摘要
以石子、芦苇、玉米秸秆和地膜4种材料进行土壤隔盐处理,研究隔离层对冬枣生长的影响结果表明,4种隔盐材料均可降低土壤盐度,可有效促进冬枣的生长,其中芦苇的阻盐效果最好,冬枣的新生枣头生长量、新生二次枝数量、新生二次枝生长量以及新生叶片数量和根径生长量均为最大,尤其是新生枣头生长量和根径生长量,与其他几个处理的差异均达到了极显著水平,且在后期的生长过程中生长势最为旺盛;石子和玉米秸秆隔离层的阻盐效果次之,两者间无明显差异,地膜隔离层效果最差。
The soil was isolated with stone,reed,corn straw and plastic film to study the effect of isolation layer on the growth of winter jujube,the results showed that the four kinds of salt isolation materials could reduce soil salinity and effectively promote the growth of winter jujube.Among them,reed had the best salt barrier effect,the growth of new jujube head,the number of new secondary branches,the growth of new secondary branches,the number of new leaves and the growth of root diameter of jujube were the largest.In particular,the growth of new jujube head and root diameter had reached a very significant level compared with other treatments,and the growth momentum was the most vigorous in the later growth process.The salt isolation effect of stone and corn straw barrier layer was the second,there was no significant difference between them,and the effect of plastic film barrier layer was the worst.
