Magnolia biloba seed treatment method

Abstract

The invention provides a Magnolia biloba seed treatment method. The method can break the dormancy of Magnolia biloba seeds to make the Magnolia biloba seed reach an instant germination effect. The method comprises the following steps: 1, acquiring the seeds, placing the acquired fresh seeds on sand paper, kneading by hands to rub the seeds with the sand paper in order to shed the wax of testae of the seeds, rinsing the seeds by clear water after the shedding of the wax of the testae of the seeds, and screening to remove shriveled seeds; 2, placing the seeds obtained in step 1 in a watch glass, and carrying out poikilothermic changing treatment of the seeds three times, wherein the poikilothermic treatment comprises the procedures of treating at 25-27DEG C for 12h and then treating at 4-5DEG C for 12h, sufficient illumination is applied to the seeds at the last one hour of each time of the higher temperature treatment, and the illumination intensity is 2500-2800lx; and 3, immersing the seeds obtained in step 2 in a nutrient solution I for 4-5h, immersing the seeds in a nutrient solution II for 5-6h, taking out the seeds, and airing to obtain dry seeds which can be instantly sowed.

Description

technical field [0001] The invention relates to a cultivation method of Magnolia officinalis, in particular to a method for treating the seeds of Magnolia officinalis. Background technique [0002] Magnolia biloba (Magnolia biloba) is a deciduous tree of the Magnoliaceae Magnolia genus, native to Sichuan, Hubei, Hunan, Guangxi, Zhejiang, Jiangxi, Fujian, Jiangsu and other places. It integrates medicinal, material and ornamental functions. It is a unique economic tree species in my country, and it is also a national second-class key protected plant. It has a very broad prospect of utilization. Over the years, the demand for Magnolia officinale has been increasing, and the wild resources have been continuously reduced, while the seeds of Magnolia officinalis are post-ripening and hard, have deep dormancy characteristics, and their natural reproduction rate is low. [0003] Using plant growth regulators and temperature control to treat seeds, improve seed vigor, enhance seedli...

AI Technical Summary

Problems solved by technology

Over the years, due to the increasing demand of Magnolia officinalis and the decrease of wild resources, the seeds of Magnolia officinalis have post-ripening and hard properties, deep dormancy characteristics, and low natural reproduction rate

[0003] Using plant growth regulators and temperature control to treat seeds, improve seed vigor, enhance seedling germination rate in adversity, control plant seedling growth and promote weak, strong and strong seedling treatment technology has been well received in Magnolia officinalis Applications, such as (Hu Jiangqin et al., Research on the dormancy and germination characteristics of Magnolia officinale, "Journal of Hangzhou Normal University", Volume 10, No. 4, July 2011), (Chen Xinyun, Research on high-yield cultivation techniques of Magnolia officinale in northern Fujian, "Strait Pharmacy", Volume 22, No. 5, 2010), etc., but the above method is only a preliminary experimental study on the seed germination of Magnolia officinalis, and there is no systematic and effective technology to break dormancy, and the break dormancy time is long
