Moisture and fertility preserving straw fertilizer

Abstract

The invention discloses moisture and fertility preserving straw fertilizer, which is prepared from the following raw materials in parts by weight: 60 to 100 parts of human and animal excreta, 40 to 80 parts of wheat straw, 30 to 50 parts of silkworm excrement, 20 to 40 parts of vetch, 8 to 16 parts of peanut vine, 14 to 22 parts of vinasse, 6 to 14 parts of manioc waste, 6 to 12 parts of fermented chicken manure, 15 to 25 parts of cottonseed cake, 0.2 to 0.6 part of bacillus subtilis, 0.4 to 0.8 part of phytase, 4 to 8 parts of modified hydroxyapatite, 1 to 3 parts of grass carbon, 4 to 8 parts of briquette residue, 2 to 4 parts of talcum powder, 3 to 5 parts of borax, 20 to 28 parts of phosphate ore powder, 15 to 25 parts of kiln ash potassium fertilizer, 10 to 18 parts of monopotassium phosphate, 40 to 70 parts of urea, 0.3 to 0.9 part of sodium molybdate and 0.6 to 1.4 parts of zinc ammonium phosphate. According to the moisture and fertility preserving straw fertilizer, slow-release effects on nutrient substances are extremely good; the effect of ameliorating soil is obvious; the efficiency and the benefit of comprehensively utilizing straw are improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water- and fertilizer-retaining straw fertilizer. Background technique [0002] From the perspective of foreign countries, especially in developed countries, through scientific and technological progress and innovation, a variety of uses have been found for the comprehensive development and utilization of crop straw. New approaches such as vaporization, straw power generation, straw ethanol, and straw building materials have greatly improved the utilization value and utilization rate of straw, which are worth learning from. At present, wheat straw is burned the most in my country, and there is still a problem with wheat straw, that is, even if wheat straw is transported out of the field, farmers will pile it into ditches, rivers, etc. The water will turn yellow and cause water pollution, so there is an urgent need to properly dispose of wheat straw.
