摘　　要：针对不同类型饲用玉米在N肥用量一定的情况下,我们通过不同时期和不同的施肥比例试验发现:拔节期和大喇叭口期增加氮肥的施用比例有利于饲用玉米的干物质积累和产量形成。且不同类型玉米施氮的侧重时期不同,青贮型玉米侧重于大喇叭口期,粮饲兼用型玉米侧重于拔节期。In a number of nitrogen way, through the test of different fertilization in different stages about different feeding maize, we found that increasing fertilization scale of nitrogen was good at dry matter accumulation and yield formed of feeding maize. Just, different type feeding maize emphasized particularly on different stages of nitrogen fertilization. Silage maize emphasized particularly on stage of big bugle, but grain and feeding compatible maize emphasized on stage of elongation.
