摘    要:目的]探讨不同刈割处理对稻草轮作黑麦草干物质产量和体外消化量的影响。方法]以黑麦草为材料,采用二因素四水平研究稻草轮作模式下不同刈割处理对黑麦草干物质产量和体外消化量的影响。结果]在4个水平留茬高度下,40cm高度刈割黑麦草千物质产量最高,达5357.50kg/hm^2;在40cm高度刈割下,留萑高度为6cm的刈割处理黑麦草的千物质产量最大,达1562.50kg/hm^2;40cm高度下刈割并留茬6cm处理下的黑麦草干物质体外消化量最大,为1064.68kg/hm^2。结论]在黑麦草高度为30~40cm且留茬高度为6cm左右时刈割,能取得最高的干物质产量和体外干物质消化量。

关 键 词:黑麦草  IRR系统  干物质产量  体外干物质消化量
