Abstract

The invention discloses an agricultural film with improved transmitted light quality. The agricultural film comprises a transparent plastic matrix, and the transparent plastic matrix contains 0.01-0.03 wt% of coronene and 0.01-0.03 wt% of an europium metal complex. A making method of the agricultural film comprises the following steps: uniformly mixing the europium metal complex, coronene and the transparent plastic, and melting and molding the obtained mixture to obtain the agricultural film. The maximum absorption wavelength of the coronene is 255 nm, the maximum emission wavelength of the coronene is 520 nm, the europium metal complex has strong absorption in a wavelength range of 260-420 nm, and the maximum emission wavelength of the europium metal complex is 613 nm. The fluorescence characteristics of the coronene and the europium metal complex are used to convert ultraviolet lights in sunshine into blue lights and red lights which facilitate the photosynthesis of crops, so the transmitted light quality of the agricultural film is improved, the production period of the crops is shortened, and the agricultural film has good economic benefits.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an agricultural film with improved transmitted light quality and a preparation method thereof. Background technique [0002] The use of agricultural greenhouse planting technology can provide counter-season vegetables for the dining table, which is the trend of agricultural development. However, the common agricultural film used in the existing agricultural greenhouses has no selectivity to light, and has limited improvement in promoting the photosynthesis of crops. [0003] Sunlight is a necessary condition for plant growth, but not all wavelengths of light in sunlight are beneficial to plant growth. The effect of light on plants is closely related to the quality of light, that is, the spectral composition. Every plant should have its own specific spectrum of optimal growth effects. Plants can grow rapidly, increase yield and improve quality under the optimal growth spec...
