Abstract

The invention relates to an anti-scorching diffuse-scattering greenhouse film special for fruits and vegetables and a preparing method thereof, and belongs to the technical field of film manufacturing. The anti-scorching diffuse-scattering greenhouse film special for fruits and vegetables is prepared from, by mass, 24%-25.5% of LLDPE, 35%-36.5% of LDPE, 14.5%-15.5% of MLLDPE2010MA, 14.5%-15.5% ofMLLDPE1018MA, 4%-6% of a long-lived master batch, 0.5%-0.68% of a PPA master batch and 3.5%-4.5% of an anti-scorching master batch. Through the greenhouse film prepared with the method, the directionof light rays is changed, strong light is changed into soft light rays, a spectrum transmitted on plants is changed, and is matched with the wave length absorbed by chlorophyll, plant growth is betterfacilitated, and the problem that crops are scorched is solved. The invention also provides the preparing method for the anti-scorching diffuse-scattering greenhouse film special for fruits and vegetables, and the preparing method is scientific, reasonable, simple and easy to achieve.

Description

technical field [0001] The invention relates to an anti-burn special greenhouse film for diffuse scattering fruits and vegetables and a preparation method thereof, belonging to the technical field of film manufacture. Background technique [0002] Most of my country's crop planting divisions are located in Shandong, Shanxi, Shaanxi, Henan and other regions. The crop planting can be divided into open-air planting and greenhouse planting. Due to different planting methods, the fruit harvest season is also different. Greenhouse planted crops are generally in the annual The harvest period is from the end of May to the beginning of June, while the harvest period of open-air crops is from the end of September to the end of October each year. Although the two planting methods have different harvest seasons, they will be burned by direct sunlight, also known as: sunburn, In particular, the crops grown in greenhouses are burned every year, accounting for 20%-30% of the total crop outpu...
