以壤土、冬小麦秸秆和塑料膜等为材料,在沙质地上进行了毛白杨节水灌溉栽培试验。5a研究结果表明,掺壤土(秸秆)改土、铺塑料膜蓄水等技术措施,均对幼树的成活和生长(胸径、树高、枝条、叶面积)产生了明显的促进作用,掺壤土改土措施的幼树成活率和叶面积分别较对照提高了83%和212%;根据存活、生长及经济效益,提出了适于沙质地节水灌溉栽培的5种栽培模式。
With loam soil, winter wheat straw and plastic film as material, the experiment was conducted on the sandy land with water-saving irrigation. 5a The results showed that the technical measures such as modifying soil with loam soil (straw) and water storage with plastic membrane all promoted the survival and growth of young saplings (DBH, tree height, shoots and leaf area) The survival rate and leaf area of young trees increased by 83% and 212%, respectively, compared with the control. According to the survival, growth and economic benefits, five cultivation modes suitable for water-saving irrigated sandy soil were proposed.
