Effects of manure of black soldier fly under different fertilization modes on rice yield and soil environment
In order to study the effects of black soldier fly manure application on rice yield and soil environment under different fertilization patterns,a field experiment was conducted in a rice field test site in Zhejiang Province.The experiment set up six treatments:no fertilization(CK),conventional fertilization(CF),black soldier fly manure nitrogen substitution(BOF),50%black soldier fly manure substitution(BCF),commercial organic fertilizer nitrogen substitution(COF),and 50%commercial organic fertilizer substitution(CCF).The effects of different treatments on rice yield,soil physicochemical properties,and enzyme activities were compared.The results showed that the application of black soldier fly manure could effectively increase soil conductivity,available potassium,and ammonium nitrogen content.The highest yield was achieved in the BOF treatment,which increased by 13.54%compared with the no-fertilization treatment,and the increase in yield was not lower than that of commercial organic fertilizers mainly made from livestock and poultry manure.
