摘要： 在小麦拔节期、孕穗期各喷施磷酸二氢钾、硫酸钾、腐殖酸、丰产素1次,用等量清水喷施作对照。试验结果表明,喷施磷酸二氢钾增效明显,比对照增产330.0 kg/hm2,增幅9.24%;纯收益723.00元/hm2,产投比为5.4∶1。
Abstract: In wheat jointing stage and booting stage spraying potassium dihydrogen phosphate, potassium sulfate, humic acid,growth-promoter, results were compared with the same amount of water spraying（CK）. The results showed that the efficiency of potassium dihydrogen phosphate was higher than CK 330.0 kg/hm2 by 9.24%; the net benefits was723.00 yuan/hm2;inputoutput ratio was 5.4∶1.
