Problems solved by technology

[0003] However, there is no suitable standard for how to test the degradability of agricultural mulch paper for effective evaluation. The current degradability test method is mainly aimed at plastic-containing products, and cannot properly evaluate the degradable agricultural mulch paper qualitatively and quantitatively. For this reason, the present invention designs a test method for the degradation time of paper in soil, which simulates the degradation process of agricultural mulch paper in soil. The test process is simple and intuitive, easy to operate and controllable, and has strong pertinence. Degradation speed of agricultural mulch paper in soil

Abstract

The invention relates to a method for testing the degradation time of paper in soil, which divides the degradation time into preliminary degradation time and deep degradation time, and clarifies the test requirements, the test method and steps by adopting the method provided by the invention have the advantages of simplicity, intuition, easiness in operation, controllability and strong pertinence. The measured index can objectively reflect the degradation speed of the agricultural mulching film paper in the soil and has actual reference value and guiding significance, and the paper produced from the plant fiber raw material generally has the initial degradation time of 30-180 days and the deep degradation time of 100-400 days in the soil.

Description

technical field [0001] The invention relates to a method for testing the degradation time of paper in soil, and belongs to the technical field of agricultural mulch paper. Background technique [0002] The traditional agricultural mulch is a plastic film, which has the characteristics of airtight and moisture-proof. Its non-degradable nature has brought serious adverse effects on the ecological environment. The agricultural mulch paper produced from plant fibers is a good solution to the problem of agricultural mulch. For the problem of difficult degradation, using paper instead of plastic is biodegradable and has obvious advantages in ecological and environmental protection. It is also breathable and moisture-permeable, which is conducive to the growth of crops. It is an ecologically upgraded alternative to agricultural mulch. [0003] However, there is no suitable standard for how to test the degradability of agricultural mulch paper for effective evaluation. The current d...
