| 摘 要： | 为探究山地村域水稻合理施肥量,以贵州省安顺市西秀区旧州镇文星村吴章组稻田为研究区域,于2014-2016年进行"3414"肥料试验,对3年11个点的"3414"试验数据进行回归分析,建立基于地力的施肥模型;利用ArcGIS软件对吴章组稻田24个随机取样点土壤各养分含量进行插值分析,生成吴章组稻田土壤各有效养分含量分布图,预测吴章组所有田块土壤有效养分含量;根据吴章组田块土壤有效养分含量,应用基于地力施肥模型,获得吴章组各田块的推荐施肥量。

| Abstract: | In order to explore rational fertilization of rice at village-region in mountainous area, the'3414' fertilizer experiment was carried out in Wuzhang Group, Wenxing Village, Jiuzhou Town, Xixiu District, Anshun City, Guizhou Provincein in 2014-2016. The fertilization model is set based on the experiment data from 11 different testing points in 2014-2016 by regression analysis. The dis-tribution maps of each soil available nutrient content (SANC) were created respectively by spacial interpolation analysis, the data of SANC from 24 random sampling points at the testing field through ArcGIS software, and predicted the SANC of all Wuzhang Group's fields. So we could give suitable fertilization amounts for the fields according to the SANC calculated by the fertilization model based on the soil fertility. |
