摘　　要：在单核期对甘蓝型油菜CMS喷施新型化学杂交剂SX-1的同时加入尿素、速溶硼肥、磷酸二氢钾及其相互配组的肥料,结果表明:混喷尿素能明显提高油菜CMS叶片叶绿素含量、株高及株高日增长率;速溶B肥可明显增加单株有效角果数、主花序结角数、结角密度和产量;磷酸二氢钾仅在与速溶B肥配合使用时才可增加有效角果数;尿素和速溶B肥配合使用可明显增加叶片叶绿素含量,同时增产效果也最佳。化学杂交剂SX-1与肥料混合喷施可提高杂交油菜种子的质量和产量。A new type chemical hybridizing agents SX-1 and three kinds of fertilizer were mixed and sprayed on the CMS plants in Brassica Napus.L at the uninucleate stage. The results indicated that mixed spraying the carbamide could improved the chlorophyll content of leaves, the plant height and the daily growth coefficient of plant height; mixed spraying the instant boric fertilizer could increase the number of effective pods of plant, the number of pods and pods density of the main inflorescence and the yield; only the ammonium di-hydrogen potash were mixed with the instant boric fertilizer to spray, the number of the effective pods of plant could be increased ; when the carbamide and the instant boric were mixed to spray , the chlorophyll content of leaves and the yield were increased obviously. It would help to increase the yield and the purity of the hybrid rapeseed seed that the new type chemical hybridizing agents SX-1 and fertilizer were mixed spraying on the CMS in Brassica napus.L in hybrid rapeseed production field.
