Rapid asexual propagation method for lithocarpus hancei

Abstract

The invention discloses a rapid asexual propagation method for lithocarpus hancei. The method comprises the working procedures of scion collection, grafting time determining, grafting and post-grafting management; particularly, a cork oak container nursery-grown plant is used as a stock, half lignification to lignification branches which are healthy and free of pest and disease damage are clipped from a lithocarpus hancei seed tree to be used as scions, grafting is carried out through a cleft graft method, post-grafting management is carried out, and lithocarpus hancei grafted seedlings obtained in next spring can come out for forestation. The lithocarpus hancei asexual propagation technology is brought through, grafting propagation is carried out through the cork oak stock, the cork oak container nursery-grown plants with the excellent economic characters are greatly and rapidly propagated, and the nursery-grown plant root system is developed. By means of the advantage that the cork oak stock has the high adaptive capacity for natural environment such as drought and barren, the scions and the stock can be rapidly healed, shoots emerge, the shoots rapidly grow, high-quality, efficient and rapid development of lithocarpus hancei is facilitated, and good economic benefits, social benefits and ecological benefits are obtained.

AI Technical Summary

Problems solved by technology

Due to the hard seeds of Acaeaceae, there are many factors in the natural germination process that lead to a low success rate of seed germination, and the natural germination of seeds is far from being able to offset the reduction in resources.

However, in traditional production, the germination rate of the seeds of Fructus aeruginosa without any hormone treatment is often only about 50%, and the germination time is late and the emergence of seedlings is not uniform, which limits the large-scale planting of Fructus fragrans.
