Problems solved by technology

During the production, cut rhizomes and seeds are mainly used for seedling breeding of Chonglou Dianchi. One rhizome for cutting seedlings can only produce 6-7 seedlings, while one rhizome for seed breeding can produce 100-200 seedlings per year. Its seedling raising efficiency is much higher than that of rhizome seedling raising, but the seeds of Chonglou Dianchi have after-ripening of the embryo. Under natural circumstances, it takes two winters and one summer to germinate. The seedling rate of 15 months is only 46.2%. During the dormancy period, the vitality is lost, which limits the seedling growth and restricts the development of the planting industry of Dianzhonglou

Abstract

The invention discloses a Paris polyphylla dicing breeding method. The method comprises the steps of (1) land selection, (2) seedling processing, (3) planting and (4) field management. In the step (1), a loessland plot with loose soil and good breathability is selected; humus is spread on the plot to a thickness of 3-5cm; deep plowing is carried out to a depth of 22-25cm, and the soil layer is fully mixed and crushed; before deep plowing, preventive sterilizing and pest killing are carried out upon the entire plot, and soil turning and deep plowing is carried out the next day; the process is repeated once; a seedbed specification is that the width is 1.2m, a soil layer is flat, and soil thickness is uniform; the land is neatly arranged before usage. In the step (4), a relatively high humidity is maintained, and waterlogging is prevented; during continuous sunny days, full spray-irrigation should be carried out every 10 days; when Paris polyphylla emerges, a sunshade shed is built for preventing direct sun exposure of the seedlings, wherein a sunshade net density is 75-85%. With the method, the difficulty brought by seedling raising with seeds is solved, and large-scale propagation can be realized.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine planting, in particular to a method for cutting and propagating Pachyphytum diangi. Background technique [0002] Dianzhonglou, also known as unicorn lotus, is a perennial herb of Trilliumaceae, and it is an authentic medicinal material in Southwest China. All previous editions of the "Chinese Pharmacopoeia" have recorded that the rhizome is used as medicine, which has anti-tumor, hemostasis, cough and asthma, antibacterial, antiviral, analgesic and immune regulation effects. The medicinal materials of Dianzhonglou are mainly collected in the wild. In the 1980s, some people began to study the wild species. However, due to its low reproduction rate, long growth cycle, and long investment return cycle, most of them are carried out by investors in industrial transformation. Planting, over the years, artificial planting has developed slowly. [0003] For a long time, the artific...
