种植模式与密度互作对高粱冠层结构及生产潜能的影响
Effects of Planting Pattern and Density Interaction on Canopy Regulation and Production Potential of Sorghum
摘要
Abstract
In order to explore the effects of planting pattern and density interaction on canopy regulation and production potential of sorghum.In this study,the sorghum research institute of Liaoning Academy of Agricul-tural Sciences was used as the material,and two planting modes were set up,including equal row spacing planting and wide and narrow row planting,with four planting densities,including 97500 plants/ha,10500 plants/ha,11250 plants/ha,12000 plants/ha,and the agronomic traits,canopy structure character-istics,dry matter accumulation,yield and yield components were measured and analyzed.The results showed that increasing the planting density increased the grain yield,reduced the grain weight per spike and 1000-grains weight,increased the plant height of sorghum,reduced the stem diameter,panicle length,stem-leaf angle and leaf vertical rate,and compared with the equal row spacing planting,the leaf spatial distribution of the wide and narrow row planting mode was more reasonable,and the dry matter accumulation and yield had obvious advantages.关键词
