Embodiment 1

[0022] The mature Bletilla striata capsules are dried in the sun. After drying, the Bletilla striata capsules will naturally split, and the seeds are sieved out with a 120-mesh sampling sieve for later use.

[0023] Preparation of seed germination medium solution, adding NAA0.5mg, gac 0.5g, concentration of 15% by weight potato juice 150g, sucrose 20g in every liter of KC (KnudsonC) medium, adjusting the pH value to 5.8-6.0, filling Put 200 ml of medium solution in a 500 ml tissue culture bottle, close the lid and sterilize in a high-pressure sterilizer at 121°C for 26 minutes.

[0024] Put 20 grams of Bletilla striata seeds in each bottle of nutrient solution and soak for 36 hours, rinse with sterilized water three times, then use a clean towel to pack one bottle per bottle, and cultivate it in a plant incubator at 26°C for 15-20 days. The green seed buds that germinate are about 0.4mm wide.

[0025] Begin to grow seedlings around the beginning of spring every year. The seed...

Abstract

The invention belongs to the technical field of seed reproduction, in particular to a Bletilla striata seed direct seeding natural rapid reproduction seedling method.The method comprises the following steps that 1, ripe Bletilla striata capsules are sieved by a 120 mesh sample sieve for use after being dried in the sun; 2, a seed germination culture medium solution is prepared, 0.5-10 mg of NAA, 0.3-0.8 g of activated carbon, 100-150 g of potato juice with the concentration of 10%-15% by weight and 20-30 g of sugar are added to each liter of KC culture medium, and the pH value is adjusted to be 5.8-6.0; 3, 20 g of Bletilla striata seeds are placed into each bottle of nutrient solution to be soaked for 36-38 hours, and then green seed buds emerging by 0.2-0.5 mm are obtained by cultivation; 4, seedling is performed, the seedlings are moved out of a greenhouse after 3 or more leaves grow on the seedlings and are directly cultivated in a pine forest.

Description

technical field [0001] The invention belongs to the technical field of seed propagation, in particular to a method for direct direct natural rapid propagation of bletilla striata seeds. Background technique [0002] Bletilla striata (scientific name: Bletilla striata), also known as Lianjicao, Gangen, Baigi, Ruolan, Zhulan, Zilan, Zihui, Baili, is a perennial herb of the genus Bletilla striata in the family Orchidaceae. It is used as a medicine with dry tubers. Cold, bitter, sweet, and astringent. It has the effects of nourishing the lungs, stopping bleeding, dispelling wind and dehumidification, clearing the orifice and relieving pain, reducing swelling and discharging pus, promoting muscle growth, and astringing sores. Blood, ulcer bleeding embolism. It is one of the precious traditional Chinese medicinal materials in our country, and the market demand is very large. In recent years, artificial over-harvesting and destruction of natural habitats have sharply reduced wild...
