Seedling growing method for increasing robinia pseudoacacia grafting survival rates

Abstract

The invention discloses a seedling growing method for increasing robinia pseudoacacia grafting survival rates. The seedling growing method includes steps of rootstock selecting, branch selecting, scion cutting and processing, grafting, post-grafting managing and the like. A main grafting process includes separating bast of rootstock from wood of the rootstock; inserting scions into the rootstock; binding grafting positions by jute husk; fixing the rootstock and the scions by wet mud; ultimately earthing up the rootstock and the scions by moist and loose soil to form soil piles. The seedling growing method has the advantages that the temperatures and the humidity of contact positions of the rootstock and the scions can be improved, so that healing can be accelerated; combination of the rootstock and the scions can be reinforced, so that the wind-breakage resistance can be improved, the survival rates can be increased by 12% at least, the seedling growing method is easy and convenient to implement, is economical and environmental friendly and has an obvious economic benefit, unbinding can be omitted, the grafting operation labor intensity can be relieved for seedling farmers, and seedlings are convenient to manage; the rootstock and the scions can be healed fast, can be combined with one another firmly and can germinate quickly, the seedlings can neatly come out of the earth, can grow robustly, are high in survival rate and are wind-breakage-resistant, and the seedling growing method is favorable for breeding and popularizing novel varieties of robinia pseudoacacia and has an obvious social benefit.

Description

Technical field [0001] The invention relates to the field of reproduction of Robinia pseudoacacia, in particular to a seedling raising method for improving the survival rate of grafting of Robinia pseudoacacia. Background technique [0002] Robinia pseudoacacia (Robinia pseudoacacia L.) is a high-quality timber forest, firewood forest and shelterbelt tree species in temperate regions. It also has landscape, nectar and feed uses. The traditional breeding method of Robinia pseudoacacia is to use sowing to raise seedlings, but the grafting technology is commonly used in the breeding of good varieties or clones of Robinia pseudoacacia, and the more widely used grafting technology is the cutting seedling breeding technology. Cutting grafting seedlings is often carried out in spring. Due to the large climate change in spring, it is often affected by spring cold, drought, strong wind and other factors after grafting. The survival rate is not high, the emergence of seedlings is late, and...

Problems solved by technology

This method can effectively solve the shortcomings of the traditional grafting method, such as low survival rate, labor-intensive, high cost, and easy wind breakage of seedlings.
