As an important economic forest fruit, the tree shape management of fruit trees is very important for the quality and yield of fruits.
In the open-field orchard, the three-main branch open-hearted tree management method can effectively guide the growth of economic forest fruit and improve the yield. This article was written by Jiang Shaolong, a senior agronomist in Laocheng Township, Yuanmou County, and explained as follows, how to implement the three main branches of happy tree shape management and related technologies for economic forest fruit pruning.
01. Choose the right main branch, after the fruit tree is planted, first of all, you should choose three main branches that grow evenly.
At a distance of 40 to 50 cm from the ground, cut the fixed stem, then leave 7 or 8 buds within 20 cm below the fixed mouth, the rest should be removed.
The selection of the three main branches of fruit trees should consider their growth uniformity, orientation and staggered arrangement up and down to make full use of light.
02. Control the growth of branches.
The annual growth of economic forest fruit is large, there are many branches, more than 20 branches can be branched a year, and can germinate secondary branches, tertiary branches, and grow rapidly.
Therefore, after pruning this winter and next spring, it is also necessary to prune in summer to improve the internal light, control the growth of ineffective branches, and promote the formation of flower buds on effective branches as soon as possible, so as to achieve a balanced tree potential.
03, pruning this winter and next spring, in this winter and next spring, it is essential to prune the main branches. Usually, it is necessary to prune about 1 3 or 1 4 at the end of the main branch, but be careful"Heavy pruning of strong branches and light pruning of weak branches"principles.
At the same time, it is also important to pay attention to the basal angle of the main branch, which should be kept between 45° and 60° to promote uniform growth.
04. Cultivate side branches, in order to increase the yield, two side branches can be cultivated in the second year. These two lateral branches should be relatively even, about 50 60 cm away from the main branch, staggered from each other, which is conducive to ventilation and light transmission.
Through the above three main branch heart-shaped tree management methods, the yield and quality of economic forest fruits can be effectively improved, and the healthy growth of trees can be contributed. This kind of fruit tree shape management technique is an important guide for fruit tree growers, writer: Jiang Shaolong.
