Light blue film for grape cultivation

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 [0001] The invention relates to a covering film for a greenhouse, in particular to a light blue film for viticulture. Background technique [0002] Covering material is an important part of protected gardening, and its quality plays a vital role in the quality of crops. Plastic film has the advantages of light texture, low price, excellent performance, convenient use and transportation, etc., so it has become the covering material with the largest area in facility gardening. With the continuous improvement of high-quality, high-efficiency, and supporting facilities cultivation technology, the development and application of new covering materials have developed rapidly. A batch of multifunctional plastic films, mulch films, New covering materials such as sunshade nets and non-woven fabrics have been continuously introduced to the market, which has greatly improved the cultivation conditions in greenhouses and greenhouses. [0003] The greenhouse film in the ...
