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

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.
