1, seedling stage: Pruning peach trees at seedling stage should adopt the method of picking the heart and topping, cut off the buds and leaves at the top of peach branches with sterilized sharp scissors, shorten the long branches by one third, control the height of plant shape, and promote the peach trees to sprout new branches and bear fruit.
2. Early fruiting period: After peach trees enter the early fruiting period, they should give priority to shaping and cut off too messy and dense branches to improve the light transmission and ventilation between trees. Then the branches and leaves of peach trees suffering from diseases and insect pests should be cut off and burned to avoid affecting the growth of plants. After pruning, spray carbendazim on the wound for disinfection.
3. Complete fruiting period: When the peach tree is in the complete fruiting period, the pruning method should be adopted, and the branches with poor growth and poor growth should be cut off to concentrate nutrients on healthy branches, and then the dry dead branches and damaged branches on the peach tree should be cut off from the base to reduce the consumption of nutrients.
Grafting method of peach tree
Seedlings of Prunus armeniaca or Prunus persica (rootstock) are mostly used for propagation, and the survival rate of branch grafting and bud grafting is high.
Grafting: March when the buds have begun to sprout. Cutting is commonly used, and it is better to use one or two-year-old seedlings as rootstocks.
Bud grafting: it is carried out in July and August, and "D" grafting is often used. Rootstocks should be full-year-old seedlings.
