Abstract

The invention discloses a water-retaining paper mulch film. The preparation raw materials of the water-retaining paper mulch film include: 75-90 parts by weight of crop straw, 5-15 parts by weight of a far infrared heat catalyst, and 3-15 parts by weight of a water-retaining agent. The water-retaining paper mulch film also includes degrading bacteria. The water-retaining paper mulch film contains the water-retaining agent, can better absorb water and retain water, provides adequate moisture to crop, and guarantees the water demand of crop during growth. According to the invention, crop straw is employed as the basic raw material to prepare the water-retaining paper mulch film, which is rich in plant fiber and can be used as a crop growth fertilizer after degradation.

Description

technical field [0001] The invention relates to agricultural mulch, in particular to a water-retaining paper mulch. Background technique [0002] Mulch film is the ground covering film, covering the ground, which can increase soil temperature, maintain soil moisture, improve fertilizer efficiency, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc., and promote plant growth. It has been more than 30 years since the small-area test of mulch film was carried out in 1979. At present, mulch film has been popularized and applied in 31 provinces, municipalities and autonomous regions across the country. It is used on more than 40 crops such as grain, cotton, oil, vegetables, melons and fruits, tobacco, sugar, medicine, hemp, tea, and forests. It is well received by farmers. Welcome. [0003] However, ordinary agricultural mulch film is PE film, which is difficult to degrade, and it takes hundreds of years to completely d...
