黄土高原坡地枣树地膜微集水造林效果研究

在黄土高原丘陵沟壑区,采用田间试验研究了地膜微集水造林技术对提高枣树成活率、土壤温度以及枣树根区土壤水分含量的影响。结果表明:地膜微集水方法提高枣树移栽期0~100cm土层土壤水分,提高0~20 cm土层地温,造林成活率较对照提高15%;在枣树生长期和发芽期,土壤0~100 cm剖面含水量比对照高30.3%;在集中降雨后48 h内,土壤水分下渗深度比对照深34 cm,达到67 cm。该方法成本低、操作简单、效率高,可以在黄土高原枣树栽植中推广应用。

The effect of plastics mulching on water micro catchments for jujube plantations and soil moisture content were studded on Loess Plateau using of field trials in hilly and gully region of loess plateau.The results showed that the technique can increase the soil moisture in 0~100 cm depth,and increase soil temperature in 0~20 cm and survival rate of jujube trees.The survival rate increased by 15%,the soil moisture with the treatment increased by 30.3% compared with the control under 0~100 cm in the transplan...
