Abstract

The invention discloses a greenhouse film for grape planting and a preparation method thereof, the greenhouse film comprises a plurality of stacked degradable material layers, and the degradable material layers are PLA resin layers and PBAT resin layers which are sequentially arranged at intervals; the color-matching film is characterized in that the PLA resin layer and the PBAT resin layer have different color-matching functions; a grid reinforcing layer is also arranged between the PLA resin layer and the PBAT resin layer. The organic photochromic particles and the inorganic photochromic particles are effectively combined, so that the greenhouse film presents different colors along with illumination, and the overall absorption effect on sunlight is good. The whole greenhouse film is made of environment-friendly materials, so that the greenhouse film is harmless to the environment and has extremely high popularization value.

Description

technical field [0001] The invention belongs to the field of grape planting, and in particular relates to a greenhouse film for grape planting and a preparation method thereof. Background technique [0002] Greenhouse viticulture is a form of viticulture in protected areas. It uses artificial protection facilities as a means to control natural conditions and artificially create ecological and environmental conditions suitable for grape growth and development. According to the characteristics of grape phenology, strengthen the technical Management, rationally determine the load, so as to improve product quality, and according to the desire of the producer, make the fruit ripen earlier or later, so that the time to market the fruit can avoid the peak season of the open-field grape market, and seize the highest economic benefits. [0003] The choice of greenhouse film is the key to the greenhouse planting technology, because the greenhouse film can directly affect the light and...
