Seed treatment method to accelerate the germination of Polygonatum seeds

Abstract

The invention relates to a seed treatment method for accelerating the germination of Polygonatum chinensis seeds. 2. Finally, go through normal temperature hormone strong magnetic field to induce germination, and then carry out seedling raising or planting. After 50 days of sowing, the germination rate of Polygonatum chinensis seeds treated by the present invention can reach more than 90%, and after 60 days of sowing, the germination rate can reach 90%. About 93%, the invention can effectively reduce the dormancy time stored at room temperature greatly, greatly improve the germination rate, can significantly shorten the growth cycle of Polygonatum chinensis, reduce the amount of seeds when planting Polygonatum chinensis, reduce the planting cost of Polygonatum chinensis, and is suitable for large-scale Polygonatum chinensis seeds. Promotion and use of Ueda.

Description

technical field [0001] The invention relates to the technical field of Polygonatum chinensis planting, in particular to a seed treatment method that can quickly break Polygonatum chinensis seed dormancy and accelerate Polygonatum chinensis seed germination when using Polygonatum chinensis seeds to plant and breed Polygonatum chinensis. Background technique [0002] Polygonatum ( Polygonatirhizoma ) is a perennial herb of the genus Asparagaceae. According to the "Flora of China", there are about 60 species of Polygonatum in the world, which are widely distributed in the northern temperate zone, mainly from the Himalayas to Japan. There are 39 species in my country. Among them, the tubers included in the "Chinese Pharmacopoeia 2020 Edition" can be There are three kinds of Polygonatum for medicine: Polugonatumkingianum Coll.et Hemsl, Polygonatumwibiricum Red. and Polygonatumcyrtonema Hua. [0003] Huang Jing has a long history of medicinal use in my country. It was first recor...

Problems solved by technology

[0006] At present, for breaking the dormancy of Polygonatum seeds, there are already warm water immersion, layering treatment, hormone and chemical substance treatment, etc. However, no matter which treatment method, Polygonatum seeds must go through the process of germination at low temperature in sand storage for more than 100 days after harvesting. The germination rate of Polygonatum seeds treated with sand storage and breaking dormancy can only reach 85% in about 60 days after sowing, and the germination rate of Polygonatum seeds that have not been subjected to the low-temperature germination process of sand storage is only 30% after about 80 days of germination. ~40%

However, the low-temperature germination of Polygonatum seeds in sand storage is cumbersome, takes up a large area, has a long cycle, and has high requirements for temperature and humidity. Therefore, due to the dormancy characteristics and low germination rate of Polygonatum seeds, although the seed cost of seed breeding is relatively The cost of tubers is low, but Polygonatum seed breeding is still not accepted by Polygonatum growers or planting enterprises. If a way to quickly break seed dormancy can be found, it is more suitable for large-scale Polygonatum seedlings or planting
