Embodiment Construction

[0022] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0023] A method for shortening the production time of the southern yew seed collection base, which comprises the following steps:

[0024] a. The selection of excellent trees of Taxus chinensis, according to the breeding objectives, in the same-age forests or different-age forests within 2 age classes in the excellent provenance area or suitable provenance area, confirm the excellent trees to enter the peak flowering and fruiting period The best is the best, the ratio of male to female is 4:1, which marks the excellent male and f...

Abstract

The invention provides a method for shortening the building time of a taxus mairei seed collecting foundation. The method is characterized by sequentially including the following steps of a, selection of taxus mairei superior trees; b, identification of the flowering phase of the superior trees; c, trimming of the superior trees; d, root breaking of the superior trees; e, foundation selection; f, foundation planning and preparation; g, seedling lifting of the superior trees; h, configuration of the superior trees; i, planting of the superior trees; j, tending management; k, seed treatment and storage. The large-batch seed production time of the improved variety foundation can be greatly shortened, the initial seed yield of a seed garden is low, the large-batch seed production time is 10-15 years, the large-batch seed production time of a seed production stand is 6-8 years, seed genetic gains are small, after the improved variety foundation is built through the steps, the large-batch seed production time is only 2 years, the seed genetic gains are large, and produced seeds are high in quality and yield.

Description

technical field [0001] The invention belongs to the technical field of breeding of improved tree varieties, and in particular relates to a method for shortening the production time of a southern yew improved variety base. Background technique [0002] Southern yew is a gymnosperm Taxaceae. It is a multi-purpose tree species with national first-class precious protection for wood-skidding, medicinal and ornamental uses. It is mainly produced in the vast areas of southern my country. Sowing and breeding southern yew seedlings has the characteristics of simple breeding technology, low breeding cost, easy mass production, high survival rate of afforestation, and fast growth. It is currently the main way of breeding southern yew seedlings. [0003] At present, the seeds of southern yew mainly come from the wild. With the deep multi-channel development of southern yew and the acceleration of industrialization process, the demand for southern yew seeds is increasing day by day. The ...
