The latest course on the Technical method of High connection of Pear trees

Pear trees are widely distributed in China, and there are many varieties, many people are not sure about the varieties when planting pear trees, and find that the varieties are not good when waiting for the results, so it is time-consuming and laborious to replant them, so the high grafting technology arises at the historic moment. The so-called high grafting is to change the head at one time by using the skeleton of the pear tree and the combination of long and short scions, so that the low-yield trees can also get high yield. So how do you do it? Come and have a look with the editor.

1. Preparation before high contact

When preparing for high grafting of pear trees, we should strengthen fertilizer and water management one year in advance, strictly prevent diseases and insect pests, and try our best to improve the tree potential of pear trees. In high grafting, it is best to set and prune the plant, pruning 2-3 days before grafting, thinning the excess backbone branches and auxiliary branches, leaving 20-30 cm short section of the main branches and side branches as the anvil pile. Leave an anvil pile according to 15-20 cm and graft alternately on both sides of the plant to the top 1 cm.

2. Master the grafting period

Grafting is usually in the time when the sap begins to flow but does not sprout, which is about March-April. If the budding method is adopted, it can be carried out from June to August.

3. Scion treatment

Scions must choose excellent varieties with high quality, large fruit, beautiful appearance and suitable for local planting. These varieties should be obtained from strong mother plants, and one-year-old robust vegetative branches or fruiting branches with full development and full buds around the crown should be selected to collect scions. The scion used for branch grafting in spring can be pruned in winter, the fully developed annual branches can be collected, tied up according to the variety and buried in the cellar or ditch hole for storage. in addition, a layer of fine sand needs to be laid at the bottom. Humidity should be held in a ball without dripping, and the hands should be loosened.

4. Post-season management

High grafting can be solved by many methods, such as grafting, embedded bud grafting, bud grafting, abdominal grafting and so on. Each grafting method has its own advantages, and the common grafting method is branch grafting, which can be carried out before sap flow. After grafting, the management must be strengthened in order to obtain a better survival rate of grafting, such as fertilizer and water management, flower and fruit management, plastic pruning and so on.
