Abstract

The invention relates to a seedling culture method capable of improving emergence rate of gentiana crassicaulis, belonging to the technical field of medicinal plant cultivation. The seedling culture method comprises the following steps: seedlings are cultured at altitude of 2200-2600m and transplanted at altitude of 2200-3300m; flat ground with deep and fertile soil layers or gentle slope with deep and fertile soil layers is used for culturing the seedlings; then the whole ground is ridged and covered with a film; before seeding, the seeds are soaked with clean water at 20 DEG C for 24 hours or with 50ppm gibberellin for 2-8 hours; the land plot with rust diseases or root rot diseases is subjected to seed disinfection; after soaking or disinfection, wet sands are mixed with the seeds to be processed for 20-30 days; after the seeds are processed, the film is uncovered; grass on the ground is removed; and the ridged surface is leveled; the seeds are sown at low density; after sowing, the ground is covered with mixed soil and pine leaves; 7-8 months later, fertilizer is applied to the ground for 2-3 times, and Bordeaux mixture is sprayed. The seedling culture method has the advantages that the emergence rate of the gentiana crassicaulis can be increased to 65-94%; diseases at a seedling stage can be relieved; and seedling quality and strong seedling output rate can be improved.

Description

Technical field: [0001] The invention relates to a method for raising seedlings for improving the emergence rate of Gentiana thick stems, belonging to the technical field of medicinal plant cultivation. technical background: [0002] Gentiana crassicaulis Duthie ex Burk. is a perennial herbaceous plant of Gentianaceae. One of the original plants. Gentiana chinensis is one of the important traditional Chinese medicines in my country. It is mainly used to treat rheumatic arthralgia, asthenic hot flashes, jaundice and other diseases. In the medicinal history of more than 2,000 years, Gentiana chinensis was mainly used as wild products. Due to the year-by-year deterioration of the habitat, serious population degradation, and destructive digging, the resources of wild Gentiana chinensis are decreasing year by year, and it is listed as a national third-level key protected plant among the national key protected medicinal plant species. In recent decades, the thick-stemmed Gentia...
