Asexual rapid propagation method for lithocarpus amygdalifolius

Abstract

The invention discloses an asexual rapid propagation method for lithocarpus amygdalifolius. The method comprises the steps of: scion collection; grafting time; grafting; and post-grafting management. The method specifically comprises: selecting a quercus variabilis container seedling as a rootstock; clipping robust and pest-free branches which are from being semi-lignified and lignified from a seed tree of lithocarpus amygdalifolius as scions; performing grafting by adopting a cleft grafting method; and performing post-grafting management till grafted seedlings of lithocarpus amygdalifolius obtained in spring in the next year can be discharged out of a garden for afforestation. The method disclosed by the invention is a breakthrough of an asexual propagation technology for lithocarpus amygdalifolius. By performing propagation by grafting by using the quercus variabilis rootstock, quercus variabilis container seedlings which maintain excellent economical character of a mother parent are massively and rapidly propagated, and the root systems of the seedlings are developed. By virtue of the advantageous characteristic that the quercus variabilis rootstock has a relatively strong adaptive capacity to natural environments such as drought and barren environments, scions and rootstocks of the lithocarpus amygdalifolius seedlings can be quickly healed and germinate new tips, and the germinated new tips are quick to grow, so that high-quality, high-efficiency and quick development of lithocarpus amygdalifolius are accelerated. The preparation method has relatively good economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for rapid vegetative propagation of Apricot chinensis. Background technique [0002] Apricot leaves ( Lithocarpusamygdalifolius (Skan) Hayata ), also known as Lithocarpus apricot leaf, red peony, and Lingmei, is an arbor of the genus Lithocarpus in the family Fagaceae. The new branches and young leaves extracted in spring and summer are densely covered with yellow-brown curly pilose, and all the hairs fall off after autumn . Male spikes axillary in single spike or multiple spikes arranged in panicles, rachis densely pilose; female flowers in clusters of 3, sometimes scattered single. The cupule is nearly spherical, full of nuts, in a discontinuous ring; the wall of the nut is slightly thicker than that of the cupola, and the top of the nut is puberulent. Distributed in central and southern Taiwan, southern Fujian, southeastern Guangdong about south ...

AI Technical Summary

Problems solved by technology

Since the seeds of Xingyeke are hard seeds, 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 less than the reduction in resources

However, in traditional production, the germination rate of Apricot foliage seeds without any hormone treatment is often only about 50%, and the germination time is late and the emergence of seedlings is irregular, which limits the large-scale planting of Apricot foliage
