摘要
对筑糯5号等6个糯玉米品种进行筛选试验,结果表明:鲜果穗产量和经济产值都以筑糯5号最高,其余依次为黔西黄糯、水晶6号、黔西白糯、水晶1号、大方黄糯.选用黔西黄糯进行高产栽培技术试验,设置密度和玉米专用复合肥用量两因素,采用二次回归正交旋转组合设计,得出鲜果穗产量500-600 kg/667m2,平均564.28 kg/667m2的生产方案为:种植密度3 063-3 214株/667 m2,施玉米专用复合肥19.94-25.26 kg作底肥;鲜果穗产量在600 kg/667m2以上,平均618.45 kg/667m2的生产方案为:种植密度3 532-3 712株/667m2,施玉米专用复合肥34.69-37.00 kg作底肥.
Field selection experiment of 6 glutinous maize varieties Zhunuo 5 and so forth was conducted in 2004. The results showed that whether fresh ear output or economic outtput value, Zhunuo 5 was the highest and the others were Qianxi-huangnuo, Suijing 6, Qianxi-beinuo, Shuijing 1 and Dafang-huangnuo in order of yield. Qianxi-huangnuo was used to do cultivation trial for high yield under the design of quadratic orthogonal/rotational regression combination with two factors of planting density and complex fertilizer quantum applied. The results were as follows： 500-600 kg/667m^2 （564.28 kg in average） of fresh ear yield was attained from the cultivation program with 3063 - 3214 plants/667m^2 of planting density and applying 19.94 -25, 26 kg/667m^2 of complex fertilizer as base manure. 618.45 kg/667m^2 of average fresh ear yield was attained from the programe with 3532-3712 plants and 34.69-37 kg of complex fertilizer per 667m^2 used as base manure.
