Abstract

The invention discloses a rice slow-release fertilizer and a preparation method thereof. The rice slow-release fertilizer comprises the following raw material components by weight: 25-40 parts of compound bacteria, 500-600 parts of an organic material, 800-1200 parts of an inorganic material, 100-150 parts of a fertilizer core, 20-30 parts of trace elements, 120-150 parts of additives, 70-80 partsof cellulose and 2500-3500 parts of a solvent.

Description

technical field [0001] The invention belongs to the technical field of materials, and mainly relates to a slow-release fertilizer for rice and a preparation method thereof. Background technique [0002] my country is a large agricultural country, with an annual output of about 700 million tons of straw, which is an economically available raw material for agricultural waste. At present, my country's straw utilization technology is very backward. Except for papermaking, there is no efficient, economical, practical and feasible high-efficiency comprehensive utilization technology. Most of the straw is used for incineration. This extensive utilization method not only wastes precious resources, but also causes serious environmental problems such as smog. Straw, such as wheat straw, is mainly composed of cellulose, hemicellulose, lignin and other substances, which are very difficult to degrade. At present, although it has been reported in the literature that furan compounds can ...
