不同啃食强度对白沙蒿影响的初步研究

A preliminary study on effects of defoliation intensities on Artermisia blepharolepis

根据飞播区牲畜对白沙蒿啃食程度的不同 ,采用人工模拟放牧方法对牲畜啃食的嫩枝及绿色部分设置了 10 %、30 %、50 %、70 %、90 %、对照 6种不同啃食强度的处理 ,探讨啃食强度对白沙蒿生长的影响。试验结果表明 ,白沙蒿放牧利用强度控制在 30 %以下 ,有利于白沙蒿的生长 。

A simulated grazing experiment of six defoliation intensities of 0%, 10%, 30%, 50%, 70% and 90% was conducted in Artermisia blepharolepis aerial sowing region. The results showed that defoliation intensities under 30% benefited the growth of Artermisia blepharolepis and the normal growth of plant was interfered as the defoliation intensities above 30%.
