Propagation method of purple leaf plum: budding method

select the appropriate rootstock, you can use the seedling of purple leaf plum or peach, mountain peach, peach, apricot, mountain apricot, plum, plum, etc. In contrast, the growth momentum of Peach Rootstocks is sufficient, and the color of leaves is purple-green, but they are afraid of waterlogging; Apricot and plum have a long life, but they are also afraid of waterlogging; Plum rootstock is more waterlogging resistant. Apricot, peach and mountain peach are the most common rootstocks in North China the grafted rootstock is generally two-year-old seedlings, preferably specially for rootstock culture. Before grafting, it should be cut short, leaving only 5-7 cm stumps on the surface. In the middle and late June, the bud position should be set on the branches selected for scion, and the buds should be full without dry tips, diseases and pests cut the xylem obliquely upward at an angle of 30 degrees at 2 cm below the bud position with a sterilized knife until it is 1 cm above the bud position, then cut a knife horizontally at 1 cm above the bud position, gently remove the connecting bud, and then cut a "t" cut on the bark at 3 cm from the Rootstock to the ground, so that the rootstock and the connecting bud can be closely combined, and then bind it with plastic tape. The buds do not wilt for about 7 days, indicating that they have survived. The plastic belt can be removed in about 25 days

Propagation method of purple leaf plum: cutting method

1. Cuttings preparation

in late autumn, cut the current year's branches without diseases and insect pests from robust trees, or combined with plastic pruning, cut the branches with plump and strong buds without diseases, insect pests and mechanical damage into 10-12cm branches as cuttings, and 3-5 buds are better

2. Nursery land selection and land preparation

the nursery land should be a place with convenient drainage and irrigation and transportation, and the soil layer should be fertile, loose and deep sandy loam. Before land preparation, it is necessary to apply fertilizer and sterilize the soil. Then carry out deep ploughing, fine raking, leveling the land, and then remove weeds, waste agricultural film and other sundries to make a border

3. Cutting time

from late November to mid December

4. Cutting method

cut the lower part of the cuttings close to the bud into a smooth slope, and insert the slope of the cuttings downward into the soil. After cutting, drain water and irrigate immediately. When the soil is slightly dry, it can be covered with double-layer plastic film for thermal insulation. At the same time, in order to keep warm, a 1m high plastic arch shed needs to be built on the border surface to wait for the emergence of purple leaf plum

Propagation method of purple leaf plum: high altitude strip pressing method

1. Branch selection

plants with strong tree potential and no diseases and pests should be selected for branches. The diameter of branches is usually 1 ~ 2 cm, and 2 ~ 4-year-old branches are better

2. Strip pressing operation

the pressing strip is carried out from mid April to mid May in spring. Select the appropriate part on the pressing strip and cut two notches with a grafting knife, with a spacing of about 1.5cm. Then peel the skin between the notches, put on the plastic bag immediately after the peeling, and tie the plastic bag at the lower part of the lower notch. Then put the mixed sandy loam mud into the bag and pinch it into a ball. The mud ball needs to wrap the peeling part and make it in the middle of the mud ball, Fasten the top of the plastic bag

3. Late governance

when the plastic bag is sealed, always check whether the mud ball is dry and hard. If the soil ball is soft, it indicates that the binding effect is good and the soil moisture content is high. About 45 days later, the wound healed and began to take root. At the end of autumn, the pressing strip was cut at the lower part of the mud ball for transplanting. If the soil ball is dry and hard, it means that the plastic bag leaks air. Inject water with a syringe immediately, and then put another plastic bag outside the plastic bag
