High-yield cultivation method of Gentiana straminea Maxim in Dongyuan of Qinghai-Tibet Plateau

Abstract

The invention discloses a high-yield cultivation method of Gentiana straminea Maxim in Dongyuan of the Qinghai-Tibet Plateau. The method comprises the following steps of: soaking seeds in warm water and treating the seeds in a moist environment at first, and then uniformly spreading mixture of palygorskite having a specification of 100-140 meshes, nitrogenous fertilizer, phosphatic fertilizer and potassic fertilizer in a ratio being 3000: 250: 150: 50 (kilograms per hectare) on the surface of soil; applying 30 tons of farmyard manure per hectare, and then deeply turning up the soil, finely harrowing and flatly grinding for sowing; sowing the treated seeds in the prepared soil and culturing young seedlings in May of the first year; and transplanting the young seedlings by a film-side furrow planting method from the end of April of the second year to the beginning of May of the next year, covering by black mulching films during transplanting, and performing proper field management steps, so as to obtain high-quality and high-yield Gentiana straminea Maxim.

Description

technical field [0001] The invention relates to a method for high-yield cultivation of Gentiana japonica on the eastern margin of the Qinghai-Tibet Plateau. Background technique [0002] Gentiana straminea Maxim. is a perennial plant belonging to the genus Gentianaceae of the family Gentianaceae. It is one of the herbal medicines commonly used by the Tibetan people. It is mainly distributed in the areas of the Qinghai-Tibet Plateau at an altitude of 2 000-4 950 m. The root is used as medicine, bitter, pungent, and flat in nature. It has the functions of dispelling rheumatism, reducing asthenic fever, relaxing tendons and relieving pain. It is used for rheumatic joint pain, tendon spasm, hot flashes due to tuberculosis, malnutrition and fever in children, jaundice, and dysuria. embolism. With the increase of dosage of Gentiana mahua in recent years, it is estimated that 10,000 tons of dry root products of Gentiana mahua will be needed annually. In addition to the large domes...

Problems solved by technology

Therefore, the wild species are now in a vicious cycle of "the more expensive the more you harvest, the more you harvest the more expensive". However, in recent years, the research on Gentiana twista at home and abroad has mainly focused on the chemical components, and there have been almost no reports on its cultivation techniques. , not to mention inventions in high-yield cultivation techniques

[0003] Under the severe situation that the wild resources of Gentiana are on the verge of extinction, a very important way to solve the shortage of raw materials of Gentiana in the future is large-scale artificial cultivation. At present, Gentiana has been artificially cultivated in the Dao production area on the eastern edge of the Qinghai-Tibet Plateau, but because there is no Guided by mature technology, the survival rate and yield of artificial cultivation are very low. Farmers and herdsmen are skeptical that the cultivation of Gentiana can bring considerable economic benefits. Artificial cultivation has not been continuously developed and expanded. In addition, most counties in this area The urban herdsmen account for the vast majority. They mainly live on nomadic herding. The planting mode is single, and they mainly plant highland barley. The farmers and herdsmen have no awareness of increasing economic income and improving their lives by planting cash crops. Therefore, the artificial cultivation of Gentiana twisted can not be scaled up.
