Rice seedling-stage growth-assissting ammonium nitrogen fertilizer and preparation method thereof

Abstract

The invention discloses a rice seedling-stage growth-assissting ammonium nitrogen fertilizer and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: natural zeolite, diluted HCl with the concentration of 2 mol / L, a NaCl solution with the concentration of 6 wt%, sweet potato residue, vinasse, herbage, turf, pleurotus eryngii residue, EM inocula, shell powder, clay, a seedling-strengthening agent, paclobutrazol, diammonium phosphate, basic zinc sulfate and proper amount of water. the growth vigor of rice at the green-turning stage directly influences tillering of rice at the late stage and the output, and the fertilizer, which is obtained by performing liquid fermentation on vinasse, edible fungus waste residue and the like, filtering for obtaining a filtrate, mixing the filtrate with modified zeolite particle and an ammoniacal nitrogen fertilizer and performing adsorption, possesses sustained release function.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an ammonium nitrogen fertilizer for promoting the growth of rice seedlings and a preparation method thereof. Background technique [0002] Zeolite is the general term for zeolite minerals. So far, more than 40 kinds of natural zeolites have been discovered in the world. The more common ones are analcite, clinoptilolite, laurelite, erionite, chabazite, and mordenite. Zeolites are mainly composed of SiO 2 、Al 2 o 3 、H 2 A silicate mineral composed of four parts of O, alkali metal and alkaline earth metal ions, in which silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons constitute the three-dimensional space frame structure of zeolite, and alkali metals, alkaline earth metals and water molecules are loosely and easily combined. Substitution, so that zeolite has special application performance - adsorption, ion exchange and so on. [0003] Agriculture a...

Problems solved by technology

[0003] Agriculture and planting have now become an important indicator of a country's productivity. In order to improve production efficiency, large-scale agriculture and planting have accelerated production, which often results in the lack of nutrients in the planting land. It is inevitable to abuse chemical fertilizers to increase production. A large amount of fertilizers Using it can indeed increase the yield, but the fertilizer cannot be fully utilized within the time of planting. According to data, more than 30% of the fertilizer components are washed into the soil and rivers by rain, causing serious pollution.
