Special strawberry composite biological fertilizer as well as preparation method and application thereof

Abstract

The invention relates to a special strawberry composite biological fertilizer as well as a preparation method and application thereof. The special strawberry composite biological fertilizer comprisesthe following components: EDTA-Ca (Ethylene Diamine Tetraacetic Acid), magnesium sulfate heptahydrate, EDTA-Mg, heptahydrate, EDTA-Zn, manganese sulfate monohydrate, EDTA-Mn, boric acid, EDTA-Fe, EDTA-Cu, soybean molasses, polyglutamic acid fermentation broth, chitosan oligosaccharide, algin, compound amino acid, humic acid, bacillus thuringiensis fermentation broth, bacillus megatherium fermentation broth, bacillus mucilaginosus fermentation broth and streptomyces jingyangensis fermentation broth. Through bacterium activation, seed liquid preparation, fermentation culture and compounding, thecomposite biological fertilizer is prepared, the composite biological fertilizer is applied to strawberry planting, and a diluted composite biological fertilizer liquid is sprayed at different growthstages of strawberry respectively. Due to synergetic effects of substances such as inorganic salts, organic matters and microorganisms, long lasting nutrient substances are provided to strawberry crops, absorption of nutrients in soil by plants is promoted, the fertilizer amount is reduced, and the chemical fertilizer cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a special compound biological fertilizer for strawberries and its preparation method and application. Background technique [0002] my country has always been dominated by agriculture. Since the founding of New China, with the development of agricultural science and technology, especially the widespread use of high-concentration urea in the 1970s, although the output of agricultural crops has been expanded in a short period of time, it has made China's land available for planting Fertility is getting lower and lower, and the widespread use of chemical fertilizers has transformed the inorganic nutrient ions such as nitrogen, phosphorus, and potassium that can be absorbed by crops in the soil into insoluble salts, resulting in soil compaction and reduced fertilizer efficiency. Over time, crop yields have been reduced, resulting in High investment and low ...

AI Technical Summary

Problems solved by technology

Therefore, the market demand is gradually increasing, the planting area and area are also expanding, and the food hygiene problems in the production are constantly exposed, which greatly damages people's health, and even causes many diseases.

In strawberry production in my country, the yield is often increased by using pesticides and chemical fertilizers, but the widespread use of chemical fertilizers converts inorganic nutrient ions such as nitrogen, phosphorus, and potassium that can be absorbed by crops in the soil into insoluble salts, resulting in soil compaction and reduced fertilizer efficiency. , reducing crop yields
