Background data: Dendrobium huoshanense is an evergreen herb with perennial stems in Orchidaceae, which has strict requirements on the environment and is mostly epiphytic. In the wild, it is mostly distributed in the low mountainous areas of 300 ~ 700 meters, growing on the cliffs beside the river valley, in a cool, humid and ventilated environment. Dendrobium contains many components, such as dendrobine, dendrobium polysaccharide and so on. It has many functions, such as anti-bacteria, lowering blood pressure and inhibiting the growth of tumor cells. It has a miraculous effect on improving human immunity and prolonging life. It is a precious Chinese herbal medicine and a foreign trade export substance. Dendrobium in Hong Kong market is equal to gold, and the international price of its processed product "Fengdou" is 8000 ~ 10000 USD/kg, which is known as "thousand flowers and plants" and "soft gold". Dendrobium has great economic and medicinal value, and its development prospect is very broad. The areas suitable for planting Dendrobium are Dabie Mountain area in our province and mountainous area in southern Anhui. In addition, it is also suitable for industrial rapid propagation and greenhouse cultivation.
Project outline: Through the research on the ecological environment, physiological and biochemical characteristics of Dendrobium huoshanense, a set of efficient propagation technology system of Dendrobium huoshanense seedlings was established, and the annual propagation coefficient of seedlings reached 12. The "Dendrobium nutrient solution" was independently developed, the extraction and purification methods of Dendrobium polysaccharide, the main effective component of Dendrobium huoshanense, and its antioxidant effect were established, and the development of series products of Dendrobium huoshanense, fine Dendrobium huoshanense polysaccharide and Dendrobium huoshanense beverage was established. The research of this project has reached the leading level in China, and it has the germplasm reserve and technical conditions for industrial production.
3. In 2006, Anhui Province won the third prize of scientific and technological progress "Gastrodia elata Propagation and Transplanting Technology" (ranked first).
BACKGROUND: The growth of Gastrodia elata is suitable for popularization in mountainous areas of Anhui Province, and it can also be cultivated under indoor control. Gastrodia elata is a precious medicinal material. As a medicinal plant, it can not only treat a variety of diseases, but also be a good advanced health tonic. According to different dosage forms, it has high medicinal value, unlimited development prospects and huge market potential.
Project Description: In this study, shoot tips, rice hemp and white hemp seeds were used as explants, and rice hemp in vitro was used as seed hemp. The optimum culture conditions were screened out, and a complete set of high-efficiency propagation technology system of test-tube rice flax was established, which simplified the propagation procedure of seed flax in production and developed a set of methods for separation, purification and rapid determination of gastrodin content. This technology can be used to identify the quality of Gastrodia elata.
Achievement level: This project is the tenth five-year major scientific and technological project in Anhui Province. In 2006, it passed the acceptance of Anhui Education Department and won the third prize of Anhui Science and Technology. According to the characteristics that Gastrodia elata can absorb the second nutrient source, combined with the tissue culture requirements of Orchidaceae plants, a set of technical scheme of non-growth propagation and transplanting of Gastrodia elata seed hemp was formed, which was a new breakthrough in the production and large-scale cultivation and development of Gastrodia elata seed hemp. The technical system established in this project is perfect, among which the technology of inducing protocorm growth without germination of gastrodia elata seeds and the technology of transplanting rice and hemp have reached the leading level at home and abroad.
4. In 2008, Hefei won the third prize of scientific and technological progress, "Study on the Utilization of Germplasm Resources and High-yield Cultivation Model of Protected Tomato in Israel" (ranked first).
In 2007, the achievements of this project were recognized as leading in China. The introduction experiment of Israeli tomato varieties F-409 and F-044 was carried out, and the adaptability of Israeli tomato varieties F-044 and F-409 planted in middle-fat areas was systematically observed from the aspects of tomato plant growth and development characteristics, flowering and fruiting characteristics, fruit quality characteristics and yield characteristics. On this basis, a set of high-yield and high-quality cultivation techniques suitable for this variety were summarized, and two tomato hybrid combinations with high yield, disease resistance and storage resistance were cultivated.
5. In cooperation with Xinjin Dendrobium candidum Development Co., Ltd., new Dendrobium candidum varieties Wan Hu 1 and Wan Hu No.2 were bred.
6. Identification of the cultivation effect of drought-resistant and salt-tolerant perennial ryegrass.
As a pasture, the variety of this project grows well in the area with precipitation of 500- 1000mm, with excellent texture and good palatability, with a yield of 3000-4000kg；; Fresh grass per mu; As lawn grass, it has fast turf formation and low pruning resistance. Compared with the original variety, it has strong drought tolerance and greatly improved disease resistance. The drought water-saving test of mutant plants and small-scale drought stress test in the field showed that the growth potential of ryegrass mutant plants was obviously better than that of control plants under drought conditions.
