Technical Field

The invention relates to the technical field related to agricultural planting, in particular to a degradable biological mulching solution and a preparation method thereof.

Background

The mulching film has the functions of water retention, fertilizer retention, moisture retention and the like, and has an important effect of improving the crop yield, so the mulching film is widely applied to agricultural planting.

The commonly used plastic mulching film is extremely difficult to degrade due to the high molecular structure, so that surface water is easy to permeate underground, and soil salinization can be caused after long-term use, and finally, the soil quality and the crop yield are reduced.

Therefore, the degradable biological mulching film becomes the main direction of the current research, and a plurality of related patent applications are provided at home, but many of the applications are limited to the water-resisting and moisture-preserving effects, so that the degradable biological mulching film is convenient to degrade, and has a single function.
