Organic composite biological fertilizer based on agriculture straw

Abstract

A disclosed organic composite biological fertilizer based on agriculture straw is characterized by comprising the following substances in parts by weight: 25-36 parts of calcium hypophosphite, 100-150 parts of livestock and poultry excrement, 30-50 parts of corn straw, 30-40 parts of beans straw, 20-30 parts of vegetable cake, 1-2 parts of trace elements, 5-9 parts of sodium dihydrogen phosphate, 2-7 parts of disodium hydrogen phosphate, 3-8 parts of sodium polyphosphate and rice bran, 10-16 parts of wheat bran, 1-2 parts of naphthylacetic acid, and 3-8 parts of humic acid. The organic composite biological fertilizer is rich in beneficial microbes, comprehensive and balanced in nutrition and persistent in effect, and is capable of improving the organic matter content in soil.

Description

technical field [0001] The invention relates to an organic compound biological fertilizer based on agricultural stalks. Background technique [0002] Fertilizer is the food of plants, and fertilization is an essential means to ensure high and stable crop yields in the agricultural production process. The fertilizers currently used mainly include single inorganic fertilizers, compound fertilizers and organic-inorganic compound fertilizers. According to statistics, the contribution rate of inorganic fertilizers to grain is about 35%. Although the effect of inorganic fertilizers on increasing grain production is relatively obvious, in recent years, with the increase in the application of inorganic fertilizers, soil structure has been destroyed and organic matter content has declined. unpleasant sight. Organic fertilizers are usually obtained by heaping wastes rich in organic matter, but they have the disadvantages of time-consuming, labor-intensive, pollution and nutrient los...
