目的：探讨影响半夏产量的因素和寻求解决该问题的关键技术。方法：四川是半夏的道地产区，通过四川阆中半夏基地多年生产、实验结果并兼顾周边其它区域的生产情况，对半夏生产过程中，影响其产量的各个因素进行比较分析。结果：发现品种品质、播种期、密度、肥料、采收期、产地生态环境等是影响半夏产量的重要因素。结论：半夏栽培中有诸多因素影响其产量，因此要根据半夏的生物学特性，结合种植区域地理环境特点，合理种植，科学管理，才能实现其稳定高产。

This study aimed to analyze the factors influencing the production of Pinellia ternate, and tried to find out the key technique to improve its yield. Sichuan is the original producing area of P. ternate. By surveying the long-term production of P. ternate at the Langzhong Base and in the adjacent areas, together with the experimental results, the factors influencing the yield of P. ternate were comparatively analyzed. The results showed that various factors, such as species and quality of P. ternate，seeding time, density, fertilizers, harvesting time, and the ecological environment of the producing area, have significant influence on the yield. Therefore, to gain stable and high yield of P. ternate, more attention should be paid to the biological characteristics of P. ternate, the geological feathure of the planting area, rational culture and scientific management.
