水泥硬壳覆盖条件下水热盐运移及其对枣树生长的影响

Effects of concrete mulching on the movement of soil water,salt,and heat as well as growth of jujube

摘要: 通过对水泥硬壳覆盖条件下水热盐运移及其对枣树生长发育和根分布的影响研究发现，水泥硬壳覆盖可抑制土壤水分蒸发，提高土壤最低温度，降低土壤最高温度，使表层土壤脱盐率达22.2%。水泥硬壳覆盖条件下水热盐运移有利于枣树生长，可提高枣产量31.7%，使枣树根表聚。

Abstract: The field experiment was conducted to clarify the effects of concrete mulching on the movement of water,salt and heat as well as the growth and development of jujube trees.The results showed that both the content of soil water and jujube yield were remarkably increased under the situation of concrete mulching.Meanwhile soil evaporation and the amplitude of water content variations were reduced,and salt movement up to the surface soil was effectively controlled.
