Fruit and fruit
This method is used for dry-weekly management of normal, tree-intact, and non-senescent trees. According to the length of trunk in the middle of the trunk to determine the number of fruit remaining in the whole tree, the formula is: the number of fruit per plant should be kept: 0.2 dry perimeter dry perimeter. For example, if the circumference of the middle of the tree is 30 centimeters in length and it is substituted into the above formula, the number of fruits per plant is 0.23030=180 (fruit). In order to prevent accidental injury, an additional 10% insurance factor should be added. The actual number of fruits per plant is 180+18=198 (a fruit).
Distance operation is easy to master. Red Fuji apples leave 1 fruit per 25 centimeters or so, strong trees and weak branches 25 to 30 centimeters to leave 1 fruit, the fruit distribution is uniform. However, it is easy to keep more in practice. After using the dry cycle method to determine the total tree load, it would be more reasonable to use this method again.
Thinning and fruit thinning procedures
First sparse the tree, then sparse the tree; first sparse the tree, then sparse the tree; first sparsely flowering, the fruit quantity is especially multi-tree, then the sparse flowering, the fruit quantity is less; the first sparse stem branch, then the sparse auxiliary tree . In a tree, first sparse the upper part and then sparse the lower part; first sparse the inner gills, and then sparse the periphery; first, sparse flower buds and deformed flowers, and then sparsely buds. In the operation, follow the order of the branches, step by step, to prevent ignorance.
Thinning and thinning fruit should not be rigid
According to the tree vigor and branch vigor, many stay strong and fruitful; the weak leave little flowers and fruit; the ordinary trees retain more flowers and fruit on the middle and long fruit branches; the short branch trees leave more branch-length fruit on the branches, as far as possible. Do not leave flowers or fruit buds.
According to the appropriate load to stay in the flowers, leaving the fruit in bad weather conditions, sparse, sparse fruit should leave room, generally more than the appropriate amount of 15% to 20% of the insurance factor. To set the fruit when bagging, set the amount of fruit more than the appropriate amount of 5% to 10% more. At the same time, the fruit should be selected, the center fruit, the large fruit, the straight fruit, the drooping fruit, and the evenly distributed fruit, and the fruit, fruit, fruit, fruit, or fruit in the wrong direction must be removed to make the fruit on the tree moderate. And high quality.
In the principle of fruit retention on a single plant or on a single branch, in principle, there are fewer backbone branches and more subsidiary branches; more strong branches and less weak branches; less internal hemorrhoids and more peripheral leaves; and less or no left backbone branches; After leaving the branches on the former sparse, in order to facilitate later retraction. After adjusting the load of the whole tree, review it carefully to prevent it from being missed.
The selection of fruiting branches generally does not leave "horizontal fruit" ("counter fruit"), because the fruit is easily blown off by the wind, its coloration is limited to the end of the plant, and the fruit's back is easily cracked. In addition, the fruits growing on the fruit branches on the back of the backbone branches should be sparse because of their weak development, low light exposure and poor coloration. The flowers and fruit of the buds are often removed except for the preserved value of the tree or the frozen tree.
