不同氮、磷、钾配比对紫甘薯花青素积累及产量的影响
Effects of Different Nitrogen,Phosphorus,and Potassium Ratios on Anthocyanin Accumulation and Yield in Purple Sweetpotato
摘要
Abstract
To investigate the dynamic changes of anthocyanin accumulation and the effects on fresh tuber yield under three nitrogen,phosphorus,and potassium ratios,three purple sweetpotato varieties with different anthocyanin contents(Wanzishu 56,Ningzishu No.1,and Wanzishu No.16)were selected in this study.Three nitrogen,phosphorus,and potassium ratios were designed:1∶1∶1(B1,balanced ratio),1∶2∶1(B2,high phosphorus ratio),1∶1∶2(B3,high potassium ratio).The results showed that the average anthocyanin accumulation in the three purple sweetpotato varieties followed the order:B2>B3>B1.The variation trends of B2(high phosphorus)and B3(high potassium)were basically consistent,both were conducive to anthocyanin accumulation in purple sweetpotato,and B2 exerted a stronger promoting effect on anthocyanin accumulation at 60 and 140 days.The anthocyanin content of the three purple sweet potato varieties under the B2 was significantly higher than under the other ratios.The fresh tuber yield showed a trend of B2>B1>B3.The difference between B3 and B1 was significant in Wanzishu 56 and Wanzishu No.16,while the difference was not significant in Ningzishu No.1.关键词
