采用四因子二次通用旋转组合设计，结合大田调查与土壤肥力测试，于1994～1996年在浮山县张庄乡，对特大干旱年旱地冬小麦的施肥效应及需肥特点进行了研究。结果表明：严重干旱情况下，氮、磷、钾及有机肥的增产效应都大幅度降低，从而使产量水平仅为142．1kg／亩，较丰水年（1995～1996年）减产57．4％。在需肥特点上，大旱年则表现出严重的失衡现象，即磷、钾肥的增产效应显著大于氮肥，有机肥则介于其间。有机肥在3000～6000kg／亩范围内有显著的增产效应。施钾肥可提高小麦产量16．8％～67．2％。进一步提出了优化施肥方案。
Based on field investigation and soil fertility test, a four-factor quadratic universal rotation combination design was used to study the effects of fertilization and fertilizer requirement on winter wheat in arid dry year in 1994 and 1996 in Zhangzhuang, Fushan County. The results showed that under severe drought conditions, the yield-increasing effects of N, P, K and organic fertilizer all decreased significantly, resulting in a yield level of only 142.1 kg / mu and a decrease of 57.4 in the comparatively high water years (1995-1996) %. On the characteristics of fertilizer need, the severe drought shows a serious imbalance, that is, the yield-increasing effect of phosphorus and potassium fertilizer is significantly greater than that of nitrogenous fertilizer while that of organic fertilizer is in the meantime. Organic fertilizer in 3000 ~ 6000kg / acre within a significant yield-increasing effect. Potassium fertilizer can increase wheat yield 16.8% ~ 67.2%. Further proposed fertilization program.
