摘要
为了确定牧草的适宜利用时期,按生育期测定了红豆草和抗早苜蓿的产量和营养成分,结果证明牧草随生育期产量增加,粗蛋白含量减少,粗纤维含量猛增,根据纤维蛋白比结合产量确定牧草的利用时期,两种豆科牧草在盛花期刈割,可获得较高的经济效益。
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 ithheproductions, 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.
