摘要
通过田间试验,研究了不同施肥方式对菜园土壤环境质量及作物产量的影响.结果表明：在试验设计范围内,施肥增加了土壤pH值和重金属Cu和Zn的含量,使土壤硝态N含量增加了9.85%～85.56%;在同一施肥条件下,施用养分促进剂或生物农药可降低土壤中硝态N的含量;施肥量的增多能显著增加辣椒产量,施用氮肥525kg/hm^2＋化学农药处理的产量最高,与对照相比增加了78.93%.
Effects of different fertilizing modes on soil environment quality and crop yield of kailyard were studied through field experiment. The results showed that applying fertilizer could increase pH value, the content of heavy metal Cu and Zn of the soil as well as the nitrate N content in the soil by 9.85% -85.56%. Under the identical condition of fertilization, applying the nutrient promoter or biological pesticide could reduce nitrate N content in the soil. The yield of hot pepper increased significantly as the application of fertilizers increased, the yield in the treatment D （applying 525kg/hm^2 N fertilizer ＋ chemical pesticide） was maximum, which increased by 78.93% than that of the CK.
