The latest course on cutting propagation techniques of blueberry

Blueberries must be familiar to everyone, our country now has a large planting area. Blueberries are very nutritious and beneficial to human health. With the increasing demand for blueberries, many growers also want to expand their acreage. The expansion of planting area is mainly based on cutting propagation, so how to carry out it? The following editor brings you the cutting propagation technology of blueberries, let's have a look!

1. Seedbed preparation

First of all, we have to choose river sand, peat and other substances as the substrate soil of the seedling bed, but if we use river sand alone, we need to transplant, which is more troublesome and the growth of blueberries will be affected to a certain extent. Therefore, the cultivated soil is mainly mixed with river sand and peat. The blueberry seedbed can be carried out in the field, put the prepared matrix evenly into the seedbed, and control the area of the seedbed according to the planting quantity. However, in this way, the rooting rate is low, so if possible, wood can be used to build a bed, keep a certain distance from the ground, and increase the temperature and rooting rate.

2. Selection of cuttings

Cuttings should be selected on robust, pest-free blueberry trees. Choose sturdy and mature branches on blueberry trees, not too long, too dense and freeze-damaged branches. If there is a phenomenon of diseases and insect pests, then the mother plant should stay away from the diseased fruit trees. The length of cuttings should not be less than 15 cm, and the growth time should not exceed 1 year as far as possible. If there is no final cuttage, you can choose the flower bud branch and erase the flower bud when cutting. However, the quality of flower bud branches is poor, the rooting rate is low, and the growth ability of fruit trees is not very strong, so flower bud branches are used as little as possible.

3. Timely pruning

The pruning time is determined according to the seedling requirements, when the number of seedlings is small, it is usually carried out in March, and should be inserted into the soil immediately after pruning. On the contrary, when the number of seedlings is large, the new buds of branches need to accumulate at a certain low temperature, so it is necessary to start pruning around February every year to ensure that the branches have enough low temperature accumulation. Pruning time is very important for the growth of blueberries. After selecting the branches, it is necessary to strengthen the management of the branches to prevent mechanical wounds, or the occurrence of diseases and insect pests, otherwise it will disturb the original cutting plan.

4. Timely cutting

When cutting branches, you should choose a good cutting tool to ensure that the tool is sharp enough to prevent the cutting incision from being uneven. The branches of the cuttings are kept at about 9 cm. The notch in the upper part of the soil should be flat and small, and the cut in the soil should be mainly oblique cutting, which can improve the rooting rate of branches. Then put the oblique cut place in the river sand for storage, after the preparation, pour enough water on the seedling bed, but not too much. Then the branches are inserted vertically into the seedbed to control the density and not to be too dense. Prevent the growth of blueberries after rooting and aggravate the harm of diseases and insect pests. Strengthen the management after cutting to ensure its survival rate.

The above is a brief introduction of blueberry cutting propagation technology, after cutting to do a good job of management, strengthen the application of fertilizer and water, to prevent malnutrition affecting growth. When rooting, according to the growth of branches and then appropriate transplanting, specific management methods can go to the website to view the relevant articles!
