Method for promoting germination of polygonatum cyrtonema seeds

Abstract

The present invention relates to the technical field of plant cultivation and particularly to a method for promoting germination of polygonatum cyrtonema seeds. The method comprises the following steps: S1, processing river sand; S2, processing polygonatum cyrtonema fruits; S3, preparing a 200 mg / kg gibberellin solution, using the gibberellin solution to moisten the river sand in the S1 to a humidity of 14%-18%; S4, treating polygonatum sibiricum seeds; S5, conducting stratification of the polygonatum sibiricum seeds in the S4 in the river sand in the S3, conducting treatment at 28 DEG C-29 DEG C for 45 days and keeping the humidity of the river sand at 14%-18% during the treatment period to obtain germinated polygonatum sibiricum seeds; and S6, conducting a low-temperature treatment of the polygonatum cyrtonema seeds in the S5 and then sowing the seeds in the soil. Compared with polygonatum cyrtonema seeds in a natural state, the polygonatum cyrtonema seeds treated by the method havea germination rate increased to 92% or more and an emergence rate increased to 83% or more. Compared with the polygonatum cyrtonema seeds treated by a conventional germination technology, the polygonatum cyrtonema seeds treated by the method of the present invention are also obviously increased in the germination rate and emergence rate and greatly improved in breeding efficiency of polygonatum cyrtonema seedlings.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for promoting the germination of Polygonatum multiflora seeds. Background technique [0002] Polygonatum multiflora is a perennial herb of the genus Polygonatum in the family Liliaceae. The rhizomes are thick, rarely nearly cylindrical, and the stem height can reach 100 cm. The leaves are alternate, oval, ovate-lanceolate to oblong-lanceolate, Umbels, yellow-green perianth, black berries, flowering in May-June, fruiting in August-October. [0003] Polygonatum multiflora is mainly distributed in Sichuan, Chongqing, Guizhou, Hunan, Hubei, Henan, Jiangxi, Anhui, Jiangsu, Zhejiang, Fujian, Guangdong, and Guangxi in China. Born in forests, shrubs or shaded hillsides, Polygonatum multiflora is artificially planted in Nanchuan, Xiushan, Pengshui, Kaizhou, Shizhu, Tongliang and other places in Chongqing. [0004] The medicinal part of Polygonatum multiflora is the rh...

AI Technical Summary

Problems solved by technology

In the natural state, the dormancy phenomenon of Polygonatum multiflora seeds is serious. After the seeds are harvested and planted, they grow roots in the second year and only emerge in the third year. There are problems such as low seed germination rate, low emergence rate and late emergence time in production.
