摘要
饲用玉米—黑麦草种植模式是南方草地农业系统的组成部分。在此系统中采用优良的多花黑麦草品种,适宜的种植密度或播种量,适时的刈割时间和科学的栽培技术,能获得8419.5～12372kg/hm2的饲料干物质产量。通过不同时期多花黑麦草营养成分动态变化情况,为适时刈割利用提供了依据。同时还对饲用玉米与黑麦草的时空配置、营养价值和生产成本进行了分析和评价。
Planting model of'Corn-Italian Ryegrass'was a part of composition of southern grassland agricultural system.In this system,DM yield of feeds may get to8419.5～12372kg /hm 2 ,on the conditions of excellent Italian Ryegrass,appropriate density of planting or weight of sowing,appropriate cutting time and scientific planting tech-niques.According to the variability of nutritive components of Italian Ryegrass in different seasons,appropriate har-vesting time and could be decided,the same to what time to be utilization.Whilst analyses and evaluations were de-veloped,including time manipulation,nutritive value and production cost of zea mays L and Italian ryegrass.
