Embodiment 1

[0023] The pruning method of short dry small crown chestnut tree of the present invention is characterized in that, comprises the following steps:

[0024] S1 fixed stem: when the grafted seedling of field planting grows to greater than 60 centimeter height, carry out topping or cut fixed stem at 50 centimeters;

[0025] S2 Select and keep the first main branch: promote and cultivate strong new shoots under topping or cutting, first select a new shoot upright at the top as the central branch, and at the trunk below it at a height of 40 cm, the angle is open and strong A thick new shoot as the first main branch;

[0026] S3 select and keep other main branches: carry out heavy and short cuts on the central branches to promote new vigorous new shoots, according to the requirement of 23 cm intervals and interlacing each other, according to the standard for selecting the first main branch in step S2, select one at a time or multiple main branches, select and reserve the other two ...

Abstract

The invention discloses a method for pruning short-branch chestnut trees with small crowns, and relates to the technical field of shaping and pruning methods for economic forests. The method includesthe following steps that S1 branches are fixed, specifically, when planted seedlings grow to more than 60 cm, pinching or cutting of fixed branches are carried out at 50-60 centimeters; S2, first mainbranches are selected; S3, other main branches are selected; S4, side branches and branch groups are cultivated, specifically, while the main branches of all levels are selected and reserved, the first to third side branches are selected and reserved on the outside of the main branches following the requirements of alternately scattering, and repeat truncation or pulling of branches are carried out on the upright strong branches that affect the growth of the main branches and the side branches to cultivate into fruiting branch groups; and S5, spreading from core is formed, specifically, after3 or 4 main branches are selected, central branches are cut to keep each main branch growing evenly outwards in a core-spreading mode, and without the central main branches, a short-branch and smallcrown tree shape is formed. Beginning in a fourth year, the trees are retracted and renewed every year, and the crowns are controlled. The problems of excessive growth of chestnut, strong outside andweak inside, empty interior, external fruiting, low yield, poor quality, and low efficiency are effectively solved.

Description

technical field [0001] The invention relates to the technical field of pruning methods for economic forests, in particular to a method for pruning chestnut trees with short stems and small crowns. Background technique [0002] The average yield of chestnuts in Shandong is only about 140 kg per mu, which is low yield and low efficiency. The main reason is improper pruning techniques. In the past, the traditional habit was to let the chestnut tree be left alone. The chestnut tree is tall, with few fruits, and it is widely planted and poorly harvested. Later, after pruning was carried out, most of the tree shapes used were dry tree shapes. Although there were happy tree shapes, the trunks were too high, there were many main branches and side branches, and the number of mother branches was large. These tree shapes led to excessive growth of chestnuts. , Strong on the outside and weak on the inside, empty inside and outside, resulting in low yield, poor quality, low benefit, and...
