Embodiment 1

[0019] The citrus adult trees are pruned as citrus adult trees, and the citrus adult trees are Wenzhou satsuma.

[0020] A kind of pruning method for controlling the summer shoots of Wenzhou Satsuma adult trees is as follows:

[0021] (1) When the summer shoots of Wenzhou satsuma adult trees grow 3 to 4 leaves between May and early July each year, that is, 3 to 4 cm, they are trimmed, and 2 to 3 leaves at the top of the summer shoot C are removed, and the summer shoot C 1 is retained. ~ 2 leaves, that is, the length of 1 ~ 2cm; after pruning, the remaining summer shoots are mature, and the other summer shoots on this branch are restrained;

[0022] (2) By the end of July and early August, when the autumn shoots of Wenzhou Satsuma adult trees begin to twitch, according to the length and / or thickness of the spring shoots in the Wenzhou Satsuma adult trees, cut off or keep the summer shoots retained in step (1) , to control the position of the autumn shoots:

Embodiment 2

[0027] The citrus adult tree is pruned as a tangerine adult tree, and the tangerine adult tree is a sugar orange.

[0028] A kind of pruning method of controlling the summer tops of Shatangju adult trees is as follows:

[0029] (1) When the summer shoots of Shatangju adult trees grow 3 to 4 leaves between May and early July each year, that is, 3 to 4 cm, they are trimmed, and the 2 to 3 leaves at the top of the summer shoot C are removed, and the summer shoot C is retained. 1 to 2 leaves, that is, the length of 1 to 2 cm; after pruning, the remaining summer shoots are mature, and the other summer shoots on this branch are restrained;

[0030] (2) until the end of July and early August when the autumn shoots of Shatangju adult trees begin to twitch, according to the length and / or thickness of the spring shoots in the Shatangju adult trees, cut off or keep the remaining in step (1) Summer shoots, control the location of autumn shoots:

Embodiment 3

[0035] The citrus adult tree is pruned as the pomelo adult tree, and the pomelo adult tree is Shatian pomelo.

[0036] A kind of pruning method of controlling summer tops of Shatian pomelo adult trees is as follows:

[0037] (1) When the summer tip of Shatian pomelo adult tree grows 3 to 4 leaves between May and early July each year, that is, 3 to 4 cm, it is trimmed, and the 2 to 3 leaves at the top of the summer tip C are removed, and the summer tip C 1 is retained. ~ 2 leaves, that is, the length of 1 ~ 2cm; after pruning, the remaining summer shoots are mature, and the other summer shoots on this branch are restrained;

[0038] (2) By the end of July and early August when the autumn shoots of Shatian pomelo adult trees begin to twitch, according to the length and / or thickness of the spring shoots in the Shatian pomelo adult trees, cut off or keep the summer shoots retained in step (1) , to control the position of the autumn shoots:

Abstract

The invention discloses a pruning method for controlling summer shoots of citrus adult trees. The method includes the following operating steps that, firstly, from May to early July of each year, summer shoots sprout on spring twigs of the citrus adult trees, when 3-4 leaves sprout on each summer shoot, 2-3 leaves at the top end of each summer shoot are removed, 1-2 leaves of each summer shoot are reserved, and the summer shoots are 1-2 cm long; after pruning, remaining summer shoot branches age, and sprouting of other summer twigs is inhibited; secondly, at the end of July and in early August, autumn twigs of the citrus adult trees start to sprout, the summer twigs reserved in the first step are cut off or reserved according to the length and / or thickness of the spring twigs in the citrus adult trees, and the sprouting positions of the autumn twigs are controlled. By means of the method, the summer shoots can be effectively controlled in time, manpower consumption is reduced, meanwhile, the summer shoot removing frequency is reduced, nutrients of citruses are kept, over-many scabs are avoided, damage to citruses is reduced, the fruiting rate is increased, and the yield is increased.

Description

technical field [0001] The invention relates to a pruning method for fruit trees, in particular to a pruning method for controlling summer shoots of adult citrus trees. Background technique [0002] Citrus, tangerine, pomelo, orange, etc. belong to the genus Citrus, often called citrus. It is a fruit tree that can shoot many times a year. The growth and development period of citrus fruit coincides with the period of summer shoots. If the amount of summer shoots of citrus is large, it will consume a lot of nutrients, which will cause conflicts between shoots and fruits, resulting in fruit fall and reduced yield. At the same time, summer is also the peak period for the occurrence of citrus diseases and insect pests. Excessive summer shoots may increase the probability of diseases and insect pests, such as whitefly, canker, leaf miner, etc. Studies have shown that the time of summer shoot release is closely related to the degree of damage caused by leaf miners. Therefore, att...
