【摘要】 对花生的硫素营养特性进行了研究 ,结果表明 :施硫均能显著提高花生各生育阶段对N、S的吸收量 ,提高其N、S含量 ,降低N S比 ,提高花生盛花期以后的N积累比例 ,明显促进S养分向花生籽实部分运转。在不同硫肥品种中 ,以石膏促进花生吸收N、S,提高其N、S含量的效果最好。花生在始花～盛花期吸收硫的强度最大更多还原

【Abstract】 The characteristics of sulphur nutrition in peanut plant were studied, the results indicated that sulphur application could significantly increase nitrogen and sulphur uptake by peanut plant at various growth stages, enhance nitrogen and sulphur content, decrease the ratio of nitrogen to sulphur, raise the accumulation of nitrogen in plant after peak flowering, promote the transportation of sulphur from leaves to peanut seeds. Among tested three sulphur fertilizers, gypsum had the best effects on the absorption and accumulation of nitrogen and sulphur. The strength of sulphur uptake by peanut plant during initial flowering～peak flowering was the maximum.更多还原
