The fact that apples are getting smaller year by year may be the cause of these troubles

A small apple fruit directly affects the level of fruit prices. In recent years, the majority of fruit growers generally reflect that Apple fruit is getting smaller and smaller.

First, each year only knows the sparse branch but ignores the protection work of the wound: it causes the rot disease to occur year after year, which leads to the incomplete landscape and the deterioration of the tree vigor.

Second, pruning is irrational: fruit growers are generally satisfied that the fruit is shrinking, excessive dredging the fruiting branches of the year, leading to serious strips, unsteady tree vigor, stimulated the growth of nutrition, a large number of winter cut firewood every year, formed Vicious circle.

Third, only know the great transformation but neglected the strong pull sticks, clever fertilization: winter big cuts, regardless of the year.

IV. Excessive elimination of the middle and rear result branches on the trunk: Stimulation of the frontal growth advantage results in the outward shift of bald branches with no branches, and the canopy expanded year after year, resulting in the closure of orchards, poor ventilation, small fruit, and poor color. . Practice has proved that the high-quality fruit of the big fruit is generally in the middle and back part of the shoot.

V. Lazy to get in trouble Do not pay attention to strong pull branches: In order to cut the heavens and the earth in winter, make some good results sticks and new strong branches become firewood, severe plunder of the nutrient storage of fruit trees, weaken the tree (branch) Potential, the transpiration of the tree during the growth period, the leaves are small and the branches are weak.

6. Reluctant to eliminate front-end competition branches: resulting in infinite extension of the result branches and poor photosynthesis in the branches.

VII. No opinion, no tree in mind: This year's cutting method, next year's cutting method, there is no long-term plan, seriously undermined the growth of fruit trees, resulting in the size of the results.

VIII. Only the long-term knowledge of the results of the Zhizu Group does not know rejuvenation: year after year, the leading branch will grow weaker and weaker, the front end of the growth point is too much, nutrient consumption is large, and the result is small.

Nine, fertilization is not scientific: spring a shelling, diazo, phosphorus, light potassium and trace elements, a serious shortage of organic fertilizer, soil fertility decreased.

Ten, thinning of fruit and fruit is not standardized: There are generally heavy thinning and sparse flowering. During the flowering period, fruit trees are nutritious and their soil fertility does not help. Although spring fertilization, but because of low temperature, drought, rainfall, soil nutrients can not be absorbed by the tree in time, young fruit enlargement and flower bud differentiation to compete for nutrients, in order to reduce the tree's nutrient consumption during flowering, experts believe that sparse If it is worse than sparse flowering, it is not as good as sparse buds. Practice has shown that high-quality and large fruit are generally born on the middle and long, short branches of the middle and back parts of the resulting shoots.
