Effects of Mixed Sowing Ratio of Bothrichloa ischaemum and Lespedeza davurica on Forage Production Performance and Quality
摘要
Abstract
To explore the effects of the optimal mixed sowing ratio of native grass species on the production performance and quality of forage,in this study,Bothrichloa ischaemum cv.Taihang and Lespedeza davurica cv.Jinnong 1 were selected as test materials.7 treatments according to the 1∶1,1∶2,1∶3,1∶4,2∶1,3∶1,and 4∶1 ratio of B.ischaemum to L.davurica were set.Two unicast treatment(Tck,Jck)were set as the control,a randomized block design was used,and the production performance and quality indexes including plant height,yield,leaf-stem ratio,and crude protein content were determined.The results showed that the growth rate of B.ischaemum ranged from 0.14-0.48 cm/d from May to early June,with the highest ratio of 1∶1 and the lowest Tck.By early July,the growth rate of B.Ischaemum increased significantly,with the fastest growth rate of 1∶4 and the slowest growth rate of 2∶1,and the overall growth rate ranged from 0.31 to 1.88 cm/d.The growth rate of L.davurica ranged from 0.58 cm/d to 1.55 cm/d.The hay yield of mixed sowing was the highest at 1∶4(15.21 t/ha)and 1∶3(15.77 t/ha),which was significantly higher than that of the control.Mixed sowing increased the content of crude protein.In the mixed sowing combination,the combinations of 1∶3 and 1∶4 had the highest plant height,hay yield,and crude protein content,mixed sowing of the two kinds of grass had good compatibility and improved the production performance and quality of forage.关键词
