- 摘要:
- 以景天三七为试材,利用正交实验设计,研究了育苗期、栽培密度、纯氮使用量、K2O使用量4个主要栽培因子对景天三七产量的影响,以提高景天三七在黔西北地区的增产潜力。结果表明:最佳育苗期为4月15日;最佳栽培密度为15 cm×15 cm;配施纯氮最佳使用量为30 kg/667m2、K2O用量为20 kg/667m2。
- Abstract:
- Taking Sedum aizoon L.as material,the effect of sowing date,planting density,the amount of N,the amount of K2O on the yield of Sedum aizoon L.were studied by the design of orthogonal design,in order to improve the potential of Sedum aizoon L.in Northwestern Guizhou yield.The results showed that,the best sowing date was April 15th,the best planting density was 15 cm×15 cm,the better amount of N was 30 kg/667m2,the better amount of K2O was 20 kg/667m2.
