摘要 为了筛选出适宜麦后复种的优质牧草,试验采用优质牧草及小杂粮作为饲草进行麦后复种,通过对复种牧草的物候期、生长发育速度、株高、产量、营养成分等因素的测定对比分析,初步结果表明:适宜麦后复种的牧草有燕麦、湖南稷子、朝牧一号稗子、张杂谷3号、糜子、籽粒苋等,可以充分利用夏秋季光照充足、温度高、降雨丰富的气候优势进行快速生长,营养物质也能迅速积累,从而达到较高的产量。综合分析认为利用麦后空闲耕地种植品质优、产量高的牧草,是一举兼得、经济实惠的耕作模式,值得推广。 In order to select high-quality forage suitable for cropping after wheat, a test was carried out with high-quality forage and coarse cereals cropping after wheat as forage grass and an identification and comparative analysis was made on their phenological period, growth rate, plant height, output and nutrient content. The results showed that the forage species suitable for cropping after wheat include wheat oats, Hunan millet, barnyard grass Chaomu No.l, millet Zhangza No.3, broom corn millet and grain amaranth. These species grow and accumulate nutrition fast under ample sunlight and rainfall and thus result to high yield. It was concluded that growing high-quality and high-yield forage after wheat could achieve many things at one stroke and worth promoting.
