A kind of large-scale cultivation method of dianthus polyphylla seedlings

Abstract

The invention discloses a large-scale cultivation method for paris polyphylla seedlings. The method includes the following steps that firstly, selected land is subjected to deep tillage and sun exposure, then base fertilizer is applied, furrow opening is conducted, and humus soil is scattered on the furrow face; afterwards, harvested fruits are peeled and soaked by warm water and gibberellin, and the soaked fruits are evenly mixed with sand for dark light storage; sowing can be performed after storage for 2-5 months, the temperature and humidity of the interior of an arched shed need to be reasonably controlled after sowing is completed, and reasonable topdressing is carried out. By means of the large-scale cultivation method, the emergence rate of the seedlings is effectively increased and can reach 85%; moreover, emergent seedlings are neat, the growth vigor of the seedlings is high, rooting is fast, and the survival rate of the seedlings can reach 96%. The method has the advantages of being easy to operate, low in cost, easy to popularize, and capable of effectively shortening the germination period of paris polyphylla seeds and simplifying the seedling raising technique of the paris polyphylla seeds. Benign development of the paris polyphylla planting industry is effectively promoted, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a method for large-scale cultivation of Rhizoma Dianchia seedlings. 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, there has been a sharp increase in the market demand for Dianzhong, and the annual consumption has far exceeded the growth of D...

Problems solved by technology

As for the planting of P. dianthus, the cultivation of seedlings is the key to planting P. dianthus. At present, the domestic cultivation of P. Finally, take the rhizome of Dianzhonglou, cut it at 3 to 4 cm in length with the terminal bud part according to the direction perpendicular to the main axis of the rhizome, dip the wound in plant ash and sow it on demand in the field, and use the rhizome to cut and plant, which will occupy a large amount of raw materials for production, resulting in The contradiction between cultivation seeds and medical raw materials is intensified. In addition, the cut rhizomes are easy to be infected with mold and rot due to the difficulty in controlling the moisture and temperature in the field. The loss rate of rhizome materials is as high as more than 50%. , the cost of planting is relatively high, and the use of seed germination to grow seedlings, due to the dormant characteristics of the seeds of Chonglou dianthus, if they are allowed to germinate naturally, it will take more than one year to emerge, and the emergence rate can only reach about 50% at most, and after emergence Poor growth and slow growth, completely unable to meet and adapt to the needs of large-scale planting and promotion of Dianzhonglou
