摘要
通过对甘南县兴久村的不同树种施用不同梯度保水剂的试验研究,结果表明:不同梯度保水剂对提高苗木的成活率和保存率起到一定的作用,呈现一定的线性规律,对促进苗木高生长和径生长都起到明显作用。
Experiments of water retaining agent with different gradient on different tree species were conducted in Xingjiu village of Gannan County. The results show that water retaining agent with different gradient has some effect in increasing survival ratio and preserving ratio of seedlings . It appears certain Linear Law and can accelerate the height growth and diameter growth obviously.
