密度和播期对玉米新品种"中地175"农艺性状和产量的影响
Effects of Planting Density and Sowing Date on Agronomic Characters and Yield of New Maize Variety Zhongdi 175
摘要
Abstract
The effects of different sowing dates (April 16th～ May 26th)and different planting densities (45000～67500 plant/hm2 )on the main agronomic characters and yield of new maize variety"Zhongdi 175"were studied through adopting two-factor split plot design. The results indicated that:both the leaf area index and the yield of maize increased with the increase in planting density within the experimental density scope;when the sowing date was May 6th,the leaf chlorophyll content of maize was the highest,and the yield of maize was also the highest (9023 kg/hm2 ). Thus,the optimum sowing date of Zhongdi 175 was May 6th,and its optimum planting density was 67500 plant/hm2 .关键词
