Abstract

The invention provides a biological liquid mulching film and a preparation method thereof. The biological nutritional liquid mulching film comprises the following components by mass: 0.5 to 1.5 parts of chitosan, 2 to 5 parts of peach gum, 1 to 2 parts of lactic acid, 0.5 to 1.5 parts of yeast extract and 100 parts of water. The preparation method comprises the following steps: mixing the lactic acid and 50 parts of water, adding the chitosan, stirring, heating, dissolving, and preserving heat to obtain a transparent solution; heating the residual 50 parts of water, dissolving the peach gum until the material is transparent and adding the yeast extract to obtain a mixed solution; and mixing the transparent solution and the mixed solution, stirring and cooling to obtain the biological nutritional liquid mulching film. The biological nutritional liquid mulching film has high biocompatibility and stress resistance to facilitate healthiness of crops, has high film-forming property to facilitate cold resistance, drought resistance and moisture preservation, is rich in various nutrients required by the crops to facilitate growth of the crops, is convenient to use, saves a large quantity of labor, can be degraded automatically and avoids white pollution.

Description

technical field [0001] The invention relates to a biological liquid mulch film and a preparation method thereof, belonging to the technical field of agricultural film. Background technique [0002] In order to resist drought, prevent cold, keep moisture, and ensure the healthy growth of crops, mulch, that is, plastic film, is widely used in rural areas to cover farmland. However, with the sharp increase in the amount of plastic film, the shortcomings or defects brought by it are becoming more and more prominent: first, in the operation process of plastic film, it takes a lot of labor, which is labor-consuming and time-consuming, and increases labor production costs; It is the waste plastic film after use, which dies because it cannot be degraded by itself, and the huge amount not only affects the normal agricultural production, but also causes great white pollution to the environment. Therefore, it is necessary to develop an agricultural mulch film that saves labor and does...
