The pruning of pear trees is an important measure in cultivation management and it is also a very detailed work. Plasticity is based on pear growth habits, growth patterns, site conditions, and other characteristics of cultivation and management. Pruning is based on plasticity. Continue to cultivate and maintain high-yielding tree structure, regulate growth and balance of results to maintain pears. The trees are of high quality and yield for successive years. Plastic and pruning must be coordinated with comprehensive management of soil, fertilizer, and water, and comprehensive pest control, in order to give full play to their role in increasing production.

Plastic surgery and pruning are indispensable technical measures in the cultivation and management of pear trees, and they are also irreplaceable by other technical measures. However, they are by no means omnipotent or unique, and must be properly treated and applied. If one-sided emphasis on the role of pruning, while ignoring other technical measures, or the pruning and other technical measures against the excessive; emphasis on the tree, pruning and pruning; or do not pay attention to pruning, can not fully play the role of plastic pruning, and Obtaining early fruit, high quality, high yield, and high efficiency will result in late saplings, poor tree production, poor quality, and short economic life.

1, pull the stick:

It is very important for pears whose growth habits are more upright. Generally, the branching angle is increased by pulling, supporting, and hanging branches around July to adjust the angle required for cultivating trees. The main lateral branches must be timely and not allowed to delay the season. Otherwise, the workload of adjusting trees in the future is too large and the tree shape cannot be standardized.

2, ring 刈 (peel):

It is usually carried out on main branches, side branches and leggy branches. The ring should be 2-3 rings with a spiral ring. When girdling, it is necessary to strictly control the stripping width and not to damage the xylem. The width should be within 1/10 of the diameter of the twigs, and the width should not exceed 1.0 cm. From May to July, too late is not conducive to wound healing. After peeling, it can be wrapped with plastic film for healing. The girdling has great harm to the tree vigor. It is recommended to use a ring cut to smear Huanuo No. 2. It has no side effects on the tree body and can promote flower and fruit protection.

In the pruning process of pear trees, no matter what kind of pruning method is adopted, the comprehensive response must be taken into account in order to achieve the intended purpose. Before pruning a pear tree, first observe the age and strength of the tree, how much it takes, and so on, in order to determine what pruning method should be adopted. In general, the amount of pruning should be lighter for saplings and trees and small numbers of flower buds, and for mature trees, weak trees, and especially flowering trees, the amount of pruning should be moderate some.

Pear scab, black spot, ringworm disease, pear nettle, pear leaf acerb, and wood alder are the main diseases and pests that cause early defoliation. In addition, one-time picking is also one of the causes of early defoliation. Premature defoliation is the main reason for the secondary flowering of pears. To prevent secondary flowering, attention should be paid to picking fruits in batches, supplementing fertilizers in time after harvest, strengthening pest control, and strengthening dry season irrigation and tree cover.

Amino Acid

Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
