Apple heart-picking methods and matters needing attention

In the process of apple production, the commonly used technical measures are mainly to stimulate lateral bud germination of new shoots and to increase the number of branches of the whole plant, which is a measure to increase apple yield. So when is the apple heart picked? How to pick the heart? These are all what many friends want to know, so let's take a look at them with the editor.

1. Apple heart-picking time

Apple coring can be carried out throughout the growing season, but because of the high temperature in summer and the large growth of apple branches and leaves, it is very easy to germinate dorsal branches and overgrown branches, so it is necessary to carry out coring throughout the summer. The coring time should be determined by the degree of Lignification of the new shoots. Generally, when the new shoots grow to about 15 cm, in order to control the vigorous growth of the new shoots and promote the formation of flower buds, 3-5 cm coring should be left at the base. About one month after the first coring, when the secondary shoot grows to 15 cm, the second coring can be carried out, and then the coring can be carried out according to the plant growth potential. For the varieties with strong growth, the coring can continue until the later stage of growth.

2. The method of picking out the heart

Picking the heart should first aim at the upper back branches and overgrown branches of fruit trees. if the overgrowing upper back branches and overgrown branches are not controlled in time, they will become invalid branches that affect light. After coring in summer, it promotes the formation of medium and short branches, which can cultivate a compact fruiting branch group, which is about 5cm removed when the new shoots are semi-lignified, and the formation rate is the highest. The second is to coring the extended branches of young trees. some young trees have a large growth, and the extended branches can grow to about 1 meter in a growing season. At this time, coring can be used to promote secondary branch shaping, speed up the formation of tree crown and increase the number of branches of the whole plant. The heart of the extended branch is usually picked in June, and the interception length is about 40 cm, which usually needs to be carried out every other year. Finally, there is the fruit moss branch, which can not only increase the number of branches, but also promote the compactness and fullness of the branches, and inhibit fruit drop at the same time.

3. Matters needing attention

The effect of coring on young trees is obvious, and repeated and simple, very easy to do, without too much technology, but also pay attention to the time, otherwise not only can not achieve the desired, but also affect the growth of plants. If the heart is picked too early, the germinated secondary branches will continue to adjust and play a role in inhibiting growth, while too late can not promote more secondary branches. In addition, according to different tree age, different growth, different management and climate characteristics, we should determine the appropriate time to pick the heart, and we can take measures to pick the heart many times when necessary.
