Problems solved by technology

[0003] At present, there are many types of agricultural plastic greenhouse films that are widely used in production. Although there are many types of product specifications (width and thickness), there is no greenhouse plastic film that is produced according to the light-demanding characteristics of crops and is suitable for a certain crop.

Embodiment Construction

[0011] The present invention is based on studying the light-requiring properties of ginger, aiming at the present situation that there is no special greenhouse film for ginger, and is developed through scientific and rational formula by adding suitable color masterbatch. The main technical indicators of the product are: the light transmittance is 60%-85%, the ratio of green light in the transmission spectrum is 5%-15% higher than that of ordinary greenhouse films, and the film thickness is 0.02-0.15mm.

[0012] The specific processing procedures and requirements of this product are as follows: First, prepare the non-drip anti-aging masterbatch (2), the weight percentage of each component is: LLDPE powder 62.5%-82.5% (commercially available) (3), no drop agent LA- 2 10%-20% (5), insulation agent talc 5%-10% (6), antioxidant B215 0.5%-1.5% (7), light stabilizer 944 1%-3% (8) and light stabilizer 622 1%-3% (9). The above raw materials are fully mixed and uniformly heated, kneade...

Abstract

The invention relates to a shed film special for ginger. The shed film consists of two to three kinds of colorless agricultural polyethylene (containing ethylene vinyl acetate EVA resin), and is prepared from the following raw materials in percentage by weight: 0.5 to 10 percent of green color masterbatch, 5 to 20 percent of dropless anti-ageing masterbatch, 35 to 80 percent of linear low density polyethylene (LLDPE) and 10 to 35 percent of LEPE or EVA. The shed film special for the ginger, which is prepared by blow molding, has the thickness of 0.02 to 0.15mm, the light transmittance of 60 to 85 percent and the spectral green light transmittance rate improved by 5 to 15 percent compared with that of the common shed film. When the shed film covers a shed for culturing the ginger, the illumination environment in the shed can be improved, the ginger is promoted to grow, and the ginger yield and quality are improved.

Description

[0001] 1. Technical field [0002] The invention relates to a special greenhouse film for ginger, which belongs to the special plastic greenhouse film product for crops. 2. Background technology [0003] At present, there are many types of agricultural plastic greenhouse films that are widely used in production. Although there are many types of product specifications (width and thickness), there is no greenhouse plastic film that is produced according to the light-demanding characteristics of crops and is suitable for a certain crop. Ginger is an important agricultural economic crop in my country. Light intensity and light quality have a significant impact on its growth and functional components. In order to improve the yield and quality of ginger, it is urgent to develop a special plant suitable for the protection and cultivation of ginger according to its light demand characteristics. Greenhouse film. 3. Contents of the invention [0004] In order to solve the problem of...
