摘　　要：小青菜田间试验表明,与常规施肥相比,增施7.5 t·hm^(-2)厨余垃圾为原料的有机肥,对小青菜产量有增产作用,但未达到显著性水平;对土壤有机质含量有显著提升作用,提升幅度为15.6%;土壤容重下降0.12 g·m^(-3)、田间持水量增加2.7百分点,有助于提高土壤透气性和保水保肥能力。当施用供试厨余垃圾有机肥30 t·hm^(-2)时对小白菜生长存活产生了负面效果;供试厨余垃圾有机肥安全施用量应小于22.5 t·hm^(-2)为宜。The field experiment of Brassica chinensis showed that 7.5 t·hm^(-2) organic fertilizer with kitchen waste as raw material increased the yield of Brassica chinensis,but it did not reach the significant level;Soil organic matter content was significantly increased by 15.6%,soil bulk density decreased by 0.12 g·m^(-3),and field moisture capacity increased by 2.7 percentage points.When applying 30 t·hm^(-2) of organic fertilizer from kitchen waste,it had negative effect on the growth and survival of Brassica chinensis,and the safe application amount of organic fertilizer from kitchen waste should be less than 22.5 t·hm^(-2).
