| 摘 要： | 通过在张掖市林果业研究所苹果梨园内进行的果园覆草节水效果的研究,结果表明:果园覆草具有明显的保水作用。0～60cm土层的土壤含水量显著高于清耕对照;不同深度土层以0～20cm土层含水量最高,为10.4%,说明覆草能抑制表面蒸发;覆草能促进苹果梨树体生长,明显提高果实品质,使大果率增加25%,平均单果重增加12.1%。

| Abstract: | The study of water-saving effects in orchard covering with grass was carried out in Zhangye city.The results showed that Orchard covering with grass had obvious water conservation and the soil moisture content of soil layer of 0～60 cm was obviously higher than that of layer of unmixed grass . Soil moilsture content of soil layer of 0～20 cm in different layer was the highest. Results indicated that orchard covering with grass could restrain the evaporation of surface and accelerate the growth of fruit tree. |
