Can rapeseed cake be directly used as fertilizer on the tree?

Canola cake can be sprinkled directly in the pot as fertilizer. However, the rapeseed cake absorbs a large amount of water when it is ripe, so it is necessary to let the rapeseed cake manure absorb enough water before it is ripe, so that most of the nutrients are inorganic and easier to be absorbed and utilized by crops.

The by-products of rapeseed oil extraction contain high protein and amino acids, which are relatively balanced. Rapeseed cake is poisonous, and can be mixed with 1% ferrous sulfate and heated to detoxify, accounting for 10% of the diet after detoxification.

Extended information: The fertilizer of rapeseed cake has:

1. It contains high-efficiency beneficial microbial flora that continuously activates nitrogen in the air, decomposes and releases insoluble phosphorus and potassium nutrients, replenishes soil organic matter, and slowly releases nutrients required for crop growth.

2. Improve the physical properties of the soil, keep the soil soft and easy to cultivate. Promote soil aggregate structure, increase soil porosity, and promote root group growth. Increase soil water and fertilizer retention capacity, and reduce leaching loss.

3. Green environmental protection and improve fertilizer efficiency. Fermented organic fertilizer is non-toxic, safe for crops and soil environment, and mixing with inorganic fertilizers also greatly improves the efficiency of chemical fertilizers.

4. The toxic ingredients in rapeseed cake are soluble in water, especially in hot water. The enzymes involved in the cake are also revived for decomposition, and the decomposition products are slowly adsorbed by the soil.

The fermentation method of feeding is sprinkled on the rapeseed cake with fecal water, which can be sprinkled with phosphorus powder to make it even, note: phosphorus powder can also be used without phosphorus powder. Then cover it with nylon paper wrapping, turn it over once a week, turn it twice, and then ferment it for 15 days before you can use it, and teach it under the head of the fruit tree.

Rapeseed cake is a good organic fertilizer, rich in nitrogen, phosphorus and potassium and other nutrients needed by various plants, and the vegetables grown taste good, but it is best to apply the base fertilizer 7 to 15 days in advance, because his nutrient release is relatively slow, but it is best to go to the agricultural store to buy starter culture, use wood chips, or rice husks and the like according to the instructions with a small amount of water fermentation.

Break the cake, pour it into a pool, add three percent of the probiotics, mix well, cover with plastic wrap, let the probiotics grow in the cake, the drier cake is broken, you can add water, spray on it and mix well, grasp it into a ball, let go of the broken spirit, this kind of words, cover with plastic wrap or plastic film, rapeseed cake is a traditional farmhouse fertilizer raw material, fertilizer effect is very good, of course, generally before use, it is generally fermented and rotted before use, so as to ensure safety. or stacked into a trapezoidal type, cover film. After half a month, stir once with a shovel, and stir a total of 2-3 times every 20 days in a row.

Maintain 40-60 moisture so that the material on the edge of the surface can ferment thoroughly when repeated operations.

Rapeseed cake is the residue left after pressing or leaching to remove oil, rapeseed cake is the main cake fertilizer used for agricultural production in the southern region, rapeseed cake is rich in organic matter and nitrogen, and contains a considerable amount of phosphorus, potassium and trace elements, in the past, farmers called fine fertilizer. At the same time, the plant fiber of the vegetable cake is decomposed into a small molecule sugar and carbon source to prevent the formation of carbon dioxide, nitrogen dioxide and ammonia, and reduce side reactions. This is why natural fermentation is not used, because natural fermentation loses many active ingredients and reduces fertility and efficiency.

I packed it in a bag, sprinkled it with plenty of water, and covered it with plastic paper to keep it warm. The temperature is 20 degrees Celsius, and it can be used as base fertilizer for half a month.

Yes, you first need to crush the rapeseed cake and crush it into powder as much as possible. Rapeseed cake is mixed with water, the ratio is rapeseed cake:water = 1:

7. Or water annihilates rapeseed cake, rapeseed cake is in contact with air and water, which is more suitable for fermentation! If it is paste, it can be diluted with water to 1 20 poured! Pay attention to the rapeseed cake and mix well with water!

Generally, it takes about three months, 1Stir together the fermentation soil turns black, 2Rapeseed cake no longer grows white hair, 3

The rapeseed cake fat no longer stinks and has no taste, which means that it is ready.

The first thing you need to do is to crush the rapeseed cake and crush it into powder as much as possible. Rapeseed cake mixed with water, or water annihilated rapeseed cake, rapeseed cake contact with air and water, more suitable for fermentation! If it is paste, it can be diluted with water to 1 20 poured!

Note that the rapeseed cake should be mixed well with water.

OK. Mix the rapeseed cake with water first, and after fermentation for three months, it can be used as fertilizer.

How to grow rapeseed cake as fertilizer to grow vegetables? What to look out for?

Pro, the use of rapeseed cake as fertilizer and vegetable planting methods and precautions are as follows: First crush the rapeseed cake into powder, and then mix it with water in a ratio of 1:7, rapeseed cake contact with air and water is more suitable for fermentation; If it is paste-like when making, it can be diluted with water to 1 20 watered; Rapeseed cake and water are stirred evenly, generally after about three months, the fermentation soil of Shengheyan stirred together turns black, the rapeseed cake no longer grows white hair, the rapeseed cake fertilizer no longer stinks, and there is no taste, which means that it is good; Do not apply too much at a time, apply thin fertilizer frequently, and apply fertilizer once every 20 days or so, depending on the situation.

Rapeseed cake can not be directly fertilized, it needs to be mixed with water, after 3 months of fermentation, to ensure that the fermentation is mature and then used as fertilizer, pay attention to thin fertilizer diligently, if there is no fermentation and maturity, it is easy to produce high temperature in the process of fermentation and decomposition, burning the root system of crops.

First, the use of rapeseed cake fertilizer.

1. Rapeseed cake fertilizer can be used to improve the soil, rapeseed cake is a by-product of rapeseed oil extraction, it contains about 1% phosphorus and more than 35% protein amino acids, is a good organic fertilizer.

2. If rapeseed cake wants to be used as fertilizer, you first need to crush the rapeseed cake, grind it into powder as much as possible, mix the rapeseed cake with water, and the mixing ratio is rapeseed cake: water is 1:7, or immerse the water in the rapeseed cake, when mixing, be sure to let the rapeseed cake and water stir evenly.

3. After the rapeseed cake is mixed with water, it generally takes about three months, and the fermentation soil that is stirred together turns black, the rapeseed cake no longer grows white hair, and the rapeseed cake no longer smells and has no taste, which proves that the fertilizer has been fermented.

4. When using rapeseed cake as fertilizer, the general principle is to apply thin fertilizer frequently, and not to apply too much fertilizer at one time.

5. In addition, do not use unfermented and mature cake fertilizer directly, because rapeseed cake fertilizer is a hot fertilizer, which will produce high temperature in the process of fermentation and decomposition, and it is easy to burn the crop roots around rapeseed cake.

6. Try to avoid misunderstandings in use, so as not to cause damage to plant roots.

2. Characteristics of fertilizer after fermentation of rapeseed cake.

1. Rapeseed cake fertilizer itself has a large number of enzymes, which can directly increase soil enzymes when applied to the soil, and the organic matter in the soil is the substrate for enzymatic action.

2. After applying rapeseed cake in the soil, it can improve the activity of a variety of enzymes in the soil, increase the number of microorganisms beneficial to root growth, and inhibit a variety of soil-borne diseases such as heavy stubble disease and wilt to a certain extent.

3. The organic content of rapeseed cake is 60%-70%, which can effectively improve the level of soil organic matter, increase the content of soil organic matter, enhance the ability of soil water and fertilizer retention, promote the transformation and absorption of nitrogen, phosphorus, potassium and trace elements in the soil, and improve the soil environment.

4. Rapeseed cake is green and environmentally friendly, and the organic fertilizer of fermented rapeseed cake does not have any toxicity, which can improve soil safety and the efficiency of chemical fertilizer use and save production costs.

5. In addition, the fat content of rapeseed cake is relatively high, and it needs to be decomposed in the soil for a period of time before it can be absorbed by crops, so the fertilizer effect time of rapeseed cake fertilizer is also relatively long.

3. Why rapeseed cake needs to be fermented.

1. Rapeseed cake contains a lot of fiber, and direct fertilization will produce a lot of heat energy, which will cause root burning or seed burning, so it must be fermented before use.

2.If it is not fermented or the fermentation is incomplete, it may cause the rapeseed cake to be fermented twice in the soil, resulting in problems such as seedling burning and low germination rate.

How to make compost for rapeseed cake:

1. Preparation: rapeseed cake should be crushed (not too fine to be close to the fineness of sawdust or bran), sawdust or straw powder, and Youbacon organic fertilizer starter agent.

2. Material formula: Auxiliary sawdust can be added in an appropriate amount (no sawdust can be replaced by straw powder, bran, mushroom residue, etc.), and the ratio of rapeseed cake and sawdust is 7:3.

3. Operation steps:

300g of Youbacon organic fertilizer starter can ferment 1 ton of rapeseed cake. First, mix the strain with 5-10 times of corn flour or bran, rice bran, etc., without adding water, evenly dry mix and dilute, and wait for later use.

Mixing: Start by mixing the sawdust and canola cake well. Sprinkle the baking agent while mixing the rapeseed cake to adjust the appropriate moisture, and if it is dry, you can sprinkle some water appropriately.

Pay attention to the moisture of the raw materials must be controlled about 50%, and the method of judging the moisture is: grab a handful of materials, see the watermark but not drip, and the landing can be scattered. Building piles:

To make a fermentation pile, it is generally necessary to be meters high, 2 meters wide, and the total volume is not less than 3 cubic meters. After construction, cover the pile with breathable covering, which should be shaded and protected from rain.

Maintenance: After the fermentation process begins, the temperature can rise to 60 degrees or more in about 1 3 days, and it needs to be turned once, and the fermentation can be completed after a total of 2-3 times. During the fermentation process, it is necessary to replenish water appropriately according to the specific situation.

After fermentation, all the materials are black or black-brown, soft to the touch, fragile, slightly fragrant or fermented, and can be used when cool.

Introduction of fertilizers

All substances that are applied to the soil or sprayed on the aboveground parts of crops can directly or indirectly supply crop nutrients, increase crop yield, improve product quality or improve soil properties and fertilize soil fertility are called fertilizers.

Those fertilizers that directly supply the essential nutrients of crops are called direct fertilizers, while others are mainly used to improve the physical, chemical, and biological properties of the soil, thereby improving the growing conditions of the crops, are called indirect fertilizers.

Precautions for the use of rapeseed cake as organic fertilizer.

Dear, what problems do you need to pay attention to when making organic fertilizer for rapeseed cake? 1. Material moisture control The primary problem with the use of Gymboree fertilizer starter is to control the moisture of the material, the rapeseed cake has a large oil content, and the water content of the rapeseed cake should be adjusted evenly when adjusting the moisture, and the moisture content of the rapeseed cake should be adjusted to between 60-65%, and the method of discrimination is to grasp the water with the fingers but not dripping, and the material moisture should always be paid attention to after the pile starts fermentation, due to the high oil content of the rapeseed cake, the moisture is not easy to adhere to the fermentation process, and the moisture at the top of the fermentation pile is easy to sink. Resulting in low water content at the top and high water content at the bottom, resulting in uneven heating of the fermentation bed, etc., it is necessary to turn over and replenish water to ensure that the material has uniform water content and uniform heating. 2. Initial pile insulation method Due to the low temperature in some areas in winter, the normal reproduction temperature of microorganisms should be above 5 degrees Celsius, such as the general temperature in Northeast Inner Mongolia and other regions is below zero.

3. Moisture control During the overturning of the material pile, the moisture content of the material needs to be observed, if it is too low, warm water should be appropriately added to adjust the water content, so as to ensure that the moisture of the material is within a reasonable range, so as to quickly ferment the organic fertilizer of rapeseed cake.
