Quick culturing method of early fruit high-yield walnut trees

Abstract

The invention discloses a quick culturing method of early fruit high-yield walnut trees. The method comprises: selecting good young trees to carry out fixed planting with a 4 - 6 m plant interval and 4 - 6 m row interval; in the second or third year after the young trees are planted, keeping three to four branches which are longer than 60 cm on the center trunk and culturing the three to four branches into first layer main branches; in the third or fourth year after the young trees are planted, selecting two to three branches above the first layer main branches and culturing the two to three branches into second layer main branches; in the fourth or fifth year after the young trees are planted, selecting two branches above the second layer main branches and culturing the two branches into third layer main branches; and at the same time, culturing two first level lateral branches on each first layer main branch, culturing two to three first level lateral branches on each second layer main branch, and culturing two first level lateral branches on each third layer main branch. Compared with conventional shaping trimming, the method shortens the tree culturing growth period by two to three years, so that high-yield tree structures can be cultured after planting for four to five years; and the yield is increased by 117%, and thus the method produces very good economical benefit.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to a rapid cultivation method for high-yielding early-fruiting walnut trees. Background technique [0002] Early fruit walnuts have the advantages of early fruiting, high yield, thin peel, high commercial value, small tree body, and easy picking. At present, early-fruiting walnuts are widely planted across the country, but for a long time, due to the lack of timely follow-up and implementation of the cultivation and management techniques of fruit farmers, the benefits of walnut garden construction have been greatly reduced, especially the lag in the cultivation of high-yield trees has seriously restricted In order to ensure the output of a single walnut plant and the overall ecological benefits of the walnut orchard, in the existing walnut cultivation, pruning is prone to the following disadvantages: First, after the tree grows to a certain shape and structur...

Problems solved by technology

At present, early-fruiting walnuts are widely planted across the country, but for a long time, due to the lack of timely follow-up and implementation of the cultivation and management techniques of fruit farmers, the benefits of walnut garden construction have been greatly reduced, especially the lag in the cultivation of high-yield trees has seriously restricted In order to ensure the output of a single walnut plant and the overall ecological benefits of the walnut orchard, in the existing walnut cultivation, pruning is prone to the following disadvantages: First, after the tree grows to a certain shape and structure, pruning is carried out again. Adjust and arrange the distribution of main branches in a timely manner, and remove dense branches, back branches, diseased and dead branches, overlapping branches, cross branches, parallel branches, etc. to solve the problem of ventilation and light transmission of the tree body, and it is difficult to achieve organic pruning and tree growth Combination, its degree of integration is not high, the second is that the traditional plastic pruning usually pays too much attention to the overall pruning of the tree shape, and ignores the cultivation of side branches, which affects its yield, and the third is that the time and method of traditional plastic pruning are not suitable for industrial development. Walnuts are needed. Conventional walnut pruning needs to be pruned after many years of growth. There are many branches, which not only increases the difficulty of the branch selection process and pruning operation, but also has a large amount of pruning, which is difficult for the masses to accept in actual production, and the overall pruning of the tree The nutrient consumption of the plant is large, which has a great influence on the growth of the root system, and the incision is large and the healing time of the incision is long.
