摘    要:为了建立和完善安化县玉米测土配方施肥技术指标体系,实现因地制宜,分类指导,科学运筹,增产增效的目标,2006-2008年,我们选择高、中、低不同地力水平进行了连续三年玉米"3415"肥效试验,并对试验结果进行回归分析,建立了推广的肥料效应模型,得出:高肥田玉米的最佳施肥量为N178.5g/km2,P2O576.5kg/km2,K2O69.0kg/km2,最佳产量为8857.5kg/km2,施肥比例为1:0.4:0.4。中肥田玉米的最佳施肥量为N183.6g/km2,P2O569.6kg/km2,K2O119.2kg/km2,最佳产量为7059.2kg/km2,施肥比例为1:0.5:0.4。低肥田玉米的最佳施肥量为N115.5g/km2,P2O546.5kg/km2,K2O54.0kg/km2,最佳产量为6490.5kg/km2,施肥比例为1:0.4:0.5。该技术指标体系的建立,为我县中等地力水平上玉米大面积生产实现可持续发展奠定了科学基础。

关 键 词:安化县  玉米  施肥技术指标体系  最佳施肥量  最佳产量  施肥比例

Abstract:In order to establish and improve the Anhua corn soil testing Fertilization index system,to achieve local conditions,guidance,scientific logistics,increasing production andefficiency.From 2006 to2008,we have chosen the high,medium or low levels of soil fertility for three consecutive years of corn,"3415," Fertility tests,and regression analysis of test results,established to promote fertilizer effect model,Therefore,we conclude that:the best fertilizer amout of high-fertile corn is N178.5g/km2,P2O576.5kg/km...
Keywords:Anhua  corn  fertilization technology index system  the best fertilizer amout  the best yield  fertilization ratio
