Abstract

The invention discloses a method for promoting germination of curcuma alismatifolia seeds. The method adopts hot water and hormone to treat the curcuma alismatifolia seeds together, effectively breaksthe dormant state of the curcuma alismatifolia seeds, obviously shortens the seed germination time, can realize germination of the curcuma alismatifolia seeds within one month, has high seed germination uniformity, ensures that the germination rate of the curcuma alismatifolia seeds reaches 64.3% within 60 days, and is suitable for large-batch seedling; meanwhile, required materials are simple, the cost is low, the operation is easy, and the seeds only need to be soaked by using the hot water with specified temperature and preparing a hormone solution with specific concentration according tosteps; and treated seedlings grow normally and have vigorous vitality, current-year sowing and current-year flowering of the curcuma alismatifolia seeds can be realized, and the breeding period is shortened, so that the breeding process is accelerated, and the method is suitable for application and popularization in breeding practice.

Description

technical field [0001] The invention relates to the technical field of ornamental plant cultivation and cultivation, in particular to a method for promoting germination of ginger lotus seeds. Background technique [0002] Ginger lotus (Curcuma alismatifolia) belongs to the genus Curcuma longa of the Zingiberaceae family. It is a perennial bulbous flower. Because of its beautiful flower shape, long-lasting flowering period, and gorgeous flower colors, it can be widely used in street greening, park landscaping and flower sea design. middle. [0003] The natural flowering period of ginger lotus is from June to October, and the suitable temperature for growth is 26-30°C, which is very suitable for planting and promotion in subtropical regions such as Guangdong. In addition, the vase life of ginger lotus can reach 15 days. It is a high-grade cut flower variety with high economic benefits and broad prospects for development and utilization. [0004] At present, most of the mains...
