Regulation and control method for enabling flowering phases of Gastrodia elata Bl. f. glauca S. Chow and Gastrodia elata Bl. f. elata to meet

Abstract

The invention discloses a regulation and control method for enabling flowering phases of Gastrodia elata Bl. f. glauca S. Chow and Gastrodia elata Bl. f. elata to meet. The regulation and control method comprises the steps of seed selection, winter storage, cultivation and flowering phase meeting. The method has the advantages that under natural conditions, firstly, selected Gastrodia elata Bl. f.glauca S. Chow seeds subjected to winter storage treatment is cultured; when Gastrodia elata Bl. f. glauca S. Chow arrow buds expand and germinate, Gastrodia elata Bl. f. elata seeds subjected to winter storage treatment are transferred to a Gastrodia elata Bl. f. glauca S. Chow cultivation place for same-condition cultivation; when certain cultivation requirements are met, Gastrodia elata Bl. f.glauca S. Chow and Gastrodia elata Bl. f. elata which are cultivated under the same condition are transferred to natural conditions, flowering phase encounter of the Gastrodia elata Bl. f. glauca S.Chow and the Gastrodia elata Bl. f. elata under the natural conditions is achieved, the average flowering phase encounter rate is 75%-100%, and compared with a traditional method, the regulation costis respectively reduced by 4.15 times, the cost is low, time and labor are saves, management is easy and popularization is easy; Gastrodia seeds which are full in bud scale, free of pest and disease damage, free of damage and intact in individual are selected in a seed selection stage, so that the flowering rate of robust bolting and inflorescence is increased; and the low-temperature winter storage treatment of the Gastrodia seeds is beneficial to control of germination and growth time.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a regulation method for making the flowering stages of Gastrodia elata and Gastrodia elata meet. Background technique [0002] Gastrodia elata Bl.f.g laucca S.Chow×G.elataBl.f.ela ta is a new hybrid variety experimentally studied by Yichang Forestry School in Hubei Province from 1995 to 1998. Advantage. Gastrodia elata is mostly distributed in broad-leaved forests at an altitude of 1600-1800m, and the flowering period is generally from late June to early July; red Gastrodia elata is mostly distributed in broad-leaved forests at an altitude of 1200-1400m, and the flowering period is generally from late May to June early. Under natural conditions, the flowering period of Gastrodia elata and Gastrodia elata differs by 20 to 30 days. Therefore, to cultivate a sexual hybrid Gastrodia elata species of Gastrodia elata × Gastrodia elata, it is usually necessary to control the temperatu...

Problems solved by technology

However, in actual production practice, the above-mentioned method of making Gastrodia elata and Gastrodia elata meet at the flowering stage is costly, labor-intensive, time-consuming, and management is difficult, which restricts its popularization and application.
