Method for breeding gentiana macrophylla low-altitude sound seedlings

Abstract

The invention discloses a method for breeding gentiana macrophylla low-altitude sound seedlings. The method comprises the following steps of selecting the seedling raising site and time; treating seeds, selecting the seeds harvested in the current year, soaking the seeds in 200mg/kg gibberellin for 24 hours, flushing and cleaning by tapping water, and airing for standby use; preparing a seedling bed; seeding; covering films and sunshade nets; weeding; and applying fertilizer. By utilizing the characteristic that the air temperature in winter is higher in the low-altitude areas, the areas are suitable for the growth and safe overwintering of the gentiana macrophylla seedlings, the low-altitude seedling raising in autumn and winter is utilized, the seedlings are carried to the high mountains to be planted in the next year, the growing process of the gentiana macrophylla is accelerated, and the four-year harvesting after planting is advanced to the three-year harvesting. Meanwhile, the conditions of flat dam areas, such as irrigation, are good, the technique popularizing degree is high, the farmer seedling raising technique is good, and the management is convenient, so a scaled seedling breeding base is easily established for breeding high-quality seedlings in the plateau areas, and the healthy development of the gentiana macrophylla of Tibetan medicines is promoted.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant cultivation, and in particular relates to a method for breeding strong seedlings of Gentiana chinensis at low altitude. Background technique [0002] Gentiana is an important traditional Chinese and Tibetan medicinal material in my country. Wild resources are far from meeting the needs of traditional Chinese medicine. Strengthening the research and demonstration of wild mutant species is an important measure for the protection and sustainable use of Gentiana resources. Due to the long growth cycle of Gentiana chinensis, the difficulty in seedling propagation, low input and output benefits, and the slow development of wild variants, the development of Gentiana chinensis has been affected. [0003] Perennial alpine medicinal materials such as Gentiana chinensis grow slowly in the early stage, and the seedling stage lasts for 5-6 months. It takes one year to raise seedlings and reproduce in t...
