What is bio-organic fertilizer? Hurry up, don’t be fooled again.

China only needs one-fifth of the world's arable land to feed one-fifth of the world's population. Increasing the output per unit area and meeting the demand for increasing food is the need for sustainable agricultural development. On the other hand, in order to pursue production, the large-scale use of chemical fertilizers has exposed many problems of soil and poor quality of agricultural products. Therefore, changing the fertilization method is a necessary way for the sound development of agriculture. On the road of improving soil and increasing efficiency, "bio-organic fertilizer" has gradually entered our sight. Today we will take a look at some things about bio-organic fertilizer!

1 1: Basic concepts and principles of bio-organic fertilizer!

Bio-organic fertilizer: refers to a kind of fertilizer that combines microbial fertilizer and organic fertilizer effect with specific functional microorganisms and organic materials mainly derived from animal and plant residues and treated by harmless treatment and fermented fermentation.

Its specific functional microorganisms refer to:

1. It can utilize the organic matter in the soil as the carbon source, the nitrogen dioxide in the air as the nitrogen, and the nitrogen-fixing bacteria which grow and multiply in large quantities;

2. It can decompose phosphate-dissolving bacteria and potassium-dissolving bacteria which are fixed in soil or soil parent material;

3. A beneficial bacteria capable of antagonizing the growth and reproduction of soil-borne pathogens.

Principle: Bio-organic fertilizer generally contains a certain amount of functional microorganisms per gram. After being applied to the soil, under the suitable conditions of ground temperature of 25-35 ° C, pH value of 5.5-8.5, soil water holding capacity of 50-70%, and no biocide residue, Its nitrogen-fixing bacteria, phosphate-dissolving bacteria, potassium-dissolving bacteria and anti-pathogenic bacteria have been propagated for about 20 minutes, showing a geometric progression. Each beneficial bacteria is a source of fat. The growth and reproduction of difficult bacteria that are difficult to count is equivalent to moving the fertilizer production plant to the ground, continuously producing nitrogen, phosphorus, potassium and trace elements for plant absorption and utilization, to increase crop yield. , quality; improve soil, deepen the cultivation layer; reduce the occurrence of pests and diseases.

2 2: Application effect!

1, generally 50 kg of bio-organic fertilizer, can provide 4.3 kg of nitrogen, 2.7 kg of phosphorus, 6.5 kg of potassium.

2, mixed with a sufficient amount of farmyard manure, can completely replace the fertilizer; farmyard fertilizer is not enough, can reduce the amount of fertilizer used to raise seedlings by 30%, the amount of bio-organic fertilizer meets the requirements, and the fertilizer can no longer be used after the seedling is raised.

3. A part of chemical fertilizer application is directly absorbed and utilized by crops. Most of the crops that are urgently absorbed by the crops are absorbed and digested by beneficial bacteria, converted into organic matter, used for plant utilization, reducing the loss of chemical fertilizers, increasing the utilization rate of chemical fertilizers, and increasing the fertilizer efficiency. To reduce the adverse effects of chemical fertilizers on the environment and the quality of agricultural products, and to improve the resistance of plants to pests and diseases, the number of pesticides applied can be reduced by 3 to 4 times throughout the year to improve the quality of crops and sales, which is conducive to product sales.

4. Eliminate soil compaction, improve soil aggregate structure, increase soil permeability, reduce soil loss, increase soil organic matter content, protect the environment, and create a stable and productive soil environment.

5. Bio-organic fertilizer has a sustained and stable fertilizer effect. Maintaining a certain nutritional growth during the fruiting period of crops, achieving both nutrition and reproductive growth, is not only conducive to increasing the annual output of perennial crops, but also can lay the foundation for high yields in the coming year. The annual and small results of crops are not obvious.

6. The crops applying bio-organic fertilizer generally show that the plants grow robustly, the leaf green increases, and the photosynthesis efficiency increases. Strong post-fertilizer effect, crops are not easy to pull, and the harvest period is extended. Increasing production principle: increase the seed setting rate and seed solidity, increase the harvest yield in the later period, and the crop generally increases production by more than 10%.

7, microbial activities can improve the soil early spring temperature, early maturing cultivation and open-air cultivation of greenhouse facilities have the effect of 5 to 7 days in the morning market.

8. The fruit is full and even, the glaze is colored, the aroma is strong, and the appearance attracts the customers; the soluble solid content and the sugar content are generally increased by 1-2 degrees, the softness is increased, and the taste flavor can retain the customer.

3 3: How to use!

Fertilization essentials: seedbed and spread crops, fertilizer application; transplanted hole application or ditch application; top dressing or "well" glyph application; fertilization depth and range within the effective absorption limit of roots, and increase roots as much as possible The area that can be contacted; after fertilization, it must be mixed well in the soil and covered with new soil moisturizing; after fertilization, the wet fertilization site must be poured, and the soil water holding capacity of the fertilization site should be kept for 50-70% for a long time to ensure the microbial activity.

1) Rice and aquatic crops: 40 kg of rice per mu, 100 kg of lotus root, lotus root, etc., combined with deep application of ammonium bicarbonate, when the last plowing field.

2) Annual dry crops and vegetables: 150 kg per mu, mixed with farmyard manure or compound fertilizer (30% less than the conventional dosage).

3) Perennial fruit trees and seedlings: The first planting pits, 15 to 20 kg per plant and farmer fertilizer, phosphate fertilizer, straw, soil mix well; young trees use 2 kg ditch per plant per year; adult trees open every spring Use 3 to 5 kg per plant and mix with farmyard manure or chemical fertilizer. When the fruit is inflated, use 3 to 5 kg per plant and mix with the farmyard manure.

4), seedbed: 100 kg with a small amount of compound fertilizer with farmyard manure and soil mix well.

4 4: Note!

1. Soil pH is best when the pH value is 5.5-8.5, and the pH is too low and too high to adjust the pH value.

2, can not be used with fungicides, physiological acid, physiological alkaline fertilizer,

3, after opening the package, do not put it for a long time, it is best to use it at one time, so as not to reduce the fertilizer effect.

4, soil drought should be timely irrigation, soil organic matter content is too low (<3%) application rate should be doubled.

5, the fertilizer is stored in the dark, shelter from the rain.

6, mixed with fertilizer, should be used now, and mix well with the soil.

7, the optimal temperature for the application of bacterial fertilizer according to soil moisture is 25 ° C ~ 27 ° C, below 5 ° C, above 45 ° C, the application effect is poor. At the same time, it should also be known that the suitable soil moisture of nitrogen-fixing bacteria is about 60%, that is, the moisture of the wet soil is most suitable.
