Abstract

The invention belongs to the technical field of agricultural chemical fertilizers, and provides a soil-modifying root-promoting suspension fertilizer. The suspension fertilizer comprises the followingcomponents in parts by weight: 50-200 parts of a soil conditioner, 50-150 parts of a root promoting agent, 1-5 parts of a thickening agent, 220-800 parts of nitrogen-phosphorus-potassium fertilizers,10-200 parts of a medium trace element fertilizer, 0-100 parts of a pH regulator and 50-200 parts of water. According to the invention, physical resistance to growth of crop roots is reduced by improving the soil, and longitudinal growth of the crop root system is induced by the characteristic that a polyphosphate is not easily fixed by soil, so that spatial effectiveness of the fertilizer is improved. According to the invention, application convenience of the soil conditioner is improved, the soil improvement effect is optimized, and the problem that cultivation and conservation of cultivated land are disconnected is solved. The invention also provides a preparation method of the soil-modifying root-promoting suspension fertilizer, the preparation process is simple, equipment investmentis low, the prepared soil-modifying root-promoting suspension fertilizer is high in nutrient utilization efficiency, and obvious yield-increasing and quality-improving effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and particularly relates to a soil-improving and root-promoting suspended fertilizer and a preparation method thereof. Background technique [0002] Soil is a very important natural resource in agricultural production. Agricultural cultivation without protective measures can easily lead to a significant decline in soil quality and productivity, which in turn affects the output and quality of agricultural products, and even affects human health. The decline in soil quality has also become a constraint in my country. an important factor in agricultural development. Fertilizer is a very important means of production in agricultural production. In order to ensure sufficient output, a large number of chemical fertilizers are used in modern agriculture, which has adverse effects on the soil and the environment. Although my country vigorously promotes measures such as weight lo...
