Vegetative propagation method for wild corylus heterophylla hazelnut fruit trees

Abstract

The invention discloses a vegetative propagation method for wild corylus heterophylla hazelnut fruit trees, and belongs to the technical field of fruit tree vegetative propagation. The vegetative propagation method comprises the following steps that a horizontal layering stock plant is selected; branches are treated; cutting slips are treated; a rooting medium is treated; full-illumination spraying cuttage is carried out; and cottage post-management is carried out. A horizontal layering technology and a twig cuttage technology are combined to protect a native plant from being damaged; meanwhile, efficient vegetative propagation is carried out; meanwhile, hormone is adopted to treat the pressed branches to promote branch germination and growth and promote cutting rooting; the proper rooting medium is matched to improve the rooting efficiency; sterilization and insect killing agents are regularly sprayed, and the survival rate of cutting seedlings is improved; and the rooting process is accelerated by adopting the full-illumination spraying cuttage technology. The vegetative propagation method for the wild corylus heterophylla hazelnut fruit trees is easy to operate and high in seedling rate, the problem of vegetative propagation of the wild corylus heterophylla fisch superior line is solved, and a way of becoming rich is increased for fruit farmers.

Description

technical field [0001] The invention belongs to the technical field of asexual reproduction of fruit trees, in particular to a method for asexual reproduction of wild flat hazelnut fruit trees. Background technique [0002] Hazelnut has always been in short supply as a high-grade nut in my country. The main reason is that the main foreign cultivar European hazel (Corylus avellana L.) has poor cold resistance and is not suitable for growing in most parts of my country. The flat hazel (C.heterophylla Fisch.) cultivated in China The hybrid variety (strain) of a fine single plant mixed with hazelnut pollen is called Pingou hybrid hazel (C.heterophylla×C.avellana), also called hybrid hazelnut or hazelnut in production. The suitable cultivation areas are also limited and cannot be widely used. To carry out planting, especially in the cold northern regions, there is still a lack of excellent cold-resistant cultivars, so the local wild hazelnuts are screened for large-fruited, thin-hu...

AI Technical Summary

Problems solved by technology

[0003] The germplasm resources of Corylus in my country are abundant and widely distributed, but restricted by factors such as species, climate and cultivation techniques, most resources are in the wild state, resulting in low yield, poor economic benefits, and late start of horticultural cultivation.

In mountainous areas such as the Changbai Mountains in Northeast China and the Greater and Lesser Xing'an Mountains, wild flat hazel germplasm resources are abundant. Compared with Pingou hybrid hazel, these flat hazels have lower cultivation and management costs and strong stress resistance, and are more suitable for the northern cold regions of Jilin and Heilongjiang. planting, but the current status of hazelnut production in these areas is to pick wild fruits, which cannot be cultivated and promoted, thus forming an industry
