Abstract

The invention discloses a method for preparing special paddy rice fertilizers with increased fertilizer utilization rates. The method includes steps of uniformly mixing ammonium nitrate, calcium triple superphosphate, precipitated phosphorus fertilizers, calcium magnesium phosphate, tri-nitric acid hexa-urea iron compounds, borax, rectorite, mica powder, zeolite powder and medical stone powder with one another to obtain mixed materials; uniformly mixing biogas residues, seaweed powder, fermented oil residues, sunflower seed meal, palm meal, fishbone meal and pig manure with one another to obtain first mixtures, adjusting the water content of the first mixtures, grinding the first mixtures, adding the mixed materials into the first mixtures, uniformly mixing the mixed materials and the first mixtures with one another to obtain second mixtures, irradiating the second mixtures by ultraviolet lamps, carrying out homogeneity treatment on the second mixtures, adding pectinase into the secondmixtures to carry out enzymatic hydrolysis on the second mixtures, adding bacillus subtilis into the second mixtures to carry out anaerobic fermentation on the second mixtures, adding composite enveloping agents into the second mixtures to obtain third mixtures, carrying out granulation and carrying out drying and cooling to obtain the special paddy rice fertilizers with the increased fertilizerutilization rates.

Description

technical field [0001] The invention relates to the technical field of special fertilizer for rice, in particular to a preparation method of special fertilizer for rice that improves the utilization rate of fertilizer. Background technique [0002] Rice is a fibrous root system with well-developed adventitious roots. The ears are panicles and self-pollinating. It is an annual cultivated grain with erect stems and a height of 30-100 cm. The above is one of the main food crops. At present, in order to increase rice yield, a large amount of chemical fertilizers are applied. Long-term application of chemical fertilizers has led to negative problems such as soil structure damage, water pollution, and fertilizer utilization rate decline, which need to be resolved urgently. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a method for preparing special fertilizer for rice that improves the utilization...
