Organic fertilizer for loosening soil and retaining water and application of organic fertilizer

Abstract

The invention discloses organic fertilizer for loosening soil and retaining water. The organic fertilizer is prepared from the following components in parts by mass: 30 to 40 parts of peat soil, 10 to15 parts of sludge, 10 to 15 parts of weathered coal, 0.1 to 5 parts of lignin, 5 to 10 parts of clay, 0.5 to 1 part of borax, 1 to 3 parts of magnesium sulfate, 0.5 to 1 part of zinc sulfate, 0.5 to1 part of ferrous sulfate, 20 to 40 parts of limestone powder , 0.5 to 1 part of a soil water-holding agent, 0.05 to 0.1 part of a compound microbial agent, 0.05 to 0.1 part of yeast and 0.5 to 1 part of biological enzyme. According to the organic fertilizer for loosening the soil and retaining the water, disclosed by the invention, under the triple action of organic matters, a water-retaining agent and yeast enzyme, the fertilizer has the advantages that the granular structure of the soil can be effectively improved, moisture and temperature of the soil are kept, transformation of soil nutrients and absorption of plant nutrients are promoted and buffering performance of the soil is improved. In addition, the organic fertilizer disclosed by the invention has good retention property; the organic fertilizer has the effect of combining a macroscopic physical structure and a microscopic root system environment as well as quick and durable evident effects after being used.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a soil loosening and water-retaining organic fertilizer and its application. Background technique [0002] The normal growth and development of food and commercial crops depends on a good soil environment. The neutral soil environment is most conducive to the growth of most plants, and the overacid and overalkaline environment is not conducive to the normal growth of most plants. According to the national field positioning experiments and surveys conducted by the Soil and Fertilizer Research Institute of the Chinese Academy of Agricultural Sciences in recent years, in the cultivation of major agricultural areas in my country, the increase in grain production mainly depends on the application of large amounts of chemical fertilizers. The massive investment in planting and agrochemicals and the aging of ditch facilities have led to the general thinning of the cultivated ...

Problems solved by technology

However, when these fertilizer conditioners with a single character conditioning and improvement function are used, they act solely on a certain aspect of improvement, and it is difficult to produce a better improvement effect when the overall soil aggregate structure is out of balance, and its components are easily exposed to heat, salt, etc. , Oxygen (chemical oxidation) environment causes the inactivation of active functional components, which weakens the soil water retention effect and lasts for a short time, and if you continue to spray pesticides and fertilization in subsequent planting, the improvement effect will not last long
