为了探明包膜复混肥在油菜方面的应用效果,采用田间小区试验,研究包膜复混肥料对'湘杂油1613'油菜产量、生物量和养分积累的影响.结果表明:包膜复混肥能够提高作物产量和结实率,产量可达到2 342.49 kg/hm2,比对照增产114.79%,比全量普通复混肥处理增产10%;千粒重达到 4.9 g,比对照提高 9.9%;每角果粒数平均16.94个,比对照提高28.9%;包膜复混肥对肥力调节具有显著作用,能够一定程度上调节光合物质的转移方向,有效促进前期根的生长;施用包膜复混肥的氮、磷、钾利用率分别达45.04%、17.38%、72.20%,比普通复混肥处理分别提高了11.98%,26.02%,25.52%.

A field plot experiment was carried out to test impacts of coated compound fertilizer on the yield, biomass and nutrient accumulation of rape, which is named by ＇Xiangzayou 1613＇. The results suggested that： coated compound fertilizer could increase rape yields, improve its quality and ripening rate. The yield could reach 2 342.49 kg/hm^2, which increased by 114.79% compared with that of CK and 10% with that of ordinary urea fertilizer. The thousand grain weight reached 4.9 g, which is higher 9.9% than that of CK. The average number of pod g...
