Biological compound fertilizer containing organic and inorganic components and preparation method thereof

Abstract

The invention discloses biological compound fertilizer containing organic and inorganic components and a preparation method thereof. The compound fertilizer comprises beneficial microorganism flora, organic matter, humic acid and inorganic nutrient. The preparation method comprises the following steps of: grinding the raw materials including 50-60% of organic matter, 5-10% of humic acid and 20-40% of inorganic nutrient by a grinder into powder of 80-120 meshes; putting 50-100 million beneficial bacteria per gram of product into a mixer, uniformly mixing and feeding into a granulator for granulation; drying, cooling and screening; and finally packing to obtain a finished product, wherein organic matter accounts for 20-30%, and humic acid accounts for 3-5%; in the inorganic nutrient, major elements account for 15-25%, the secondary elements account for 5-10%, and the trace elements account for 1-2%; and each gram of the finished product contains 30-50 million beneficial bacteria. The fertilizer disclosed by the invention is suitable for any crop; the fertilizing experiments of the fertilizer are conducted on paddy rice, cotton, rape, melon and fruit, wheat and vegetables; and the results show that: the yield of the experimental group is increased by 15-30% over the control group without using the fertilizer, and the yield increasing effect is obvious.

Description

technical field [0001] The invention relates to a biological compound fertilizer containing organic and inorganic components and a preparation method thereof, which belongs to the category of high-tech full-nutrition crop fertilizers. Background technique [0002] As we all know, the development of scientific fertilization technology in the world has gone through three stages: one is the scientific fertilization period from 1843 to the middle of the 20th century, with the goal of yield as the goal; the other is the period from the middle of the 20th century to the 1980s, with the goal of yield and quality The period of scientific fertilization; the third is the period of scientific fertilization aimed at yield, quality and ecology since the 1990s. Through this development process, people have gradually gained a deep and comprehensive understanding of the positive and negative effects of fertilizer application: fertilizer is not only the material basis for high-yield and high...

AI Technical Summary

Problems solved by technology

Chemical fertilizers are generally simple fertilizers. After being applied to the soil, the original nutrient balance of the soil will be broken. Excessive application for a long time without supplementing organic matter will cause excessive consumption of soil organic matter, and the imbalance of nutrient ratio will in turn affect the fertilizer efficiency of chemical fertilizers.

Second, the abnormal environment of the farmland is destroyed

Third, soil physical and chemical properties deteriorate

Long-term application of chemical fertilizers will reduce soil organic matter, reduce aggregate structure performance, aggravate soil compaction, and reduce fertilizer and water retention capacity

Fourth, soil microbiota are disrupted

Fifth, the quality of agricultural products has declined

The fertilization effect of chemical fertilizers is relatively fast, which has a significant effect on the growth of crops in the early stage, but is not conducive to the accumulation of crop nutrients. Some substances of chemical fertilizers are absorbed and accumulated in plants by crops, thus affecting the quality of agricultural products.
