Hormone enhancement ①10-30 days before the normal harvest of apples, spray 750-1000 times the ethephon solution, and add 40-60×10 mg/kg sodium acetate to the ethephon solution to prevent fruit drop. After spraying, the full red or half red fruit is obviously increased, reaching 80% to 90%, and the sugar content is increased. ② Spraying 500～600×10 mg/kg rare earth solution twice during the fruit swelling period and fruit coloring period has a significant effect on apple coloring and yield increase, and can fully color most fruits. ③Spray 1000 times B solution once 45-60 days before picking the fruit, which is good for coloring.
It should be noted that the hormone enhancement method is adopted, and a small area test is performed first, and then a large area is promoted after success, so as to avoid phytotoxicity caused by improper use of hormones (affected by factors such as concentration and climate) .
In the middle and late stages of fruit growth, spraying 0.3% to 0.4% potassium dihydrogen phosphate solution once every 10 to 15 days for 2 to 3 consecutive sprays can significantly promote fruit coloring. In addition, spraying Yemianbao, Penshibao, Meiguolu, Huimanfeng (Gaomeishi) and other foliar fertilizers during the coloring period can not only increase the yield, but also significantly improve the color of the fruit.
Fruit bagging can make the fruit points smaller, clean the fruit surface, and increase the color index significantly. At the same time, it can also eliminate rust spots and reduce storage rotten fruits. Bagging—generally 40 to 50 days after blooming, flower and fruit thinning should be done before bagging, and insecticide and fungicides should be sprayed carefully once. In order to promote fruit coloring, bagged fruits should be removed in time. The bag is generally removed 15-20 days before the fruit is picked. If it is a single-layer paper bag, first tear open the bottom to make the bag an umbrella shape, wait 2 to 3 days for the fruit to adapt to the external environment before removing the bag; if it is a double-layer bag, remove the outer paper bag first, about 3 to 5 days later Then remove the inner anti-bacterial bag. Plastic film bags can be picked with bags.
Harvesting in the right time At present, most fruit farmers tend to advance the harvesting period, which affects the yield and is not conducive to coloring. Studies have shown that from mid-September to early October, the sugar content in the fruits of Red Fuji is still accumulating. The average daily weight gain of the fruits is about 1 gram. The increase of the anthocyanin content in the fruits begins to increase. The yield is increased by 5% to 10%, and it is beneficial to promote fruit coloring. The growth days from full bloom to fruit ripening are approximately: 120 days for the Tsugaru line, 155 days for the Marshal line, 160 days for the Golden Crown line, 165 days for the Jonagold line, 170 days for the Wanglin line, 175 to 180 days for the Fuji line, Qin Crown for 180 days.

Laparoscopic instruments are medical devices used in minimally invasive procedures. These instruments are designed to be inserted through small incisions in the body, allowing surgeons to operate with less pain, scarring, and recovery time than traditional open surgery.
Advantages of Laparoscopic Instruments:
1. Smaller incisions: Laparoscopic instruments allow the use of smaller incisions, reducing scarring, pain and recovery time.
2. Improved visualization: Laparoscopic instruments provide a better view of the surgical site, allowing for more precise and accurate surgical procedures.
3. Reduced risk of infection: Compared with traditional open surgery, laparoscopic surgery usually has a lower risk of infection.
4. Reduced blood loss: Laparoscopic instruments are designed to minimize tissue trauma, thereby reducing blood loss during surgery.
5. Faster recovery: Compared with traditional open surgery, laparoscopic surgery usually has a faster recovery time, allowing patients to return to normal activities sooner.
