Multi-nutrition seedling fermentation fertilizer and preparation method thereof

Abstract

The invention discloses a multi-nutrition seedling fermentation fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 400-450 parts of livestock excretion, 100-120 parts of dried pond sludge powder, 40-50 parts of straw powder, 50-60 parts of rape seed cake, 50-60 parts of soybean cake, 20-25 parts of corn flour, 1-2 parts of sodium selenite, 1-2 parts of boric acid, 3-4 parts of magnesium sulfate, 4-5 parts of zinc sulfate, 1-2 parts of borate, 3-4 parts of sulfur, 6-9 parts of EM (effective microorganism) bactericide, 10-15 parts of soil conditioner, and a proper amount of water. According to the multi-nutrition seedling fermentation fertilizer, livestock excretion, dried pond sludge powder and other natural organic raw materials are adopted as main raw materials and can be conveniently and easily obtained, and domestic waste can be sufficiently applied, so that energy can be recycled, the raw material structure of the fertilizer can be improved, the using proportion of biological organic fertilizer in the fertilizer can be increased, and food safety and eco-environmental safety can be realized. The prepared fertilizer has the advantages of improving soil, increasing utilization of fertilizer, promoting seedling growth and development and the like.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a multi-nutrient seedling fermented fertilizer and a preparation method thereof. Background technique [0002] The use of chemical fertilizers and organic fertilizers to account for 50% each has become an internationally recognized standard for soil sustainable development. However, in my country’s food production, the input of chemical fertilizers and nutrients accounts for about 80% to 90%, and the input of organic fertilizers only accounts for 10% to 20%, which is much lower than the amount of organic fertilizer used in developed countries. The amount of chemical fertilizers used in my country’s land is seriously excessive. Excessive use not only caused a serious decline in soil organic matter, but also caused a series of ecological problems such as soil compaction, salinization, and water eutrophication, which seriously affected my country's food security and ecological securit...

Problems solved by technology

However, in my country's grain production, the nutrient input of chemical fertilizers accounts for about 80%-90%, and the nutrient input of organic fertilizers only accounts for 10%-20%, which is much lower than the amount of organic fertilizer used in developed countries. The amount of chemical fertilizer used in my country's land is seriously excessive. Excessive use not only caused a serious decline in soil organic matter, but also caused a series of ecological problems such as soil compaction, salinization, and water eutrophication, which seriously affected my country's food security and ecological security.
