摘　　要：通过保水工程和增施肥料等措施研究了陡坡地杏树高产优质与肥水的关系。结果表明 ,陡坡地杏树整修大鱼鳞坑土壤含水量明显提高 ,增施肥料根系土壤含水量降低 ;整修大鱼鳞坑并增施肥料使杏树对肥水的吸收作用提高 ,叶片蒸腾强度和叶绿素合成等代谢作用加强 ,叶片养分和果实养分含量增加 ,产量提高 。Apricot is one of the good trees to be used for controlling and exploiting sloping field,which the slope degree is larger than 25 degree on leass hilly gully region in North Shaanxi.The relationship between water & fertilizer of and high yield & fine quality of apricot on sloping field had been studied by the water conversation project, using more fertilizer,etc, the results showed that: The water content in soil could be increased clearly with building big Yulinkeng (rhegmalypt), and the water content in soil of root region can be decreased with the increase of the amount of fertilizer for apricot on sloping field.The absorption apricot absorbability to water and fertilizer was increased by combining building big Yulinkeng (rhegmalypt) with raising the amount of fertilizer, the transpiration intensity and chlorophyll synthetic of leaves could be raised, the yield and the quality was increased too. As a result, we think it is one of the most effective ways to get high yield and fine quality of apricot.
