摘要
美国籽粒苋是一种高蛋白多用途饲料作物,根据我们的栽培试验表明,美国籽粒觅植株高达3.4m,亩产鲜草0.74万公斤。亩产籽种588公斤。美国籽粒觅花期营养价值最高,粗蛋白含量17.5％。粗纤维16.71％,比其它牧草都低。通过奶牛饲喂试验,试验组比对照组,奶牛日均增奶无显著差异。由于美国籽粒觅生长期短,在水肥条件好的情况下,能获得高产,因此适宜在甘肃河西三地区武威、张掖、酒泉和一些灌溉条件较好的川水地带大面积推广种植,特别是在小麦收割前后,进行套种、复种,效益更好。
ABSTRACT In order to determine the proper cutting period, production and nutritive value were meas-ured in Onbrychi viciaefolia and Medicago sativa according to their phenological development.The results showed that production increased, crude protein content decreased and crude fiber content increased drastically as development progressed. Based on the ratios of crudefiber to crude protein and combined with the productions, the proper cutting periods can be detemined. It is suggested that higher economic benefit can be obtained if the two legumes are cut at full blooming stage.
