Shaping and pruning of green peach
Plastic types of green peach
1. Natural cup shape: in the second or third year after the survival of grafted seedlings, plastic surgery should be carried out in combination with colonization p>
First, select and retain a sufficient number of main branches with balanced growth, cut them short, and pick the heart in summer to promote the growth of branches, so as to form a perfect and elegant tree structure in a short time. Do a good job in the foundation of plastic surgery p>
Secondly, the fixed drying should be about 40 cm to 100 cm high; There are three to five main branches. The length and thickness of the main branches are either close to rotation, and then the main branches are intercepted. The length should be between 40 and 60 cm; The lateral branches and main branches are selected and retained in the same direction, and there are many large branch groups on the back p>
Finally, the tree structure to be trimmed is: the crown is complete and presents a round head shape p>
2、cliff shaping
First of all: select and keep two main branches growing in the opposite direction, and the main branches growing in the lower part. The base angle of the main branches should be large. The specific angle can be determined according to the terrain. Pay attention to cutting at the full bud to promote growth p>
Secondly, the other main branches should be re cut, and the selected base angle should be small, or they should be cultivated into a relatively large branch group, so as to form a tree shape inclined to the horizontal or low p>
Finally: according to the above steps and operations, cliff shaping will be a great success p>
Different shaping methods should be adopted in different growth stages
Early viewing stage
During this period, green peach has sufficient nutrition, vigorous growth, easy to grow branches and small branching angle. According to the characteristics of weak dryness and strong positive tree species, it is most suitable to carry out fixed drying and selection and retention of main branches in winter p>
When summer comes, you can trim, pick the heart or tie it, so as to form a perfect tree shape in a short time p>
Best viewing period
During this period, the tree crown basically forms to the tree body and begins to age. At this time, the tree crown gradually expands, the growth becomes vigorous, and the flowering is also lush. There are urgent requirements for soil, fertilizer and water. We should pay attention to the renewal of branch groups and the supplement of nutrients p>
During this period, the old branches should be cut out and the redundant tree crown should be cut out and trimmed to ensure the growth of the prototype and promote the growth of new branches< span>
