Bio-compound water-retaining fertilizer

Abstract

The invention discloses a bio-compound water-retaining fertilizer which is characterized by comprising 8-10 percent of bio-organic fertilizer, 10-20 percent of weathered coal, 5-15 percent of grass carbon, 3-5 percent of nitrogen-fixing bacteria, 3-5 percent of phosphorus bacteria, 3-5 percent of potassium bacteria, 1-3 percent of lauryl alcohol ethoxy ammonium sulfate, 2-4 percent of compound biological bacteria, 3-5 percent of humic acid, 1-3 percent of zeolite powder, 1-3 percent of bentonite, 3-5 percent of chitin, 1-3 percent of polypeptide, 5-15 percent of algae fertilizer, 10-20 percent of monopotassium phosphate and 5-7 percent of water-retaining agent. The bio-compound water-retaining fertilizer has the beneficial effects of decomposing organic pollutants, effectively improving the crop capability of absorbing nutrition components, reducing the waste of fertilizers and reducing the damage of chemical fertilizers to soil, so that nutrition balance is achieved, the nutrients needed by the growth of crop are met and the function of retaining water can be achieved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a biological composite water-retaining fertilizer. Background technique [0002] With the continuous development of economy and society, the problem of soil degradation has become increasingly prominent, mainly manifested as soil compaction and hardening, erosion, salinization, acidification, element imbalance, chemical pollution, loss of organic matter and degradation of flora and fauna, etc., serious The development of land productivity is restricted. At present, common chemical fertilizers have a single nutrient distribution ratio, low fertilizer utilization rate, and increased heavy metals and toxic elements. Agricultural investment increases year by year. In the west of my country, especially in the desert areas, there is generally drought and water shortage. Even if it rains occasionally, it will be lost quickly. Contents of the invention [0003] The purpose of the present ...
