不同有机肥替代比例对内蒙古阴山北麓地区马铃薯产量的影响
Effects of different organic fertilizer substitution ratios on potato yield in the northern foothills of Yinshan Mountains in Inner Mongolia
摘要
Abstract
[Objective]To explore the application effect and suitable substitution ratio of organic fertilizer substitute chemical fertilizer in potato production in the northern foothills of Yinshan Mountains in Inner Mongolia.[Methods]The experiment was conducted in Wuchuan County,Hohhot City,Inner Mongolia.Eight treatments were set up,including 100%M(100%organic fertilizer),75%M(75%organic fertilizer + 25%chemical fertilizer),50%M(50%organic fertilizer + 50%chemical fertilizer),25%M(25%organic fertilizer+75%chemical fertilizer),NPK(chemical fertilizer only,N 210 kg/hm2,P2O5120 kg/hm2,K2O 180 kg/hm2),no nitrogen fertilizer(PK),no phosphorus fertilizer(NK),and no potassium fertilizer(NP).The effects of different organic fertilizer substitution ratios on potato yield,nutrient accumulation,fertilizer utilization rate,and water use efficiency were analyzed.[Results]Under different organic fertilizer substitution ratios,yield,large tuber yield,small tuber yield,and number of tubers per plant of 25%M treatment were highest at 31 812,18 250,13.56 kg/hm2,and 7.90,respectively.Increased by 3.14%,2.22%,4.39%,and 23.82%compared with NPK treatment.25%M treatment had the highest increase of potato dry matter accumulation amount,and significantly higher(P<0.05)N accumulation amount compared with other treatments.Organic fertilizer increased potato fertilizer utilization rate,with 50%M treatment having the highest nitrogen fertilizer utilization rate at 43.94%.25%M treatment had the highest phosphorus and potassium fertilizer utilization rate at 17.57%,60.95%and highest agronomic efficiencies of nitrogen,phosphorus,and potassium fertilizer at 35.86%,38.98%,and 25.00%,respectively.25%M treatment had the highest water use efficiency at 125.81 kg/(hm2·mm),significantly higher(P<0.05)than other treatments.[Conclusion]25%M(25%organic fertilizer + 75%chemical fertilizer)treatment increased potato yield,nutrient accumulation,and fertilizer utilization rate,improved water use efficiency,was the optimal fertilization method for potato production in the northern foothills of Yinshan Mountains in Inner Mongolia.关键词
