A Detailed Guide to Selecting and Raising Glehnia littoralis Seeds
On hillsides and in wasteland in rural areas, all kinds of plants are often seen, and many plants have certain medicinal effects and are used in medicine. For example, the root of Glehnia littoralis has many effects: it can nourish yin and clear the lungs, resolve phlegm and relieve cough. It is mainly used for dry cough due to lung dryness, damage to body fluids from febrile disease, thirst, and other symptoms. If you plan to grow Glehnia littoralis, how should its seeds be selected? What seedling-raising methods are there? Friends who want to know should read on quickly!
1. How are Glehnia littoralis seeds selected?
For Glehnia littoralis seeds, you should choose fresh seeds produced in the current year, with fuller grains, a glossy surface, and a purple-blue color, and with purity higher than 95% and moisture content below 9% for sowing, which can better ensure the germination rate.
2. Seedling-raising methods for Glehnia littoralis seeds
1. Soil selection and land preparation
Glehnia littoralis likes to grow in sandy soil or sandy loam soil, while pure yellow or red rocky soil is not suitable. The land must be deep-plowed more than 70 cm, and the clods fully broken up, with grass roots and stone debris picked out clean. Apply 1500-2000 kg of barnyard manure per mu and mix it fully with the soil as base fertilizer. Therefore, Glehnia littoralis is a fertilizer-tolerant crop, and the more fertilizer the better. The fertilizer is generally barnyard manure, green manure, heated kang soil, and plant ash and other fertilizers rich in phosphorus and potassium; nitrogen fertilizer should not be excessive.
2. Intertillage and weeding
For weeds in Glehnia littoralis fields, generally a hoe is not used for weeding; instead, they are pulled by hand, so as not to damage the seedlings with the hoe and affect root growth. Pull them whenever there are weeds, at least 5 times each year.
3. Winter and spring management
For winter-sown Glehnia littoralis, after it snows in winter, move snow into the field to help preserve soil moisture. After the field undergoes winter rain, snow, and freezing, when it thaws the following spring, the surface soil often becomes compacted. Therefore, around "Jingzhe," before the seedlings emerge, lightly rake over it once with an iron rake to settle the soil and facilitate seedling emergence. If the soil is too wet, it must not be compacted.
4. Thinning and final singling of seedlings
After the seedlings emerge, you can use a small hook to lightly break the surface crust, and combine this with clearing weeds, so that the surface soil is loosened to facilitate seedling growth. When the seedlings grow 2-3 true leaves, carry out thinning by the triangular seedling-spacing method, with a plant spacing of about 3 cm. If too sparse, the roots are thick and loose in texture, and the quality is poor; if too dense, growth is poor.
3. Differences between Adenophora stricta and Glehnia littoralis
Although Adenophora stricta and Glehnia littoralis are two kinds of plant medicinal materials from different families and genera, Glehnia littoralis is the root of the Umbelliferae plant Glehnia littoralis; Adenophora stricta is the root of the Campanulaceae plant Adenophora stricta. However, it is generally believed that the two medicines have similar functions, but when distinguished in detail, Adenophora stricta is more inclined to clear the lungs and resolve phlegm, while Glehnia littoralis is more inclined to nourish the stomach and promote fluid production.
Their sources are different: "Glehnia littoralis" is the root of the Umbelliferae plant Glehnia littoralis; "Adenophora stricta" is the root of the Campanulaceae plant Adenophora stricta. "Adenophora stricta" is also called "Pao shen," and is light and loose in texture. The usage is the same, and the difference is not great; both are yin-nourishing medicines!
After reading the above, everyone can also know that for Glehnia littoralis seeds, it is best to choose fresh seeds with fuller grains, a glossy surface, and a purple-blue color. In addition, if you do not know how to raise seedlings, you can also learn some of the methods shared by the editor above. I hope this article can help everyone!
