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, relate in particular to a kind of viticulture lightweight blue film.
Background technology
Cladding material is the important component part of facilities horticulture, and its quality plays vital effect to the quality of crop.The advantages such as plastic film has that quality is light, price is lower, function admirable, use and convenient transportation, thereby become the cladding material of usable floor area maximum in facilities horticulture.Constantly perfect along with high-quality, efficient, auxiliary facility culture technique, development and the application of novel cladding material develop rapidly, a collection of have a light transmission of improvement, improve heat insulating ability, extend using period, reduce the novel cladding material such as multifunctional plastic film, mulch film, sunshade net, adhesive-bonded fabric of cost and constantly introduce to the market, greatly improved the cultivation condition in greenhouse, booth.
The horticultural covering film of prior art is all to utilize the relatively airtight space that film forms to reach the effect that regulates temperature and humidity, thereby plays the object of Promoting plant growth.But film itself can cause certain obstruction to light itself, and some cannot be acted on plant the light wave of the helpful specific wavelength of plant growth, has hindered to a certain extent the growth of plant.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of technique simple, can effectively improve the luminous environment under grape leaf curtain, improve the blue horticultural covering film of the maturing stage of grape fruit and the viticulture of quality lightweight.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of viticulture lightweight blue film, raw material by following percentage by weight is made: LLDPE65%-75%, LDPE 15%-25%, film functional master batch 6%-12% for viticulture; Described viticulture is made up of the raw material of following percentage by weight with film functional master batch: LLDPE powder carrier 72%-75%, light stabilizer 4%-8%, antioxidant 1.5%-2.5%, drip agent 12%-17%, heat preserving agent 2%-4%; Then in described raw material, add phthalocyanine blue, its addition is that raw material per ton adds 10 grams of phthalocyanine blues, and wherein, the THICKNESS CONTROL of the blue horticultural covering film of described lightweight is at 0.03mm-0.04mm.
Further, as preferably, a kind of viticulture lightweight blue film, is made up of the raw material of following percentage by weight: LLDPE70%, LDPE 20%, film functional master batch 10% for viticulture; Described viticulture is made up of the raw material of following percentage by weight with film functional master batch: LLDPE powder carrier 74.2%, light stabilizer 6%, antioxidant 1.8%, drip agent 15%, heat preserving agent 3%; Then in described raw material, add phthalocyanine blue, its addition is that raw material per ton adds 10 grams of phthalocyanine blues, and wherein, the thickness of the blue horticultural covering film of described lightweight 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, talcum powder and infrared barrier.
Compared with prior art, the invention has the beneficial effects as follows: 1, blue film significantly improves fruit Anthocyanin content, the colour-change period of the grape in blue film obviously, compared with 5 days in advance of other film processing, promotes that fruit earlier reaches the intrinsic color and luster of kind.2, lightweight blue film material all has facilitation to the accumulation of fruit glucose and fructose: while gathering, the glucose of lightweight blue film canopy and fructose are respectively 121% and 125% of conventional canopies.Its reason is: cladding material is the key factor that determines various cladding material performances to the ratio that sees through of different wave length spectrum, photosynthetic EWL region is visible ray, the visible light transmissivity of transparent cladding material is more high better, and near ultraviolet ray (wave-length coverage: 300 to 320nm) contributes to the formation of morphogenesis and anthocyan and can suppress plant excessive growth, and the transmitance of lightweight blue film in wave-length coverage is 300 to 320nm intervals is higher than film covering of the prior art (referring to Fig. 1 and Fig. 2).
Brief description of the drawings
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.
