通过对无灌溉条件的半干旱坡地油橄榄园进行覆盖和深翻试验,研究了不同保水措施下油橄榄园土壤含水量、新梢生长量及深翻后根系变化。结果表明:土壤含水量不同保水措施间存在差异,覆盖提高了园地土壤含水量,以薄膜最高,秸秆覆盖最小。随着土壤深度增加,不同覆盖处理之间土壤水分含量具有差异性。深翻则改变了土壤结构,改善持水能力,修剪根系,促进树体健壮生长。 The effects of different water conservation measures on soil water content, shoot growth and root system change after deep-rooting were studied by covering and deep-tipping the semi-arid slope olive grove without irrigation. The results showed that there was a difference between the different water conservation measures in soil moisture content, covering the increase of soil moisture in the field, with the highest film and the smallest straw cover. With the increase of soil depth, the soil moisture content of different cover treatments is different. Deep plowing has changed the soil structure, improve water holding capacity, pruning the root system, and promote the robust growth of trees.
