| 摘 要： | 在三个不同种植密度下,对不同生育时期的高粱辽杂13的株高、茎粗、叶片数、叶面积指数、叶绿素含量、净光合速率、气孔导度、蒸腾速率和产量等指标数据进行田间测定。结果表明,在种植密度为9.750万株/hm2时,辽杂13的农艺性状和生理指标都比较适宜,籽粒产量也最高。

| Abstract: | At three different planting densities,a set of index numbers of Liaoza 13 such as plant height,stem diameter,the number of leaves,leaf area index（LAI）,SPAD,net photosynthetic rate（Pn）,stomatal conductance（Cond）,transpiration rate（Tr） and yield have been measured in the field.The results show that planting density of 97500 plant /hm2 was appropriate for the growth and yield of Liaoza 13. |
