饲料型四倍体刺槐青贮饲料研究初报

对饲料型四倍体刺槐进行单一青贮和混合青贮试验,从青贮饲料的色泽、气味、质地等感官品质,pH值、氨态氮/总氮比值等发酵品质,以及粗蛋白、中性洗涤纤维和酸性洗涤纤维等营养价值方面进行分析评定.结果表明:饲料型四倍体刺槐地上、地下单一青贮的综合品质一般,两种青贮方式之间无明显差异;而与玉米秸秆混合青贮的综合品质良好,且混合1/3玉米秸秆处理的蛋白含量较高,纤维含量低.

A Preliminary Study on Silage Tetraploid of Robinia pseudoacacia

Experiments were conducted with tetraploid Robinia pseudoacacia for simple and compound silage fermentation.The fermentation quality of the silage was analyzed and appraised by indices of color,odor,texture, pH value,ratio of ammonia-N to total-N,and the nutritional indices including the contents of crude protein,neutral fiber and acid fiber.The results showed that the quality of silage simply made of the tetraploid R.pseudoacacia was poor,and there was no significant difference between the above and under ground fermentation ways.While the integrated quality of silage manufactrued by tetraploid R.pseudoacacia mixed with corn stalks was much better.Silage with higher content of protein and low content of fibers could be obtained when 1/3 of corn stalk was added to tetraploid R.pseudoacacia raw material.
