Artificial cuttage breeding method of wild Rosa odorata var. gigantea

Abstract

The invention relates to an artificial cuttage breeding method of wild Rosa odorata var. gigantea. The method comprises the following steps of: selecting a wild Rosa odorata var. gigantea tree which grows for 3-5 years and has favorable development of a tiller branch of the root and stem part as a female parent material; cutting the lignified or semi-lignified raw branch in the current year, which is the stem and root part and is not budded, as a fringe; selecting the tip part and middle section part of the fringe for manufacturing inserted fringe; carrying out right-angle cutting on an uppernotch in the cutting position, wherein a lower notch is an inserted fringe base notch; carrying out slope cutting and cleaning disinfection on the node and soaking the node in a root growing powder accelerating agent aqueous solution, and then inserting into a seedling bed according to the plant row space of 30cm*10cm; and after growing and budding the inserted fringe, withdrawing a sunshade screen and entering a natural growth phase. The method disclosed by the invention is simple and convenient and has low cost; on one hand, the method provides sufficient raw material guarantee for the production of a pharmaceutical enterprise and realizes the scientific utilization of plant resources; on the other hand, the method protects wild resources and ecological environment and has favorable market application prospect.

Problems solved by technology

[0003] As the market demand for Changshu Tablets and Changshu Capsules continues to increase, the number of roots of Gungonia quinquefolius is also increasing. Long-term excavation has led to a decrease in the distribution area of ​​wild Ginkgo fruit, and damage to wild resources and the ecological environment. Seriously broken

In order to meet the protection of the raw material supply and the natural environment to the root of the fruit of the fruit, vigorously develop the artificial propagation method of the fruit of the fruit and become an urgent problem to be solved, but there is no successful report in the prior art
