| 摘 要： | 试验于2001～2002年对三个不同类型5个玉米品种饲用栽培的营养品质进行了系统研究.结果表明不同类型玉米品种各器官营养成分含量不同,营养成分在各器官中的分配也不相同,植株干物质各营养成分含量也因品种而异.就营养成分含量而言,粗蛋白含量科多8号最高,而科青1号最低,中单9409、东陵白及掖单13居中;粗脂肪含量粮饲兼用型玉米品种较高,普通型玉米品种其次,二者均高于青贮专用型;粗纤维含量青贮专用型玉米品种较高,粮饲兼用型玉米品种居中,普通型玉米品种最低;无氮浸出物的含量普通型玉米品种＞粮饲兼用型玉米品种＞青贮专用型玉米品种;粗灰分含量青贮专用型玉米品种大于普通型玉米品种与粮饲兼用型玉米品种.由于干物质中营养成分含量的不同及干物质积累量的不同,营养成分积累量不同类型品种间也存在一定的差异性.

| Abstract: | This experiment explored silage matter and its nutritive quality of five varieties of three types maize from2001to2002.The main results were as follows:Nutrients content of every organ and whole plant crop(WPC)of different types maize were different,the same as the nutrients distribution in organs.Representation of WPC nutri-ents content:content of crude protein was KD8>ZD9409>DLB>YD13>KQ in9/20;other extract content of maize as foodstuff and silage was the highest,followed by general maize and special silage maize;crude fiber content of special silage maize was higher than that of maize as foodstuff and silage,general maize' was the lowest;content of nitrogen free extract of different types maize was opposite to the crude fiber content;ash content was special silage types maize>general type maize and foodstuff and silage maize.Nutrient accumulations of different types maize were different because of the differences of nutrients content and dry matter accumulations. |
