Pomegranate tree results overall branch update technology

Pomegranate tree result The overall update of the branch group is the updating technology based on the result branch group, instead of the result branch unit update. Now we summarize the technical description as follows:

First, the result tree branch updated tree structure

In terms of plasticity, the tree shape still adopts single-spheronization spherical shape, two dry and three dry fun shape, multi-dry cluster semi-circular high-yield tree shape, does not change the spatial structure, in the fertile garden can be appropriately enlarged main branch or large result branch The relative distance between groups. When the spacing between the branches is not enough, the competition between light and light will occur, and the branches and branches in the strong and dry branches will be separated. In this case, the branches should be promptly retracted or removed to ensure that the branches are properly maintained. Spacing, practically thin and dense, thin and dense, and dense branches. In the crown, it should be relatively reduced, leaving enough space for the growth of new branches, not to make the tree artificially induced by changing the trimming methods, resulting in the resulting adverse effects.

Second, the results of the entire branch of the training technology

When the current branch of the production park is completely updated, the following methods should be used to cultivate the water on the basis of rational fertilization and irrigation and strong trees.

Pruning during dormancy should severely retract the large and medium-sized branch, or even retract the extension branches of all the branches of the stem, leaving only the middle and small branches of the tree and the vigorously growing one-year-old branch. For strong growth of the strong branches in the back of the trunk, to provide the next year's backbone branch, so that the first year of dormancy trimming is at least not less than 40% of the total canopy, using strong The local stimulatory effect induces more and stronger developmental branches to achieve the renewal of the strength of the major fruit and vegetative shoots. After the germination of the following year, the north side and the back branch of the new shoots are properly preserved, and the branches do not have to be placed on the back, and the distance is 15 cm or more. The rest of the buds and new shoots are removed as soon as possible. For pruning during the winter, the small and medium-sized branches and long-stemmed strong branches should be drawn at the initial flowering stage, and the angle should be 60-85 degrees. After firmly fruiting in that year, we must promote new shoots while ensuring fruitful growth in the year. In the autumn rainy season, if there is a long period of autumnal shoots, for the newly formed branches, in addition to the short cuts required for individual areas that need to continue to expand, generally do not cut and treat as long as possible. The buds will be adjusted in the coming year. For branches that had retained the results of the previous year, if the surrounding branches did not form and there was a large room for results, they could be retained and continued to be used in the coming year. At the time of the first flowering period after the update, try to make the fruits grow on the new branches that were cultivated in the previous year. The result is that the branch diameter is 0.5-0.6 cm, and the result should be about 15 cm from the branches. After the result, the drooping state of the fruit branches is maintained to ensure excellent fruit quality.

Third, the results of the replacement of the branches

According to the direction of the overall update, after cultivating the updated results in accordance with the above method, the resulting branches will gradually weaken after being used for three years, and generally will be considered for replacement after two years of use.

Large-scale branch renewals: After the second leading branch retraction, when the leader is weakened, alternate branches alternate from the back. As the age of the tree enters the period of full fruition, the tree vigor gradually eases, and the drooping branches are prone to decay, leading the branches to the horizontal direction. When the result is stable, the balance between the stick and the whole can be adjusted according to the updated position of the leading branch, making it oblique or upright. Pomegranate latent buds have a long life and are easy to germinate. Therefore, the cultivation of the lead twigs can be easily performed after the renewal.

Small and medium-sized fruit sticks are updated: In the third year of winter cutting, depending on the specific circumstances, if the branches are weak, the original head can be cut and retracted at the first branch and renewed; if the branches are strong In the growing season, the strong branches on the first branch can be removed in time and the results can be continued using the original head. The purpose of the branch renewal is to rejuvenate. Therefore, when the original leader is not seen debilitating, he must not be eager to update, nor can the leader lead the bushes to death and still not be updated. The correct approach is to make serious judgments by updating the adjustment so that it can maintain a good level of results. The replacement of the entire branch, generally adopts a method of severe retraction to stimulate the base to sprout new shoots, and then grow into new branches according to the former method. Such a cycle to promote strong.
