不同施肥方案对野大麦产草量及营养品质的影响
Acta Agrestia Sinica(2019)
Abstract
野大麦(Hordeum brevisubulatum(Trin.)Link.)是治理东北地区盐碱退化草地的重要牧草,科学合理的施肥能够有效提高牧草的产草量及营养品质.本试验研究了不同施肥时期及施肥量对野大麦干草产量及营养品质的影响.施肥时期分别为返青期,拔节期和抽穗期,施肥量设225,300,375,450,525,600 kg·hm-26个水平,以不施肥做为对照.结果表明:施肥可有效提高野大麦干草产量和营养品质,其中在拔节期,施肥量为525 kg·hm-2时施肥效果最佳,其干草产量达5.93t·hm-2,比对照(不施肥)增加了51.27%;粗蛋白含量为12.98%,比对照增加了92.01%;粗脂肪的含量为3.64%,比对照增加了195.93%.
