摘要
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号鲜穗数的影响。结果表明：在试验设置的密度和播期范围内,随二因素升高,鲜穗数先升后降。综合考虑,密度在55 500~64 500株/hm2、播期在4月12—18日水平区间内,有利于遵糯4号鲜穗数的提高。
With the best regression design of two factors, the influences of density and sowing date on fresh spike in the Zunnuo 4 were studied. The results showed that under the test density and sowing date,with the two factors increasing,fresh spike increased first and decreased later, considering that it was beneficial for the spike of fresh maize Zunnuo 4,it was suitable for us to select 55 500-64 500 plants per hectare of planting density and in April 12 to April 18 of planting sowing for its fresh spike.
