Description
Technical Field
The invention relates to the technical field of agricultural vegetable greenhouse weeding films, in particular to a vegetable greenhouse double-ditch weeding film and a preparation method thereof.
Background
The fruit seedling breeding nursery has loose soil and rich fertilizer, is easy to breed weeds, takes labor and time for artificial weeding, has high cost, and can cause wasteland and affect the normal growth of seedlings in rainy weather. Chemical weeding does not find an ideal agent which does not generate phytotoxicity on fruit seedlings and can kill various weeds in a large area at present. For example, selective herbicides can only control part of gramineous weeds in a short period of time. In recent years, some special Gannan seedling raising households adopt plastic film mulching to prevent and kill weeds in the grafted seedling nursery lands of the citrus in the paddy field, and have the advantages of less labor consumption, low cost and obvious effect. Therefore, a quick-acting and permanent weeding technology is urgently needed.
The weeding mulching film is an agricultural mulching film with weeding function, which is prepared by adding black master batches or selective chemical herbicides into a common mulching film in the production process.
The weeding mulching film can be divided into the following two types. Namely a mulching film containing herbicide and a weeding mulching film containing sunlight shielding agent. The weeding mulching film containing herbicide is divided into two types, one type is a single-layer weeding mulching film containing double-sided medicine, and the mulching film is formed by premixing the herbicide, an auxiliary agent and resin or preparing master batches, and then performing blow molding on a common mulching film extruder. The mulching film has simple production process and less equipment investment, and the equipment for producing the common mulching film can be used for production. The mulching film is divided into two specifications of a common mulching film with the thickness of (0.14 +/-0.003) nm and a micro-film with the thickness of (0.006 +/-0.002) nm, and the weeding mulching film is mainly produced at home. A double-layer herbicide ground film containing single-side medicine is composed of the resin layer A containing herbicide and the resin protective layer B for preventing the herbicide from diffusing. The weeding mulching film has a drug on one side. The application is that the medicine surface is pasted on the ground, and the mulching film is more abroad. The thickness of each layer of the mulching film is 0.1mm, the total thickness of the double layers is 0.2 mm, the film thickness is convenient to recover, the pesticide effect can be fully exerted, but the cost is high, and the popularization is difficult at home. The herbicide mulching film is produced by coating herbicide on one side of common mulching film through coating and drying process, and has herbicide on one side and partial herbicide may be spread to the outer layer. The production is carried out in a small quantity in China, and the process is relatively complex. The weeding mulching film containing the sunlight shielding agent takes low-density polyethylene resin and linear low-density polyethylene resin as base materials, black master batch and auxiliary agent are added, and the weeding mulching film is formed by blow molding, the thickness of the weeding mulching film is controlled to be (0.008 +/-0.002) mm at home, and the weeding mulching film is produced in large quantities at foreign countries, but the mulching film influences the increase of the ground temperature.
The bean dregs are the by-products in the process of producing soymilk or bean curd, and the yield of the bean dregs is very large all the year around. China is the origin of bean curd production, has a long bean curd production history, and has large production and sales volume of bean curd and large corresponding bean dreg yield. The bean dregs are difficult to process because of poor taste, low utilization rate and low price.
