Embodiment Construction

[0011] The present invention is based on the study of ginger's demand characteristics on temperature, light and humidity, aiming at the present situation that there is no special mulch film for ginger, and is developed through scientific and reasonable formula by adding suitable color masterbatch. The main technical indicators of the product are: the light transmittance is 40%-85%, the green light ratio of the transmission spectrum is increased by 5%-15% compared with ordinary mulch, and the film thickness is 0.006-0.02mm.

[0012] The processing and process requirements are described in detail below in conjunction with the accompanying drawings.

[0013] First, prepare no-drip insulation masterbatch (2), the weight percentage of each component is: LLDPE powder 90%-96% (1), non-drip LA-2 1%-5% (4), heat preservation agent talcum powder 3% -6% (5). The above raw materials are fully mixed and evenly heated, kneaded, extruded, drawn, cooled and cut into pellets, which becomes th...

Abstract

The invention relates to a special mulching film for ginger, which is composed of colorless agricultural polyethylene. The raw materials are calculated by weight percentage, green color masterbatch accounts for 1%-10%, non-drip heat preservation masterbatch accounts for 5%-20%, linear low density Polyethylene 75%-94% composition. The thickness of the special mulch film for ginger blown according to this formula is 0.006-0.02mm, the light transmittance is 40%-85%, and the ratio of green light in the transmission spectrum is increased by 5%-15% compared with ordinary mulch film. Using it for film-mulching cultivation of ginger can promote the growth of ginger, improve the yield and quality of ginger, and has a good prospect for popularization and application.

Description

[0001] 1. Technical field [0002] The invention relates to a special mulch film for ginger, which belongs to agricultural plastic film products. 2. Background technology [0003] Although the agricultural plastic mulch currently produced and applied has various specifications (width and thickness), there is no mulch film suitable for a certain crop according to the characteristics of the crop's demand for light, temperature, and humidity. my country is a big ginger producer, and it is urgent to develop a special plastic film suitable for ginger cultivation in view of the demand characteristics of ginger on temperature, light and humidity. 3. Contents of the invention [0004] The purpose of the present invention is to provide a special plastic mulch film for ginger cultivation, which can realize the coordinated regulation and control of temperature, light, humidity and other environments, which not only reduces the field operation steps, reduces labor intensity, but also ...
