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 ,品质上升 The relationship between high yield and quality of apricot on steep slope and fertilizer and water was studied through measures such as water retention project and fertilization. The results showed that the water content of apricot trees on large steep slopes was significantly increased, and the soil moisture content of root system decreased with increasing fertilizers. The renovation of big scale pit and fertilizers increased the absorption of apricot to fertilizer and water, and the transpiration intensity and chlorophyll biosynthesis Such as enhanced metabolism, leaf nutrients and fruit nutrient content increased, yield increased, quality increased
