添加脲酶/硝化抑制剂对棉花养分吸收和产量的影响
Effects of urease/nitrification inhibitors on nutrient absorption and yield of cotton
摘要
Abstract
[Objective]To investigate the effects of urease inhibitor N-butyl thiophosphoryl triamine(NBPT)and nitrification inhibitor 3,4-dimethylpyrazole phosphate(DMPP)on nutrient uptake and yield in cotton.[Methods]Using field experiments,the tested crops were cotton Xinluzao 64 and Lumianyan 24.Four treatments were set up:no nitrogen fertilizer(N0),nitrogen fertilizer(N300),nitrogen fertilizer+urease inhibitor(N300+NBPT),and nitrogen fertilizer+nitrification inhibitor(N300+DMPP).[Results]The re-sults showed that compared to N0,all nitrogen application treatments significantly increased cotton biomass and promoted the absorption of nutrient nitrogen,phosphorus,and potassium by cotton plants.The order of nitro-gen fertilizer utilization efficiency from high to low is N300+DMPP>N300+NBPT>N300.Applying nitrogen fertilizer and urease/nitrification inhibitors can significantly increase cotton yield.The Lumianyan 24 had bet-ter nutrient absorption,nitrogen utilization efficiency,and higher yield than Xinluzao 64,but its biomass was significantly lower than that of Xinluzao 64.[Conclusion]Adding urease and nitrification inhibitors can pro-mote the absorption and utilization of nutrients by cotton plants,improve nitrogen fertilizer utilization efficien-cy,and ultimately effectively increase cotton yield.关键词
