摘　　要：对溧水白马地区种植年限为3、5、8年且采用不同栽培方式的蓝莓基地土壤进行采样,研究了蓝莓不同栽培方式对土壤质量的影响。结果表明:在相同种植年限的蓝莓地块上,土壤有机质、全氮、碱解氮和速效钾含量及有关土壤酶活性均呈现有机栽培>外部低投入栽培>常规栽培的趋势;随着种植年限的增加,土壤养分含量和土壤酶活性均有所提高。表明有机栽培方式更有利于提高土壤肥力,促进农业可持续生产。Soil samples from blueberry gardens cultivated by different patterns for 3, 5 and 8 years respectively in Baima town, Lishui county were analyzed, and the effect of different cultivation patterns of blueberry on soil quality was studied. The results showed that ： in the blueberry garden with the same planting years, the contents of organic matter, total nitrogen, alkali - hydrolys- able nitrogen and available potassium in the soil of organic cultivation blueberry garden all were the highest, followed by those of ex- ternal low - input cultivation blueberry garden, while those of conventional cultivation blueberry garden were the lowest. The activity of soil enzymes also showed the same trend. Soil nutrient content and soil enzyme activity both increased with the incree of plant- ing years. In summary, as compared with the external low - input cultivation and conventional cultivation, organic cultivation was more conducive to the improvement of soil fertility and the sustainable production of agriculture.
