| Dendrobium candidum is a commonly used rare traditional Chinese medicine, with Ziyin lungs, brain, Liver eyesight, Qingxin, physical fitness, anti-cancer, enhancing immunity, the treatment of pharyngitis and other effects. Because of its very slow growth of the natural conditions,add long widely exploitation destruction of wildlife resources Facing the more desperate wild Dendrobium, highlight the contradiction between supply and demand, make it difficult to develop health industry of Dendrobium candidum. People trying to promote growth and reproduction of plants or artificial cultivation, but driven by the interests of the majority of enterprises, using conventional crop planting method, long-term application of fertilizer and pesticide in order to improve the yield, the declining quality of medicinal dendrobium. Therefore, improving the existing mode of production and management technology of artificial cultivation, optimize, developed a new type of short period, high efficiency, sustainable development of production management techniques, to produce high-quality seedlings.By using four different cultivation techniques of high bed, stereo elevated, original ecological elevated, between the environment and the cultivation of wild jujube planting clear growth of Dendrobium candidum imitating the dynamic relationship between scale and quality, artificial cultivation of Dendrobium growth can mediate controllable effective environment, cultivation technology to get the best benefits. Therefore, this paper discusses the effect of four kinds of different growth and polysaccharide content of cultivation mode of high bed, stereo elevated, elevated the original ecological planting jujube, imitation of the wild Dendrobium candidum, and benefit analysis.Based on the good growth, no insects were cultivated in greenhouse, a year in Yandang Mountain red stem of Dendrobium candidum as raw material,40-60% of shading in the relative humidity around 75%, about 25℃ temperature, ambient conditions, comparative analysis of 3 kinds of high bed, stereo elevated, elevated the original ecological planting techniques in greenhouse, and no shading and imitation of the wild jujube planting mode of growth, the content of polysaccharide and benefits.Through the research on the measurement of growth and polysaccharide content of Dendrobium candidum cultivation technology, through the analysis of benefit, the results of the paper:1. The different methods growth and polysaccharides content of Dendrobium candidum cultivation.4 kinds of method of cultivation, cultivation environment of 4 different,1.5y after planting, the obvious difference of the cultivation technology of growth and polysaccharide content. From the beautiful plant type, the most beautiful stereo viaduct close to the wild Dendrobium candidum. The longest diameter of high bed cultivation stem, average stem (25.07 ± 0.29) cm, the mean crude stem up to (0.63 ± 0.01) cm, due to the natural environmental factors like wild jujube, unstable growth, not one size, measured average height was (22.14 ± 0.64) cm, the mean diameter stem (0.51 ± 0.03) cm. The highest survival rate is high bed cultivation, as (99.3 ± 0.12) cm, fast growth,1.5y average long (18.9 ± 0.32) cm. The germination rate, high bed up to cultivation, as (90.3 ± 0.06)%. From the blossom rate, high bed cultivation faster than the other 3 cultivation techniques, as (97 ± 0.05)%. From the total output,1.5y high bed cultivation fresh yield the highest, up to (600 ± 1.15) kg, imitating wild jujube is lowest, (320 ± 2.89) kg. From the content of polysaccharide, stereo elevated significantly greater than the other 3 cultivation techniques of 1y and 1.5y, the average contents of polysaccharide were (18.56 ± 0.07)% and (20.1 ± 0.06)%.2. Cultivation of the different ages, different polysaccharides content of Dendrobium candidum.1.5y and 1.0y average content of polysaccharides were (20.10 ± 0.06)% and (18.56 ± 0.07)% stereo overhead, the average content of polysaccharide was (16.61 ± 0.11)% and (15.2 ± 0.06)% high bed cultivation, the average content of polysaccharides were (18.29 ± 0.11)%, (16.83 ± 0.11)% and (18.48 ± 0.09)% and (17.53 ± 0.1)% elevated original ecology and imitation of wild jujube cultivation seedling.4 cultivation technology content in one year half of the polysaccharide were higher than the annual, visible within a certain period of time the content of polysaccharide, and increased with time.3. Through the benefits of the Dendrobium candidum, In order to sell the stem of the plant for the purpose, recommended to choose the original ecological planting 1.5y elevated viaduct, the original ecology of the dry weight of maximum profit, as (114,820-126,820) element, high bed cultivation for lowest income, (3,550 ± 230) yuan; planting Dendrobium candidum to sell fresh for the purpose, the proposed election stereo high shelf stereo cultivation, elevated 1.5y fresh yield was (48,300 ± 345) element. Don’t suggest that there is no stable pin source to sell flowers of stem and fruit for the purpose of planting. Planting all products sold, suggestion choice of three-dimensional elevated cultivation. In general, three-dimensional elevated cultivation is the best benefit cultivation technology in these 4 kinds of cultivation techniques.In summary, the artificial cultivation of the seedlings Dendrobium candidum, in order to choose the best stereo overhead planting technology, the cultivation mode will obtain the best economic benefits. |
