分析了不同施肥对土壤物理性状及产量的影响 ,同时也分析了前作玉米施肥对后作大豆产量及子粒外观品质的影响。结果表明 ,单施化肥能提高作物产量 ,但土壤结构有变劣的趋势 ,有机农肥与化肥配施不仅能提高作物产量 ,而且土壤有机质含量呈增加趋势 ,有利于土壤物理环境的改善。前作玉米施农肥对后作大豆提高产量及改善子粒外观品质都有促进作用 The effects of different fertilization on soil physical properties and yield were analyzed. The effects of pre-fertilization on yield and grain appearance quality of post-crop corn were also analyzed. The results showed that single application of chemical fertilizers could improve the yield of crops, but the soil structure tended to deteriorate. The combination of organic fertilizer and chemical fertilizer could not only increase crop yield, but also increase the content of soil organic matter, which is beneficial to the improvement of soil physical environment. The pre-corn application of fertilizers promoted the yield of post crop soybean and improved the quality of grain appearance
