Problems solved by technology

At present, the substrate used for the domestication of Bletilla striata seedlings is generally a mixture of perlite, peat soil, peat, river sand, etc. Since the growth of Bletilla striata requires a lot of water, the moisture content in the substrate should be kept at 60 % to 70%, therefore, the amount of watering each time is large, and the water is easy to accumulate at the bottom of the substrate, causing the roots of Bletilla striata to suffer from waterlogging, thereby affecting the normal growth of Bletilla striata

Abstract

The invention discloses a domestication cultivation method of bletilla striata tissue culture seedlings. The domestication cultivation method comprises the following steps: A, preparing a substrate, wherein the substrate comprises mixtures of pine nut shells, humus soil and sheep manure and mixtures of sawdust, chicken manure, bean cakes and sesame oil residues; B, digging a culture pool in a greenhouse, C, successively spreading the mixtures of the pine nut shells, humus soil and sheep manure and the mixtures of the sawdust, chicken manure, bean cakes and sesame oil residues in the culture pool; D, selecting the bletilla striata tissue culture seedlings, and then cleaning, carrying out disinfection and drying; E, planting the tissue culture seedlings obtained in the step D on the substrate in the culture pool, wherein the row spacing is 2 cm to 4 cm, and the plant spacing is 1 cm to 2 cm; and F, managing: controlling the temperature in the greenhouse to be within 22 to 25 DEG C, the humidity to be within 60% to 70%, the illumination intensity to be within 2500 LX to 3000 LX, and the illumination time for 10 h to 13 h daily; regularly watering; and transplanting in fields after 3 months. The bletilla striata tissue culture seedlings are domesticated by using the method, so that good growth of the tissue culture seedlings can be ensured, the ratio for meeting requirements of field transplantation is greatly increased, and the qualified rate of the tissue culture seedlings is improved.

Description

technical field [0001] The invention relates to the technical field of bletilla striata planting, in particular to a method for domesticating and cultivating bletilla striata tissue culture seedlings. Background technique [0002] Bletilla striata is a species of Bletilla striata in the family Orchidaceae. Perennial herb, 20-50 cm high, with 4-5 leaves, the bases are nested into stems, and the scapes are drawn out from the center. Racemes with several flowers; flowers purple or light red, about 5 cm in diameter, composed of 3 sepals, 2 petals and 1 specialized lip; lip 3-lobed with longitudinal pleats; stamens and The styles are conjoined to form a zygote. There is an anther at the top of the gynocolum, and a stigma recess on the upper front. There are thick rhizomes underground, like a chicken head, rich in viscosity, containing white and gum, that is, white and mannan, which can be used for medicine. paste. [0003] The artificial cultivation of Bletilla striata genera...
