The Impact of Optimal Fertilization on Nutrient Absorption and Soil Fertility in Rice Cultivation
In order to explore the effects of different fertilization treatments on rice yield and nutrient content,as well as the utilization status of the three elements of fertilizer,the formula fertilization technology of geochemical soil testing was investigated.In 2021,this paper carried out a field fertilizer efficiency experiment on fertilizer reduction and efficiency improvement in Miao Village,Binheng Town,Guangning County.The results show that in the rice fertilizer utilization experiment,the yield of N2P2K2 treatment increased compared with N0P2K2,N2P0K2 and N2P2K0 treatment,and the nutrient content and accumulation amount increased.The utilization rates of nitrogen,phosphorus and potassium fertilizers in this test were 40.29%,36.79%and 58.65%,respectively.Before and after this experiment,the soil alkaline nitrogen fertility level changed from high to low,the soil available phosphorus fertility level changed from high to extremely high,the soil available potassium fertility grade in N2P2K2 and N2P0K2 treatments remained high,and the soil available potassium fertility grade changed from high to medium in N0P2K2 and N2P2K0 treatments.Through soil testing and formula fertilization technology,soil release,fertilizer supply and crop absorption and nutrient balance can be achieved,which can promote the reduction and efficiency of chemical fertilizers,improve fertilizer utilization rates,and achieve cost savings and income increases.
