Fertilizer added with perlite, and preparation method thereof

Abstract

The invention discloses fertilizer added with perlite, and a preparation method thereof. The fertilizer is prepared from the following raw materials by weight: 35-50 parts of perlite, 65-75 parts of urea, 50-80 parts of monoammonium phosphate powder, 45-60 parts of potassium chloride, 15-20 parts of zinc sulfate, 5-7 parts of polyacrylamide, 4-6 parts of sodium lignin sulfonate, 10-12 parts of attapulgite powder, 200-300 parts of straws, 150-200 parts of livestock manure, 20-30 parts of phosphorite powder and 10-12 parts of a soil activator. A soil conditioner provided by the invention comprises a jade component which contains a lot of microelements and is beneficial to human body, can effectively absorb and solidify toxic heavy metal elements in the soil, reduce absorption of the heave metal elements by the crop, and can increase crop output. High adsorbability of the perlite enables three main elements required by a plant to release slowly, can improve soil crust, and increase soil loose permeability and capacity of retaining water and fertilizer. A production process has no three wastes (waste gas, waste water and industrial residue).

Description

Technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a fertilizer added with perlite and a preparation method thereof. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industries. 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 serious problems of population increase and environmental degradation. As a populous country and a large agricultural country, this problem is particularly prominent. One of the main reasons for this situation is the massive use of inorganic fertilizers. The shortcomings of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide crops with comprehensive and reasonable nutrients; 2. The soil is acidified or salinized after use, which reduces the soil quality; 3. , Due to the d...

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
