野生与栽培型沙打旺品质性状比较

Comparison Study on Several Quality Characters of Wild and Cultivated Astragalus adsurgens Pall.

山西五台山野生沙打旺的消化率、粗蛋白质、中性洗涤纤维 ,酸性洗涤纤维和酸性洗涤木质素等品质均优于栽培型沙打旺。叶茎比在营养期低于栽培型 ,现蕾期后则高于栽培型。现蕾期是营养品质参数出现明显变化的转折点。

The digestibility、CP、NDF、ADF and ADL quality characters of the wild A.adsurgens Pall.of Shan Xi Wu Tai Mountain are better than the quality characters of the cultivated A.adsurgens Pall.,only leaf stem ratio is lower than the one of the cultivated A.adsurgens Pall.at the period of vegetative growth,but leaf stem ratio is higher than the cultvated one after squaring stage,squaring stage is a turning point that most of the nutritive quality parameters varied evidently.There is a possibility to improve the nutritive quality of the cultivated A.adsurgens Pall by cross breeding between the wild and the cultivated A.adsurgens Pall.
