Hole-ground film direct sowing culture method for paris polyphylla

Abstract

The invention discloses a hole-ground film direct sowing culture method for paris polyphylla. The method comprises the following steps: selecting seeds which are full in buds and are fully ripened, peeling, sterilizing, directly seeding the seeds on a black film which is pretreated and sterilized and is provided with direct sowing holes, covering the film on a nursery garden, retaining that the moisture content of soil is between 50 and 60 percent after seeding, completely weeding, and preventing and controlling plant diseases and insect pests of paris polyphylla after seedling emergence by adopting a physical trapping method. Compared with the traditional culture method, the method disclosed by the invention has the advantages that the seedling emergence rate of the seeds is effectively improved, the manual cost generated during seed sprouting and transplanting is saved, the resources are greatly saved, any chemical pesticide residue is avoided, the quality and drug effect of paris polyphylla can be completely remained, and the planting method is simple in technical program and easy to perform, is a direct seed sowing technology with the advantages of simplicity, effectiveness, low cost, high germination rate, good growth vigor and high disease-resistant immunity, is prominent in effect and is easy for large-area cultivation promotion.

Description

technical field [0001] The invention belongs to the technical field of cultivation of traditional Chinese medicinal materials, and in particular relates to a film-punched and direct-seeded cultivation method of Dianchrysmus chinensis. Background technique [0002] Dianzhong is a perennial herbaceous plant belonging to the family Liliaceae. In my country, it is mainly distributed in Yunnan, Guangxi, Guizhou, Sichuan and other places. Dianzhonglou is used as medicine with rhizomes. It is slightly cold in nature, bitter in taste, and slightly poisonous. It is a traditional Chinese medicine variety in China. It is one of the main raw materials of Yunnan Baiyao and antiviral granules for external use to treat iron attacks, insect bites, lymphatic tuberculosis, and sores. Research shows that it also has the effects of detoxification, beauty and health, and unique antiviral effects. In recent years, the demand for Dianzhong in the market has also increased sharply. The annual cons...

AI Technical Summary

Problems solved by technology

However, the artificial cultivation of Chonglou is generally obtained by planting rhizomes or seedlings. Due to the small number of terminal buds of the rhizomes and the limited number of provenances, the supply of medicinal materials will be seriously affected, and the contradiction between cultivated species and medical raw materials will intensify. Therefore, at present, the seedlings of Chonglou Dianchi are generally obtained through seed breeding. However, in the process of raising seedlings of Chonglou Dianchi, because the seeds of Chonglou Dianzi have a long dormant period, it is necessary to use inducible auxin to accelerate the germination of the seeds. Transplanting after seedling raising, in the above-mentioned process of adopting seed seedling raising, cultivators often encounter slow seedling emergence of seeds, generally need two years, low seedling emergence rate, and the emergence rate can only reach about 70%, irregular seedling emergence, transplanting After planting, the growth is slow, prone to diseases and insect pests, many and cumbersome planting procedures, etc. Although many scientific researchers are constantly researching and seeking breakthroughs, according to actual practice and combined with published related papers, there are still labor costs, equipment, etc. The cost of supplies, the high cost of reagents, and the serious waste of seeds cannot achieve the expected planting effect at all.
