Problems solved by technology

However, the compound fertilizer described in this patent is formed by mixing two parts of organic fertilizer and slow-release liquid, and most of its components are organic fertilizers. As a slow-release liquid for improving fertilizer efficiency and reducing the frequency of fertilization, the composition is relatively simple, only including Dicyandiamide, phenylphosphamide, diatomaceous earth powder and the rest of the water, the slow release effect of this combination is not obvious

Abstract

A slow-release compound fertilizer used for paddy rice planting and a preparing method thereof are provided. The compound fertilizer comprises core fertilizer particles and a coating layer covering the core fertilizer particles. The compound fertilizer comprises a core fertilizer and the coating layer covering the core fertilizer. The two-layer structure makes a slow-release effect more obvious and a fertilizer effect longer. Topdressing is not needed in a planting process. The core fertilizer is rich in trace elements, thus improving nutrition value of paddy rice. Components of the compound fertilizer are friendly to soil. The compound fertilizer is low in production cost, facilitates market popularization and is good in economic benefit.

Description

technical field [0001] The invention relates to a slow-release compound fertilizer for rice planting and a preparation method thereof. Background technique [0002] Rice (scientific name: Oryza sativa) is a kind of herbaceous Oryza sativa, and it is also the most important and longest food in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 meter high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 cm below the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Generally, the size of the rice ear is 5 to 12 mm long and 2 to 3 mm thick. [0003] About half of the world's people eat rice as a staple food, especially in Asia, where ...
