The invention discloses a special weeding film for fruit trees and a preparation process of the special weeding film. The special weeding film is prepared from the following components in percentage by mass: 65-80% of linear low-density polyethylene, 4-10% of low-density polyethylene, 6-10% of anti-aging masterbatch and 10-15% of light-blocking black masterbatch, wherein the anti-aging masterbatch is formed by reasonably matching, mixing and granulating according to demands. According to the preparation process disclosed by the invention, a conventional ground film blowing unit is adopted, PLC terminal software is adopted for inputting signals, particles which are well matched and mixed are put into a feed inlet of an extruder by a mechanical hand, and screw conveying, homogenization, compression, filtration, molding, traction, air ring cooling, coiling and packaging are performed; and the compression ratio of a mold head is controlled at 4.0-4.5 in molding, and the blow-up ratio of the film is controlled at 3.0-3.5. Compared with general molding requirements, the mechanical strength of the film is improved in comparison with that of the ordinary weeding ground film. According to the preparation process disclosed by the invention, the problems that a small amount of additives is added in the traditional process and the mixing with main raw materials is non-uniform to cause that the product quality is affected are solved, the stability of the product quality is ensured, the frequency of adding the materials is reduced, the time is saved and the product performances are further improved.

The invention discloses a method for preparing a culture medium with Chinese herbal medicine dregs. The method comprises the steps as follows: after the Chinese herbal medicine dregs are accumulated for anaerobic fermentation, compound bacteria of bacillus subtilis and aspergillus niger as per the bacterial content are added and mixed uniformly to enable the bacterial content concentration to be higher than 500 thousands bacteria per gram, then syrup is sprayed and mixed uniformly, after accumulation, the accumulated materials are covered with a black plastic film until the highest temperature in the accumulated materials reaches 55 DEG C, the black plastic film is removed for aerobic fermentation until the moisture content of the accumulated materials is lower than 45%, and the culture medium can be obtained through accumulation and ageing. The culture medium prepared with the method is low in salinity, low in EC value, large in cation exchange capacity and high in acid-base buffering capacity and saline-alkaline buffering capacity; meanwhile, by the aid of the culture medium, the soil looseness degree, the fertilizer keeping and water holding capacity and the heat insulation and ventilation capacity can also be improved; the culture medium is suitable for most of crops, even flowers, plants and the like with very strict cultivation requirements, the culture medium is suitable for mixing with any materials to be prepared into required media without limitations, and salinization conditions caused by excessive use can be avoided.
