| 摘 要： | 新疆自1979年在小麦收获后复种向日葵做绿肥成功以来,目前每年播种40～50万亩,约可产茎叶2亿公斤。它不仅是好的绿肥资源,而且是可贵的青绿饲料资源,而且做饲料时的生态效益和经济效益更好。 盛花期的复种向日葵茎叶青贮,半干样中含粗蛋白11.65％,粗纤维19.7％,适口性好;它也是晚秋季节很好的青绿饲料,半干样中含粗蛋白11.05％,粗纤维19.1％,饲喂奶牛可提高产奶量10～13％。

| Abstract: | Since the sunflower used as green manure was sowed successfully after harvesting wheat in Xinjiang in 1979, now it has been sowed 400-500 thousand mu every year, producing stems and leaves about 200 million kilogram. It is not only good green manure resorces, but also valuable greenfeed resources, and will have a very good ecologic and economic effect when used as feed.
When the stems and leaves of multiple cropping sunflower are ensiled in the period of full bloom, the half dry matter of the ensilage contains CP 11. 65% , CF 19. 7%. The ensilage is pala -table. The multiple cropping sunflower is also a very good greenfeed in late autumn. The half dry matter of it contains CP11. 05% , CF 19. 1%. Feeding cow with it can raise the output of milk 10-13%. |
