为了验证化肥减施条件下新型肥料增效剂固丹盾的作用效果，进行马铃薯大田栽培试验，对马铃薯主要农艺性状、地上植株氮含量和产量性状等进行调查测定和统计分析。结果表明，底肥采用化肥减施20%添加不同比例的固丹盾，与正常施肥相比，对马铃薯主要农艺性状有不同程度的促进作用，其中添加0.4%固丹盾效果最佳，产量较正常施肥增加6.87%。化肥减施20%并添加固丹盾实现了马铃薯化肥减施增效的效果。
Abstract：In order to test the effect of Gudandun on the fertilizer reduction, field cultivation experiment of potato is carried out, the main agronomic traits, nitrogen content of the plant and yield traits of potato are investigated,measured and statistically analyzed. The results indicate that the main agronomic traits of compound fertilizer decreased by 20% and added different concentrations of Gudandun are promoted in different degrees than the conventional dosage of compound fertilizer. Among them, the treatment of 0.4% Gudandun showes the best effect whose yield increased by 6.87% than the conventional one. Compound fertilizer decreased 20% and added Gudandun has realized the dosage reduction and efficiency increase of compound fertilizer in potato cultivation.
