First, resolutely overcome the concept of cherishing flowers and sparsely, and strictly follow the requirements of the indicators. Experienced persons can leave one fruit per 20-25 cm on average according to the distance method; those who are not skilled in grasping the amount of retained fruit can do it in accordance with the yield standard per unit area, and the normal fruit orchard contains 10000-12000 fruit pieces per acre. Decompose the tree branch by branch to obtain the concept of single branch of fruit. Second, adhere to quality first, the correct arrangement of fruit placement, ensure the healthy growth of fruit. The actual operation should be grasped: keep more peripheric fruits, and less stay pods; stay in the middle and long branches, leaving fewer short branches; leaving more fruit on both sides of the twigs, leaving less on the back and back; leaving the top florets, without chewing Flowers and buds; fruit with a secondary shoot of fruit trees, with or without the use of fruits without fruit buds; leaves fruit with more rosette leaves, less fruits with less rosette leaves; and as far as possible, central flowers, central fruits, no or less Use side lacing fruit; use large flowers, large young fruit, sparse small flowers, young fruit; use long-handled fruit, sparse short-handed fruit and fruit; use end-use fruit, sparse deformity, skewness, wounded fruit. Note that the problem is: 1. Prevent flowering frost. In order to prevent frost damage during the flowering period, the thinning and thinning of fruit can be divided into three steps: one is the sparse flowering sequence. After the inflorescences appear to be elongated, the inflorescences that are not properly planted should be removed in order according to the requirements of the fruit set indicator, and 10%-20% can be retained as a motorized fruit for insurance purposes. The second is fruit thinning. After flowering, if the fruit can be basically judged, the reorganization will be used as a single fruit, and the retained fruit will be reduced to about 5%. The third is the fruit setting. After the physiological fruit-fall period (mid-June-July-early), according to the growth and development status of young fruit, it is finally determined whether it is retained or not. This time, the fruits must be selected in strict accordance with the requirements of the indicators. It is better to leave less young fruits, and to remove the “bad†from those that cannot grow and develop into superior fruits. 3. According to the management level of the orchard and the tree age and branching tendency, the fruit set indicator shall be adjusted appropriately. High management level, small age, strong tree potential, should stay more, otherwise stay less. In particular, the old and weak trees should be based on the premise of increasing the growth of the tree, with as little fruit as possible, and even without fruit.

2. According to the market demand and the characteristics of varieties, flexible control of fruit retention indicators. Fruits and varieties that are popular with the market, such as Red Fuji, will not stay longer, generally leaving 10,000-11,000 young fruit per acre. The red stars may be enlarged appropriately, leaving 1,200-13,000 young fruit per acre; medium and small fruit, such as In general, the amount of fruits per mu is about 12,000.
Apple thinning and fruit thinning technology
Apple thinning and fruit thinning is an important part of achieving high quality and high yield. It is a production measure for artificially arranging fruit tree growth results. Its role is: to reconcile annual and small results; to increase the commodity rate of the fruit; to ensure the health of the tree. There are two principles that must be adhered to in the process of thinning and thinning fruit:
