Problems solved by technology

The most commonly used method in the prior art is that PVC mulch does not have degradability, which is easy to cause environmental pollution; at the same time, the operation is not simple enough, the mulch with support ribs is not easy to lay and recycle, and the support ribs cannot be used multiple times
Ordinary PVC films in the prior art have poor air permeability and cannot be effectively degraded, which will affect the soil quality of the soil and limit the growth of plants in the later stage

Abstract

The invention discloses a combined degradable mulching film which comprises a double-layer biodegradable porous film layer. An interlayer of the double-layer biodegradable porous film layer is filledwith a nutrient layer, and a supporting framework layer is arranged below the double-layer biodegradable porous film layer. Each layer of the double-layer biodegradable porous film layer is 100-1000 pores per square meter in porous density. The supporting framework layer is a supporting frame in a shape of a Chinese character 'tian' and provided with splicing clamping grooves. The combined degradable mulching film has great heat preservation performance, breathability and degradability and has advantages of recyclability, low cost and convenience in use.

Description

technical field [0001] The invention relates to the field of film manufacturing, in particular to a combined degradable mulch film. Background technique [0002] The northern winter is dry and windy, and the relative humidity is low most of the time. It affects the development and growth of seeds, especially when the weather is dry and bad, and ultimately affects the survival rate of seedlings. Therefore, it is necessary to carry out cold and antifreeze treatment for seed cultivation. The most commonly used method in the prior art is that PVC mulch does not have degradability and is prone to environmental pollution; at the same time, the operation is not simple enough, the mulch with support ribs is not easy to lay and recycle, and the support ribs cannot be reused multiple times. The ordinary PVC film in the prior art has poor air permeability, and if it cannot be effectively degraded, it will affect the soil quality of the soil and limit the growth of plants in the later...
