摘要
考察了不同用量的荣宝及大荣土壤修复剂在油菜(Brassica napus L.)上的应用效果。结果表明,施用荣宝及大荣土壤修复剂的油菜比对照增产8.99%~25.86%,其中荣宝施用量为20 kg/667 m2时,对油菜增产及菌核病抑制效果最为明显。同时施用一定量的荣宝及大荣土壤修复剂可以增加油菜子含油量和粗蛋白质含量,并对土壤p H有一定的调节作用。
Application effects of Rongbao and Darong soil restoration agent with different dosage on rape（Brassica napus L.）were tested. The results showed that Rongbao and Darong soil restoration agent could increase the yield of rape by 8.99% to25.91%. When the dosage of Rongbao was 20 kg/667 m2,the rape yield was the highest and sclerotium disease suppression effect was the best. Furthermore,suitable dosage of Rongbao and Darong soil restoration agent could increase the crude protein content and oil content in rapeseed at as well as the p H of the soil could be adjusted.
