刈割对羊茅黑麦草和无芒雀麦蘖转化的影响

Effects of Defoliation on Tiller Turnover in Festulolium and Smooth Bromegrass

根据种群生命统计分析原理，进行了刈割对羊茅黑麦草和无芒雀麦蘖转化的影响的研究，结果表明，羊茅黑麦草比无芒雀麦有较低的蘖死亡率和较高的蘖出现率，在营养期刈割羊茅黑麦草优于繁殖期；应避免频繁强度利用无芒雀麦。

Effects of cutting on tiller turnover in festulolium and smooth bromegrass were studied.The results showed that the rate of tiller death was slower and tiller appearance was quicker in festulolium than those in smoth bromegrass. Cutting of festulolium in vegetation growth stage was better than in reproduction growth stage. Severe frequent cutting of smooth bromegrass sward should be avoided, and defoliation of festulolium sward should be on period of vegetation growth stage.
