| 摘 要： | 黄土高原连续3年的定位试验结果表明:旱地施用有机肥具有明显的培肥作用和蓄水保墒效果；平均每1hm2施有机肥112500kg，土壤有机质、全氮、速效氮、磷、钾含量试验后比试验前分别提高了36.4%、21.7%、49.7%、16.2%和44.2%，0～60cm土壤含水量比对照增加5.5mm；每1mm降水多生产小麦1.83kg，水分利用效率提高22%；小麦增产15.8%.施肥量与产量之间呈显着正相关。

| Abstract: | Through a three year fixed field experiment, the results showed that applying manure had a significant fertilizing soil and water conversation effect;giving 112 500 kg/hm2 amount of manure, the contents of soil organic matter;total N, available N, available P and available K increased individually 36.4%, 21.7%, 49.7%, 16.2%, 44.2%, the water content of 0~60 cm soil layer increased 5.5 mm;1 mm rainfall could producemore 1.83 kg wheat and water use efficiency increased 22%;wheat yield increased by 15.8%.There is a prominent correlation between the applying amount and yield. |
