Abstract

The invention relates to a microcapsule soil conditioner and a preparation method thereof, and the preparation method comprises the following steps: preparing a mixed solution containing nutrient substances and capsule forming raw materials, and treating the mixed solution by a spray drying method to obtain the microcapsule soil conditioner. Compared with the prior art, the soil conditioner with the microcapsule structure is prepared by taking natural source macromolecules as a coating material and loading nutrient substances required by soil treatment and plant growth; and through coating of natural source macromolecules, the release period of nutrient substances can be effectively prolonged, the use efficiency of effective components is improved, and the fertilizer has a wide application prospect in the aspects of soil improvement and environmental governance.

Description

technical field [0001] The invention belongs to the technical field of soil conditioners, and relates to a microcapsule soil conditioner and a preparation method thereof. Background technique [0002] At present, there are about 730 million hectares of arable land in the world, but the average annual land that cannot produce food due to degradation is as high as more than 5 million hectares. Due to the gradual occupation of a large amount of high-quality cultivated land in the development of urbanization, the situation of land resources in my country has become more and more urgent. Moreover, the quality of the land is also declining, which is mainly manifested as soil alkalization, soil compaction, soil pollution, loss of soil nutrient components, and microbial imbalance. Soil degradation not only reduces soil productivity, but also reduces crop quality, and even leads to the accumulation of toxic elements in crops. Therefore, maintaining soil quality, improving acid-alka...
