不同收获期玉米植株剪切力及其饲料营养特性的研究
SHEARING FORCE AND FEED CHARACTERISTICS OF MAIZE PLANT IN DIFFERENT HARVES PERIODS
摘要
Abstract
The objectives of this study were to investigate the morphological characteristics and nutritional ingredient of maize plant in different harvest periods. The shearing force, linear density and other morphological characteristics of leaf, pericladium and stem of three repeat of maize each of 24 plants were measured, and then chemical compositions were been measured. The results showed that the feed characteristics of maize plant were declined as the experiment extend, while at the milk stage and the dough stage the were better than the physiological maturity stage, and the milk stage is the best.关键词
