| Abstract: | Objective] The purpose was to explore formula fertilization technical model of konjak and guide peasants to fertilize scientifically.Method] The formula fertilization technical model of konjak was studied through experimental study with 8 treatments designed according to the principles of phosphorous(P)-potassium(K) with constant nitrogen(N),N-K with constant P and N-P with constant K.Result] Compared with conventional fertilization,the treatment effect of using N 225 kg,P2O5 97.5 kg and K2O 262.5 kg per hectare on konjak was best,its yield increased 8 399.2 kg/hm2,being 48.9% higher than CK.Its net income was up to 32 212.31 yuan/hm2,net increment was 15 430.64 yuan/hm2 than that of CK and diseased plant rate was significantly lower than that of conventional fertilization.Conclusion] Both yield and economic efficiency of using N 225 kg,P2O5 97.5 kg and K2O 262.5 kg per hectare for konjak were best. |
