牧草作物金荞麦的引种比较试验

A Introduction Test of Poyigonum cymosum,a Local Forage Crop

金荞麦是一种投资少、见效快、种源方便、易栽易活的多年生野生饲料作物。2004～2005年，通过引种金荞麦与当前推广的牧草品种进行比较试验，结果表明，2004年金荞麦产量6617．2kg／667m^2，名列第二．菊苣7056．3kg／667m^2（名列第一），方差分析其间无显著差异；2005年金荞麦产量6703．7kg／667m^2，名列第二，菊苣6731．5kg／667m^2（名列第一），两者之间没有差异。两年试验表明，金荞麦的产量、营养价值与适口性均优于其它参试牧草品种。

Poyigonum cymosum is a wild perennial forage crop with advantages of easy transplanting and survival, fast growing and abundant seedling resource. The results from the comparative trails between Poyigonum cymosum and other popularized forage crops show that the fresh grass yield of Poyigonum cymosum is up to 6617.2 kg/667m^2 and 6703.7 kg/ 667m^2 , which is close to 7056.3 kg/667m^2 and 6731.5 kg/667m^2 of the highest yield of Cichorium intybus in 2004 and 2005 respectively and there is no significant difference between the fresh grass yields of Poyigonum cymosum and Cichorium intybus. The yield, nutrient value and palatability of Poyigonum cymosum are better than other tested forage crops.
