系统测土施肥技术在冬小麦上的应用效果

Effect of Systematic Fertilizer Recommendation Technology on Winter Wheat

田间试验结果表明 ,实施系统测土施肥比农民习惯施肥每公顷平均增产小麦 6 4 9 5kg ,平均增产率 9 4 % ;同时还可以改善小麦品质 ,每公顷可节约肥料投资 138 97元 ,增加纯效益 871 2 2元 ,还保持了土壤养分平衡 ,维持了地力。

Compared to farmers' conventional fertilization method, Systematic Fertilizer Recommendation Technology could increase wheat yield by 649.5kg/hm 2, 9.4% of increase rate, and reduce fertilizer investment by $138 97RMB/ hm 2, so the net profit could reach $871.22 RMB/hm 2. Additionally, Systematic Fertilizer Recommendation Technology could balance soil nutrient and maintain soil fertility for sustainable agriculture.
