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.

Key words: Dongyang City, long-term monitoring, maize yield, soil fertility
