Therefore, after selecting the main branch and lateral branch, the extended branch is light and short, and the branch length of 1/3 is cut off, and full buds and lateral buds are cut off. Young trees and early fruit stage should be lightly pruned, full of buds, promoting multi-branching, expanding crown as soon as possible, forming tree skeleton, making it form flower buds and increasing yield.
When the fruit is full, it is mainly pruned lightly, and the main and lateral branches at all levels are light and short, with buds and lateral buds left at the cut. The crown continues to expand because it is still in the young tree stage, and the tree grows vigorously.

Growth habit
Hazelnut has strong adaptability to soil, and can grow, develop and bear fruit on light sandy soil, loam, light clay and light saline-alkali soil, but the most suitable soil is sandy loam. The soil layer is more than 50 centimeters thick. It has strong adaptability to soil and acid-base soil, and can grow and bear fruit normally in the range of pH 5.5-8.0.
The depth of root system planting should not be too deep or too shallow, and the rhizosphere should be flat or slightly lower than the ground 5 cm after planting. The buried depth of soil above rhizosphere is 6- 10 cm. If the soil in the cave is loose, to prevent the soil in the cave.
Hazelnut is a light-loving plant, and it is best to cultivate it in the leeward and sunny places. In warm and sunny places, high yield comes early. However, under the mountain slope of 15, any slope direction can be cultivated. Annual illumination of more than 2000 hours can meet the requirements.
