Cultivation method for bletilla striata seed stems

Abstract

The invention discloses a cultivation method for bletilla striata seed stems. The bletilla striata seed stems which can be directly sowed to the field are cultivated by the domestication of bletilla striata tissue culture tubers for 4-6 months, effective, high-yield and high-quality seedlings (seed stems) are provided for artificial cultivation of bletilla striata, common farmer households can directly sow the bletilla striata seed stems to the field, the yield per mu of fresh products of bletilla striata medicinal materials can reach 1,000-1,500kg after 3-4 years according to a standardized planting technical regulation, and the output value per mu is 100,000-150,000 RMB according to a current price. According to the method, the bottleneck problem of restriction of a large-scale bletilla striata production core technology is solved, the bletilla striata can be truly and artificially produced, rare medicinal resources are protected, and raw material guarantee is provided for industrialization development of the bletilla striata.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for cultivating bletilla seed stems. Background technique [0002] The rare and precious medicinal material Baiji is the orchid plant Baiji ( Bletilla striata ) of dried tubers. Baiji is a small perennial herb. Due to its high medicinal value and continuous expansion of industrial uses, the market demand is increasing year by year. The market supply mainly depends on wild resources. At present, it is rare to have a planting base of more than 100 mu. The price has continued to rise nearly 100 times, reaching 500 yuan / kg. It is one of the very few rare medicinal materials that only increases in price and does not superimpose. Wild resources have been destructively excavated, and wild resources are endangered. They are listed as rare and endangered plants in the country for protection, and are also included in Appendix II of the Convention on International Trade (CI...

Problems solved by technology

[0003] Carrying out artificial cultivation is the most effective way to meet market demand and protect white and resources, but according to the report and analysis of "National Medicinal Materials Information" (2013), although there have been reports of successful planting and planting of white in recent years, the overall scale is not large , more than 100 acres are very rare, and so far no home-grown products have been listed for sale, and the planting technology has not really made a breakthrough

The main technical bottleneck problem is the scarcity of high-yield and high-quality seedlings. At present, there are technical bottlenecks in the technology of cultivating seedlings by tissue culture and rapid propagation technology. If the tissue culture seedlings are cultivated in a conventional way, it seems that a large number of seedlings can be obtained. However, after these seedlings go to the ground, it is either difficult to form tubers, or the tubers are small and grow very slowly, and it is difficult to obtain yield after planting. This is also the core problem that has been difficult to popularize for many years. It is also the key to the lack of large-scale planting bases and technical bottlenecks. Has not broken through
