Abstract

For study the effects of different formula fertilization on sweet potato,a field experiment was carried in central Guizhou.The results showed that: formula fertilizer application can significant increasing the branch,the sweet potato vines,the biomasses and so on.In different treatment,the effects were different;Applying fertilizer should be appropriate,suitable application of manure is useful.The highest yield was obtained when recommended amount was adopting N135 kg/ha、P2O567.5 kg/ha、 K2O 202.5 kg/ha for sweet potato in this area.Compared to the CK,it was increased 22.12%.Following the recommendation will get high yield.
