Problems solved by technology

[0003] At present, the longan trees that have entered the mature stage, especially longan trees that have grown for more than 10 years, generally have the problems of too many large branches, tall crowns, bare inner chambers, flat tops, low yields, and difficulty in picking fruits. Difficulty, many fruit growers are at a loss for such trees, or abandon them for management, or plan trees, causing great losses
[0004] At present, people's pruning method for old longan trees is to short-cut longan trees every year, which will increase the workload of fruit farmers, and the yield of longan is high

Embodiment 1

[0018] The test site is a longan garden in Donghuang, Daxin County, Chongzuo City, Guangxi. Tree selection is to select 50 longan trees more than 10 years, and the pruning and pruning all cuts the crown of longan tree flat, as figure 1 As shown, all the upper part of the old longan tree is cut off, leaving the trunk and branches, and the pruning is carried out before the spring equinox; the pruning is carried out at a temperature of 20°C; the pruning crown is cut off the ground 1.5m, and the trunk Trim to 1.2m from the ground, so that the interface of the longan tree has a concave cross section. In the control orchard, 50 longan trees more than 10 years old were pruned and pruned according to the conventional method of pruning year by year.

[0019] Test results: According to the data statistics in the third year after pruning and pruning, the average yield of each longan tree in the 50 pruned longan trees in Huang’s longan garden and the average yield of each longan tree in ...

Embodiment 2

[0022] The test site is a longan garden in Dongzhou, Daxin County, Chongzuo City, Guangxi. Tree selection is to select 50 longan trees more than 10 years old, and the pruning and pruning will all cut off the longan tree crown; as figure 1 As shown, the upper part of the old longan tree is completely cut off, leaving the trunk and branches, and the pruning is carried out before the spring equinox; the pruning is carried out at a temperature of 20°C; figure 2 As shown, the crown of the pruning pruning tree is truncated to 1.5m above the ground, and the trunk is trimmed to 1.2m above the ground, so that the interface of the longan tree is in a concave cross section. In the control orchard, 50 longan trees more than 10 years old were pruned and pruned according to the conventional method of pruning year by year.

[0023] Test results: According to the data statistics in the 6th, 7th, and 8th years after pruning and pruning, the average yield of each longan tree in the 50 pruned ...

Embodiment 3

[0027] The test site is a longan garden in Dongzhang, Daxin County, Chongzuo City, Guangxi. Figure 4 shown. Tree selection is to select 50 longan trees more than 10 years old, and the pruning and pruning will cut off all the crowns of longan trees; the pruning and pruning will be carried out before the vernal equinox; image 3 As shown, the crown of the pruning pruning tree is truncated to 1.5m above the ground, and the trunk is trimmed to 1.2m above the ground, so that the interface of the longan tree is in a concave cross section. The middle part of the longan tree has an obvious downward concave surface shortly after it grows. The control orchard is pruning and pruning 50 longan trees more than 10 years old according to the conventional method of shortening year by year.

[0028] Test results: According to statistics on the cost of pruning and pruning, the total cost of pruning and pruning each old longan tree in Zhang’s longan garden is: 50 yuan, and the total cost of pr...

Abstract

The invention discloses a longan tree retraction modifying method, and belongs to the technical field of fruit growing. The longan tree retraction modifying method comprises the steps of selecting trees, and trimming and pruning branches. During trimming and pruning of the branches, all crowns of longan trees are truncated, and the branches are trimmed and pruned at one step, so that the labor amount is reduced, and the cost is lowered; meanwhile, high yield and stable yield in successive years for aged longan trees are realized.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a longan tree retraction transformation method. Background technique [0002] Longan is one of the tropical fruit varieties in my country. Its pulp has anti-oxidation, anti-anxiety, anti-cancer, lipid-lowering, heart-protecting and antibacterial effects, and longan meat can be processed into convenient longan ointment, delicious juice and certain The health wine with high efficacy has gradually become the development from single fruit consumption to the deep processing of health food. The market development prospect is very broad. Longan is not only a delicious fruit, but also has the functions of strengthening yang and nourishing qi, nourishing the heart and spleen, and nourishing the body after eating. Blood soothes the nerves, moisturizes and beautifies the skin, and can treat anemia, heart palpitations, insomnia, forgetfulness, neurasthenia, post-illn...
