Abstract
The utility model relates to agricultural mulching, specifically a kind of mulch film of prevention and control black shank, comprises film bulk, it is characterized in that: on film bulk, be coated with allicin layer, and the thickness of described allicin layer is 0.2 ~ 0.3 micron.The utility model in use, scribbles one of allicin layer facing to cigarette ridge ground mulching.Outstanding advantages of the present utility model is: utilize allicin to the remarkable suppression kill activity of black shank pathogen in the soil of cigarette ridge, to black shank, there is good control effect, there is water conservation heating effect simultaneously, be beneficial to cigarette strain and grow and the raising of tobacco production and value amount.
Description
Technical field
The utility model relates to a kind of vega mulch film, is specifically related to a kind of mulch film of prevention and control black shank.
Background technology
Black shank is a kind of destructive silborne fungal diseases, and the economic loss that China causes because of black shank is every year on average more than 100,000,000 yuan.Black shank pathogen survives about 3 years in soil, mainly movable in the scope apart from native table 0 ~ 5 cm, temperature 24.5 ~ 32.0 DEG C of infection processes the most applicable, and relative moisture keeps 3 ~ 5d more than 80%, and field there will be onset peak and popular.At present, plastic mulching because of its good water conservation, heat effect and be generalizable in tobacco cultivation, and consider for composite factors such as recruitment cost, water and fertilizer management, minimizing Pesticide-Polluted Soils, overwhelming majority cigarette district adopts common ground film coverage mode in the time of infertility, tobacco agriculture is produced and has played huge positive role, but common ground film covers the generation especially having increased the weight of black shank, popular and harm.
Retrieve Patents: the disease-resistant bicolor mulching film of a kind of weeding, insect prevention (number of applying for a patent CN201320421347.4.), its principal claim is: it comprises upper strata film body and bottom film body, adopts short-term adhesive layer composite integrated between the two; Described upper strata film body upper side is provided with silver gray coating; Described bottom film body look darkly, includes melanin.But this patent is mainly through better isolating heat insulation effect, promotes photosynthesis of plant and growing, thus improving disease resistance of plant.
Utility model content
A kind of simple structure, design science, prevention and control black shank mulch film easy to use that the purpose of this utility model provides specially based on above-mentioned prior art situation just.
The purpose of this utility model is achieved through the following technical solutions: a kind of mulch film of prevention and control black shank, comprises film bulk, it is characterized in that: on film bulk, be coated with allicin layer.The thickness of described allicin layer is 0.2 ~ 0.3 micron.
When the utility model uses, will one of allicin layer be scribbled facing to cigarette ridge ground mulching.
Beneficial effect is: the utility model utilizes allicin to the remarkable suppression kill activity of black shank pathogen in the soil of cigarette ridge, to black shank, there is good control effect, there is water conservation heating effect simultaneously, be beneficial to cigarette strain and grow and the raising of tobacco production and value amount.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. film bulk 2. allicin layer.
Embodiment
The utility model is described further below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of mulch film of prevention and control black shank, comprises film bulk 1, wherein: on film bulk 1, be coated with allicin layer 2, the thickness of allicin layer is 0.2 ~ 0.3 micron.
When using the utility model, will one of allicin layer be scribbled facing to cigarette ridge ground mulching.Adopt when tobacco cultivation mulch film of the present utility model to cover, obviously can reduce black shank and occur, there is water conservation heating effect simultaneously, be beneficial to cigarette strain and grow and the raising of tobacco production and value amount.
