摘要: 为提高马铃薯产量,改善马铃薯品质,减少长期施用无机肥的负面作用,采用田间试验,以不施有机肥处理为对照(CK),研究有机肥与无机肥配施[有机氮∶无机氮=2∶8(T1)、有机氮∶无机氮=3∶7(T2)、有机氮∶无机氮=4∶6(T3)]对乌兰察布市马铃薯生长发育和产质量的影响。结果表明,有机肥与无机肥配施提高了马铃薯各农艺性状指标、叶绿素含量、根干质量、产量及品质。其中,T1处理的各农艺性状指标均显著高于CK和T3处理(除主茎数外),与T2处理差异不显著;T2处理的根干质量在各时期均最高;马铃薯产量以T2处理最高,为31 572 kg/hm2,比CK提高了22.08%;淀粉含量以T3处理最高,可溶性蛋白和维生素C含量均以T2处理最高,还原糖含量则以T1处理最高。综上所述,在乌兰察布市马铃薯种植过程中有机氮替代无机氮比例以20%~30%较适宜。

Abstract: In order to improve yield and quality of potato and reduce the adverse effects of excessive use of inorganic fertilizer on environment,the field experiment was carried out to study the effects of organic fertilizer combined with inorganic fertilizer on growth, yield and quality.The experiment included the following four treatments: inorganic fertilizer(CK),organic nitrogen ∶inorganic nitrogen=2∶8( T1),organic nitrogen ∶ inorganic nitrogen=3∶7(T2),organic nitrogen ∶ inorganic nitrogen=4∶6(T3).The results showed that organic fertilizer combined with inorganic fertilizer could increase agronomic traits indexes,chlorophyll content,dry root weight,yield and quality of potato.The indexes of agronomic traits of T1 treatment were significantly higher than those of CK and T3 treatment(except for main stems number),and there was no significant difference between T1 and T2 treatments.The dry root weight of T2 treatment was the highest in each period. The yield of T2 treatment was the highest,which was 31 572 kg/ha,increased by 22.08% compared with CK.The starch content of T3 treatment was the highest;contents of soluble protein,vitamin C of T2 treatment were the highest;reducing sugar content of T1 treatment was
the highest.Overall,organic nitrogen replacing 20%—30% of inorganic nitrogen was appropriate.
