摘　　要：果园生草栽培适宜的播期可以错开草种和果树的旺盛生长期,达到优势互补,以最少的投入获得最大的收益。在前期桃园生草栽培草种筛选的基础上,以秋冬季冷季性草种大麦草为试验材料,通过对大麦草不同播期的高度、覆盖度、生物量、营养元素等进行测定,探讨了武汉地区桃园秋冬季间作大麦草的适宜播种期。结果表明,10月中旬播种的生长高度和所产鲜草量最高,9月下旬播种的覆盖度最高,生长高度和产鲜草量也较高,11月份播种的最低;从不同时期播种及不同刈割期对干草所含营养成分的分析来看,10月中旬播种,春前刈割和4月上旬大麦抽穗前刈割,植株所含全氮、全磷、全钾较高。因此确定9月下旬到10月中旬是武汉地区桃园种大麦草的最佳播种期。The suitable seeding time of orchard grass planting can stagger the grass and trees exuberant growth period,achieve complementary advantages,with minimal input to obtain the biggest benefit. Based on the early stage of the peach orchards grassing grass seed selection,the barely straw in autumn-winter cold season was selected as experimental material,the seeding time,height,coverage,biomass of different seeding date were study,such as nutrient elements were determined. The adapted seeding time of peach orchard intercropping barely straw in the Autumn-winter period was studied. The results showed as follow: the growth height and produced amount of grass is highest in the Mid-october seeding,the coverage is highest in late September seeding,growth height and grass production is higher also,the lowest in November. As to the hay contains nutrients of different periods and different mowing period,the mid-october seeding,mowing time before spring and early April,the total of N,P and K was most high. Therefore,the results determined that late September to the middle of October was the best seeding time about barely straw seeding time of peach orchard in Wuhan area.
