| 摘 要： | 在土壤钾素含量中等偏下的宝坻区和西青区辛口镇第六埠,研究了钾肥对27种蔬菜产量的影响及钾素的吸收特性、利用率。在宝坻区施用钾肥可使蔬菜平均产量增加9.4 t/hm2,增产率21.8%,增收5 055.5元/hm2;在第六埠村施钾平均产量增加7.2 t/hm2,增产率19.2%,增收8 692元/hm2。叶菜类钾素吸收量较低,吸收趋势是叶菜类〈果菜类〈根菜类〈根茎类。蔬菜钾肥平均利用率26.93%,果菜类30.18%>瓜菜类28.81%>根茎类25.83%>叶菜类22.91%。

| Abstract: | Field experiments were arranged to study effect of K fertilizer on yield,K absorption and utilization rate of 31 kinds of vegetables in Baodi and Xiqing District.The yield increased 9 900 kg/ha and income increased 5055.5 yuan/ha because of K fertilizer application in Baodi District.The yield increased 7 200 kg/hm2 and income increased 8 692 yuan/hm2 in Xiqing District.The K absorption of leaf vegetables(except caraway) was lower than that of fruit and root vegetables.The K utilization rate of fruit vegetables,root vegetables and leaf vegetables was 30.18%,25.83% and 22.91%,respectively. |
