Method of domesticating Bletilla striata seedlings

Abstract

The invention discloses a method of domesticating Bletilla striata seedlings, which comprises the steps of A, constructing a greenhouse, to be specific, building a conjoined greenhouse on a land meeting the environmental condition requirements, and applying an integrated water-fertilizer management system; B, preparing a seedbed, to be specific, deeply scarifying the land to 20 cm or deeper; making beds according to the bed width of 1.0-1.2 m, bed height of 15-20 cm and bed ditch width of 30-40 cm; C, scattering seeds, to be specific, collecting tubers of directly-sowed seedlings of Bletilla striata, growing for 6 months or longer and in flattened state, from November to next January, scattering the tubers to the seedbed according to the density of 350-400 plants per m<2>; D, providing field management, to be specific, 1, supplying water, to be specific, maintaining relative water retention of the seedbed to 60-80%; 2, weeding, to be specific, removing weeds manually, which are removedupon presence; 3, applying fertilizer, to be specific, starting to perform topdressing when the seedlings grow new buds; 4, comprehensively preventing and treating disease and pest damage, to be specific, spraying the seedbed and pests with agents; E, lifting seedlings, to be specific, lifting the seedlings manually. The method herein is low in cost, short in seedling growth period, high in seedling yield, good in seedling robustness and high in post-transplanting survival rate.

Description

technical field [0001] The invention relates to the technical field of cultivating medicinal bletilla seedlings, in particular to a method for domesticating bletilla seedlings. Background technique [0002] Bletilla striata (Thunb.) Reichb.f. is a perennial plant of the genus Bletilla in the family Orchidaceae, and the dry tuber of Bletilla striata (Thunb.) Reichb.f. , Millennium Palm, etc. All calendar editions of "Chinese Pharmacopoeia" are included. "Chinese Pharmacopoeia" (2015 edition) claims that it tastes bitter, sweet, astringent, slightly cold in nature, and belongs to the lung, liver, and stomach meridian. Sores are swollen and toxic, and the skin is chapped. Baiji is a commonly used Miao medicine. The name of the Miao medicine is "bid nggoub" (approximately Chinese transliteration: "bi dog"). It is cold in nature, bitter in taste, and enters the heat meridian. Have astringent to stop bleeding, detumescence and granulation promoting, pain relieving and astringi...

Problems solved by technology

Therefore, the cost of traditional Baiji seedling breeding method is high, and the aseptic seedling breeding method of Baiji has a long seedling cycle, and the yield of Baiji seedlings is low, the seedlings are thin and weak, and the survival rate after transplanting is low
