Efficient polyphylla seed seedling raising method

Abstract

The invention particularly relates to an efficient polyphylla seed seedling raising method. The method comprises the steps that in September and October, after fruits crack, and seed coats become darkred, polyphylla seeds are harvested; the seeds are soaked in clear water and then mixed with sand to rub off pulp, polyphylla seeds which are plump, mature and free of diseases, pests, mildew and damage are selected as seeds, soaked in a carbendazim solution and dried; the seeds and sand are mixed, packed in cloth bags, refrigerated and cultured repeatedly, and then sown; the treated seeds are sown in seedling raising trays, then covered with a layer of seedling media, then covered with straw and watered thoroughly. Accordingly, the seedling emergence cycle is effectively shortened, the seedling emergence rate is improved, the germination time is only about 120 days, the highest germination rate can reach 80%, and the seedling emergence is neat.

Description

technical field [0001] The invention specifically relates to a method for cultivating seedlings of high-efficiency pachyphylla seeds, which belongs to the technical field of traditional Chinese medicine cultivation. Background technique [0002] Chonglou is a traditional ethnic medicine, which was first recorded in "Shen Nong's Materia Medica" under the name of "Flea Xiu". The 2005 edition of "Chinese Pharmacopoeia" Part I is recorded as the dry rhizome of Paris polyphylla Smith Var.chinensis (Franch.) Hara and JP.polyphylla Smith var.yunnanensis (Franch.) Hand. Mazz of Liliaceae . Pachyphysis plants are mainly distributed in the tropical to temperate regions of Eurasia. According to data records, the two provinces of Sichuan and Yunnan, with the southern section of the Hengduan Mountains as the core area, are the geographical distribution centers and genetic diversity centers of Pachyphylla in Eurasia. The southern section of the Hengduan Mountains is located on the sout...

Problems solved by technology

There are few resources of chrysanthemum, and the propagation period of subterranean stem cutting is long, and the reproduction coefficient is low; it takes 1 to 2 winters for conventional seed sowing to grow seedlings, and the emergence cycle is long, irregular, and the emergence rate is low. The yield of Chonglou seeds is very low, coupled with the difficulty of traditional seed sowing and raising seedlings, this is the main reason why Chonglou seedlings are always scarce
