| In order to improve the yield and quality of Rhizoma menispermi, effects of different cultivation mode (humping support,pinching and natural growth) and harvest time on the growth，yield and quality of R.Menispermi were studied by trait investigation and acidbase titration. The result showed that the humping support significantly increased the yield and promoted growth, increased the yield by51.88%, and promoted the growth of root diameter, leaf width, leaf length, stem diameter significantly. The content of whole alkaloid in humping support cultivation mode didn't significantly increased, but was higher than in pinching and natural growth cultivation mode. In the investigated harvest time,the discount rate and content of whole alkaloid in 4 years old R. Menispermi insignificantly increased than in 2,3 years old. The discount rate and content of whole alkaloid slowly increased during the harvest time.There was no significantly difference from early october to frozen.The result indicated that the humping support was an effective way to increase the yield and improve the quality of R.Menispermi, and the optimum harvest time was from early october to frozen. |
