Modified fertilizer special for paddy rice

Abstract

A disclosed modified fertilizer special for paddy rice is prepared from the following raw materials in parts by weight: 5-10 parts of coal stove ash, 15-20 parts of waste vegetable leaves, 6-12 parts of bamboo charcoal, 20-30 parts of animal manure, 10-18 parts of Ipomoea batatas leaves, 8-16 parts of humic acid, 3-6 parts of diatomite, 11-17 parts of urea, 4-8 parts of Chinese medical stone, 6-9 parts of biological bacteria, 20-30 parts of ammonium bicarbonate, 8-16 parts of potassium chloride, 5-8 parts of tung oil, 4-7 parts of paraffin, 4-7 parts of calcium carbonate, 2-5 parts of iron ore, 15-30 parts of calcium superphosphate and 3-6 parts of zinc phosphate. The provided modified fertilizer special for paddy rice is reasonable in formula, relatively comprehensive and balanced in nutrition, strong in pertinency, good in effect and obvious in effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an improved special fertilizer for rice. Background technique [0002] my country is a large agricultural country. Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. . There are many types of fertilizers currently used for hybrid rice cultivation, among which the special fertilizer for hybrid rice mostly adopts NPK compound fertilizer available on the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth of hybrid rice in a short time need. However, long-term use will damage the soil aggregate structure, easily cause soil compaction and soil hardening, thereby affecting the ...

AI Technical Summary

Problems solved by technology

However, long-term use will destroy the soil aggregate structure, easily cause soil compaction and soil hardening, thus affecting the growth of hybrid rice, and the promotion effect on hybrid rice growth is not obvious

At the same time, although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, hybrid rice absorbs slowly, and the fertilizer efficiency is low, and the effective balance between various effective nutrients cannot be achieved.
