Special fertilizer for rice

Abstract

A special fertilizer for rice comprises, by weight, 20-30 parts of rapeseed meal, 15-25 parts of slaked lime, 1-3 parts of borax, 6-8 parts of maifan stone, 1-3 parts of potassium, 10-12 parts of plant ash, 1-3 parts of phosphorus, 1-3 parts of zinc sulfate, 6-8 parts of carboxymethyl cellulose, 3-5 parts of nitrogen, and 1-3 parts of biological bacteria. The special fertilizer can provide various nutrition components for growth of rice, has lasting fertilizer effects, can effectively improve the soil structure, and increases the rice output.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for rice. Background technique [0002] In the process of planting rice, chemical fertilizers need to be applied. In the prior art, inorganic fertilizers are mostly used, but long-term use will damage the soil aggregate structure, easily cause soil compaction, and soil hardening, thereby affecting the growth of rice and not promoting the growth of rice. Obviously, at the same time, although pure organic fertilizer is rich in organic matter, the release of nutrients is slow, the absorption of rice is slow, the fertilizer efficiency is low, and the effective balance of various effective nutrients cannot be achieved. In order to solve the above disadvantages, the present invention chooses to mix organic fertilizers and inorganic fertilizers to develop a special fertilizer for rice. The special fertilizer for rice of the present invention can meet the need...
