High efficiency gradient dissolution and release fertilizer and production method

Abstract

The invention discloses a high-efficient gradient dissolving and releasing fertilizer and a manufacturing method thereof. The dissolving and releasing fertilizer is characterized in that the structure of the dissolving and releasing fertilizer comprises a prophase fertilizer, a metaphase fertilizer, an anaphase fertilizer suitable for the prophase growth, the metaphase growth and the anaphase growth of crops; the anaphase fertilizer is spherical particles; and the outside of anaphase fertilizer particles is sequentially wrapped with obstruction slurry, the metaphase fertilizer, obstruction slurry, the prophase fertilizer and obstruction slurry. According to the practice of planting beneficial crops in a stony desertification region and the characteristics of growth and development of commericial crops, in particular the characteristics of distribution of a root system; the prophase fertilizer nutrient, the metaphase fertilizer nutrient and the anaphase fertilizer nutrient needed by the crops are manufactured into the dissolving and releasing fertilizer which can be gradually released by gradient and can guarantee the requirement of the whole growth and development of the crops, thereby reducing labor intensity, improving utilization rate of the fertilizer and reducing pollution to environment. The obstruction slurry is totally manufactured through adopting natural and harmless materials and does not generate possible influence on or harms to environment as the chemical material composition adopted in the prior slow release fertilizer.

Description

technical field [0001] The invention relates to a high-efficiency gradient dissolution-release fertilizer and a production method thereof, in particular to a high-efficiency gradient dissolution-release fertilizer that gradually releases fertilizer nutrients according to the nutritional requirements required by the growth and development stages of crops. Background technique [0002] In modern agricultural production, it is necessary to continuously apply fertilizers to crops to achieve high-yield and high-quality crops, so as to meet the growing demand of the world's population for crops (especially food crops, economic crops, etc.). Due to the low level of agricultural production in our country, the ability to use scientific and technological means to solve problems in agricultural production is not high enough, and the effective utilization rate of a large amount of fertilization applied to the soil is generally low, which not only causes waste of fertilizers, but also aff...

Problems solved by technology

Due to the low level of agricultural production in our country, the ability to use scientific and technological means to solve problems in agricultural production is not high enough, and the effective utilization rate of a large amount of fertilization applied to the soil is generally low, which not only causes waste of fertilizers, but also affects the environment. Pollution

Especially in rocky desertification mountainous areas, under the conditions of thin soil, steep slopes, and heavy rainfall, the nutrients of ordinary fertilizers used can easily move with water and seep into the ground, while crops cannot absorb and utilize them, resulting in waste. Contamination of ground or surface water
