Comparative test method for influence of organic fertilizers and inorganic fertilizers on activity of soil in paddy field

Abstract

The invention relates to a comparative test method for the influence of organic fertilizers and inorganic fertilizers on the activity of soil in a paddy field. The comparative test method comprises the following steps of: test design, fertilizer application, disease and insect prevention and control, soil physical and chemical property determination and soil acquisition. The comparative test method has the benefits that the physical and chemical properties of the soil, the number of microorganisms in soil fauna and the soil enzyme activity are tested, the contents of nitrogen, phosphorus and potassium, the number of soil bacteria, actinomycetes and funguses and the number of various main enzymes in the soil in the organic and inorganic fertilizer environment are comprehensively detected, a comprehensive and effective test method is provided for people to determine the optimum proportioning of the organic fertilizers and the inorganic fertilizers, the guide is detailed, and the method is scientific.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer cultivation, in particular to a method for comparative testing of the effects of organic fertilizers and inorganic fertilizers on rice field soil activity. Background technique [0002] In recent years, due to the extensive and perennial use of compound fertilizers, soil organic matter has been destroyed, and the decomposition of soil organic matter is achieved by the activities of microorganisms. After excessive nitrogen fertilizer is applied to the soil, the nitrogen supply of microorganisms increases by 1, and the corresponding consumption The amount of carbon in the soil increases by 25 parts, and the carbon consumed comes from soil organic matter. The low content of organic matter affects the activity of microorganisms, thereby affecting the formation of soil aggregate structure and causing soil compaction. [0003] In order to prevent soil compaction, people began to re-use organi...
