摘要
通过试验 ,验证绿源生物有机肥对旱地玉米的增产效应。生物有机肥比单质氮磷钾化肥玉米每 6 6 7平方米增产 5 1 3公斤 ,增产率 14 17% ,增产效果及经济效益显著。
Through experiments the output increase effect of organism organic fertilizer of green resources on dry land corn could be verified.Applying organism organic fertilizer, the output of corn increased by 51.3kg/667m 2, i.e.14.17% comparing that of applying the chemical fertilizer of elemental N, P, K. Thus the output increasing effect and economical benefit were obvious.
