Straw carbon matrix biological organic fertilizer and preparing method

Abstract

The invention discloses a straw carbon matrix biological organic fertilizer and a preparing method. China is the largest fertilizer importing country and the largest nitrogenous fertilizer producing country in the world, and has 7% of arable land on earth, but usage amount of fertilizers and pesticides is 35% of global total amount, and yearly needed amount of fertilizers are 150,000,000 tons. The utilization ratio of fertilizers in China is only 35%-45%, the balance is fixed or leached by soil, causing environmental problems of water body pollution, lake eutrophication and the like. The straw carbon matrix biological organic fertilizer is prepared from, by weight, 60-70 parts of a compost raw material, 25-30 parts of straw carbon of a microbial agent with an adsorption function, 2-5 parts of zeolite powder, 2-5 parts of bentonite and 0.5-1 part of a binder. The straw carbon matrix biological organic fertilizer is applied to the field of bio-fertilizers and green planting.

Description

[0001] Technical field: [0002] The invention relates to a straw carbon-based biological organic fertilizer and a preparation method. [0003] Background technique: [0004] my country is the world's largest importer of chemical fertilizers and nitrogen fertilizer producer. It owns 7% of the arable land on the earth, but the use of chemical fertilizers and pesticides accounts for 35% of the world's total, with an annual demand of 150 million tons of chemical fertilizers. The utilization rate of chemical fertilizers in my country is only 35% to 40%, and the rest is fixed or leached by soil, causing environmental problems such as water pollution and lake eutrophication. With the rapid development of my country's agricultural industrialization, the continuous transformation of the breeding model, and the growing separation of the planting and breeding industry, a large number of livestock and poultry manure and crop straws have been piled up, which not only pollutes the ecologica...

Problems solved by technology

The utilization rate of chemical fertilizers in my country is only 35% to 40%, and the rest is fixed or leached by the soil, causing environmental problems such as water pollution and lake eutrophication.

With the rapid development of my country's agricultural industrialization, the continuous transformation of breeding models, and the growing separation of farming and breeding industries, a large number of livestock and poultry manure and crop straws have been piled up, which not only pollutes the ecological environment of surrounding areas, but also causes serious damage. waste of resources
