| Abstract: | In order to study the question of maize fertilization in Guizhou Province, we did a field experiment usingL9(34) NPK three factors three level test in Pingba County. The effect of applying fertilizer on nutrition characteristic of corn Qianxing 201 and its output were studied by preparing different treatments of nitrogen(N), phosphorus(P), and potassium(K). The results showed that when combine the N of 360 kg, P2O5 of 225 kg, K2O of 105 kg each hm2 of area can remarkably enhance the output and quality of com. The results provides a theoretical basis of instructing production of corn and rational application of fertilizer. |
