摘　　要：目的:研究种姜和播种方式对植株生长及郁金块根产量影响,为其规范化种植提供科学依据。方法:田间采用二因素裂区设计,齐苗后调查出苗数,定期调查株高,收获时测定小区产量,并对试验结果进行方差分析。结果:种姜对出苗数、株高和郁金块根产量都存在显著影响,不同播种方式对郁金块根产量无显著影响,两者间存在显著的互作效应。结论:窝播配合未发芽的具3～4节的子姜或母姜作种时,郁金块根产量最高。Objective: To provide a scientific basis for standardizing the cultivation method for Curcuma longa. Method: Plant heights and seeding numbers were sampled periodically, the plot yields were counted at harvested. Result: The effects of seeding method on yields, plant height and number were significant. The effects of different sowing ways on the yields were very little. Conclusion: The hole seeding method using mother tuber or blastostyle bearing three to four knots was shown to be the best may, worthy to be widely applied in production.
