How to propagate blueberries by cuttings? Latest technical method tutorial
Blueberries are surely quite familiar to everyone, and our country now has a very large planting area. Blueberries are very nutritious and beneficial to human health. As the demand for blueberries grows larger and larger, many growers also want to expand their planting area. Expanding the planting area is mainly done through cutting propagation, so how should it be done? Below, the editor brings you the cutting propagation technique for blueberries, let's take a look!
1. Seedbed preparation
First, we need to choose river sand, peat and other materials as the substrate soil for the seedbed, but if river sand is used alone, transplanting is required, which is rather troublesome and will also affect the growth of blueberries to some extent. Therefore, the culture soil is mainly a mixture of river sand and peat. The blueberry seedbed can be made in the open field, evenly placing the prepared substrate into the seedbed, and controlling the area of the seedbed according to the planting quantity. However, in this way the rooting rate is relatively low, so if conditions permit, wooden raised beds can be built, keeping a certain distance from the ground to increase temperature and rooting rate.
2. Selection of cuttings
Cuttings should be selected from robust blueberry trees free of pests and diseases. On the blueberry tree, choose thick, mature branches, and do not choose branches that are too long, too dense, or frost-damaged. If pests or diseases have occurred, the mother plant selected should be far away from diseased fruit trees. The length of the cuttings must not be less than 15 cm, and the growth time should preferably not exceed 1 year. If there are no ideal cuttings, flower bud branches can be chosen, and the flower buds can simply be removed at the time of cutting. However, the quality of flower bud branches is relatively poor, the rooting rate is low, and the growth ability of the resulting fruit trees is not very strong, so flower bud branches should be used as little as possible.
3. Pruning at the right time
The pruning time is determined according to the seedling requirements. When the number of seedlings to be raised is small, it is usually done in March, and after pruning the cuttings must be inserted into the soil immediately. On the contrary, if the number of seedlings to be raised is large, the new buds on the branches need a certain accumulation of low temperature to sprout, so to ensure the branches have sufficient low-temperature accumulation, pruning needs to begin around February each year. The pruning time is very important for the growth of blueberries. After selecting the branches, management of the branches should be strengthened to prevent mechanical wounds or the occurrence of pests and diseases, otherwise the original cutting plan will be disrupted.
4. Cutting at the right time
When cutting the branches, choose the cutting tools well and make sure the tools are sharp enough to prevent uneven cut surfaces. Keep the cuttings for propagation at about 9 cm. The cut above the soil should be flat and small, while the cut within the soil should mainly be a slanted cut, which can increase the rooting rate of the branches. Then place the slanted cut part in river sand for storage. When ready, water the seedbed thoroughly, but not too much. Then insert the branches vertically into the seedbed, controlling the density well and not making it too dense. This prevents it from affecting the growth of blueberries after rooting and from worsening the harm of pests and diseases. Strengthen management after cutting to ensure the survival rate.
The above is a brief introduction to the blueberry cutting propagation technique. After cutting, management work should be done well, and fertilizer and water application should be strengthened to prevent poor nutrition from affecting growth. After rooting, transplant appropriately according to the growth of the branches. For specific management methods, you can enter the website to view related articles!
