摘要
在中等黑土上进行了花生基因型筛选试验，以提高小麦的利用率。从本实验中，四种不同的硫源，即石膏、SSP、FeSO4和ZnSO4，以四个水平(S @ 0、20、30和40 kg ha-1)施用。结果表明，无论花生基因型如何，添加40 kg S ha-1作为FeSO4均可显著提高花生干物质产量和硫吸收量。硫以SSP的形式施用增加了根长和每株荚果数。花生基因型CO7、VRI 8和TMV 14为高效S利用型，BSR 2和ALR 3为低效S利用型。
Screening of Groundnut Genotypes for Sulphur Utilization Potential
A microplot experiment was conducted on a medium black soil for screening of groundnut genotypes for improved S utilization. From this experiment four different S sources viz., Gypsum, SSP, FeSO4, and ZnSO4, were applied at four levels (S @ 0, 20, 30, and 40 kg ha-1). The results revealed that the addition of 40 kg S ha-1 as FeSO4 substantially increased the dry matter production and sulphur uptake irrespective of groundnut genotypes. Sulphur application in the form of SSP enhanced the root length and number of pods per plant. Groundnut genotypes CO7, VRI 8, and TMV 14 were categorized as efficient S utilizers, while BSR 2 and ALR 3 were recorded to be inefficient S utilizers.
