Special organic compound fertilizer for rice and preparation method thereof

Abstract

The invention discloses special organic compound fertilizer for rice and a preparation method thereof. The organic compound fertilizer comprises the following components which are mixed in parts by weight: rape straw, rapeseed cake, human human excreta, coal ash, sawdust, peat, realgar, mixed bacterias, sweet potato stems, dry reed, biochar, biological black coal, hawthorn pulp, pagoda tree flowerresidue, crab shell, animal dung, EM strain, urea, potassium chloride, calcium nitrate, silicate, yellow phosphorus slag, monoammonium phosphate, dicyandiamide, urea formaldehyde, borax, zeolite mineral powder and biogas residue; the preparation method comprises the following steps: preparing a mixture, preparing an organic mixture, pelleting, cooling and bagging. The organic compound fertilizernot only can improve the soil fertility of rice field, improve the soil environment of rice field and effectively control the occurrence of rice diseases, but also is beneficial to the improvement ofrice yield and quality improvement, improves the use efficiency of nutrient resources, coordinates the nutrient balance of soil, and is beneficial to improvement of soil fertility and realization of successive high yield of rice.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a special organic compound fertilizer for rice and a preparation method thereof. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Originally produced in China, rice was planted in the Yangtze River Basin of China seven thousand years ago. Rice in the broad sense is different from upland rice; rice in the narrow sense refers to fresh rice, which is different from sea rice. According to the type of rice, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. There are other classifications, rice is generally cultivated in paddy fields, and water rice is cultivated without soil. Rice is generally less than one meter high, and those about 2 meters are newly cultivated giant rice. And rice needs to...
