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。
針對渭北旱塬地區榦旱少雨的氣候條件,佈設試驗樣地,採取不同覆蓋材料和集水整地措施,從土壤溫度、含水量等方麵分析其對覈桃經濟林造林的影響。結果錶明,造林時採取一定的微型集水工程和覆蓋措施,在集流節水、抑製蒸髮和保蓄土壤水分等方麵是有效的,薄膜、麥秸和雜草3種覆蓋材料中,以薄膜覆蓋集水效果最好,含水量達到21.74%,對0~20 cm土層增溫效果明顯,能夠顯著提高造林成活率,從而提高覈桃經濟林的產量和質量。

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 .
