Pruning method for Carya illinoensis

Abstract

The invention discloses a pruning method for Carya illinoensis. The pruning period can be divided to the resting period pruning and the growing period pruning, the resting period pruning is the pruning executed from the winter leaf fall period to the spring germination period of the next year, and the pruning mode comprises cutting back, thinning and pinching. The growing period pruning can be divided to the spring pruning, the summer pruning and the autumn pruning, the spring pruning is executed from the germination period to the beginning and the ending of the flower season, and the autumn pruning is executed from the young sprout growth stop to the beginning of the dormancy, and the pruning mode comprises bud carving, girdling and ringing, and branch drawing and tip twisting. During the pruning of the early stage, the more principal branches can be kept suitably, and the lower part of the crown can be gradually thinned out. After the Carya illinoensis tree is in the old period, the dead part of the principal branch of the decrepit crown is totally cut off, and the germinated renewal branches are cultivated.

Description

technical field [0001] The invention relates to the field of planting, in particular to a pruning measure for thin-shell hickory nuts. Background technique [0002] Thin-shelled hickory is a plant of the genus Hickory in the family Juglandaceae. It is an ecological and economical tree species integrating high-grade thousand fruits, high-grade woody oil, high-quality hard broadwood and landscaping, and has certain economic, social and ecological benefits. Benefits, broad prospects for development, has developed rapidly in recent years. The propagation of pecan seedlings includes rootstock cultivation and grafting. Pecan has deep roots and is not prone to lateral roots. The traditional field seedling cultivation method has fewer lateral roots and a low survival rate for transplanting. The dominance of the top of the hickory tree is very obvious, the elongation of the vegetative branches is dominant, and the germination rate of the lower side buds is low. In order to shorten ...
