根据黄土丘陵区土壤肥力特点及土体结构，选用硝酸铵和过磷酸钙作为试验肥料，进行了不同施肥量试验。结果表明，黄土丘陵区穴施磷肥的效果要比传统的施肥方法效果好，最佳施肥量为1．0kg／株～1．5kg／株；枣树对硝铵反应十分敏感，施肥量必须严格控制，黄土丘陵区硝铵的最适施肥量为0．10kg／株～0．25kg／株，过多或过少都会明显影响枣树的吊果率和产量。 According to the characteristics of soil fertility and soil structure in loess hilly region, ammonium nitrate and superphosphate were selected as experimental fertilizers, and different fertilizers were tested. The results showed that the effect of applying P fertilizer on loess hilly region was better than that of traditional fertilization method, and the optimum fertilizer was 1.0kg / plant ~ 1.5kg / plant. Jujube tree was very sensitive to ammonium nitrate reaction and the amount of fertilizer application must be strict Control, the optimum fertilizer amount of ammonium nitrate in loess hilly region is 0.10kg / plant ~ 0.25kg / plant, too much or too little will significantly affect the jujube fruit rate and yield.
