Cutting propagation method of Photinia frondosa

  In the production, Photinia frondosa is mainly used for propagation. The cutting propagation has the characteristics of low cost, simple operation and high survival rate. It can be used in the production of plastic sheds. It is suitable for the promotion and application of most saplings. Let's take a look at it together. Look at the cutting propagation technique of Photinia frondosa!

Cutting preparation of Photinia frondosa

    Select a large-scale drainage, dry ground, low groundwater level, convenient transportation, and a stable water source to build a nursery in the field. Use a single-story shed to cover the greenhouse film, plus a sunshade net, and erect the ground on the ground in the shed. The seedbed can be about 100 cm in width, surrounded by a 10-12 cm high baffle, with a layer of fine sand on the bottom for drainage, the cutting substrate can be made of vermiculite plus peat, or clean yellow soil plus fine sand, seedbed and substrate. Disinfect with fungicides and insecticides to prevent pests and diseases.

    1, cutting time:

    The requirements for the cutting time of Photinia frondosa are different due to the region. The middle and lower reaches of the Yangtze River are better in spring, summer and autumn. Generally, the temperature is between 15 and 35 degrees, and the most suitable is 20-30 degrees. In late April and late June, from late August to mid-October, the golden season of heather is the golden season.

    2, the selection of the cuttings:

    Select the semi-woody annual branch that grows thick and strong to make the cuttings. The cuttings are cut to 3-5 cm long, and the upper and lower cuts are cut flat. In the golden season of cutting, half of the leaves are preserved because of the appropriate temperature. Smaller half, the leaves are slightly more than half, it is more appropriate to pay attention to the stalks moisturizing, shading and watering. It is best to use special scissors when cutting the cuttings. The wounds are smaller than the normal flat-cut scissors, the phloem is cut inward, and the xylem is toward the center. Micro-concave, simple insertion of callus and rooting, high survival rate. Cutting the cuttings and cuttings is best done on cloudy days and at 10 am and after 4 pm.

    3, cutting method:

    The rooting time of the roots of the heather can be used from 40 days to 7-15 days, so the cuttings should be rooted before cutting. The commonly used rooting agents are finished ABT, Guoguang, and biochemical naphthalene acetic acid. Butyric acid.

    Before cutting, the seedbed should be watered, and the cuttings should not be inserted too deep into the soil. Generally, it is 2/3 of the cuttings, 400-700 plants per square meter. The blades at the top of the cuttings should face in the same direction, so that the light is evenly received. Then, it is good for early rooting and early germination. After pouring, the water is poured. After the water of the leaves is dried, it can be sprayed with methyl thiophanate and chlorothalonil 600-800 times. Finally, the whole seedbed is covered with a small arch film. .
