Description
Technical field:
Wataru of the present invention and a kind of film containing polymer substance, relate to one further and turn ruddiness long-lived light conversion multifunctional ground-covering film.
Background technology:
Whole energy derive of crop vital movement and main resources are obtained by photosynthesis, and blade carries out photosynthetic organ, and the luminous energy that other pigment absorbs can only pass to chlorophyll just can cause chemical reaction later.Accounting for plant dry weight 90-95% organic substance is from photosynthesis, therefore, plant how is made to maximally utilise solar radiant energy to carry out photosynthesis, very large on the impact of farm crop, the light of different wave length is different to the growth effect of crop, the efficiency of light energy utilization of crop is very low, is about 1%, the visible importance improving the efficiency of light energy utilization and improve crop yield.
Mulch film is one of important substance data of agriculture production, and ground membrane technique greatly facilitates the raising of farm output and benefit in application agriculturally, has driven developing by leaps and bounds of the change of mode of agriculture and agricultural productive force.
But common ground film is passive utilize sun power, cannot realize Energy harvesting to greatest extent.
Sunlight is the complex light that different wave length becomes, and the energy of different wavelengths of light is different, plays a different role to farm crop, and simultaneously different farm crop are also different with reaction to the requirement of spectrum.According to farm crop Photosynthetic characteristics, utilize solar energy on one's own initiative, by improving the g and D environment of farm crop outside, affect the growth conditions of farm crop, strengthen effective light quality, improve the efficiency of light energy utilization of crop, crop biochemical effect is good, be chemical energy more light energy conversion, and be accumulated in organism, farm crop Jin mono-Walk is increased accumulation.Reach the object of increasing crop yield.
The royal purple light of wavelength 420-480nm can make Miao Jianzhuan, impels crop to produce more chlorophyll, improves the efficiency of light energy utilization, improves light Eat and the point of crop, reduces light compensation point, reduce and consume, increase accumulation.
Blade area and thickness are increased, and farm crop plants stems of looking healthy and strong is, with luxuriant foliage and spreading branches in leafy profusion, and fruit is very large, and the synthesis of the organic substance that is highly advantageous to and protein and non-carbohydrate are as the accumulation of starch.
The blood orange light of wavelength 620-680nm can improve the light Upon Cooperative Efficiency of farm crop, is conducive to the accumulation of carbohydrate.Infrared light has offsets the antagonistic action of ruddiness, weaken infrared light the anti-effect of tangerine, enhance the photosynthetic ability of chloroplast(id), be conducive to the increase of the biomass of crop, improve quality, increase yield.
The UV-light of 300-380nm not only to the growth of crop without benefit, also can make that Crop development is bad, physique is deteriorated, reduces anti-adversity ability, crop is easily caught an illness, blocks the growth of crop.The ultraviolet portion of longer wavelength has hormesis to farm crop, can promote the germination of seed and the maturation of fruit, and improve the content of protein and VITAMIN, particularly have the greatest impact in the fructescence, makes the fragrant and sweet and increase yield of fruit.
Blade is the base of crop photosynthesis synthesis of organic substance, nutriment needed for each organ-tissue of crop is mainly supplied by blade, crop can keep a unified entirety, the effective traffic structure all placed one's entire reliance upon in body, the photosynthate of crop has the feature of distributing nearby, the assimilate that the next blade part is made mainly is supplied to subcomponent and the root of plant, make seedlings root flourishing, and the assimilate that upper blade part is made is mainly for being transported to young leaves, spire and top, overground part is grown tall and big, healthy and strong.
Photosynthetic rate increases with the increase of illuminance, but when reaching certain numerical value, photosynthetic rate just reaches maximum value, and after this, even if illuminance continues to increase, photosynthetic rate is not also in increase, and this phenomenon is called light Eat and phenomenon.But because crop is population growth, blade is interlaced, often outer foil reached light Eat and, but inner and lower blade is still in below light Eat and point, even if crop at noon direct sunlight time do not reach Eat and the point of light yet, this improves the basis that intensity of illumination increases Efficiency of energy conversion photosynthesis potency just.
Summary of the invention:
The object of the present invention is to provide a kind of long-lived light transition function mulch film, this mulch film has light conversion properties and light selection function, add a kind of embedded photoluminescent material, can by photosynthesis of plant unwanted or need the UV-light of very few 290-380nm, and wavelength is at the yellow green light of 550-489nm, by the migration of light, conversion, and launch the ruddiness favourable to crop, blue light.Thus promoting and improve the photosynthetic efficiency of crop, plant absorbs the energy of the more effective sun by body chlorophyll and Hu Luo people's element, carries out photosynthesis, generate carbohydrate (comprising starch, Mierocrystalline cellulose) and discharge oxygen with carbonic acid gas and water.Complete the accumulation of biomass, in equal management with when not increasing input, reach the object improving quality and increase yield.
