In order to produce higher quality fruit (ie middle and high grade fruit), fruit bagging has become a basic requirement in fruit cultivation. Here are a few simple ways to identify the quality of fruit bags. First, except for striped paper, most fruit bags are mostly yellow and black composite paper. Take a piece of paper or a fruit bag, and pour a small amount of white wine of 34-38 degrees on one side of the yellow (note that you cannot use high-alcohol liquor). Shake off the liquor in about one minute. Look at the reverse side. A small number of dots pass through or are not transparent. High-quality paper, if thoroughly penetrated in a short time, is poor quality paper. Second, the yellow side of the composite paper, rolled into a funnel, pour 60 ~ 80 °C hot water, wait a while to see the outside is not transparent, that is, high-quality paper. Third, in the yellow surface of the composite paper sprinkle a small amount of clean tap water or well water, the surface of the paper is hydrophobic, but there is water on the surface, the surface kind of greasy feeling, that is, high-quality paper. If water does not spill on the paper after it is sprinkled with water, it looks like the lotus leaf has a waxy texture and is a poor quality paper. Because the surface of the paper was coated with a hydrophobic agent, the hydrophobic agent was only applied to the surface of the paper. At that time, the water repellent was very good, but after being hung on the tree, it was exposed to the sun for a while, the hydrophobic agent was gone, and the fruit bag was permeable. Now.
