摘要:

本研究根据2014—2022年东阳市省级耕地质量监测点的监测数据,分析了在有机肥替代化肥背景下东阳市玉米产量和土壤肥力的变化趋势,明确了有机肥施用对玉米产量与土壤肥力的影响。监测结果表明,通过优化施肥,在每667 m2增施260 kg商品有机肥的基础上,化学氮、磷和钾肥的施用量分别减少了19.1%、14.3%和27.3%;玉米产量有所增加,每667 m2年均增产约74.9 kg,增产率为11.0%。同时,有机肥的施用,可在一定程度上抑制土壤酸化,提高土壤有机质和全氮、有效磷和速效钾含量,提高作物养分吸收和肥料利用效率,从而实现了化肥减量增效。本研究结果为该地区玉米生产中有机肥替代化肥提供了理论依据,有利于推动玉米的可持续生产。

Abstract:

Based on the monitoring data of provincial-level farmland quality monitoring points in Dongyang City from 2014 to 2022,this study analyzed the changing trends of maize yield and soil fertility under the background of organic fertilizer replacing chemical fertilizer,and clarified the effect of organic fertilizer application on maize yield and soil fertility. The monitoring results over 10 consecutive years showed that by optimizing fertilization,with an additional application of 260 kg of commercial organic fertilizer per 667 m2,the application amounts of chemical nitrogen,phosphorus and potassium fertilizers were reduced by 19.1%,14.3% and 27.3% respectively;and the maize yield increased,with an average annual increase of 74.9 kg per 667 m2,and an increase rate of 11.0%. At the same time,the application of organic fertilizer can,to a certain extent,inhibit soil acidification,increase soil organic matter,total nitrogen,available phosphorus and available potassium contents,improve crop nutrient absorption and fertilizer utilization efficiency,and thus achieve the goal of reducing chemical fertilizer application while increasing efficiency. The results of this study provided a theoretical basis for the substitution of organic fertilizer for chemical fertilizer in maize production in this region,which was conducive to promoting the sustainable production of maize.
