Compound fertilizer for promoting increase of yield and quality of organic rice

Abstract

The invention discloses a compound fertilizer for promoting increase of the yield and quality of organic rice. The compound fertilizer comprises the raw materials in parts by weight: 20-35 parts of ammonium chloride, 4-12 parts of a kiln ash potash fertilizer, 10-20 parts of ground phosphate rock, 40-80 parts of an organic fertilizer, 0.1-0.2 part of EDTA chelated manganese, 0.2-0.4 part of iron hexaurea trinitrate, 6-10 parts of a slow-release agent and 1-3 parts of ultra-fine toughening powder. The ultrafine toughening powder is prepared by the following processes: mixing silica hydrogel, dodecyl trimethyl ammonium bromide, fatty alcohol-polyoxyethylene ether and water evenly, then adding oxidized polyethylene wax, an ionic emulsifier and sodium pyrosulfite, mixing, introducing nitrogengas and pressurizing in a sealed state, heating, stirring, discharging, cooling, adding octadecyltrimethoxysilane in a stirring state, continuing to stir, and filtering to obtain ultra-fine toughenedpowder. The compound fertilizer can improve the quality of rice, reforms the structure of soil aggregates, makes soil looser, prevents soil hardening and raises soil fertility.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a compound fertilizer for improving the yield and quality of organic rice. Background technique [0002] Rice is obtained from the hulled rice grains. Nearly half of the world's population eats rice, including almost the entire population of East Asia and Southeast Asia. At present, organic rice will be the main direction of rice planting in the future, and its core is to establish and restore a virtuous circle of agricultural ecosystems to maintain the sustainable development of agriculture. In the cultivation of organic rice, how to increase the yield per unit area of ​​rice and increase the frequency of rice planting is one of the major issues that mankind is facing today. However, at present, a large amount of chemical fertilizers are applied in the process of rice planting, which leads to serious soil compaction, which seriously affects the increase of rice production...
