混播草种及其比例对黔草4号鸭茅草地产量的影响
Effects of Different Mixed Seeding Grasses and Their Proportions on the Yield of Qiancao 4 Grassland
摘要
Abstract
[Objective] To discuss the mixed sowing grass combination and grassland yield for Qiancao 4 Dactylis glomerato CV.Barula.[Method] With single sowing of Qiancao 4 as the control,we established nine mixed seeding grass treatments in Gonghe Village,Dejiang County,Guizhou Province,including different proportions of D.glomerato(Qiancao 4)+Trifolium repens+Lolium perenne,D.glomerato+T.repens+Festuca elata,D.glomerato+T.repens.Effects of different treatments on grass height,yield,legume-grass ratio and leaf-stem ratio were researched.[Result] D.glomerato+ T.repens +L.perenne (2:1:1) showed the highest yield (101 610 kg/hm2),which was extremely significantly higher than other treatments.Its leaf-stem ratio was 2.98 with high quality of grassland.This treatment was the optimal grass combination and mixed sowing proportion.[Conclusion] This research provides references for the screening of the optimal grass combination and mixed sowing proportion of Qiancao 4 in Guizhou Province.关键词
