在西南农业大学国家紫色土肥力与肥料效益监测基地上，研究多年定位施钾对紫色土水稻、小麦产量品质的影响。研究结果如下：定位试验初期(1992年)，钾肥对小麦无增产效果，每千克K2O仅增产水稻5．9kg；8年定位试验后的1999年，每千克K2O增产小麦9．4kg，增产水稻14．8kg；这表明经过8年定位试验，钾素已成为紫色土水稻、小麦进一步提高产量的重要因素。同时，钾肥还能明显改善稻、麦品质。

The experiment, the purpose of which is to study the effects of fix-point applied potassium on the yield and quality of wheat and rice, was carried out on the National Purple Soil Fertility and Fertilizer Efficiency Monitored Base in Southwest Agricultrual University. The results are as follows: In 1992, the wheat's yield increased by 0kg and the rice's by 5.9kg with 1kg more K2O application; but in 1999, the former increased by 9.4kg and the later by 14.8kg. These show that potassium has been an important factor to the further improvement of rice and wheat's grain yield in purple soil after 8year fixed position experiment; and that potassium can evidently improve the quality of rice-wheat.
