Abstract
The invention discloses a light blue film for grape cultivation. The light blue film for grape cultivation is prepared from the following raw materials by weight percent: 65 to 75 percent of LLDPE (linear low-density polyethylene), 15 to 25 percent of LDPE (low-density polyethylene), and 6 to 12 percent of grape cultivation film functional master batch; the grape cultivation film functional master batch is prepared from raw materials with the following percentages by weight: 72 to 75 percent of an LLDPE powder carrier, 4 to 8 percent of a light stabilizer, 1.5 to 2.5 percent of an antioxidant, 12 to 17 percent of an antifogging agent, and 2 to 4 percent of a thermal-insulating agent; phthalo blue is added into the raw materials according to the principle that 10 grams of the phthalo blue are added into per ton of the raw materials; the thickness of the light blue greenhouse film is controlled between 0.03 millimeter to 0.04 millimeter. Compared with the prior art, the light blue film for grape cultivation provided by the invention has the following benefits: 1. the veraison is obviously 5 days earlier than that of grapes using other film treatment methods, so that fruits can obtain the natural color of the species earlier; 2. the light blue film material facilitates both glucose and fructose accumulations in the fruits.
Description
Technical field
The present invention relates to booth coverlay, particularly relate to a kind of vinegrowing lightweight blue film.
Background technology
Covering the important component part that material is facilities horticulture, its quality plays vital effect to the quality of crop.The advantages such as plastic sheeting has that quality is light, price is relatively low, function admirable, use and convenient transportation, thus become the covering material that in facilities horticulture, usable floor area is maximum.Along with high-quality, efficiently, auxiliary facility cultivation technique the most perfect, the development of novel covering material develops rapidly with application, a collection of have improve light transmission, improve heat insulating ability, extend using period, reduce the novel covering materials such as the multifunctional plastic thin film of cost, mulch film, sunshade net, adhesive-bonded fabric constantly to introduce to the market, significantly improve the cultivation condition in greenhouse, booth.
The awning film of prior art is all the effect that the most airtight space utilizing film to be constituted reaches to regulate temperature and humidity, thus plays the purpose promoting plant growing.But light itself can be caused certain obstruction by film itself so that the light wave of some specific wavelengths helpful to plant growing cannot act on plant, hampers the growth of plant to a certain extent.
Summary of the invention
The present invention is directed to deficiency of the prior art, it is provided that a kind of technique is simple, can be effectively improved the luminous environment under grape leaf curtain, improve period of maturation and the vinegrowing lightweight blueness awning film of quality of grape fruit.
For solving above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of vinegrowing lightweight blue film, is made up of the raw material of following weight percents: LLDPE65%-75%, LDPE 15%-25%, vinegrowing film functional master batch 6%-12%；Described vinegrowing film functional master batch is made up of the raw material of following weight percents: LLDPE powder carrier 72%-75%, light stabilizer 4%-8%, antioxidant 1.5%-2.5%, drip agent 12%-17%, heat preserving agent 2%-4%；Then adding phthalocyanine blue in described raw material, its addition is that raw material per ton adds 10 grams of phthalocyanine blues, and wherein, the THICKNESS CONTROL of described lightweight blueness awning film is at 0.03mm-0.04mm.
Further, as preferably, a kind of vinegrowing lightweight blue film, it is made up of the raw material of following weight percents: LLDPE70%, LDPE 20%, vinegrowing film functional master batch 10%；Described vinegrowing film functional master batch is made up of the raw material of following weight percents: LLDPE powder carrier 74.2%, light stabilizer 6%, antioxidant 1.8%, drip agent 15%, heat preserving agent 3%；Then adding phthalocyanine blue in described raw material, its addition is that raw material per ton adds 10 grams of phthalocyanine blues, and wherein, the thickness of described lightweight blueness awning film is 0.04mm.
As preferably, above-mentioned light stabilizer is the one in polymerized hindered amine light stabilizer, light stabilizer 944.
As preferably, above-mentioned antioxidant is the one in antioxidant B215, antioxidant 1010 and antioxidant 168.
As preferably, above-mentioned heat preserving agent is the one in silication soil, Kaolin, Pulvis Talci and infrared barrier.
Compared with prior art, the invention has the beneficial effects as follows: 1, blue film significantly improves fruit Anthocyanin content, what the colour-change period of the Fructus Vitis viniferae in blue film the most relatively other films processed shifts to an earlier date 5 days, promotes that fruit earlier reaches the color and luster that kind is intrinsic.2, lightweight blue film material all has facilitation to the accumulation of fruit glucose and fructose: when gathering, and the glucose of lightweight blue film canopy and fructose are the 121% and 125% of conventional canopy respectively.Its reason is: covering material is the key factor determining various covering material properties to different wave length spectrum through ratio, photosynthetic effective wavelength region is visible ray, the visible light transmissivity of non-transparent covering material is the highest more good, and nearultraviolet rays (wave-length coverage: 300 to 320nm) contributes to morphogenesis and the formation of anthocyanidin and can suppress plant excessive growth, and the transmitance that lightweight blue film is in wave-length coverage is 300 to 320nm interval is higher than film covering (seeing Fig. 1 and Fig. 2) of the prior art.
Accompanying drawing explanation
Fig. 1 is the transmitted spectrum of the lightweight blue film of embodiment 2.
Fig. 2 is the transmitted spectrum of the white films of comparative example.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail: 1 one kinds of vinegrowing lightweight blue film of embodiment, is made up of the raw material of following weight percents: LLDPE65%, LDPE 25%, vinegrowing film functional master batch 10%；Described vinegrowing film functional master batch is made up of the raw material of following weight percents: LLDPE powder carrier 72%, light stabilizer 8%, antioxidant 2%, drip agent 15%, heat preserving agent 3%；Then adding phthalocyanine blue in described raw material, its addition is that raw material per ton adds 10 grams of phthalocyanine blues, and wherein, the THICKNESS CONTROL of described lightweight blueness awning film is at 0.03mm.
