The latest method of propagation of Glehnia

Glehnia littoralis is the root of coralline vegetables of Umbelliferae. After processing and drying, it is used for medicinal purposes. It has the effects of moistening lungs and relieving cough, nourishing stomach and promoting body fluid. It is used for lung dryness, dry cough, fever, thirst and other diseases. It has strong adaptability to climate. It likes sunny and warm humid environment. It is mainly produced in Laiyang, Weifang, Hebei, Liaoning and other places. Let's take a look at the breeding methods of Glehnia littoralis.

Seed Treatment of Glehnia littoralis

Glehnia littoralis is a deep-rooted plant. Before sowing, it should be deeply ploughed and raked flat. Before planting, it should be connected with seeds and fruit wings. Soak them in warm water of 25 ℃ for 4 hours. Take them out and cool them slightly. Mix them with two-thirds wet sand. Put them into boxes and freeze them. After thawing in spring, seed them. Autumn sowing should be sown before freezing. Spring sowing seeds should not be stored in sand. Otherwise, they cannot emerge in that year.

The seed method of Northern Glehnia

Autumn sowing according to the row spacing 5-6 cm to draw a shallow ditch half a cm deep, seeds and seeds 4-5 cm apart from soil watering, covered with straw, before freezing again irrigated with water, covered with a layer of manure, spring sowing in Qingming to grain rain before and after, the same method, seeds do not need low temperature freezing treatment, do not emerge after planting, if not treated, it is best to harvest immediately sowing, sandy soil per hectare sowing quantity 75 kg, pure sandy land per hectare 90-112.5 kg, Fertile soil with irrigation conditions can be sown 52.5-60 kg per hectare. After sowing, pure sandy land is suppressed with yellow mud or small crisp stones to avoid loss caused by wind-blown sand movement. Sand should be suppressed when waterlogging depression is frozen. Seeds sown in autumn will emerge in March of the next year.

Management of Glehnia littoralis seedlings

1, winter and spring management: Glehnia winter sowing, in winter snow to the ground after moving snow, conducive to moisture conservation, ginseng field by winter rain and snow freezing, the next spring thaw, topsoil often appear hardened, therefore, before and after the "Jingzhe", seedlings unearthed, gently swing with iron rake, so that the soil is solid, in order to facilitate emergence, such as soil too wet can not be suppressed.

2. Thinning seedlings: After the ginseng seedlings are unearthed, they can be gently scratched by small grappling hooks, and combined with clearing weeds, so that the topsoil is loose to facilitate the growth of seedlings. When the ginseng seedlings grow 2-3 true leaves, they are thinned according to the triangular seedling retention method. The plant spacing is about 3 cm. The roots of the ginseng are thick and loose, and the quality is not good. If they are too dense, they will grow poorly.

3, drainage irrigation: Glehnia littoralis drought resistance is strong, the most afraid of waterlogging, general mild spring drought, conducive to root growth downward, deep roots. Spring waterlogging, ginseng roots grow slowly, roots are thick and short, so there is a saying of "spring waterlogging, not out of the article", spring in case of severe drought, can be properly watered, to irrigate the ground for the degree, in the late growth of Glehnia littoralis and rainy season, special attention should be paid to timely drainage of water, to prevent rotten roots.

4. Reasonable topdressing: after the seedling of Glehnia littoralis, 50 kg of fermented bean cake fertilizer can be applied per mu, 1 kg of trichlorfon powder can be mixed in the fertilizer, scattered between rows, then loosened and watered. Before and after the "small heat", urea can be applied per mu before the rain. 10-15 kg. When buds appear in a year, they should be removed in time to promote the growth of roots.
