Paris polyphylla var. yunnanensis scale seedling culturing method

Abstract

The invention relates to a Paris polyphylla var. yunnanensis scale seedling culturing method. The method comprises the following steps of: selecting Paris polyphylla var. yunnanensis plants more than 10 years old and reserving seeds for planting; collecting mature seeds; washing the collected seeds to remove episperm; spreading and drying the seeds in a shade and ventilating place within 12 hours, wherein a temperature is maintained and an accumulation thickness is less than or equal to 6 cm; spreading the seeds uniformly and drying; filling the seeds into a ventilating container; storing thecontainer in a shade environment with a suitable temperature, wherein the storage time is no more than 2 months; clearing impurities and residues in a seedling culturing field; fertilizing decayed farm manure and calcium superphosphate; plowing and raking soil; forming a furrow; spreading humus soil on the furrow surface; flatting the furrow surface; sowing in early June next year; taking the stored seeds, and after sterilizing, broadcasting the seeds uniformly according to the thickness of sowing; earthing after broadcasting; covering mantle on the furrow surface; irrigating sufficiently andperforming seedling management. A method for drying the seeds of the Paris polyphylla var. yunnanensis in shade in an environment without direct sunlight is adopted, the dormancy of the seeds of the Paris polyphylla var. yunnanensis is broken, and the scale production of Paris polyphylla var. yunnanensis seedlings is realized, so that germchit guarantee is provided for large-area popularization and cultivation of the Paris polyphylla var. yunnanensis. The method has the characteristics of simple and easily-learned operation, high survival rate of germchit, low production cost, healthy and strong germchit, stable and reliable technology, high repeatability, and capacity of effectively solving the problem of scale seedling cultivation of the Paris polyphylla var. yunnanensis.

Description

technology field; [0001] The invention relates to a method for large-scale seedling cultivation of Chonglou dianthus, belonging to the technical fields of traditional Chinese medicinal material cultivation and agricultural seedling cultivation. technical background: [0002] Dianzhonglou (Paris polyphylla Smith var.Yunnanensis (Franch) Hand.-Mazz) is a traditional Chinese medicine commonly used in my country. One of the base plants of Zhonglou is also the raw material of many famous Chinese patent medicines in my country. Since 2000, the price of Dianzhong building has risen rapidly, and the current price is 200 yuan / kg, and the annual demand for Dianzhong building is about 1 million kilograms. [0003] At present, the Dianzhong building on the market is dominated by wild resources. Due to the shortage of goods and high prices, over-harvesting has caused serious damage to wild resources. Now the wild resources of Dianzhonglou have fallen into a vicious circle of "the more y...

Problems solved by technology

Although the above-mentioned technology can improve the germination rate of seeds, there are still problems such as complicated operation, high management cost, easy mildew or rot of seeds during treatment, and weak seedlings, and the seeds treated by accelerating germination have already grown embryos. If you are not careful, you will break the radicle and affect the survival of the seeds. These methods are currently mainly used in laboratory research or small-scale experiments, and are not suitable for the production needs of large-scale and large-scale Dianzhonglou seedlings.
