| 中文摘要: |
| 为了解目前广东水稻土壤肥力现状，调查了广东水稻土壤有机质、全氮、碱解氮、有效磷和速效钾含量。结果表明，与第二次土壤普查相比，广东省水稻土有机质、全氮、碱解氮和速效磷均呈上升趋势，其中处于1耀3 级的土壤分别为86.34%、94.15%、91.02%和90.62%；而土壤有效钾含量呈下降趋势，处于1耀3 级的土壤为10.54%。除土壤速效钾以外其他指标总体处于较丰富水平，建议在水稻生产中要继续注重有机肥的投入，尤其要注重钾肥的施用比例。 |

| To understand the current status of paddy soil fertility in Guangdong province, the contents of organic
matter, total nitrogen, available nitrogen, available phosphorus and available potassium were surveyed in the research.
Results showed that compared with the second soil census of Guangdong province, the organic matter, total nitrogen,
available nitrogen and available phosphorus of paddy soil increased, the proportion of grade 玉-芋soil were 86.34%,
94.15%, 91.02% and 86.34%, respectively. However, the available potassium content declined, the proportion of grade 玉-
芋soil was only 10.54%. Overall, the soil fertility indexes were rich except for soil available potassium. It was suggested
that organic fertilizer, especially potassium fertilizer should be pay more attention to rice production in Guangdong
province. |
