Description
Technical field
The invention belongs to agriculture field, and in particular to a kind of to have improvement through agricultural film of light quality and preparation method thereof.
Background technology
Vegetables in improper season can be provided for dining table using agricultural greenhouse planting technology, be the trend of agricultural development.It is but existing
Ordinary agricultural membrane used in agricultural greenhouse, without selectivity, improves limited to light to the photosynthesis for promoting crops.
Sunlight is the necessary condition of plant growth, but not the light of all wave bands is all beneficial to plant growth in sunlight,
The quality of effect and light of the light to plant is that spectral composition has very close relationship.Each plant should all have it specific most
Good growth spectrum.Plant can fast-growth, volume increase and raising quality under the conditions of optimum growh action spectrum.So change
Kind agricultural film has important meaning through light quality for improving sunlight utilization ratio, promotion plant growth.
CN106945363A discloses a kind of anti-aging conversion film, the anti-aging conversion light film include the first anti-aging layer,
The conversion coating that is arranged on the first anti-aging layer and coordinate the second anti-aging layer on conversion layer.The anti-aging conversion film uses
Sandwich format, so as to obstruct the decomposition of moisture content and oxygen to light conversion agent in air, is carried by increasing anti-aging layer on conversion layer
The stability of high conversion layer.The shortcomings that program is that the preparation process of film is numerous and diverse, and cost is high, and the adhesion between each layer compared with
Difference, easily peel off.

As a preferable technical scheme, the thickness of the agricultural film is 0.15~0.2mm.
It is above-mentioned that there is the preparation method for improving the agricultural film through light quality, comprise the following steps：
After europium metal complex, coronene and polyvinyl chloride are mixed, melt, shaping, obtain described agricultural film.
As a preferable technical scheme, the agricultural film is using extrusion the tape casting shaping.
It is above-mentioned that there is the application for improving the agricultural film for passing through light quality in agricultural greenhouse.
It is described that there is improvement can also contain lubricant, antioxygen through the agricultural film of light quality as a preferable technical scheme
The auxiliary agents such as agent, antifoggant, plasticizer, opening agent.
Beneficial effects of the present invention：
1st, the coronene selected by the present invention has excellent fluorescence, a length of 255nm of its maximum absorption wave, emission maximum ripple
A length of 520nm, europium metal complex have stronger absorption, maximum emission wavelength 613nm between 260~420nm.Using dizzy
The fluorescent characteristic of benzene and europium metal complex, the ultraviolet light in sunshine is converted into and is advantageous to the photosynthetic blue light of crops
And feux rouges, so as to improve the transmission light quality of agricultural film, promote the photosynthesis of crops, shorten the production cycle of crops, have
Good economic benefit.
2nd, coronene and europium metal complex are directly inserted agricultural film matrix by the present invention, can effectively overcome existing sandwich easy
The problem of peeling.
3rd, the present invention can improve the conversion of blue light and feux rouges simultaneously using coronene and europium metal complex as light conversion agent
Rate, overcomes that single transforming agent excitation spectrum is single, turns the problem of light efficiency is low.
