| 摘 要： | 为探明长期轮作与施肥对马铃薯土壤养分和产量的影响,采用随机区组设计,研究了9 a(年)间不同肥料配比对马铃薯与杂粮轮作土壤养分含量的影响。结果表明,经过9 a轮作与施肥,磷钾肥区旱作土壤有机质含量从2011年的6.46 g·kg-1上升到2019年的11.79 g·kg-1,土壤速效养分含量总体呈现出缓慢递增的趋势,全量养分含量呈递增-降低-递增-降低的“M”态势,不同氮磷钾肥配比对马铃薯增产效果显著,在2019年产量达到最高,为12015 kg·hm-2。综上所述,经过9 a的长期轮作与施肥后,土壤质量明显提高。

| Abstract: | In order to investigate the effects of long-term crop rotation and fertilization on soil nutrient and yield of potato,the effect of different fertilizer ratio on soil nutrient content of potato and multi-grain rotation was studied by random block design.The results showed that after nine years of rotation and fertilization,dry land soil organic matter was increased from 6.46 g·kg-(12011)to 11.79 g·kg-1(2019),soil available nutrient content presented a slowly increasing trend,the total amount of nutrient content showed an"M"trend of increasing-decreasing-increasing-decreasing,the effect of different N,P and K fertilizer ratio on potato yield increase was significant,the annual output reached the highest at 12015 kg·hm-2 in 2019.In conclusion,after 9 years of rotation and fertilization,the soil quality was significantly improved. |
