| 摘 要： | 研究了不同刈割间隔时间对苜蓿产草量、品质及越冬率的影响。结果表明:刈割间隔时间对苜蓿产草量、品质及越冬率有极显著影响(P<0.01)。随刈割间隔时间增大,苜蓿产草量增加;粗蛋白含量显著下降(P<0.05),粗纤维、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)含量显著(P<0.05)上升,导致干草品质下降;其中以间隔25 d越冬率最低,仅为83.33%,极显著(P<0.01)低于其它处理。综合考虑,试验地区及同类生态地区间隔35 d刈割可获得高产草量、高品质的苜蓿干草,而且越冬率高。

| Abstract: | An experiment was conducted in Cangzhou during 2004-2005 to study the effect of cutting alternation on Alfalfa forage yield,quality and over-wintering rate.The study showed that the effect of cutting alternation on the alfalfa forage yield,quality and over-wintering rate was significant(P<0.01).With the adding of the cutting alternation,the forage yield was increased observably(P<0.05).The content of CP was decreased,but the content of CF,ADF,NDF were increased.This resulted bad quality.The over-wintering rate of the group(25 d) was 83.33%.It was lower significantly(P<0.01) than other groups.The results showed that the group(35 d) was the best cutting alternation in the experiment area. |
