摘　　要：1995～ 1 996年进行的田间和盆栽试验表明 ,硫氮或硫硼配施可以显著增加菜籽产量 .硫氮配施比对照增产 1 0 8 2～ 3 1 4 0kg/hm2 和 5 5～ 1 9 6% ,硫硼配施比对照增产 83 4～ 2 4 8 2kg/hm2 和 6 9～2 3 1 % .施硫可以增加油菜植株体内的硫含量并改善其硫素营养 ;在缺硫土壤上施硫可以降低菜籽硫甙及芥酸含量 ,提高油酸含量 ,因此有改善菜籽品质的作用 .Field and pot experiments were conducted in 1995-1996. The application of sulphur in combination with nitrogen or boron significantly increased the yield of rapeseed. By applying sulphur and nitrogen, the seed yield increased by 108.2 to 314.0kg/hm 2 or 5.5 to 19.6%. By applying sulphur and boron, the seed yield increased by 83.4 to 248.2kg/hm 2 or 6.9-23.1%. The sulphur applying can greatly improve rape sulphur nutrition and increase S contents in the plant. The sulphur applying can decrease the content of glucosinolates and eruic acid, but increase the content of oleic acid in the seed under S-deficiency in soil. This is an evident of quality improvement of the seed.
