Embodiment 1

[0024] A method for sexually propagating and raising seedlings of bletilla striata, comprising the following steps:

[0025] (1) Select the soil with a sand content rate of 30% as the base, and sprinkle quicklime on the surface of the base, sprinkle 1kg per square meter, spray water accounting for 11% of the weight of quicklime, cover it with rice husks to a thickness of 1cm, plow to a depth of 10cm, and harrow flat;

[0026] (2) Dig a pit on the base treated in step (1). The pit is 10 cm deep. The pit is a circular pit with a diameter of 5 cm. Fill the bottom of the pit with a nutrient base of 5 cm, cover it with sawdust for 3 cm, and then cover it with rice husk for 2 cm. , and adjust the moisture content of sawdust and rice husk to be 30%, then use rice husk to cover the pit wall with a thickness of 1cm, and then use sawdust to cover a thickness of 1cm, sprinkle water to adjust the moisture content inside the pit to 35%, adjust the temperature to 30°C and place it for 5 sk...

Abstract

The invention relates to the technical field of sexual propagation seedling culture of Bletilla striata, in particular to a sexual propagation seedling culture method for the Bletilla striata. A process comprises steps of base selection and treatment, pit digging treatment, pit depth and pit inside structure layout, Bletilla striata pod treatment and arrangement of Bletilla striata pods into pits. According to limit of the process steps and process parameters, the Bletilla striata can sprout and emerge rapidly on a base, weed infestation of the Bletilla striata seedling culture base can be prevented, the labor intensity for the Bletilla striata seedling culture base is reduced, influence on Bletilla striata seedlings in a weeding process is avoided, and the survival rate of the Bletilla striata seedlings is increased; nutrition supply of the Bletilla striata pods in germination, sprouting and emerging stages is guaranteed, sufficient oxygen supply can be realized, fermentation heating of organic matters such as rice husks, sawdust and the like in the base is realized, energy consumption in the Bletilla striata growth process is guaranteed, the budding rate of the Bletilla striata is reduced, the emergence cycle of the Bletilla striata is shortened, and the Bletilla striata seedling culture cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bletilla striata sexual reproduction and seedling cultivation, in particular to a method for sexual reproduction and seedling cultivation of bletilla striata. Background technique [0002] Bletilla striata is a perennial herbaceous plant of the genus Bletilla striata in the family Orchidaceae. It is a commonly used medicinal material, and its tubers are used as medicine. For a long time, the bletilla striata market has mainly relied on wild resources, which have been severely exploited, coupled with the destruction of the ecological environment, and wild resources are becoming increasingly depleted. The natural germination rate of Bletilla striata seeds is extremely low, and reproduction is difficult. Artificial breeding is a powerful measure to satisfy the market of Bletilla striata. Most of the current conventional methods are based on division, that is, the tubers are cut into small pieces for planting...
