紫花苜蓿与鸭茅混播效应初探
Mixed Sowing Effects of Alfalfa and Orchard Grass on Forage Yield ani Interspecific Competition
摘要
Abstract
[ Objective ] To explore the mixed sowing effects and optima] mixed ratio of affalfa and orchard grass. [ Method ] The alfalfa and orchard grass were sowed at different ratios ( 1∶0,3∶1,1∶1,1∶3 and 0∶1 ). They were grouped and named as CKI ,A1 ,A2,A3 and CK2,respectively.The forage yield,relative yield total (RYT) and the competition rate of alfalfa and orchard grass、in each group were determined,respectively.[ Result ] In the A3 treatment group,the total forage yield was the highest (4 827.67 kg/hm2) and significantly different from that of other treatment groups ( Ρ ＜ 0.01 ). In every mixed treatment group, the RYT was higher than I, and the allalfa was more competitive than the orchard grass in the mixed-seeding grassland. [ Conclusion] Our studies may provide a basis for the establishment of artificial mixed-seeding grassland which has high yield and quality.关键词
