Wild gymnocarpos przewalskii introduction, domestication and breeding method

Abstract

The invention discloses a wild gymnocarpos przewalskii introduction, domestication and breeding method. The method comprises the following steps of 1, collecting seeds; 2, raising seedlings; 3, transplanting the seedlings; and 4, performing screening and popularizing. In the first step, in the middle ten days and the last ten days of July, gymnocarpos przewalskii which grows vigorously, is free of plant diseases and insect pests and has larger and many calyxes nearby the Anxi extreme arid desert national nature reserve are collected together with sandy soil after the calyxes fall off naturally; and according to the method, domestication and seedling raising are conducted by simulating the growth environment of soil, temperature, illumination conditions and the like, the best growth condition, growth environment and cultivation technology can be explored for breeding and popularization, artificial breeding of rare and endangered national first-level protection plant gymnocarpos przewalskii is promoted, and an artificial nursery stock method is provided for gymnocarpos przewalskii protection and breeding. Meanwhile, in the breeding process, the natural growth environment is fully simulated, the survival rate of gymnocarpos przewalskii is increased, and large-scale popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for introducing, domesticating and breeding wild nudibranchs. Background technique [0002] Naked fruit tree, also known as achene dianthus, caryophyllaceae, is one of the rare and endangered plants, a relatively rare tertiary relic plant in central Asia, a unique plant in the desert area of ​​central Asia, and one of the main construction species of gravel deserts , is also a national first-class protected plant, and belongs to the ancient Mediterranean flora. Its survival and evolution can reflect the vicissitudes of the ancient Mediterranean climate and the drought evolution process of plants since the Tertiary. It is very important for the study of desert occurrence in Northwest my country , development, climate change and the origin of xerophytic flora components are of great scientific value. Bare fruit trees have the characteristics of drought resista...

Problems solved by technology

In the case of difficult natural reproduction, several scholars have carried out introduction and breeding and research on asexual cloning, but due to the limited diffusion range of cloned offspring, they are often concentrated around the mother plant, resulting in a limited effect of fierce sibling competition on population reproduction, so It is not as effective as seedlings in spreading distance, producing offspring, and adapting to evolution, and asexual reproduction and germinated seedlings encounter water shortage, and it is very difficult to survive continuous drought
