Humic acid plant growth nutritional efficient solid fertilizer and preparation method thereof

Abstract

The invention relates to the technical field of fertilizer preparation, and discloses a humic acid plant growth nutritional and efficient solid fertilizer. The humic acid plant growth nutritional andefficient solid fertilizer comprises the following raw materials in parts by weight: 30-50 parts of active humic acid, 2-8 parts of potassium hydroxide, 30-40 parts of an inorganic fertilizer, 30-40 parts of an organic fertilizer, 2-8 parts of a trace element fertilizer, 2-8 parts of a microbial agent, 8-20 parts of a hydrophilic monomer, 3-6 parts of an activator, 3-6 parts of a catalytic oxidantand 1-2 parts of a buffer agent. The invention relates to the humic acid plant growth nutritional and efficient solid fertilizer and a preparation method thereof. The preparation method comprises following steps: adding active humic acid and potassium hydroxide into a mixture II; the obtained compound fertilizer containing the active humic acid is suitable for the growth of crops, can reduce water loss and evaporation, relieve drought pressure, preserve fertilizer, reduce the use of chemical fertilizer, reduce saline-alkali damage, improve soil fertility, improve crop growth and enhance croproot activity under the condition of reducing the use amount of the chemical fertilizer or gradually replacing the chemical fertilizer, so that nutrients in soil can be efficiently and quickly absorbed.

Description

technical field

[0001] The invention relates to the technical field of fertilizer preparation, in particular to a humic acid high-efficiency solid fertilizer for plant growth nutrition and a preparation method thereof. Background technique

[0002] At present, since the fertilizers for crops, vegetables, fruit trees and other plants are mainly based on chemical fertilizers, mixed fertilizers, multi-component micro-fertilizers and solid special fertilizers, such fertilizers are made by mixing various trace elements and macro elements through mechanical equipment, which is not conducive to field At the same time, due to the long-term and large-scale application of chemical fertilizers, the comprehensive index of the soil will decrease, the alkalinity will increase, the soil will be compacted, and the soil fertility will be weakened, resulting in a decline in crop quality and poor taste of various fruits; harmful substances in the soil The retention of chemical fertilizers (esp...
