Investigation and Evaluation of Cultivation Status of Ligusticum chuanxiong in Sichuan / 中国实验方剂学杂志

ABSTRACT

Objective:To deeply understand important scientific problems and key technical problems in the cultivation of Chuanxiong, the Chuanxiong cultivation situation of 247 households in 23 towns of 5 counties in Sichuan province were investigated, providing basic data for the standardized cultivation of Chuanxiong. Method:On the basis of reported literatures, a questionnaire survey was conducted on the farmers of cultivating Chuanxiong in main producing areas, field measurements were also preformed, and the cultivation status of Chuanxiong was comprehensively analyzed. Result:The proportion of plain-breeding mainly existed in Pengzhou and Shifang, where per farmer had a small scale of planting areas, was 65%, while the proportion of mountain-breeding mainly existed in Meishan, Qionglai and Dujiangyan, where per proprietor had a large scale of planting areas, was 92%. The planting density and yield of Chuanxiong varied greatly among individuals. The growth period of Chuanxiong in Meishan and Qionglai is about 30 days shorter than that in Pengzhou, Shifang and Dujiangyan. About half of farmers applied base fertilizer and top dressing in spring. The proportion of NPK compound fertilizer input was high (>90%). Chuangxiong has a few diseases and insect pests, the incidence of which in new production areas was obviously lower than that in old production areas. The application of herbicide was not standardized. 52% farmers used Chu cao ling No.1 which was made by agricultural material store owners. The labor cost accounted for the highest proportion (37%) in Chuanxiong cultivation. Conclusion:Now in Sichuan clonal propagated patterns of Chuanxiong were both mountain-breeding and plain-breeding. It is suggested to make clear the differences between mountain-breeding nodes and plain-breeding nodes, and breed high qualities of Chuanxiong nodes. The mechanization research and production of Chuanxiong should be promoted, realizing timely planting and harvesting. Farmers should be guided to increase the application of organic fertilizer, and meanwhile standardize the application of agrochemicals.
