Compound fertilizer with soil activator and preparation method thereof

Abstract

The invention discloses a compound fertilizer with a soil activator and a preparation method thereof. The compound fertilizer is characterized by being prepared from the following components in parts by weight: 65-75 parts of urea, 30-50 parts of monoammonium phosphate, 35-45 parts of potassium chloride, 10-15 parts of zinc sulfate, 100-120 parts of brown coal, 100-150 parts of saw dust, 20-30 parts of zeolite, 60-75 parts of ammonium dihydrogen phosphate, 5-10 parts of humic acid, 40-50 parts of rapeseed dregs, 20-25 parts of potassium dihydrogen phosphate, 30-40 parts of sodium chloride, 10-15 parts of carboxymethylcellulose and 15-25 parts of the soil activator. The soil activator disclosed by the invention contains a jade component which contains a lot of trace elements beneficial for a human body. Meanwhile, the soil activator can effectively adsorb and solidify toxic heavy metal elements in soil and can improve the crop output. The compound fertilizer disclosed by the invention is reasonable in formula and low in cost, adopts a scientific and practical production process, and can increase organic matters of soil, adjust the ph value of soil and alleviate the poor conditions such as hardening and poor ventilation of soil.

Description

technical field [0001] The invention relates to a compound fertilizer and a preparation method thereof, in particular to a compound fertilizer added with a soil activator and a preparation method thereof. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing severe problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is particularly prominent. One of the main reasons for this situation is the extensive use of inorganic fertilizers. The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized,...

AI Technical Summary

Problems solved by technology

The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce the soil quality; 3. 1. Due to the decline of soil quality, the buffering capacity is greatly reduced, and the use of inorganic fertilizers is difficult to achieve results and is likely to cause fertilizer damage; 4. Due to the imbalance of nutrients, the disease resistance of the crops used is reduced; 5. During the production and use of inorganic fertilizers, there will be The environment causes a lot of pollution and wastes a lot of resources; 6. It makes agricultural production fall into a vicious circle and it is difficult to achieve sustainable development

At present, although the existing soil-improving fertilizers can play a role in improving the soil, these fertilizers have poor air permeability and fermentation and decomposition capabilities, and cannot effectively decompose various naturally occurring fibers and some artificially synthesized chemical substances. Not long-lasting, crops absorb less nutrients from fertilizers, and fertilizer use efficiency is low
