Effects of Planting Density on Agronomic Characters and Yield of Summer Foxtail Millet
摘要
Abstract
[Objective]Effects of different planting density on agronomic characters and yield of summer foxtail millet were studied.[Method] Jinxuan 6 was used as material.Six density (30×104 ,60×104,90×104,120×104,150×104,180×104 plants /hm2) were set by randomized block design to explore agronimic characters,economic characters,and lodging resistance of Jinxuan 6.[Result]The plant height,stem diameter,stem dry weight,spike length,spike diameter,plant dry weight,spike weight,grains weight per spike,percentage of grain weight and thousand grain weight decreased gradually with the increase of density.And the difference between treatments was significant.The yield of foxtail millet increased first and then decreased with the increase of density.The yield reached to maximum 6 038.01 kg/hm2 when the density was 90×104plants/hm2 ,while the density 60×104 plants/hm2 next.And the difference between the two was not significant.By curvilinear regression analysis with SPSS,the quadratic curve model Y=4 762.081+27.812x-0.161x2 was the suitable model to describe the relationship between planting density and yield.When the density was 86×104plants/hm2 the yield reached to maximum 5 963.16 kg/hm2.The suitable theoretical density was basically consistent with the actual one.[Conclusion]The suitable planting density of Jinxuan 6 was 60×104plants/hm2 to 90×104plants/hm2.关键词
