Breeding and rapid expanding propagation method for new variety of scutellaria strigillosa in saline-alkaline land

Abstract

The invention discloses a breeding and rapid expanding propagation method for a new variety of scutellaria strigillosa in saline-alkaline land. The method comprises the following steps: planting collected scutellaria strigillosa germ-plasm resources in the saline-alkaline land; preparing rooting solutions of different concentrations and proportioning ratios; investigating whether mutated branchespresent in a scutellaria strigillosa planting area or not; carrying out marking and subjecting part of the branches to asexual propagation if the mutated branches present; carrying out mutant character observation on asexual-propagated plants obtained according to primary selection, and subjecting plants of stable inheritance to expanding propagation of continuous 3 generations and carrying out recording; and carry outing an investigation on expanding-propagated plants obtained according to reselection, and determining that the expanding-propagated plants are a new variety if the expanding-propagated plants continuously maintain mutant characters. According to the method, the breeding method for the new variety of the scutellaria strigillosa in the saline-alkaline land is established through observing mutant-character branches of the scutellaria strigillosa caused by spontaneous mutation in the saline-alkaline land and using methods such as asexual propagation and stability observation; and the method has the advantages that the breeding technique is simple, the workload of breeding is reduced, and the progress of breeding is accelerated.

Description

technical field [0001] The invention relates to the technical field of breeding and propagation of Scutellaria baicalensis, in particular to a method for breeding new varieties of Scutellaria baicalensis and rapid propagation on saline-alkali land. Background technique [0002] At present, the saline-alkali soil improvement project nationwide has achieved certain results. In order to realize the sustainable use of land resources and develop a new model of coastal saline soil improvement, people consider using biological measures to improve coastal saline-alkali soil, which can not only save costs, but also fully Excavate local resources and receive better improvement effects. [0003] Studies have shown that planting saline-alkali-tolerant plants can effectively promote soil desalination, improve soil structure, and increase soil fertility. In addition, planting plants can enhance vegetation transpiration, lower groundwater levels, delay or prevent salt accumulation and ret...

Problems solved by technology

However, at present, the artificial introduction and cultivation technology of Scutellaria baicalensis has not yet formed a system, and there are no relevant records about the artificial cultivation of Scutellaria baicalensis. In order to protect Scutellaria baicalensis and use its characteristics to improve the soil structure of saline-alkali land, it is urgent to develop artificial cultivation techniques
