| 摘 要： | 对豫南稻区不同施钾处理在水稻、小麦和油菜三种作物上的产量效应进行了田间试验研究。结果表明,施钾处理增加效果明显,其中稻田和麦田施钾124.5kg/hm2处理,油菜田施钾186.75kg/hm2处理与对照相比增产效果最明显。水稻、小麦、油菜分别在施钾146.6kg/hm2、145.6kg/hm2、183.6kg/hm2时的产量最高,单位面积产量分别为6869.3kg/hm2、3517.1kg/hm2、2424.2kg/hm2。

| Abstract: | The effects of potassium(K) fertilizer application on the yield of rice,wheat,and rape was carried out with field trial in a rice-plant region of south Henan province.The results showed that K fertilizer could significantly increase the crop yield.The yield was significantly increased with 124.5kg/hm2,124.5kg/hm2 and 186.75kg/hm2 of K application treatments in rice,wheat and rape fields,respectively.The highest yield of rice,wheat,and rape,through calculation of the equation,was 6869.3 kg/hm2,3517.1 kg/hm2,2424.2 kg/hm2 with 146.6 kg/hm2?145.6 kg/hm2?183.6 kg/hm2 of K fertilizer input,respectively. |
