Method for geminating Rhizoma Paridis Yunnanensis

Abstract

The invention belongs to the technical field of valuable and rare Chinese herbal medicine cultivation and specifically relates to a method for geminating Rhizoma Paridis Yunnanensis. The operation method comprises following steps: selecting mature Rhizoma Paridis Yunnanensis seeds which are harvested in the current year, are bright and plump and red after shelling; performing natural drying in shade until the skin moisture is from 47% to 53%; placing the seeds in a container with constant temperature of 7 DEG C, taking out the seeds after 6 to 8 days and soaking the seeds in alkaline water with pH 7.4 to pH 9 for 1 to 2 hours; then spreading the seeds on greenhouse cultivation base, covering the cultivation base with substrate soil, wherein the humidity of the cultivation base is 25% to 36%, the temperature inside the greenhouse is 24 DEG C + / -1, and the humidity is controlled between 42% to 45%. The method is simple; the germination time of seeds is uniform; the germination rate of Rhizoma Paridis Yunnanensis seeds can be stably increased; the germination rate reaches about 76%; the Rhizoma Paridis Yunnanensis seedlings can be transplanted in the next year so that the cultivation cost of Rhizoma Paridis Yunnanensis is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of cultivation of famous and precious Chinese herbal medicines, and in particular relates to a method for germination of Pachyphytum dianthus. Background technique [0002] Dianchonglou Paris polyphylla var. yunnanensis (Franch.) Hand.- Mazz. , alias unicorn lotus, is a perennial herb, suitable for growing in areas with an altitude of 1600-3100m, with an annual average temperature of 12-13°C and a frost-free period of more than 270 days. The annual rainfall is 850-1200mm, the rainfall is concentrated between June and September, the air humidity is above 75%, and the night tide of the soil can meet the needs of the growth and development of Dianzhonglou for soil water content. The seeds of Chonglou Dianchi have obvious post-ripening effect, and the embryos need to be dormant and post-ripening before they can germinate. Under natural conditions, it takes two winters to emerge from the soil and the seedlings e...

Problems solved by technology

[0003] In order to solve the problem of the lack of sources of P. dianthus, people have long begun to simulate its growth environment and test planting in many places in Yunnan, but it is difficult to solve the problem of low emergence rate.

After years of hard work, technical personnel in Yunnan have explored a set of more standardized planting methods for Prunus diangi in recent years, which has greatly improved the survival rate of Ponytail dianthus seedlings, and the emergence rate of seeds has also increased to a certain extent, but the emergence rate of seeds is not high. Stable, the highest can only reach about 56%, and if the operation is not in place, the emergence rate will be greatly reduced, which will greatly increase the production cost of building seedlings
