摘要: 于1986~1988年对夏播芝麻氮、磷、钾肥的施用量,合理配比及使用方法进行了研究,结果表明,河南省夏芝麻产区的土壤肥力差异较大,必须因土施肥。一般施肥量应为:N90~120kg/hm2,P2O545~60kg/hm2。土壤速效钾含量120mg/kg为施钾临界值,低于此值时施钾有效。施肥方法以氮肥底施加追肥,磷、钾肥全部底施的增产效果最好。土壤中Fe、Mn、Cu等微量元素尚能满足芝麻需求,但Zn、Mo、B表现出潜在缺乏,应予补施,以促进芝麻营养的平衡吸收。

Abstract: The rational rates and methods of N,P and K fertilisers for summer sesame weredled,understanding on the basis of the rules of nutritive absorption and dry matteraccumulation.The status of some kinds of trace elements anti its fertilization were studiedsimultaneously.The results indicated.that fertilization according to soil fertility should be rephasized because of the larger difference of soil fertility in sesame production area.
