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。
In order to explore the reasonable fertilization amount of rice in the mountain village, taking the Wuzhang paddy field of Wenxing Village, Jiuzhou Town, Xixiu Dist., Anshun City, Guizhou Province as the research area, the “3414” fertilizer experiment was conducted in 2014-2016, And the “3414” experimental data of the Wuzhang Formation were used for regression analysis to establish fertilization model based on the ground fertility. ArcGIS software was used to interpolate the soil nutrient contents of 24 randomly sampled paddy fields in Wuzhang Formation, According to the available soil nutrient content in Wuzhang Formation, the recommended fertilization amount of each block in Wuzhang Formation was obtained based on the fertilization model.
