基于田间试验的不同处理甘蔗吸收S素养分参数研究OACSTPCD
Effect of Different Application Rate of Sulfur on the Yield of Sugarcane Based on a Field Experiment
在田间以不同处理进行甘蔗吸S试验，结果表明：不同处理间甘蔗吸收S素养分量为：1．16-1．54g／kg，且各处理间差异不显著；施用S素肥料对甘蔗有一定的增产效果，施s各处理比cKf不施s）增产1．12％～9．82％，以处理NPKS2施用量60kg／hm。效果较佳，增产9．82％。甘蔗S吸收量在1．16—1．21g／kg范围内与甘蔗产量呈正效应，过之则呈负效应；甘蔗吸收S素养分量的临界值为1．21g／kg；甘蔗施用s肥的当季肥料利用率为19．10％。
A field experiment was conducted to study the effect of different application rates of sulfur on the yield of sugarcane. The results showed that the sulfur uptake parameter of sugarcane was 1.16-1.54 g/kg and no significant differences were found between different treatments. Application of sulfur could increase the yield of sugarcane to some extent with increasing rate of 1.12%-9.82% compared to the treatment with no sulfur application （CK）. The highest yie…查看全部>>
