| 摘 要： | 为了解硫酸钾镁肥在湖北高海拔地区利川辣椒上的应用效果，特与当地习惯施肥进行了比较，试验结果表明，与当地习惯施肥相比，施用硫酸钾镁肥增产效果极显著，增产幅度为13.66%，净增产值415.6元/667 m2，增产来源于辣椒果实数量和单果质量提高2个方面，两者对辣椒产量的贡献基本相当，但与氮、磷、钾平衡施用的复合肥处理对比，增产效果不明显，硫酸钾镁肥中镁的作用在此次试验中未能得到体现。

| Abstract: | Taking local conventional fertilization as control, we studied the effects of the application of magnesium potassium sulfate fertilizer on pepper in the high-altitude area of Lichuan city in Hubei. The results showed that, compared with the local conventional fertilization treatment, applying magnesium potassium sulfate fertilizer affected pepper yield significantly, and the yield-increasing rate and increased net income were 13.66% and 415.6 Yuan/667 m 2 respectively. Its yield was increased because the increase of fruit number and single fruit weight, and the two factors had almost the same contribution rate to yield increasing of pepper. But its yield was not significantly higher than that of the treatment applying with NPK compound-fertilizer, thus the role of magnesium in magnesium potassium sulfate fertilizer was failed to be reflected. |
