Objective:

2

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:

2

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:

2

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:

2

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.
