Evaluation on the Production Performance of Tianzhu Astragalus adsurgens in Alpine Region
摘要
Abstract
Tianzhu Astragalus adsurgens is a cold adaptive leguminous pasture bred in alpine regions.This experiment was carried out to evaluate the cold resistance,growth and performance of Tianzhu Astragalus adsurgens,Astragalus adsurgens and Longdong alfalfa.The results showed that Tianzhu Astragalus adsurgens had a good adaptability to alpine climate conditions.The winter survival rate,herbage growth,yield and nutrient contents of Tianzhu Astragalus adsurgens at flowering stage were higher than those ofAstragalus adsurgens at the altitude of 2 500-2 700 m a.s.1.at Minxian,and Tianzhu Astragalus adsurgens could complete the growth period and the mature seed could be harvested.The growth period of Longdong alfalfa could not be completed and the winter survival rate and performance were low,which could not adapt to alpine climate condition.关键词
