摘要
同时混播和不同时混播条件下牧草种子萌发的化感作用有不同的表现。同时混播中的不同处理对混播牧草种子萌发率没有显著影响,不同混播条件下不同科牧草之间具有良好的混作效应,豆科的白三叶和禾本科的黑麦草之间表现出明显的促进作用,同科牧草之间表现出抑制作用,紫花苜蓿先播抑制作用最明显。在萌发时产生的分泌物能够显著地抑制其自身和其它植物的生长,表现出强烈的自毒化感潜势。
This paper discusses that the allelopathic potential effect of pasture species has different performance under the conditions of mixed spawning simultaneously and asymptotically.No significant effect appeared in the pasture seeds germination rate processed differently of simultaneous mixed spawning;good effect appeared in the different families of pasture at the condition of asymptotical mixed spawning.
