Method for improving yield and quality of dendranthema morifolium cutting by utilizing grafting

Abstract

The invention provides a method for improving the yield and quality of a dendranthema morifolium cutting by utilizing grafting, belonging to the technical field of floriculture production. The method comprises the following steps: preparing a rootstock; preparing a scion; grafting and managing; and collecting the cutting. Compared with the currently adopted method in which a cutting seedling is utilized as a scion mother tree, the method provided by the invention has the advantages that the grafting seedling is utilized as the scion mother tree, the growth is vigorous, and the high-yield high-quality cutting can be obtained. In each scion batch, compared with cutting seedlings, cutting yield, average length, average node number, average thickness, average fresh weight and average dry weight of the artemisia scoparia grafting seedling are improved. Furthermore, the cut rooting capability of cutting is improved, the earliest rooting days, the number of adventitious roots, the root length, the root thickness, the root system dry weight and other indexes of cutting rooted seedling are higher than those of the cutting seedling.

Description

technical field [0001] The invention belongs to the technical field of production of flower seedlings, and in particular relates to a method for improving the yield and quality of cut chrysanthemum cuttings by grafting. chemical production. technical background [0002] chrysanthemum( Dendranthema × grandiflora Tzvel.) is a perennial herb of the genus Chrysanthemum in the family Asteraceae. Cut chrysanthemum is one of the four major cut flowers in the world. Its production and sales of cut flowers rank second in the world, and it occupies an extremely important position in the flower industry. Cuttings have a high propagation coefficient and can maintain the excellent traits of the species, and have become the most important propagation method for the large-scale production of cut chrysanthemums. However, the cutting quality and yield of chrysanthemum ear-picking mother plants are easy to decline after repeated ear picking, and the mother plants need to be re-cultivated, ...

AI Technical Summary

Problems solved by technology

Relevant studies and production practices have confirmed that grafting can effectively improve the growth potential and resistance of horticultural crops, but using Artemisia plants as rootstocks to graft cut chrysanthemums as mother plants for ear picking can prolong the ear picking time of the mother plants and increase their yield and yield. There is no relevant research and practice on quality
