以清水旱半夏为材料，观察了种球大小及播深对半夏产量与珠芽腐烂率的影响。结果表明，半夏产量与播种深度和种球大小之间具有显著的线性关系，产量与播深呈负相关，与种球大小呈正相关；珠芽腐烂程度随播深、种球的增大而加重。

We use Pinellia species of Qinshui as test materials to studied the effect of bulb size and sowing depth on yield and decay rate in Pinellia ternate. The results showed that there was the significant linear relationship between Pinellia yield and sowing depth and size of the bulb， there was negatively correlated yield and sowing depth Pinellia and a positively correlated between yield and the size of the bulb. The decay of bulbil with the increase of sowing depth and the bulbs increases.
