Apple Tree Management Note Eight Promote Eight Controls
First, promote underground, control the tree
For apple whole trees, measures such as improving the soil and increasing soil fertility will increase the range of root distribution and promote robust root growth. At the same time, the growth of the tree was controlled and the ratio of root to crown was increased.
Second, to promote fruit, control long
The specific measures for the prosperous and prosperous growth of young trees are: (1) Pruning, such as ring cutting, girdling, pulling branches, dumping, etc. (2) Chemical control, such as soil application or leaf spray PP333. (3) Fertilizer control, such as phosphorus, potassium, nitrogen control and so on.
Third, promote short branch, control long branch
Fruit trees are transformed from the early fruit period to the full fruit period, which is the conversion process from long branches to short branches. By pulling branches to ease the trend, the formation of a large number of short branches is promoted; through the use of techniques such as topping and thinning (cutting large ears), a large number of long branches are controlled.
Fourth, promote spring shoots, control autumn shoots
Spring fast-growing period, big floods, fertilizers, foliar spray fertilizer to promote its growth; autumn fast-growing period, limiting the water and fertilizer, leaf spray 1000mg/LPP333, promote its development of branches full, improve wintering ability.
Fifth, promote the dry, control the main skills
The measures to promote the work of the Chinese government are to straighten the poles and straighten out the clubs, promptly removing the excessively low branches, round branches, twig neck branches, and competing branches. The measures to control the main branches are to control the branches and to ease the situation, and the ring peeling promotes fruit.
Six, promote both sides, control back
In the fruiting period, the main branch is raised to the shape of a "roof", and the branches on both sides are formed into a "beaded curtain" shape. In the weakened period tree, the main branch fell into a "ditch bottom", and the branches on both sides were raised like "eagle wings."
Seven, promote guilt, control the periphery
To cut the cut, to control the amount of shear outside the crown. Eliminate large branches at the outer ends of the backbone branches to ensure that the "external forces" are transparent. The guilt cultured a compact and robust result stick group.
Eight, promote fruit quality, fruit control
Through the cultivation of improved varieties, fruit bagging, the use of fruit-type agents, fruit transfer coloration, organic fertilizers and other measures to promote the fruit's internal appearance quality. To control the yield per unit area of ​​fruit, it is better to produce high-quality fruit and not to produce high-yield and low-grade fruit.
