At present, the agricultural film on the market comes from different manufacturers, and the thickness and price are quite different. When buying, the following three aspects should be noted: First, we must not only look at the product certification, but also pay attention to the quality of the appearance of the batch and the whole roll of agricultural film. The quality of the agricultural film is silver white and the whole roll is even and solid. Good agricultural film, horizontal and vertical pull is better; Second, we must measure the width of the film. Different crops, different coverage methods need different width of the plastic film, too wide and too narrow will not work. In addition, it is also necessary to compare the film thickness. The thickness of the mulching film has little to do with the increase in production, but it is closely related to the investment cost. The 0.005 mm high resistance film can cover 0.32 mu per kilogram, while the 0.012 mm ordinary film can only cover 0.6 mu, so it should be thin; Third, we must calculate the amount of money and do not buy blindly. The amount is based on the way they grow their own crops.
