摘要
通过对饲用型玉米陕单8806进行37500、48000、58500和69000株/hm2等4个密度试验,结果表明:陕单8806的适宜栽培密度为63000株/hm2左右,其吐丝期的合理叶面积指数为5.8左右,该密度下陕单8806拔节至成熟的物质净同化率可达14.3g/(d·m2)左右。
Through setting four density of 37500, 48000, 58500 and 69000 plants/hm2 in feeding maize shaandan 8806, it is founded that the feasible planting density of shaandan 8806 is 63000 plants/hm2. The reasonable leaf area index is about 5.6 during spin stage. Under the density, the Net assimilation rate can reached 14.3 g/(d.m2) during jointing to mature.
