不同施肥处理对马铃薯产量和品质的影响

Effects of different fertilization formulations on potato quality and yield

【目的】探究不同施肥处理对内蒙古乌兰察布市马铃薯主栽品种产量及品质的影响。【方法】以当地马铃薯主栽品种冀张薯12号、克新1号和晋薯16号为试验材料,设置不施肥(空白)、常规施肥(CK)、施复合肥、常规施肥配施微生物菌剂4种不同施肥处理,测定马铃薯产量、商品薯率和品质指标。【结果】常规施肥配施微生物菌剂可提高3个马铃薯品种的产量和商品薯率,显著提高冀张薯12号和克新1号干物质含量(P<0.05),显著提高克新1号蛋白质含量(P<0.05),极显著提高冀张薯12号的还原糖含量(P<0.01);各处理间3个品种的VC含量无显著差异(P>0.05)。【结论】常规施肥配施微生物菌剂可有效提高乌兰察布市马铃薯主栽品种的产量,改善其品质。

【Objective】To explore the effects of different fertilization formulations on the yield and quality of main potato varieties in Ulanqab,Inner Mongolia.【Methods】To determine the yield,commercial rate,and quality index of potato,four different fertilization treatments were set up using Jizhangshu No.12,Kexin No.1,and Jinshu No.16 as experimental materials.The treatments were no fertilization(blank),conventional fertilization(CK),compound fertilization,and conventional fertilization combined with microbial agents.【Results】Conventional fertilization combined with microbial agents increased the yield and commercial rate of the three potato varieties,significantly increased the dry matter content of Jizhangshu No.12 and Kexin No.1(P<0.05),significantly increased the protein content of Kexin No.1(P<0.05),and extreme significantly increased the reducing sugar content of Jizhangshu No.12(P<0.01).There was no significant difference in VC content among the three varieties(P>0.05).【Conclusion】Conventional fertilization combined with microbial agents boosted the yield and quality of main potato varieties in Ulanqab.
