Abstract:

For the clarification of the production laws of raising seedlings of Tripterygium Wifordill and better grasping the main factors for the greenhouse effect to raise seedlings of Tripterygium Wifordill and increase the quantity and quality of this research by experimental field, the growth laws of raising seedlings of Tripterygium Wifordill in greenhouse and daejeon were on the observation, and the main factors in the regulatory approach was adopted in the greenhouse raise seedling. Thus, the results showed that: firstly, the breedproductive regularity of nursing young plants in greenhouses was nearly the same as in field growing. The yearly growing period was 252 days. Secondly, Tripterygium Wifordill had better resistance to shade. The proper shade of nursing young plants in greenhouses was good for growing. 50% of shading degree was better. Thirdly, moist environment benefited growing of Tripterygium Wifordill. Moisture content had great effect on Tripterygium Wifordill breed growing in greenhouse. The height of 1400 mm water supply was the best. Fourthly, the demands of growing environment were to avoid strong wind and evaporation. Fifthly, less range of temperature was of benefit to Tripterygium Wifordill growing. The paper could reach a general conclusion according to the above experiment: major meteorological factors had important effect upon Tripterygium Wifordill growing. In the process of nursing young plants of Tripterygium Wifordill in greenhouse, midde sunshade, greater water supply, less wind, less range of temperature and other reasonable controls did good to the quality and production of Tripterygium Wifordill.
