, fruit trees, and flowers.

1) The nature of cake fertilizer. China's cake fertilizer contains 75%, 85% organic matter, nitrogen.

Phosphorus pentoxide.

Potassium oxide. It also contains proteins, amino acids, trace elements, etc. Canola cake and soybean cake also contain crude fiber, 6% calcium, choline. In addition, there are certain amounts of niacin and others.

Vitamins. substances, etc. The nutrient content of the main cake fertilizer is shown in Table 47.

Table 47: Reference values of nutrient content of common cakes (%)

Table 47: Reference values of nutrient content of common cake fertilizers (%) continued)-1

The nitrogen in the cake fertilizer is in the form of protein, and the phosphorus is in the form of.

Humic acid. and its derivatives and lecithin and other forms exist, potassium is mostly water-soluble. Cake fertilizer is a kind of delayed organic fertilizer, which must be decomposed by microorganisms before it can be exerted.

Effect. Cake fertilizer contains more nitrogen, carbon to nitrogen ratio.

c n) low, easy.

Mineralization. Because it contains a certain amount of oil, it affects its decomposition rate. The decomposition rate of different cake fertilizers was different under the condition of gas dislike, and the decomposition of sesame cake was faster, and the decomposition of tea seed cake was slower.

Soil texture. It also affects the decomposition of cake fertilizer.

Nitrogen. of preservation. Sandy soil is conducive to decomposition, but poor nitrogen retention. Clay decomposes slowly in the early stage, but it is conducive to nitrogen preservation.

2) Rational application of cake fertilizer. The cake fat is of high quality.

Organic fertilizers. It has complete nutrients, long-lasting fertilizer effect, and optimizes crops.

Rhizosphere. The role of ecological environment is suitable for all kinds of soil and a variety of crops, especially for melons and fruits, flowers, cotton, tobacco and other cash crops, which can significantly increase yield and improve quality. Cake fertilizer can be used as base fertilizer and top dressing.

When making base fertilizer, it does not need to be decomposed, and can be applied directly after crushing, generally applied 2 to 3 weeks before sowing, turned into the soil, in order to fully decompose. Cake fertilizer cannot be applied at the time of sowing, because its decomposition in the soil will produce high temperature or generate various organic acids, which is not conducive to seed germination and seedling growth. When cake fertilizer is used as top dressing, it should be decomposed, which is conducive to the absorption and utilization of crops.

Cake fertilizer fermentation is generally used with compost or.

Manure. The method of mixing and stacking, or soaking in water for a few days, can be applied in the ditch or hole next to the crop, and the dosage is generally about 50 kg per mu. When cake fertilizer is applied directly, an appropriate amount of insecticide should be mixed to prevent attraction.

Underground pests.

As long as it is fully decomposed, the effect can be used. According to laboratory analysis, rapeseed cake contains 32%-36% protein, the amino acid content in its protein is relatively complete, and the content of methionine is higher than that of soybean cake, in terms of minerals and vitamins, rapeseed cake is much richer than soybean meal, phosphorus content is 1 times higher than soybean meal, and 70% is inorganic phosphorus, selenium is 8 times that of soybeans, in vitamins, choline, folic acid, niacin are times, times, times.

Soybean cake fertilizer is slightly better than rapeseed fertilizer, and now organic non-GMO soybean cake is used for ecological farming, ecological planting, fishing or something. Very good. High protein content, fertilizer is the best.

In addition, the effect can be used after fully decomposing. According to laboratory analysis, rapeseed cake contains 32%-36% protein, the amino acid content in its protein is relatively complete, and the content of methionine is higher than that of soybean cake, in terms of minerals and vitamins, rapeseed cake is much richer than soybean meal, phosphorus content is 1 times higher than soybean meal, and 70% is inorganic phosphorus, selenium is 8 times that of soybeans, in vitamins, choline, folic acid, niacin are times, times, times.

Cake fertilizer is no stranger to everyone, and it is a fertilizer made from peanuts, beans, sesame and other substances left after oil extraction. No matter what kind of fertilizer, it contains a lot of organic matter and a lot of elements. Although cake fertilizer is good, it is also a fertilizer commonly used by farmers, but some farmers still have some mistakes when using it, and these two points are very common.

First, it is not ripe and is applied directly.

Many farmers have been using cake fertilizer when they first started growing vegetables, but they have never rotted and used it directly. The protein and sugar in the cake fertilizer will burn the seedlings when they are decomposed, affecting the growth of the plants. Therefore, water should be added for fermentation in advance before use, so that it can become organic fertilizer, especially when topdressing is used directly, which is not conducive to the growth of vegetables.

Second, when applying cake fertilizer, add a large amount of chemical fertilizer.

In this case, in order to meet the growth of crops, fertilization should be matched with some fast-acting fertilizers. However, many farmers do not know the nitrogen, phosphorus and potassium content of cake fertilizer, and when adding fertilizer, they think that the more fertilizer they use, the better, which wastes a lot of money and does not help to improve the yield.

Cake fertilizer is an organic fertilizer with more nitrogen, and less phosphorus and potassium, if too much nitrogen fertilizer is applied, it will cause excess vegetative growth and vigorous seedling growth. Therefore, it is necessary to pay attention to the supplement of phosphorus and potassium fertilizers when using. When the cake fertilizer is fermented, chemical fertilizers containing phosphorus and potassium elements should also be appropriately added.

If it is fermented 100 catties of cake fertilizer, you can add 5 catties of superphosphate and 6 catties of potassium fertilizer, and then add an appropriate amount of water for fermentation and rotting. Under normal circumstances, it takes about ten days for the cake fertilizer to ferment, and it can be applied after fermentation. If it is used as a vegetable top dressing, combined with watering, the quality and taste of vegetables are greatly improved.

Therefore, when using organic fertilizer, we must be scientific and reasonable, avoid the above two misunderstandings, and have a correct understanding of cake fertilizer. When mixed with chemical fertilizers, chemical fertilizers cannot be used without chemical fertilizers, nor can they be used more. It is necessary to combine the law of vegetable fertilizer demand and the actual economic problems, and reasonably match cake fertilizer and chemical fertilizer, so as to save costs under the premise of planting the same yield and quality.

Cake fertilizer is a high-quality organic fertilizer, nutrition is more comprehensive, more suitable for growing vegetables, in the use of cake fertilizer to use the following methods to grow vegetables, 1, cake fertilizer before use, it is best to ferment. Put the rapeseed cake or soybean cake in a container, add brown sugar or microbial bacteria, and stir with water. 7 In 10 days, the fat of the loaf will be completely rotten.

Cake fertilizer can be used as a base fertilizer and mixed evenly with the soil. If it is made into fertilizer, it should be added with more water, sealed well, and fermented for 2 to 3 months, which is suitable for use as top dressing.

2. The cake fertilizer is directly buried in the soil, and it is recommended to add microbial fertilizer to increase beneficial biological bacteria, promote nutrient decomposition, and facilitate the absorption of crops. However, this method is more expensive, and if you are not in a hurry to plant, it is best to ferment according to the first method before using it. Growing vegetables in the vegetable garden, many friends do not have a good grasp of the amount of cake fertilizer, and rely entirely on feeling fertilizer.

It is generally recommended to apply 50 100 grams per hole, or 100 200 catties per mu. The nutrients in cake fertilizer are comprehensive, but the fertilizer needs different rules in the process of vegetable growth. Growing leafy greens requires a lot of nitrogen and a small amount of potassium, and the use of cake fertilizer can fully meet the growth needs.

When planting tomatoes, cucumbers, melons and other melons and fruits, it is recommended to add high potassium fertilizer when topdressing cake fertilizer, so as to meet the expansion of fruits and improve yield and taste.

Therefore, when we use cake fertilizer, we should pay attention to two aspects: first, use it after fermentation. Second, when topdressing cake fertilizer, use potassium fertilizer.

Vegetable garden or balcony to plant vegetables and flowers, cake fertilizer is still a better fertilizer, containing comprehensive nutrients, improve the yield and quality of vegetables. In vegetable gardens where vegetables are grown all year round, the application of cake fertilizer can also prevent soil compaction and improve soil fertility. When cake fertilizer is used in vegetable gardens, some farmers bury cake fertilizer directly in the soil, or cook cake fertilizer and put it in the soil.

Cake fertilizer is some beans, seeds, residues left by oil extraction, etc., generally peanut cake fertilizer, soybean cake fertilizer, hemp residue, etc., is a very common organic fertilizer, flower friends often cake fertilizer when raising flowers, it contains sufficient nitrogen, phosphorus, potassium fertilizer, at the same time, it will also contain some organic matter, protein, etc. After use, it can improve the quality of the potting soil, make the potting soil more fertile, loose and breathable, and so on.

When using, you should pay attention to some small details and tips, so that you will not burn the roots, nor will it affect the growth of the plant, but will only promote its growth.

When using cake fertilizer to fertilize flowers, be sure to pay attention to these:

If there is no fully rotted and fermented cake fertilizer, put it directly in a small potted plant, especially close to the root system, which is easy to burn the roots of the flowers, causing the leaves to turn yellow and ineffective. If you water it again and the ventilation is not good, it will be easy to grow insects.

So keep this in mind, for small potted flowers raised indoors, if you want to use cake fertilizer, you must first ferment and rot, you can break the cake fertilizer, and then put it in an empty oil drum or beverage bottle, add four-fifths of the water, and then leave it for a period of time.

When the temperature is high, it takes about more than a month, and then when you use it, you can water it directly into the pot, which can promote the young leaves of the flowers to bloom more, the flowers to bloom more, and it will not burn the roots, and the soil becomes more fertile and better.

What is Cake Fat? What is the guiding significance of our daily flower cultivation?

Cake fertilizer: cake fertilizer, also known as oil withering, is the residue left after the squeezing of plant seeds with more oil content, is the traditional high-quality farm fertilizer in China, because of its good fertilizer efficiency, low yield and high quality, generally used in vegetables, fruit trees and other crops with high economic value. There are many varieties of cake fertilizer, commonly used in agricultural production are soybean cake, rapeseed cake, peanut cake, sesame cake, cottonseed cake, sunflower seed cake and other cake fertilizer contains a large number of organic matter, protein, residual oil, vitamins and other components, the nutritional value is very high, is the production of pollution-free fruit tree high-quality fertilizer; Some are still good livestock and poultry feed, such as soybean cake, peanut cake, sesame cake, etc., it is recommended to use it as feed first and then use it as fertilizer.

Cake fertilizer is an organic fertilizer that mainly contains nitrogen and contains a considerable amount of phosphorus, potassium and a variety of trace elements.

Nutrient content of several types of cake fertilizer (air-dried basis).

The nitrogen content of legume crop oil cake was the highest, reaching more than 6%. Rapeseed cake, castor seed cake, flax seed cake and sesame cake had a higher phosphorus content of more than 7%, and the nitrogen and phosphorus content was the lowest in tea seed cake. The content of potassium was higher in sunflower seed cake and soybean cake. Flax seed cake, sunflower seed cake and tea seed cake had a higher content of crude organic matter, all of which were more than 90%.

The nitrogen in cake fertilizer is mainly in the form of protein, the phosphorus is mainly in the form of phytic acid and lecithin, and most of the potassium is water-soluble, which can be directly absorbed and utilized by crops. Because cake fertilizer contains more nitrogen, C n is relatively narrow, and it is generally easy to mineralize, but because it often contains a certain amount of oil, and the tissue is dense and lumpy, it affects the decomposition rate. In order to speed up the decomposition, the cake fertilizer should be crushed, the finer the crushing, the faster the decay and decomposition, and the faster the fertilizer effect.

The fertilizer efficiency of cake fertilizer is high and long-lasting, suitable for all kinds of soil and crops, and is used for pollution-free fruit tree production, which can not only increase yield, but also have a good effect on improving the quality of fruit trees. Cake fertilizer can be used as base fertilizer or top dressing. Cake fertilizer should be crushed before use.

When making base fertilizer, it is recommended to ferment first and then apply, but it can also be applied directly, direct contact with the root system of fruit trees should be avoided, and it should be applied deeply, with a depth of less than 10 cm, and the soil should be covered after application. The unfermented cake fertilizer should strictly avoid direct contact with the seeds, so as not to affect the germination of the seeds. When making top dressing, it must be fermented first to avoid burning seedlings.

The fermentation of cake fertilizer mostly adopts the method of dipping, mixing the crushed oil cake with human feces, urine or water and soaking until it is heated, and it can also be mixed with compost manure and stacked for fermentation.

Cake fertilizer is the residue left after the seeds of oil are pressed, commonly known as oil cake, also known as oil dry. These residues can be directly applied as fertilizer, and there are many types of cake fertilizer, among which the main ones are bean cake, rapeseed cake, hemp seed cake, cotton cake, peanut cake, paulownia cake, tea cake, etc.

The cake contains 75%-85% organic matter, nitrogen (N), phosphorus (P2O5), potassium (K2O), protein and amino acids. The nitrogen content in the cake fertilizer is more, most of them are crude protein, easy to decompose, generally used as top dressing, can provide more nitrogen for crops**, if the cake fertilizer is cooked and then applied to the soil, the fertilizer effect is faster, and the fertilization of vegetable fields is generally used.
