The“3414” Fertilizer Effect Test onWheat in Low Fertility Fields of Zhenfeng County
[Objective]The aim was to explore the optimal fertilization ratio of nitrogen,phosphorus and potassium fertilizers for wheat in low fertility fields of Zhenfeng county.[Method]Through field experiments on the"3414"fertilizer effect of wheat,the yield of wheat under different fertilization treatments was analyzed and compared to determine the optimal fertilization ratio.[Result]The application of different ratios of nitrogen,phosphorus,and potassium fertilizers had different effects on the agronomic traits and yield of wheat.When the fertilization amount was N 390 kg/hm2,P2O5750 kg/hm2,and K2O 124.5 kg/hm2,the wheat yield was the highest,with a yield of 4 971.0 kg/hm2,which was 2 131.5 kg/hm2 higher than that in the unfertilized area.[Conclusion]Under the same fertility conditions as the test,the recommended optimal fertilization amounts for wheat cultivation are N 390 kg/hm2,P2O5750 kg/hm2,and K2O 124.5 kg/hm2.
