摘要
以‘兴佳2号’马铃薯为材料,在减施化肥22.22%~50.00%的基础上,研究有机肥与化肥配施(T1,生物有机肥600 kg/hm^(2)+复合肥1125 kg/hm^(2))、微肥与化肥配施(T2,微肥60 kg/hm^(2)+复合肥1125 kg/hm^(2))、有机无机互混肥(T3,1500 kg/hm^(2))、复合微生物肥(T4,1500 kg/hm^(2))和螯合腐植酸复合肥(T5,937.5 kg/hm^(2))等施肥方式及常规施肥对照(CK1,复合肥1500 kg/hm^(2))、减量施肥对照(CK2,复合肥1125 kg/hm^(2))、不施肥对照(CK3)对马铃薯生长、产量和品质的影响。结果表明:与CK1相比,T5、T1和T2可促进马铃薯植株的生长;T5、T2和T1产量分别比CK1增产19.82%、11.65%和8.2%,养分利用效率分别比CK2提高74.87%、57.75%和50.52%;CK2比CK1减施化肥25%,产量仅降低3.21%,养分利用效率提高了26.61%;各处理间干物质、淀粉、V–C、蛋白质、钾、还原糖含量等差异显著。在减施化肥25%的基础上,螯合腐植酸复合肥及生物有机肥或微肥与复合肥配施促进了马铃薯植株的生长,较大幅度提高了产量、品质和养分利用效率。
Based on reducing chemical fertilizer by 22.22%to 50.00%,Xingjia No.2 potato was used as material to study the effects of combined application of biological organic fertilizer and chemical fertilizer(T1,biological organic fertilizer 600 kg/hm^(2) and compound fertilizer 1125 kg/hm^(2)),combined application of micronutrient fertilizer and chemical fertilizer(T2,micronutrient fertilizer 60 kg/hm^(2) and compound fertilizer 1125 kg/hm^(2)),organic-inorganic mixed fertilizer(T3,1500 kg/hm^(2)),compound microbial fertilizer(T4,1500 kg/hm^(2)),chelated humic acid compound fertilizer(T5,937.5 kg/hm^(2)),conventional fertilization control(CK1,compound fertilizer 1500 kg/hm^(2)),reduced fertilization control(CK2,compound fertilizer 1125 kg/hm^(2))and no fertilization control(CK3)on the growth,yield and quality of the potato.The results showed that T5,T1 and T2 could promote the growth of potato plants compared with CK1.Compared with CK1,the yield with T5,T2 and T1 increased by 19.82%,11.65%and 8.2%respectively,and nutrient use efficiency increased by 74.87%,57.75%and 50.52%respectively.Compared with CK1,fertilizer application in CK2 reduced by 25%,but the yield in CK2 reduced only by 3.21%while the nutrient use efficiency increased by 74.87%.There were significant differences in tuber qualities including contents of dry matter,starch,V-C,protein,potassium,reducing sugar contents among different treatments.Hence,under the condition of 25%reduction of chemical fertilizer,the application of chelated humic acid compound fertilizer and biological organic fertilizer or micronutrient fertilizer combined with compound fertilizer promoted the growth of potato plants,significantly increased the tuber yield,tuber quality,and the nutrient utilization efficiency.
