Dendrobe seedling culture technology

Abstract

The invention relates to a dendrobe seedling culture method and belongs to the technical field of agricultural planting. The dendrobe seedling culture method comprises the steps of selecting a seedbed, preparing a substrate, soaking seeds and planting, wherein the step of soaking the seeds is to soak the dendrobe seeds into a carbon dioxide Gans solution and then plant the seeds; the dendrobe seeds adopt seeds which are not cracked, the seeds are subjected to surface sterilization treatment by an alcohol solution of 75 vol%, the seeds are taken out and soaked into the carbon dioxide Gans solution, and the mass ratio of the seeds to the solution is (20-30):(900-1005); and the step of preparing the substrate is to uniformly mix cow dung, rice soup and salt according to the mass ratio being (80-110):(3-7):(40-60), perform sealed fermentation for 25 to 30 days, add clean water with the corresponding mass parts being 40 to 60 before use, dilute and filter for future use. The method is simple in operation, and the obtained plants have high germination rate, long repeated growth cycle, high disease resistance, rapid growth and high transplanting survival rate.

Description

technical field [0001] The invention relates to a technique for growing seedlings of dendrobium, belonging to the technical field of agricultural planting. Background technique [0002] Dendrobium is also known as hanging orchid, flat grass, yellow grass, etc. It is derived from the perennial epiphytic herb of Dendrobium orchidaceae. Distributed in Sichuan, Guizhou, Yunnan, Guangdong, Guangxi, Taiwan and other provinces and autonomous regions. There are more than 300 species of Dendrobium, and there are more than 70 species in my country, of which more than 20 are medicinal, mostly wild. Dendrobium is used as medicine with stems, which contain various alkaloids, mucus, starch, etc. Sweet, light, slightly cold in nature; nourishing yin and nourishing the stomach, clearing away heat and promoting body fluid, and mainly treating diseases caused by heat and body fluid, dry mouth and thirst, and post-illness deficiency-heat. Recent studies have shown that Dendrobium polysacch...

Problems solved by technology

[0004] Dendrobium plants are slow-growing plants. The number of new shoots produced each year is small and the growth volume is small. Moreover, Dendrobium has strict requirements on the growth environment. poor ability

There are many researches on the planting of Dendrobium, but due to limited planting conditions and techniques, the artificial planting of Dendrobium takes a long time to grow, the survival rate is low, and it is difficult to promote industrialization
