摘要
通过地膜覆盖育苗对比试验,得出了地膜覆盖对土壤的增温作用,对土壤的保水作用,以及提高了苗木高径和根系生长量。克服了德令哈地区干旱、缺水、低温等不利育苗因素,是值得推广的先进育苗方法。
The results from comparative experiment of seedlings covered with film indicated that, temperature -increasing effect of film cover on soil, the role of water conservation on soil, seedling height - diameter and root growth was improved, the paper overcomed some unfavorable factors which it consisted of drought, water shortage and low - temperature in the region of Delingha, this is a advanced method to spread for seedling cultivation.
