Problems solved by technology

[0002] In the past 40 years, great changes have taken place in the development of the national apple industry, and the varieties have been continuously updated. New varieties such as 'Red Fuji' and 'Hanfu' have replaced old varieties such as 'Guoguang', 'Golden Delicious', and 'Red Marshal'. Progress, the proportion of high-quality fruit has been greatly increased, and has reached a certain height. However, as the proportion of modern people pursuing high-end products is increasing, market consumption is gradually in line with international standards, and the quality of products in the past is far from meeting people's living standards. In order to meet the ever-increasing needs, all walks of life put the promotion of high-quality development in the first place, and the apple industry is no exception. Water rust, bitter pox and other diseases and insect pests exist. The fruit surface is not smooth, and the color is not bright enough after picking the bag. Some fruits do not supplement calcium during the growing season. Bitter bean disease is very serious, which seriously affects the quality of apples. We have carried out in-depth research and experiments on this problem, and finally proposed a method to promote the cleansing and coloring of apple tree fruit
