摘要
为研究不同施肥模式下施用黑水虻虫粪肥对水稻产量及土壤环境的影响,该研究在浙江省稻田试验点开展田间试验.分别设置不施肥(CK)、常规施肥(CF)、黑水虻虫粪肥等氮替代(BOF)、50%黑水虻虫粪肥替代(BCF)、商品有机肥等氮替代(COF)、50%商品有机肥替代(CCF)6 个处理,对比不同处理对水稻产量及土壤理化性质、酶活性的影响.结果表明,施用黑水虻虫粪肥可有效提升土壤电导率、速效钾、铵态氮含量,BOF处理产量最高,较不施肥处理增产 13.54%,增产效果不低于以畜禽粪污为主要原料的商品有机肥.
Abstract
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.
