摘　　要：为探究生物炭施用量对甘薯生长发育的影响,采用盆栽试验(生物碳施用量为0、0.75%、1.1%、1.5%)和田间试验(生物碳施用量为0、20、30、40 t/hm^(2)),测定甘薯生长、生理指标及产量。结果表明,生物炭能够增加甘薯的茎粗、茎长、叶面积;提高甘薯叶片的光合特性,提高甘薯叶绿素含量、SOD和POD活性、根系活力。处理Ⅳ的大、中薯数以及产量与对照差异显著,在大、中薯重和平均单株产量方面各处理差异不显著。生物炭施用量以40 t/hm^(2)甘薯的长势最好,生理指标表现最好,产量最高。To explore the effects of biochar application rates on the growth and development of sweet potato.The study used pot experiment(0,0.75%,1.1%,1.5%)and field experiment(0,20,30,40 t/ha)to study the growth,physiological indicators and yield of sweet potato.The results showed that biochar can increase the stem thickness,stem length and leaf area of sweet potato,improve the photosynthetic characteristics of sweet potato leaves,increase the chlorophyll content,SOD and POD activity of sweet potato,and increase root vigor.Treatment IV had significant differences in the number of large and medium potatoes and the yield of the plot from the control,but the differences in the weight of large and medium potatoes and the average yield per plant were not significant.The biochar applica⁃tion rate of 40 t/ha sweet potato has the best growth,the best physiological indicators and the highest yield.
