Problems solved by technology

Some degradation is only molecular cracking in the superficial sense, and the added chemical components still exist in the soil and cannot be eradicated. After long-term cracking and accumulation, the invisible chemical substances can cause harm to soil, groundwater sources and crops and cannot be controlled.

Abstract

The invention relates to the field of an agricultural article, specifically to an agricultural mulching film degradable into a fertilizer. The agricultural mulching film comprises the following components, by weight part, 55-80 parts of plant ash, 45-55 parts of maize straw, 35-45 parts of wood fiber, 30-40 parts of soybean straw, 25-30 parts of hydroxyl cellulose, 15-20 parts of potassium dihydrogen phosphate, 5-10 parts of a water-retaining agent, 5-10 parts of a degradable adhesive and 15-20 parts of a plasticizer. The agricultural mulching film has an excellent thermal insulation and moisture retention effect, can provide crops with overall nutrients during usage, and can be self-degraded into a fertilizer in soil after trial, providing nutrients for next periodical cultivation.

Description

technical field [0001] The invention relates to the field of agricultural supplies, in particular to an agricultural mulching film that can be used as a chemical fertilizer. Background technique [0002] For decades, plastic mulch has been one of the main agricultural water conservation measures, which has driven the transformation of agricultural production methods and the rapid development of agricultural productivity. However, with the extension of the application life of the mulch film, its potential hazards in the past have gradually emerged. Due to its non-degradability, plastic mulch films lead to the deterioration of soil physical and chemical properties due to the remaining mulch film fragments in the field. At the same time, they pollute groundwater and the surrounding environment, which brings a series of social and environmental problems. The development of environmentally friendly mulch films and the development of plastic The substitute of plastic film has bec...
