摘要
[目的]推动测土配方施肥项目的发展。[方法]采用“大配方，小调整”策略，根据区域总量控制、分期调控技术，磷钾肥恒量监控技术原理，设计安徽省全椒县不同乡镇的水稻配方肥配方（基肥，区域大配方）分别为14-16-15、17-12-16、13-14-18、17-20-8、24-9-12和20-15-10。为了验证配方的适用性，2011年，选取六镇镇17-12-16的水稻配方肥，开展田间效果验证试验。[结果]试验结果表明，施用配方肥（大配方处理）比农户习惯施肥增产6.5%，增产主要源于有效穗数和穗粒数增加；配方肥的应用实现了氮磷钾元素更合理的搭配，从而实现氮肥利用率提高11.7%、磷肥利用率提高52.6%的增效作用。[结论]基于区域土壤养分供应设计的配方肥，可使农户增加收入750~4305元/hm2，效益显著。
Abstract
Objective] The aim was to promote the development of prescriptions fertilizer projects. [Method] The main fertilizer prescriptions should be designed for ecological zones and small adjustment could be done for farmer’s fields were concluded. Rice fertilizer prescription as 14-16-15、17-12-16、13-14-18、17-20-8、24-9-12 and 20-15-10 and fertilization recommendation in QuanJiao County of Anhui Province using regional soil nutrient supply and crop nutrient demand was designed by nutrient management technologies, and the fertilizer (17-12-16) in field experiment from 2011 to 2013 was evaluated. [Result] Compared with the farmers practice, the yield of treatment which using designed prescriptions fertilizer (17-12-16) increased 6.5%from 7 185 kg/hm2 to 7 653 kg/hm2, while increasing NUE of 11.7%and PUE of 52.6%. [Conclusion] Farmers could increase income of 750-4 305 yuan/hm2 by the measure of using rice prescriptions fertilizer.
