A bogey does not pay attention to cutting before the flowers. In the fruit area, there are many fruit growers who lack understanding of the importance and function of pre-harvest compounding, and their technology is also little known. Therefore, many fruit growers only attach importance to winter cutting and contempt for cutting before flowering, even if the complex shear is also a “fairyâ€. It should be noted that cutting before flowering is the continuation of winter shearing and is an important technique for further adjusting the relationship between vegetative growth and reproductive growth and determining the ratio of reasonable flower buds and leaf buds. Cutting before flowering can reduce the inefficient consumption of nutrients and water, and concentrate the nutrients and moisture to the remaining flower buds and leaf buds. In this way, it can not only overcome the phenomena of size, but also increase the fruit setting rate and commodity rate, increase economic efficiency, and can extend the economic life of the tree.
Second bogey does not understand the main object and the best period of complex shear. The main object of compound cutting is the apple tree that enters the result period. The best period is after the sprouting of spring trees to before flowering. At this time, the flower buds and large leaf buds of most varieties are already obvious and easily recognizable. The main differences in the external morphology of flower buds and leaf buds are:
The buds are round and narrow in neck, and most varieties come from three sides.
The color is shiny and luxuriant, and the scales clasp tightly together.
The buds are sharp and long, and the edges of the leaves are not thin and long.
The scales are loose and loose and the hairs are not bright.
Three bogey shears do not distinguish between the size of the year. The size of the apple tree is not the same as the cutting method. If it is a big year, it is necessary to exchange flowers for flowers, retain short fruit branches, light and short cuts, and long fruit branches; for moderate trees, mainly slow release, supplemented by light heads; for string flowers, usually 3-4 flower buds, Flower buds generally do not stay; thinning the weak branches in the pods, the saplings that are expanding the crown cannot leave the top flower buds. If it is a small year, flower buds should be left. Especially for large modified apple trees, more flower buds should be left. For the mean tree branches, they should be more short, so as to reduce the amount of flowering. For large stem buds that are sticky and sticky on the back of each main branch. Cut in order to cultivate fruiting branches; for large leaf shoot branches on both sides of the stem and drooping large leaf shoots with slow release, medium and long fruit shoots generally do not break, no flowers have been put for many years of uniaxial thin The long result branch should be retracted to avoid excessive annual spending. The size of the year trimmed mouth is:
The flowers of the New Year flowers are changed, and the long fruit branches are short.
Slowly put flowers in the branches, the results of the coming year depend on.
Small young flowers should stay more, and long fruit branches do not break.
In the middle branch, the middle branch will be cut, and the next year will surely come.
Four bogey shears do not distinguish the tree. The strength of the tree is not the same, the method of cutting is not the same, we must adhere to the principle of "strong trees to spend more time to cut and retain more flower buds, weak trees to cut back and leave less flower buds". For Wangshu cutting, slow-release and light-cut are the main factors. For the consecutive years of slow-release, a series of florets has been formed. In the complex shearing, the “strong branch and live hat, the golden branch and four caps, and the weak branch should take 2/3 of the flower buds†should be retracted. For the weaker growth and full of trees are flower buds, should be broken flower buds pruning, more sparse flowering branches, leaving more stout branches full buds, less sparse vegetative branches, less wounds.
Five bogey does not distinguish between varieties. Variety reaction is not the same, the method of cutting is not the same. For varieties that are not sensitive to pruning, such as the Qin Guan and the Golden Crown, for the auxiliary branches in the complex shearing, “the flowers should be bloomed and the flowers should be short and the long strings of flowers should be half.†For the pruning-responsive Marshal species and the long-twisted Fuji varieties that are sensitive to pruning, the results were predominantly slow, multi-branched, and multi-carve buds. See the flowers and then retract. In order to prevent red flowers in complex cutting, "shallow flower pruning" (that is, 1-2 leaf buds should be left before flower buds) and pruning by "shrinking and combining method" should be done (ie, 1-2 slowing should be left before flower buds are kept). Placement of nutrient twigs), and in the later stages of the results, attention should be paid to retracting the weakened uniaxial extension branch and to the cultivation of some small and medium-sized fruiting branches in order to preserve the vigor and prolong the life of the tree.
