Abstract

The invention discloses a preparation method of a soil-improving slow-release fertilizer applied to rice. The method comprises the following steps: uniformly mixing rotten chicken manure, fermented slaughter house waste, canal mud, tea seed meal, humic acid, flyash, montmorillonite, bamboo powder, bactericidal deodorant and EM microbial agent, adding water, adding a fertilizer-retention compound,uniformly mixing, drying, crushing, granulating and drying to obtain the soil-improving slow-release fertilizer applied to rice. The fertilizer-retention compound is prepared by the following processes: uniformly mixing p-aminophenyl trimethoxysilane, lauryl sodium sulfate and water, adjusting the pH value of the system to be 4-4.8, stirring, filtering, washing, centrifuging, drying, adding tetrahydrofuran and uniformly stirring, adding succinic anhydride, stirring, precipitating, filtering, washing, drying, adding polyethylene glycol 600, uniformly mixing, adjusting the pH value of the systemto be 3-3.8, stirring, centrifuging, filtering, washing and vacuum drying to obtain the fertilizer-retention compound.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for preparing a rice slow-release fertilizer for improving soil. Background technique [0002] The husks of paddy rice become rice or rice. Nearly half of the world's population uses rice as food, 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. Its core is to establish and restore a virtuous cycle of agricultural ecosystems to maintain the sustainable development of agriculture. In the cultivation of organic rice, continuous cultivation will easily cause soil compaction. affect rice quality and yield. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a preparation method of rice slow-release fertilizer for improving soil. The slow-release fertilizer obtained can improve ...
