图1 不同土壤磷及叶面磷处理下花生根系形态特性 标以不同小写字母的柱值于处理间0.05水平上差异显著。CK: 对照; P 0.1%: 喷施0.1%叶面磷肥; P 0.2%: 喷施0.2%叶面磷肥; PA: 土壤充足供磷; PD: 土壤磷胁迫; PS: 结荚期; PF: 饱果期; HS: 收获期。

Fig. 1 Root morphology characteristics of peanut under different P application rates in soil and leaves Bars superscripted by different letters are significantly different at the 0.05 probability level among treatments. CK: control; P 0.1%: spraying 0.1% P fertilizer; P 0.2%: spraying 0.2% P fertilizer; PA: adequate P in soil; PD: P deficiency in soil; PS: pod setting stage; PF: pod fulling stage; HS: harvest stage.
