Advantages and disadvantages of Doubai organic fertilizer???

1. Rich in organic matter and amino acids, it can promote the formation of soil aggregate structure, improve soil, fertilize soil fertility, improve soil water and fertilizer retention performance, and maintain the possible production capacity of soil.

2. Complete nutrients, long fertilizer effect, can coordinate soil nutrients and balance, promote the development of fruit tree roots, plant growth is robust, green sprouting, flowering and ripening, flower and fruit preservation, improve flowering and fruit setting rate, and prevent premature aging.

3. It contains a large number of beneficial bacteria and their secreted bioactive substances, which can optimize the soil microbial community, inhibit the harm of pathogenic bacteria, increase the number of beneficial bacteria in the soil and rhizosphere, and effectively inhibit the occurrence of diseases such as ring disease, root rot and dry rot of fruit trees.

4. It is conducive to improving the photosynthesis of crops, enhancing the resistance of crops to diseases, heavy crops, insects and other stresses, and has the effects of phosphorus, potassium and nitrogen fixation.

5. Improve crop yield, increase the content of reducing sugar and vitamins in fruits, improve fruit quality, and enhance the storability of fruits.

Dosage. How to use: as base fertilizer, furrow application, and hole application.

It is unscientific to make organic fertilizer only from soybean meal, because the nutrients contained in soybean meal are insufficient, and other things need to be added to the organic species, the most common is to add human and animal manure. And the traditional way of rotting can no longer be used, and it is recommended to use the method of microbial fermentation. Briefly tell you how to make it, and if you have any other questions, you can ask me.

Ratio: grain bran, weeds, human, livestock, poultry manure, crop straw (chopped), stems and leaves, sawdust and sawdust, edible fungus substrate residue and soybean meal, etc. Prepare 200 kg of materials and 1 kg of Nong Shengle planting mushroom liquid, briefly tell you how to make it, if you have any other questions, you can have a detailed understanding of it in Chanong Shengle.

Operating procedures: Prepare 200 kg of fermentation raw materials according to the ratio, which is the fermentation raw materials for use;

Pour 1 kilogram of Nongshengle planting mushroom solution into 50 kilograms of water to dilute and stir evenly, the dilution water is best for well water or river water, if it is tap water, please leave it for 24 hours before use; It is better to be able to properly dissolve some brown sugar in it.

If you have a mixer: you can mix the fermentation raw materials for 2 minutes, and then pour in the dilution of the starter and stir for 6 minutes; No mixer: stir with a shovel according to the principle of less to more, that is, first pour the bacterial liquid dilution into a small amount of fermentation raw materials and stir evenly until there are no lumps, and then pour a small amount of stirred fermented raw materials into the remaining fermentation raw materials and stir evenly until there are no lumps; (Note:.)

Depending on the degree of dryness and wetness of the fermentation raw materials, increase or decrease the amount of water used for dilution, the diluted bacterial solution should be about 40% of the fermentation raw materials, and mix into a ball with your hands, and see the water between your fingers but not dripping water droplets. Note: More water is easy to acid, less fermentation impermeable.

If the fermentation raw material is wet, the amount of water used for dilution should be reduced. ）

Put the mixed fermentation raw materials into a plastic container or cement pool (or a plastic film for soil pit pads), and finally fill it with compaction, seal it with plastic film after discharging the air, it must be completely sealed, the suitable temperature is 25-35, and the fermentation is 5-10 days (generally 4 days in summer, 7 days in spring and autumn, and 10 days in winter), pay attention to the temperature and time to master, until there is no odor containing the smell of wine, that is, the fermentation is successful.

Fermentation Method:

Raw materials: 1000 kg of wet bean dregs, 50 kg of wheat bran (corn flour or bran, etc.), 2 kg of brown sugar. 4 kg of Nongshengle feed fermentation broth.

Operation steps: 1. First dilute 4 kg of feed fermentation broth with 20 kg of water. Then mix well with 50 kg of wheat bran, and the humidity is about 50% (judging standard, grab a handful with your hands, hold it hard to form a lump, and hold it hard, and it feels wet between your fingers, but no water drips down).

2. Melt brown sugar with about 100 kg of water (the specific amount of water consumption depends on the dryness and humidity of the bean dregs).

3. Then sprinkle the mixed wheat bran evenly in 1000 kg of bean dregs, sprinkle it again, spray the brown sugar water that has melted it again, (if possible, you can use a mixer to stir, and it is completely okay to stir it manually).

4. After stirring evenly, put it in a sealed container (woven bag, tank, barrel, fermentation tank, etc.) and compact and seal it for fermentation for 3 to 5 days. You can try to ferment tofu residue with Nongshengle feed fermentation liquid.

4. Enhance the disease resistance of crops, increase the content of reducing sugar and vitamins in fruits.

Expert: The decomposition of organic fertilizer means that the organic fertilizer is compiled, and it changes from raw manure to mature manure. Its essence is that in the process of stacking, through the action of microorganisms, the organic matter that is difficult to be used by crops is turned into nutrients that are easy to be absorbed and utilized by crops, so as to achieve effectiveness; The 60 70 high temperature produced in the pile can kill most of the germs and insect eggs, and achieve harmlessness.

During my production inspection, I found that many vegetable farmers and fruit farmers directly applied unrotted organic fertilizer to the ground and burned seedlings and were infected with pests and diseases.

Expert: First of all, it is necessary to create suitable conditions for the fermentation of microorganisms, in addition to the proper combination of manure and straw in the compost, and maintain suitable moisture, special attention should be paid to the aeration conditions of the compost. Take compost as an example, if you are not in a hurry to use fertilizer, you can press the compost tightly, and it can be semi-decomposed in 2 or 3 months, and it can be completely decomposed after 6 months.

If you are in a hurry to use fertilizer, you can loosen the accumulation, due to good aeration, it can be decomposed in a short time, and produce a high temperature of 60 70, almost all the eggs of the germs will be killed, but the loss of organic matter and nitrogen is larger. The best way is to alternate elasticity, first loosen and pile up for a few days, wait for the high temperature to kill the germs and eggs, and then press the compost pile, and seal the pile to keep warm and rainproof. In this way, it can be semi-rotted after 1 or 2 months, and it can be rotted in 4 or 5 months.

Since there is a time process for decomposing, it is necessary to decompose as early as possible before application, and prepare the organic fertilizer; Especially for greenhouse vegetables, there is often only 1 2 weeks of space time between stubbles. For northern field crops, after the autumn harvest, semi-rotted organic fertilizer can also be applied to the ground in combination with autumn ploughing, and continue to rot in the field.

Expert: The basic principle of rational application of organic fertilizer is to combine it with inorganic fertilizer, mainly as basal fertilizer. The following focuses on the amount of fertilizer applied for the purpose of fertilizer preparation.

Considering the rationality and possibility, it is advocated to apply 1000 3000 kg of decomposed organic fertilizer per mu to field crops; Organic fertilizer must be applied to vegetables and fruit trees, 3,000 4,000 kg per mu of fruit trees and open-field vegetables, and 5,000 7,000 kg per mu of greenhouse vegetables. If it is chicken manure, the amount can be appropriately reduced, and the cake fertilizer is less, 50 150 kg per mu.
