Description
Technical field:
Wataru of the present invention and a kind of film that contains polymer substance further relate to a kind of long-lived light conversion of blue light multifunctional ground-covering film that turns.
Background technology:
Whole energy derives and the main resources of crop vital movement are obtained by photosynthesis, and blade is to carry out photosynthetic organ, and the luminous energy that other pigment absorbs can only pass to chlorophyll just can cause chemical reaction later on.Accounting for plant dry weight 90-95% organic substance is from photosynthesis, therefore, how to make plant maximally utilise solar radiant energy to carry out photosynthesis, impact on farm crop is very large, the different wave length line is different to the growth effect of crop, the efficiency of light energy utilization of crop is very low, is about 1%, as seen improves the importance that the efficiency of light energy utilization improves crop yield.
Mulch film is one of important substance data of agriculture production, and the application of ground membrane technique on agricultural greatly promoted the raising of farm output and benefit, has driven the change of mode of agriculture and developing by leaps and bounds of agricultural productive force.
But common ground film is the passive sun power that utilizes, and can't realize to greatest extent the energy utilization.
Sunlight is the complex light that different wave length becomes, and the energy of different wavelengths of light is different, and farm crop are played a different role, and simultaneously different farm crop are also different to requirement and the reaction of spectrum.According to the farm crop Photosynthetic characteristics, utilize on one's own initiative solar energy, 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, the crop biochemical effect is good, be more light energy conversion chemical energy, and be accumulated in organism, farm crop Jin Yi Walk is increased accumulation.Reach the purpose of increasing crop yield.
The royal purple light of wavelength 420-480nm can make seedling healthy and strong, impels and makes the more chlorophyll of deposits yields, and blade area and thickness are increased, the farm crop plants stems of looking healthy and strong, with luxuriant foliage and spreading branches in leafy profusion, fruit is very large, the accumulation of synthetic and protein and non-carbohydrate such as the starch of the organic substance that is highly advantageous to.
The blood orange light of wavelength 620-680nm can improve the photosynthetic efficient of doing of farm crop, is conducive to the accumulation of carbohydrate.Infrared light has the antagonistic action of offsetting ruddiness, weakens the antagonistic action of infrared light, has strengthened the photosynthetic ability of chloroplast(id), is conducive to the increase of the biomass of crop, improves quality, increases output.
The UV-light of 300-380nm not only to the growth of crop without benefit, can make also that Crop development is bad, the physique variation, reduce anti-adversity ability, make crop easily catch an illness, block the growth of crop.The UV-light of longer wavelength part has hormesis to farm crop, can promote the germination of seed and the maturation of fruit, and improves the content of protein and VITAMIN, particularly has the greatest impact in the fructescence, makes fruit fragrant and sweet and increase output.
Blade is the base of crop photosynthesis synthesis of organic substance, the required nutriment of each organ-tissue of crop is mainly by the blade supply, crop can keep a unified integral body, the interior effective traffic structure of body all places one's entire reliance upon, the photosynthate of crop has the characteristics of distributing nearby, the assimilate that the next blade part is made mainly supplies 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, make the overground part growth tall and big, stalwartness.
Photosynthetic rate increases with the increase of illuminance, but when reaching certain numerical value, photosynthetic rate just reaches maximum value, and after this, even illuminance continues to increase, photosynthetic rate is not also increasing, and this phenomenon is called the light saturated phenomenon.But because crop is population growth, blade is interlaced, often to have reached light saturated for outer foil, but inner and lower blade still is in below light saturation point, even crop does not reach the saturation point of light at noon during direct sunlight 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 with 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 blue light favourable to crop.Thereby promote and improved the photosynthetic efficiency of crop, plant absorbs the more effectively energy of the sun by body chlorophyll and Hu Luo people's element, carries out photosynthesis with carbonic acid gas and water, generates carbohydrate (comprising starch, Mierocrystalline cellulose) and discharges oxygen.Complete the accumulation of biomass, in the situation that manage on an equal basis and do not increase input, reach the purpose that improves quality and increase output.
