Bletilla striata tissue culture seedling exercising and cultivation method

Abstract

The invention provides a bletilla striata tissue culture seedling exercising and cultivation method. The method comprises the steps that a matrix is prepared, seedling exercising is conducted in bottles, seedlings are taken out of the bottles, domestication and cultivation are conducted, and domestication management is conducted, wherein the domestication matrix is prepared by evenly mixing sandy soil or soil with sand, humus soil and sawdust. According to the bletilla striata tissue culture seedling transplantation method, every three cleaned tissue culture seedlings form a cluster, and the tissue culture seedlings are shallowly planted into a seedbed in a green onion arranging mode. By means of the cultivation method, the survival rate of the bletilla striata tissue culture seedlings transplanted to the field and the yield are increased, the transplanting survival rate of domesticated seedlings reaches over 95%, and the investment cost is lowered for a grower.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and in particular relates to a seedling hardening and cultivation method for tissue cultured seedlings of bletilla radix. Background technique [0002] Baiji is a perennial herbaceous plant belonging to the family Orchidaceae, also known as Baigen, Ground Screw, White Chicken Baby, Claw Seven, Purple Orchid, Knife Edge Medicine, Lianjicao, etc. The tubers are used for medicine, which can restrain bleeding, reduce swelling and promote granulation; treat diseases such as tuberculosis and hemoptysis, bronchiectasis hemoptysis, gastric ulcer, hematemesis, hematuria and hematochezia. External use to treat traumatic bleeding, burns, chapped hands and feet embolism. It has huge commercial application value in biomedicine, health food, textile printing and dyeing, special coatings and daily chemical industry. With the development and utilization of baiji food and the demand...

Problems solved by technology

Most of the current conventional methods are based on division, that is, the tubers are cut into small pieces for planting, and the reproduction coefficient is low, which can no longer meet the needs of the market.

People have started artificial propagation, and many places have adopted the method of tissue culture propagation to obtain a large number of seedlings quickly; because tissue culture propagation is carried out in an artificial environment, its self-supporting ability is very poor, especially the absorption function of its roots, stems, etc. The dredging and transportation function of the leaves and the photosynthetic function of the leaves cannot adapt to the external environment, and they cannot fully perform their functions, which leads to a very low survival rate of transplanting. Therefore, domestication is required to successfully transplant to improve its survival. Rate
