| 摘 要： | 为解决冬春饲草料不足,充分利用夏收闲田复种饲草料作物,拓宽饲草料来源、提高土壤肥力,对复种初岛燕麦(Avena sativa)和中豌六号豌豆(Pisum sativum)单播及混播的一年生栽培草地进行生物量动态、牧草品质及种间竞争的研究。结果表明,最佳混播组合为初岛燕麦65%(195 kg/hm2)+中豌六号35%(42kg/hm2)和初岛燕麦50%(150 kg/hm2)+中豌六号50%(60 kg/hm2),9月10日刈割干草产量达7 246.44和7 133.91 kg/hm2;粗蛋白产量为624.64和670.6 kg/hm2;最佳刈割期以初岛燕麦开花-灌浆期为宜。初岛燕麦的干物质积累速率高,植株高度占优势,在竞争中一直处于优势地位,其竞争力强于中豌六号豌豆。

| Abstract: | An experiment was conducted to determine the yield and quality of mixed-sowing pasture of Avena sativa and Pisum sativum for increasing the winter forage,making full use of cropland,and improving soil fertility.The results of this study showed that two seeding rates(195 kg/hm2 A.sativa + 42 kg/hm2 P.sativum;150 kg/hm2 A.sativa + 60 kg/hm2 P.sativum) were the best,and their yields were 7 246.44 kg/hm2 and 7 133.91 kg/hm2 on 10 September and their crude protein yields were 624.64 kg/hm2 and 670.6 kg/hm2.The b... |
