Although there was a “divergence†in prices for this year's Apples, the difference between bagging and non-bagging, background green color and background color, and poor light quality and surface light still doubled. In a recent interview with Heyang, the reporter found that some fruit growers followed the “Huang Li†card time in previous years and grabbed the bag early to “pursue high pricesâ€. As a result, Qingtou’s coloration was slow and the background color was poor. Price discount, bagged fruit sold a Cape fruit price. The fruit surface is hard to color The time of bagging is too early to take off the bag prematurely, the fruit maturity is poor, the content of reducing sugar and soluble sugar is low, and the accumulation of anthocyanin is increased slowly. When the accumulation of chlorophyll increases rapidly, the phenomenon of greening appears. According to experienced fruit farmers, when there is a phenomenon known as "green head", the time for bag removal is delayed by three or five days. The effect before and after the time is "double heaven". Unfavorable climate influences Before the bag is taken out, it is necessary to look at the short-to-medium-term weather forecast. If the weather with the temperature higher than 30°C after bagging lasts for 5-7 days, it is not conducive to fruit coloring. Out of bag time should be flexible From the point of view of the United States and the United States and the United States and the United States and the United States, the beginning of the bag-breaking period should not be a “card time,†but should be based on the de-greening status of their orchards, the strength of the tree, and the pre- and post-bagging conditions. The climate conditions are determined flexibly. With good bleaching, moderate tree vigor and weak rainfall before and after bag removal, bags should be taken out as early as possible; “Chaotou†should be large and tree vigor should be prosperous. It should be delayed for 3 to 5 days. The general principle is: picking off the good and then picking the bag, fade the green worse late a few days; the tree is weak and early, the tree vigorously late; when the rain is not equal, it is not the same time.

Regardless of the strength of the tree, it is relatively early and good that the weak trees are green, and the dark trees are relatively late and poor. The reason is that the chlorophyll content of the bagged fruit is gradually reduced under shading conditions, but as long as the tree grows normally after the bag is removed, the chlorophyll of the leaves and fruits of Wangshu is constantly being exchanged. The more prosperous the tree vigor, the quicker the fruit exchanges after seeing light. The tree vigor is relatively weak, and the amount of chlorophyll exchanged after fruit removal is small.
