摘要
设置7个不同种植密度研究其对晚播齐黄34株高、主茎节数、茎粗、有效分枝数、株粒数、百粒重等主要农艺性状及产量的影响。结果表明,随着密度增加,株高及百粒重逐渐增加,主茎节数、茎粗、有效分枝数及单株粒数降低,单位面积产量呈现先上升后下降趋势,最佳种植密度为25.5万株/hm2。
In this paper,7 planting densities were designed to study their effects on the plant height, main stem node number,average stem diameter,number of effective branches,grains per plant,100 -grain weight and yield of Qihuang 34 under the late sowing condition.The results showed that with the increase of planting density,the plant height and 100 -grain weight increased gradually,the node number of main stem, stem diameter,number of effective branches and grains per plant decreased,the yield increased firstly and then decreased.The optimum planting density was 255 thousand plants per hectare for Qihuang 34.
