Cuttage Seedling Technology of Blueberry

Blueberry has a unique flavor, which is widely welcomed by people in the market, and therefore has a greater market demand and better development prospects, and in the process of blueberry seedling breeding, cutting is a more common one. So how to cuttage blueberries? Let's get to know it with the editor.

1. Cutting seedling raising time

Generally, the annual twigs are selected from the disease-free and robust mother plant before sprouting in early spring, the branches 30-90 cm long are cut from the middle and lower part of the branches, and then cut into cuttings 13-15 cm long. The cuttings are smooth, the upper incision is a straight incision, the lower incision is an oblique incision, and the lower incision is located below the bud. If the flower buds on the cuttings should be erased in time, on the contrary, if there is no cuttings, they should be discarded. The cut cuttings should be bundled into the moist fine sand and keep the temperature between 2 and 10 degrees.

2. Soil requirements

Blueberry has special habits and strict requirements for the growth environment, especially the root environment, which requires loose, fertile and acidic soil rich in organic matter. It is more strict to the environment in the process of raising seedlings, and the humidity, pH and air humidity of the cutting soil will affect its rooting. The substrate is best to use moss, which has the best water retention and air permeability, and it likes the acidic environment. So the pH value of the substrate should be between 4.5 and 5.2.

3. Cuttage seedling

Before cutting, the cutting nursery bed with a width of 1 meter and a height of 20 to 25 centimeters is determined according to the actual needs of raising seedlings. If possible, the ground hotline can be buried to increase the temperature of the seedling bed and promote the rooting of cuttings. In the cutting can be treated with rooting powder to promote rooting, the cutting depth is generally half of the cuttings or 2/3, the aboveground part of the cuttings should have a bud, cutting should not be a national model, 5 cm X 5 cm is appropriate.

4. Seedling management

After cutting, the seedbed should be kept moist and well ventilated, often sprayed to prevent excessive water loss, causing cuttings to wither and die, but not too much watering to avoid stagnant water, and some to take root and sprout. Keep the substrate temperature between 20 and 25 degrees, which can heal the grafted wound and improve the rooting rate. Before the cuttings take root, there is no need to apply fertilizer. When the top leaves are green, it means that the cuttings have taken root, and thin liquid fertilizer can be applied to promote the growth of seedlings. Do not leave fertilizer liquid in the leaves when fertilizing, so as not to hurt the leaves. Fertilization can spray water on the seedbed and wash away the fertilizer that may exist on the leaves.
