摘　　要：针对渭北旱塬地区干旱少雨的气候条件，布设试验样地，采取不同覆盖材料和集水整地措施，从土壤温度、含水量等方面分析其对核桃经济林造林的影响。结果表明，造林时采取一定的微型集水工程和覆盖措施，在集流节水、抑制蒸发和保蓄土壤水分等方面是有效的，薄膜、麦秸和杂草3种覆盖材料中，以薄膜覆盖集水效果最好，含水量达到21．74％，对0～20 cm土层增温效果明显，能够显著提高造林成活率，从而提高核桃经济林的产量和质量。According to the climate conditions of drought on the Weibei dryland ,the test sample were emplaced ;adop-ting different cover materials and measures of collecting water ＆ soil preparation ,the effects of different combina-tion of temperature and water-content in soil on planting walnut forest were analyzed .Result shows that ：adopting micro-catchment works ＆ coverage measures in planting is effective at aspects of collecting water ,inhibit evapora-tion and soil moisture ;among three kinds of covering material （film ,wheat straw and weeds） ,film covering is the optimal ,water content being 21 .74% ,and the warming effect is obvious for the 0-20 cm soil;it can significantly im-prove the survival rate ,thereby enhancing the walnut forest yield and quality .
