生物炭包衣对沙打旺抗旱性的影响
The Effect of Biochar Coating on the Drought Resistance of Astragalus adsurgens
摘要
Abstract
To investigate the effect of biochar coating on the drought resistance of Astragalus adsurgens,this experiment established four sand bed moisture levels(2%,3%,5%,and 10%,with 10%as control)and four biochar coating mass ratios(biochar∶seed at 1∶15,1∶10,1∶5,and 1∶3).Germination tests conducted in the sand beds were aimed to identify apporiate drought stress simulation conditions and to determine the optimal biochar coating formulation.Effects of biochar coating on seedling emergence,seedling growth,and antioxidant enzyme activities under drought stress were also assessed.The results indicated showed that,under 2%sand bed moisture condition,which simulated drought conditions,the biochar coating treatment with at a 1∶10 mass ratio(biochar∶seed,denoted as BC1-10)significantly increased(P<0.05)seedling emergence rate,fresh weight,root length,seedling length,and antioxidant enzyme activities.关键词
