| 摘 要： | 为了提高作物的产量和品质,做到配方施肥,采集了天津市东丽地区葡萄园和北辰区菜园土壤样本,测定了土壤速效氮、速效磷、速效钾的含量以及土壤容重。结果显示:东丽区葡萄园的速效氮含量较低,处于5级;北辰区菜园速效氮含量处于3级,中等水平。东丽区葡萄园的速效磷含量处于3级;北辰区北部菜园速效磷含量处于2级,含量较高,南部菜园速效磷含量处于3级。各供试土壤的速效钾含量均为4级,处于中下等水平。北辰区菜园的土壤肥力水平高于东丽区葡萄园肥力水平,北辰区菜园的土壤容重大于东丽区葡萄园的土壤容重。东丽、北辰两个地区的土样中速效钾的含量略低于天津地区的平均含量,速效氮远远高于天津地区的平均含量,速效磷低于天津地区的平均含量1倍以上。所以,这两个园子应该主要补充磷肥,减少氮肥的施用量。 |

| Abstract: | The content of soil available N, P and K and soil bulk density of vineyard in Dongli and kaleyard in Beichen were analyzed in order to enhance crop yield and quality. The result showed that the soil available N content of the vineyard was low and in grade 5 while that was in grade 3 in the kaleyard. The soil available P content was in grade 3 in the vineyard, grade 2 in north of kaleyard and grade 3 in south of kaleyard. The soil available K content was in grade 4. The soil nutrient fertility in kaleyard was higher than that in vineyard. Soil bulk density of kaleyard was larger than that in vineyard. The soil available K content of Dongli and Beichen was a little lower than the average of Tianjin, the soil available N content was much higher than the average, the soil available P content was above one time lower than the average. P fertilizer should be supplied and N fertilizer should be decreased in these two yards. |
