AI Technical Summary

Problems solved by technology

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, for many years, the development of artificial planting has been slow, and a large part of the reason for the slow development of artificial planting is that the seeds of Dianzhonglou have a long breeding time and low germination rate. In the existing technology, the seed breeding cycle of Dianzhonglou is as long as Three years, and the breeding requirements are high, resulting in high breeding costs

Abstract

The invention discloses a breeding method for an improved Paris polyphylla var. yunnanensis variety. The breeding method comprises the following steps: seed-bed selection: selecting an under-forest vacant land with rich organic matters and good shading; seed selection: selecting full and mature Paris polyphylla var. Yunnanensis seeds which are free of diseases, pests, mildew and damage and has uniform size and a thousand seed weight of 50g to 60g; seed treatment: mixing the Paris polyphylla var. Yunnanensis seeds with clean fine sand in a ratio of 2: 1, carrying out rubbing to remove testa, carrying out washing, and soaking the Paris polyphylla var. Yunnanensis seeds to accelerate germination; sowing; topdressing; disease and pest prevention treatment: directed at diseases and pests like root rot, leaf blight, cutworm and grubs, carrying out prevention treatment; and harvesting. According to the invention, through improvement to Paris polyphylla var. Yunnanensis in the processes of seed selection, seed treatment, sowing and topdressing, the germination rate of the improved Paris polyphylla var. Yunnanensis variety is improved, and the breeding cycle of the Paris polyphylla var. Yunnanensis seeds is shortened.

Description

technical field [0001] The invention belongs to the technical field of polyphylla diarrhea breeding, and in particular relates to a method for breeding fine varieties of polyphylla dioica. 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, for many years, the development of artificial planting has been slow, and a large part of t...
