野生牧草金荞麦与贵州省推广牧草栽培效益比较试验初报

Preliminary study on Comparing the wild forage grass Poyigonum cymosum Trev with extended forage grasses in Guizhou province

金荞麦Poyigonum cymosum是一种药饲兼用的贵州野生植物资源，通过金荞麦与贵州省目前主要推广牧草的田间试验比较，研究金荞麦和推广牧草资源的产量、品质和饲用的不同特点。试验初步认为：金荞麦是一种高产优质的牧草资源，其产量与菊苣Cichorium intybus相似，比一般推广牧草如苜蓿Medicago sntiva等高出2～3倍。其粗蛋白含量与菊苣相似，接近苜蓿。金荞麦的适口性好，耐瘠抗劣性强，易繁殖成活，有较大的推广潜力。

Poyigonurn cyrnosurn Trev is a wild plant in Guizhou and used for herb medicine and forage grass. In a field experiment P. cyrnosurn Trev was planted, and compared with other extended forage grasses on yield, quality and feeding values in Guizhou. This experiment primarily showed that it was a kind of forage grass with high yield and high quality. The yield was as similar as Cichoriurn intybus, and two or three times higher than the other extended varieties in the experiment. Its content of crude protein was also as similar as C. intybus, and a little lower than that of alfalfa. The test showed that it was a good fodder to feeding animals. It had characteristics of strong resistance to poor natural conditions, dry or low soil fertility and easy to reproduce, so it has a great potential for extension.
