Abstract

The present invention belongs to the field of one kind of weather resistant light-converting luminous farm film and its making process. The farm film contains base resin and following added components: at least one kind of visible light excited long afterglow light-converting agent, at least one kind of red light-converting agent, at least one kind of blue light-converting agent, and one compatible antiaging agent. The farm film has the light-converting and luminous characteristics, can luminesce at night stably for long time, so that plant can utilize sunlight effectively for increasing yield, fast maturing and reducing diseases and pests.

Description

technical field

[0001] The invention relates to the field of agricultural materials, in particular to an agricultural plastic film with light conversion and nighttime luminous properties and a manufacturing method thereof. Background technique

[0002] Agricultural plastic films are roughly divided into three categories according to their functions and development: (1) ordinary plastic agricultural films; (2) functional plastic agricultural films (including anti-aging, anti-fog, heat preservation, dust-proof, etc.); (3) control Functional plastic agricultural film (including spectral selection, spectral conversion, functional control, etc.). With the improvement of crop cultivation technology, ordinary agricultural plastic films are no longer suitable for the development of agricultural protective cultivation. In recent years, based on the principles of photoecology, the application of solar light energy conversion technology to agricultural films has been very active in th...
