摘　　要：为进一步验证增施有机肥对改善土壤理化性状和提升奶白菜产量的效果,开展奶白菜增施有机肥试验。结果表明,在当地土壤状况下,增施适量的有机肥并配施化肥,与单施化肥相比,土壤中的有机质、全氮、有效磷和速效钾含量分别增加4.32%~5.76%、3.90%~9.09%、2.91%~7.72%和7.64%~10.25%,土壤容重降幅为1.97%~6.58%。在减少28.6%化肥的基础上增施有机肥2625 kg/hm^(2),较常规单施化肥显著提高奶白菜产量4.43%(P<0.05)。因此,在奶白菜生产中,有机肥与化肥合理配施可以改善土壤理化性状并实现增产。In order to further verify the effect of increasing organic fertilizer on improving soil physicochemical properties and increasing yield of milk cabbage,the test on increasing organic fertilizer in milk cabbage was carried out.The results showed that under the local soil conditions,when adding moderate organic fertilizer and applying chemical fertilizer,the contents of organic matter,total nitrogen,available phosphorus and available potassium in the soil increased by 4.32%-5.76%,3.90%-9.09%,2.91%-7.72%and 7.64%-10.25%respectively,and the soil bulk density decreased by 1.97%-6.58%,compared with those of applying chemical fertilizer alone.On the basis of reducing 28.6%of chemical fertilizer,adding 2625 kg/hm^(2) of organic fertilizer significantly increased the yield of milk cabbage by 4.43%(P<0.05)compared with conventional applying chemical fertilizer alone.Therefore,in the production of milk cabbage,the reasonable combination of organic fertilizer and chemical fertilizer can improve soil physicochemical properties and increase yield.
