[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KC l溶液、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,测定油菜光合产物、可溶性糖含量和游离氨基酸含量。[结果]与对照相比,喷施1.00%KC l溶液提高了角果初期功能叶叶绿素a含量,叶、茎及花果可溶性糖含量和游离氨基酸含量,并降低了收获期叶、茎可溶性糖和游离氨基酸含量,使籽粒产量平均增加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、芥酸和硫苷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KC l间差异显著...

[Objective]In order to seek the way of high quality and high yield of oilseed rape.[Method]The soil culture used in this experiment.1%（mass fraction） KCl solution and 1.17%（mass fraction）K2SO4 solution were sprayed to the stems and leaves of oilseed rape in full blooming stage while while 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.soil culture used in this experiment.[Result]The results showed that compared with sp...
