Abstract


Cistanche (Cistanche deserticola YC Ma) to obligate root parasite, host of Haloxylon (Haloxylon ammodendron (CAMey.) Bunge). Through this experiment, inoculation technique and stubble Cistanche picking methods such as research aimed at improving vaccination rates Cistanche and yield; Cistanche inflorescence growing by ambient temperature, moisture variation research, promote inflorescence growth and development, improve seed quality . The main conclusions are as follows: 1. At different soil depths, Cistanche vaccination rates are different. 60 cm of soil depth vaccination Cistanche, can effectively improve Cistanche coverage, vaccination rate was 70.9%; followed 45cm depth vaccination, inoculation rate was 66.81%; 30cm, 75cm soil layer at the vaccination rates were lower, at 55.45 %, 37.27%. 2 inoculation tests showed different levels of distance: horizontal distance at 40 cm at Cistanche vaccination rates up 80%, 50 cm horizontal distance coverage was 71.81%; distance trunk 10cm Cistanche vaccination at the lowest rate of only 45 %. 3 different inoculation time of inoculation experiments show that: April ~ May vaccination, Cistanche vaccination rate 71.36%; July to August vaccination coverage was 60%. Thus, in April to May is an ideal time for vaccination. 4 different fertilization methods on Cistanche vaccination rate of experiments show that: organic fertilizer applied every time, Cistanche vaccination rate is highest, up to 82.27%, while organic fertilizer mixed fertilizer, Cistanche coverage was 75.09%, organic manure on the vaccination rate applied a minimum of 58.63%. 5 using the year then inoculated host plant Cistanche is feasible, vaccination survival rate of 67.6% ~ 75.2%. And inoculated with acupuncture method of paper higher than vaccination, inoculation inoculation rate is higher than ditching paper method. 6 different stubble height treatment test showed that: stubble height of 15cm and 20cm handle the number of processed Cistanche germination were 7.65 and 8.96, higher than 5cm and 10cm handle processing 2.35 5.97. Stubble height of 15cm processing plant Cistanche weight 1.51kg, 20cm higher than the handling 0.3kg. Therefore, in the stem at 15cm above the parasitic disc stubble, Cistanche germination number more, the highest yield per plant. 7.10cm fleshy stems above all harvesting, mining big to stay small, flat stubble height of 15cm three treatments on the yield of Cistanche show: 15cm stubble height treatment Cistanche highest yield; mining yield big to stay small processing center, 10cm or more succulent All stem lowest yield harvest handling. 8 Environmental Conditions on the Growth of Cistanche inflorescence experiments show that: Cistanche inflorescence growth and air temperature and soil temperature is closely related to the general atmospheric temperature 20 ℃ ~ 30 ℃, soil temperature at 15 ℃ ~ 20 ℃, soil volumetric water content 3% to 4%, the fastest growth rate of up to 2 ~ 3cm / d. 9 Effective component analysis showed that: in color, odor and impurities detection, Cistanche fully comply with the provisions of the indicators of Chinese Pharmacopoeia, Echinacoside, verbascoside detection levels are up to 20.17%, 7.12%, significantly exceeded the pharmacopoeia standards, and Cistanche in the water, alcohol materials, the detection of total ash content, do not exceed the requirements of Pharmacopoeia.
