Tuber breeding method for Bletilla striata

Abstract

The invention discloses a tuber breeding method for Bletilla striata. The method comprises the steps of carrying out field selection and preparation, carrying out Bletilla striata planting, carrying out field management, carrying out water and fertilizer management and carrying out harvesting and processing. According to the method, adult seedlings on the market are planted firstly, and then, tubers are applied to breeding. The planting breeding of Bletilla striata is extremely difficult, and the adult seedlings of Bletilla striata are mostly cultured from Bletilla striata seeds in special culture media, so that the adult seedlings of Bletilla striata are relatively expensive. According to the method, the adult seedling breeding of Bletilla striata is changed into tuber breeding, selected tubers are current-growth tubers with tender shoots, and the breeding capability of Bletilla striata is enhanced due to the selection; three tubers are placed in each pit, so that the rate of empty seeds is lowered, land resources are effectively utilized, and the planting cost of Bletilla striata is reduced; and reasonable field selection and preparation, field management and soil fertilizer management also facilitate the growth and breeding of Bletilla striata.

Description

Technical field

[0001] The invention relates to the technical field of artificial planting of medicinal plants, in particular to a method for propagation of white tubers. Background technique

[0002] Bletillastriata (Bletillastriata) is a perennial herbaceous plant belonging to the orchid family Bletillastriata, a second-level national endangered plant, also known as Bletilla striata and purple orchid. It is mainly distributed in Guizhou, Hubei, southern Shaanxi and other regions south of my country's Qinling Mountains. It usually grows in evergreen broad-leaved forests at an altitude of 100 to 3,200 meters, in grasses on the roadside or in cracks in rocks. Its rhizome is white and several connected, hence the name Baiji or Baigen.

[0003] Baiji's nature and flavor return to meridian: cold in nature, bitter, sweet, astringent, non-toxic; return to lung, stomach, liver meridian. Baiji's functions and indications: astringent, hemostasis, swelling and muscle growth. Indications ...

Carry out the second weeding in June, the third weeding from August to September, and the fourth weeding from December to January of the following year. Weeding should be done shallowly to avoid root damag...
