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;input-output ratio was 5.4∶1.
