试验选取5种土内加物(锯末、珍珠岩、厩肥、保水剂、容器袋)的土壤保墒措施,探讨抗旱造林的土壤保墒技术对土壤水分、养分及容重的影响,以及各处理对林木成活及生长状况的影响。结果显示:不同保墒措施改善了土壤理化性质,促进了林木成活及生长,其中添加厩肥造林成活率最高,其次添加保水剂、锯末。添加保水剂措施促进林木生长最大,其次添加厩肥、添加容器袋。选取造林成活率提高率、年均高生长提高率、造林成本增加率,采用隶属函数值法对各处理进行了评价,结果添加容器袋措施最好,依次添加厩肥、添加保水剂、添加锯末、添加珍珠岩。
The soil moisture conservation measures of 5 kinds of soil additives (sawdust, perlite, manure, water retention agent and container bag) were selected to study the effects of soil moisture conservation techniques on soil moisture, nutrients and bulk density, and the survival of forest trees And the impact of growth status. The results showed that different measures of soil moisture conservation improved the soil physical and chemical properties, promoted the survival and growth of trees, of which the added survival rate of manure afforestation had the highest survival rate, followed by addition of water-retaining agent and sawdust. Add water retention agent to promote the maximum growth of trees, followed by adding manure, add container bags. Select the afforestation survival rate to improve the rate of increase in average annual growth rate of afforestation, afforestation cost increase rate, membership function value method to evaluate the treatment, the results of the best measures to add container bags, followed by adding manure, add water retaining agent, add sawdust, Add perlite.
