Leave a trunk, then trim it according to its own growth and development characteristics to form a reasonable skeleton. Generally, there are three tree types, namely, less trunk, single trunk and more trunk. The trunk is less clustered; Leave 3-4 basic branches as main branches and extend obliquely in different directions. The main branch bears lateral branches, which bear vegetative branches and fruiting mother branches. The whole tree is still happy,

The stem shape is simple; This tree should keep a trunk, select 3-4 evenly distributed main branches on the trunk, select side branches on the main branches, and plant secondary branches and fruiting mother branches on the side branches to form a short trunk.

Multi-stem cluster; In this crown shape, 3-4 basic branches are selected as main branches and the rest are cut off from the base. If the number of basic branches is less than the number of main branches, you can choose from budding branches. After selecting the main branch, cultivate the fruiting branch and vegetative branch.

5. How to apply fertilizer Apply decomposed farmyard manure in early May and topdressing compound fertilizer in mid-July. Planting in the second year, topdressing can be projected outside the crown, not too deep.

A long-term prosperity project of planting hybrid hazelnuts on trees and propagating seedlings under trees, with a one-time investment of 50 years, will benefit from 100 years. The cold-resistant seedlings of large-fruit hybrid hazelnut are sold in the field, and special breeding procedures and new cultivation techniques are adopted, so the cultivated hazelnut seedlings have more roots and the planting survival rate is over 99%. Hybrid hazelnut has almost no pests and diseases, which has little effect on its growth.
