| 摘 要： | 抑制玉米鲁单50的生殖生长后，玉米茎鞘和叶片的粗蛋白、粗脂肪和无氮浸出物的含量显著地高于对照，粗纤维、木质素和粗灰分的含量显著地低于对照；但是由于抑制生殖生长后籽粒不能发育形成，在生育后期玉米全株的饲用营养价值低于对照。结果表明，抑制玉米的生殖生长可显著地改善茎鞘和叶片的饲用营养品质，有利于提高乳熟末蜡熟初期收获用作育饲育贮玉米的饲用营养价值。

| Abstract: | After restraining genital growth(RGG),contents of crude protein, ether extract and nitrogen-free extract of corn stalks and leaves were significant higher than CK. On the other hand,contents of crude fiber, lignin, ashes were significant lower than CK.Because corn grains couldn't develop after restraining genital growth, forage nutritive value of whole plant corn was lower than CK at the late development stage of corn. So restraining genital growth could be used to improve the forage nutritive value of forage and silage corn varieties. |
