采用206最优回归设计方案，研究了不同密度和播期对遵糯4号商品穗数的变化规律。结果表明，在试验设置的密度和播期范围内，随着二因素水平的逐渐升高，商品穗数呈现先升后降的变化趋势。综合考虑，密度在49500~55500株/hm2、播期在4月9-15日水平区间内，有利于遵糯4号商品穗数的提高。

With the 206 best regression design of two factors,the influence of density and sowing on commodities spike for the Zunnuo 4 was studied.The results showed that under the test density and sowing,with the two factors increasing,commodities spike increased first and decreased later. Considering that it was beneficial for the commodities spike maize Zunnuo 4,it was suitable for us to select 49 500~55 500 plants/hm2 of planting density and in April 9 to 15 of planting sowing for its commodities spike.
