Embodiment Construction

[0083] The preferred embodiments of the present invention are described below. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0084] A method for sowing and raising seedlings of large fruit rose, including the following steps: nursery, seed, sowing, seedling management, bed replacement, nursery, technical file management; its improvements are:

[0085] Seed collection time: due to the different site conditions of the fruit-bearing mother tree, the seed collection time is different every year. Frequent observations should be made during the fruit-bearing period. The collection time of seeds in Jilin Province is from late August to early September. Choose a single plant with strong growth, full fruit and no pests. Plant seeding.

[0086] Seed collection of mother trees: uniform tree crowns, straight trunks, no diseases and insect pests, tree height ...

Abstract

A method for sow and raising seedling of large-fruit rose includes the following steps: nursery, seed, Sowing, seedling management, bed change, nursery, technical archives management, the improvementis: seed collection time: due to the site conditions of seed mother tree, seed collection time is different every year, during the seed period to be observed frequently, seed collection time in JilinProvince is from late August to early September, should choose strong, fruitful and free of disease and insect pests single plant to collect seeds. The invention solves the technical bottleneck of accelerating germination of wild seeds, realizes the emergence rate of more than 85%, and the seedlings can safely survive the winter without protective measures through the research work of sowing and breeding wild large-fruit rose, seedling growth rhythm and adaptability investigation, excellent germplasm gene preservation and the like, and carries out systematic experimental research for many times. It fills in the blank in the breeding technology of this species and lays the foundation for breeding the stable line of Hunchun big fruit rose.

Description

Technical field [0001] The invention relates to a method for sowing and raising seedlings of large fruit roses. Background technique [0002] Rosa rugosa Thunb (Rosa rugosa Thunb) is a plant of the genus Rosaceae. Native to northern China, North Korea, Japan and the Russian Far East. Since the last century, due to the interference of natural forces and human activities, the habitat of the wild rose has changed. Its distribution area is gradually shrinking and fragmenting, and the population size is also decreasing year by year. At present, the only wild natural distribution area in the country is also limited to the vicinity of the border between China and North Korea in Hunchun, Jilin Province, and the number is rapidly shrinking and decreasing, entering an endangered state. In 1992, this species was listed as a national second-level protected plant and was included in the "Red Book of Chinese Plants" as an endangered plant. [0003] The "Technical Regulations for Sowing and R...
