| 摘 要： | 在千阳县研究了保水剂对渭北旱原土壤含水量和侧柏幼树生长的影响,研究表明,保水剂以每穴施2.5g最优.在60cm土层内,平均土壤含水量在9.5％以下时,植穴施固体保水剂对林木成活率和生长量不起作用,甚至不利于林木成活与生长.土壤含水量11.5％以上施固体保水剂,其成活率和生长量高于对照,随着土壤含水量增加,施固体保水剂效果越好.

| Abstract: | Effect of water preservation agent on soil water and growth of cypress trees were conducted. The result showed that2.5kg water preservation agent per pit is the optimum amount. Within 60cm layer of soil, when soil water content is below 9.5%, water preservation agent is not effective to im- prove the growth, even negative effect on the growth and survival rate of seedlings. When soil water content is above 11.5%, water preservation agent is much effective in comparison with CK. |
