摘　　要：盆栽试验结果表明 ,结晶有机肥比尿素增产 2 0 86% ,达 1%显著水准 ;与普通复合肥处理产量无显著差异。结晶有机肥利于菜籽中蛋白质和脂肪的积累 ,与尿素、普通复肥比 ,结晶有机肥增加脂肪含量分别为 14 48%、13 2 5% ,增加蛋白质含量分别为 11 16%、14 0 5%均达到 5%显著水准。结晶有机肥和尿素两处理的菜籽中芥酸、硫甙含量比普通复肥处理显著增加。苹果酸处理抑制了分枝数、角果数、千粒重的提高 ,因而产量最低 。The results of pot experiment showed that crystal organic fertilizer increased yield of rape by 20.86% compared with urea. But,there was no noticeable yield difference between crystal organic fertilizer and compound fertilizer treatments. Crystal organic fertilizer increased the content of oil and protein in rape seed compared with urea and compound fertilizer,by 14.48%,13.25% and by 11.16%, 14.05% respectively. Crystal organic fertilizer and urea treatment could significantly increase the content of eruciea acid and glucosinolate compared with compound fertilizer. On the other hand, the treatment of malic acid inhibited early growth of rape and the content of oil in rape seed was lowered by fertilizing nitrogen at later stage.
