First, the head is too heavy. Because the upper part of the main branch of the tree is rotten, there is no way, only three or four main branches are left at a time. The fruit trees are too high. In order to facilitate bagging, flower thinning and fruit thinning, the head is put in place at one time, resulting in an imbalance between the underground and the ground. Trees show a lot of peeling, and when they stop growing, they can't stop growing normally.

Second, the head drops too fast. For arbor, the tree can't start to lose its head until it is 12 or 13 years old. Because trees over 12 years old have entered the reproductive growth period, they will not turn around a lot at this time, but they cannot turn around too quickly and cannot be put in place at one time.

Third, off-year trees fall. Fruit presses the tree, and the tree obeys. Fruit trees are reluctant to drop their heads during the Chinese New Year, and then drop them after the results. When there are few fruits on the trees in the new year, they will be unwilling to bow their heads, resulting in long trees.

Fourth, winter pruning is unreasonable. Plastic pruning in winter is two concepts, which are used by some fruit farmers at the same time, resulting in excessive overlapping force after pruning, resulting in trees full of trees. Teacher He Jucai often says that the teacher is on the tree when pruning in winter, so pruning is the best teacher, so we must sum up our experience and prune reasonably.

5. Irrational fertilization. Zhongnongle has repeatedly publicized the benefits and functions of applying base fertilizer in autumn, but some fruit farmers didn't apply fertilizer until the next spring, and it was mainly nitrogen fertilizer or fertilizer with high nitrogen content, so the fruit trees didn't stop growing until they stopped growing.

6. Zhongnongle has been advocating water-soluble fertilizers for topdressing in summer for many years. Because of its high content, strong fertility and short fertilizer efficiency, water-soluble fertilizer is a good fertilizer for topdressing in summer. However, when some fruit farmers topdressing at the end of July and the beginning of August, it takes about 20 days to transform compound fertilizer, and its fertilizer efficiency can reach about two months. Therefore, topdressing with compound fertilizer can't stop the growth of autumn shoots on time.

Seven, watering too many times. Some fruit farmers water it six or seven times a year, and the more they water it, the longer it will be. Zhongnongle Demonstration Park is generally watered only two or three times a year, and the fruit is very big. Xue Ruzhu's orchard in Beili Village, Beijing Township, Linyi County was watered only once this year, and now the fruits on the trees are round. So the fruit tree must let it eat and drink well, and dare not eat and drink well.
