Problems solved by technology

[0004] At present, many chestnut growers do not know how to prune or do not have a comprehensive grasp of pruning techniques. I don’t understand the principle, and I haven’t mastered the basic principles, resulting in closed orchards, overlapping and crossing main branches, too many large branches, insufficient fruiting branches in the inner chamber, moving fruiting parts outward, and declining fruit quality.
If there is too much branch thinning at one time, the cutting edge will easily lose water and shrink, which is not conducive to wound healing and prone to rot
After the chestnut tree is pruned, if you do not pay attention to maintenance, the chestnut tree is prone to various pests and diseases, which seriously affects the yield and quality of chestnut fruit.

Embodiment 1

[0028] The pruning method of Chinese chestnut fruiting tree is pruned after the annual Chinese chestnut tree leaves completely, and described method comprises the steps:

[0029] (1) Pruning of chestnut trees in the early fruiting stage: the chestnut tree grows to 4-7 years in the early fruiting stage, and the specific pruning method is as follows: the extended branch of the main branch is cut short to germinate branches, so that the crown of the tree is enlarged and adjacent The distance between the two tree crowns is 40-60cm; the vegetative branches growing in the middle and lower part, if there is room for growth, slow down or cut short, for the cultivation of future fruiting branches, and the vegetative branches without growth space should be cut off; chestnut trees in the early fruiting stage The pruning, per square meter of vertical projected area, leave 9-10 fruiting mother branches;

[0030] (2) pruning of chestnut tree in full fruit stage: described full fruit stage i...

Embodiment 2

[0044] The pruning method of chestnut fruit tree is basically the same as embodiment 1, the difference is:

[0045] The curing agent is made of the following raw materials in parts by weight: 30 parts of sweet potato stems and leaves, 10 parts of castor beans, 50 parts of oleander, 15 parts of tripterygium wilfordii, 10 parts of croton, 400 parts of clear water.

[0046] The preparation method of the curing agent is as follows: Add the stems and leaves of jicama, castor beans, oleander, tripterygium wilfordii, and croton into clear water and decoct. After decocting for 30 minutes, then ultrasonically vibrate for 10 minutes, the ultrasonic power is 400W, and the filtrate is obtained by filtration. Preservatives are available.

[0047] Described maintenance agent also comprises thiophanate-methyl and trichlorfon, directly adds thiophanate-methyl and trichlorfon in the filtrate and mixes evenly, and the volume ratio of thiophanate-methyl, trichlorfon, and filtrate is 1:1.2:2000....

Embodiment 3

[0050] The pruning method of chestnut fruit tree is basically the same as embodiment 1, the difference is:

[0051] The curing agent is made of the following raw materials in parts by weight: 40 parts of sweet potato stems and leaves, 15 parts of castor beans, 60 parts of oleander, 20 parts of tripterygium wilfordii, 12 parts of croton, and 650 parts of clear water.

[0052] The preparation method of the curing agent is as follows: add the stems and leaves of jicama, castor beans, oleander, tripterygium wilfordii, and croton into clear water and decoct, after decocting for 40 minutes, then ultrasonically vibrate for 20 minutes, the ultrasonic power is 750W, and the filtrate is filtered, that is Preservatives are available.

[0053] On the third day after spraying the curing agent, add lime water and spray until the chestnut tree is wet.

Abstract

The invention discloses a pruning method of castanea mollissima bearing trees and belongs to the technical field of pruning of castanea mollissima trees. According to the pruning method, pruning is conducted after leaves of the castanea mollissima trees completely fall each year. The pruning method comprises the following steps of pruning of the castanea mollissima trees in the early fruiting stage; pruning of the castanea mollissima trees in the full bearing stage, wherein pruning of strong bearing branch groups, treatment of reserved mother branches and thinning of nutrient branches are conducted. According to the growth characteristics of the castanea mollissima trees, the pruning method of the castanea mollissima bearing trees is provided. The pruning method is simple in technology andeasy to operate, reasonable distribution of the shapes and branches of the castanea mollissima trees can be guaranteed, thinning and reservation of the castanea mollissima trees are abstinent, the ventilation and air permeability are good, so that crowns are kept balanced, and leaf areas are increased; meanwhile, plant diseases and insect pests can be reduced, the tree potentials are restored tobe strong, the fruit yield is high, the quality is good, and the purposes of convenient management and increment of production and income are achieved.

Description

technical field [0001] The invention relates to a pruning method for chestnut trees, in particular to a pruning method for fruiting chestnut trees. Background technique [0002] Chestnut, also known as chestnut, chestnut, and wind chestnut, is a plant of the Fagaceae chestnut genus. It grows in areas with an altitude of 370-2800 meters, is more common in mountainous areas, and has been widely cultivated artificially. Chestnuts are rich in nutrients, and their vitamin C content is higher than that of tomatoes, and more than ten times that of apples. The minerals in chestnuts are also very comprehensive, including potassium, zinc, iron, etc. Although the content is not as high as that of hazelnuts, it is still much higher than ordinary fruits such as apples, especially the potassium content is 3 times higher than that of apples. Along with the raising of people's living standard, the nutritive value and economic value of Chinese chestnut are paid more and more attention to by...
