种植密度对夏玉米浚单28生长发育及产量的影响
Effects of Planting Density on Growth and Yield of Summer Maize Xundan 28
摘要
Abstract
In order to exert the production potential of summer maize variety Xundan28, and explore its suitable planting density, a field test was conducted to study the effects of planting density on the leaf area index, dry matter accumulation, chlorophyll content, plant lodging resistance and yield of Xundan 28. The results showed that increasing planting density enhanced the leaf area index and dry matter accumulation, decreased the chlorophyll content and plant lodging resistance, and reduced the grains per spike and 1000 -grain weight. In this experiment, the maize yield in the treatment of 60.0 thousand plants per hectare was the highest, and it was 11662.5 kg/hm2. The recommended suitable planting density of Xundan 28 was 60.0 ~ 67.5 thousand plants per hectare in its actual production.关键词
