[目的]探求油菜优质高产栽培途径。[方法]采用土培试验,在油菜盛花期对其茎叶喷施质量分数为1.00%的KCl溶液和质量分数为1.17%的K2SO4溶液和清水,于角果初期和收获期采样,测定油菜光和产物、可溶性糖和游离氨基酸含量。[结果]与对照相比,喷施1.00%KCl溶液能提高了角果初期功能叶叶绿素a含量和叶、茎及花果可溶性糖和游离氨基酸含量,并降低了收获期叶茎可溶性糖、游离氨基酸含量,使籽粒产量平均增重10.20%,籽粒油分、油酸和亚油酸含量分别平均提高了4.40%、10.60%、11.40%,蛋白质、芥酸和硫甙含量分别平均降低了5.10%、9.70%、3.70%。喷施K2SO4与对照间差异不显著,与喷施KCl间差异显著。[结论]该...

[Objective] In order to seek the way of high quality and high yield of oilseed rape.[Method] Soil culture experiment was used in this research.1% （mass fraction） KCl solution was sprayed to the stems and leaves of oilseed rape in full blooming stage while 1.17% （mass fraction） K2SO4 solution and clear water were used for comparison,sampling in initial silique stage and harvest stage were conducted to detect photosynthate,soluble sugar and free amino acids content.[Result] The results showed that compared with spraying clear water,spraying K...
