马铃薯“2+X”施肥试验

Potato"2+X"Fertilization Test

马铃薯生产中,科学施肥可培肥地力,增加马铃薯产量,改善其品质,提高经济效益。为优化户马铃薯生产中的施肥习惯,减少不合理的施肥现象,提高肥料利用率,研究最优的施肥量模式,设计了马铃薯“2+X”施肥试验。对比分析不同氮肥水平条件下马铃薯经济性状与产量的变化,通过回归分析,得出当地土壤养分条件下,每0.067 hm^(2)施纯氮13.07 kg,可获得最高产量为2600.56 kg/0.067 hm^(2)。

In potato production,scientific fertilization can increase soil fertility,increase potato yield,improve its quality and economic benefits.In order to optimize the fertilization habit in household potato production,reduce the unreasonable fertilization phenomenon and improve the utilization rate of fertilizer,studied the optimal fertilizer application model and designed the potato"2+X"fertilization experiment.Compared and analyzed the changes of potato economic traits and yield under different nitrogen fertilizer levels,under the condition of local soil nutrient,by applying 13.07 kg pure nitrogen per 0.067 hm^(2) can be obtained the highest yield of 2600.56 kg/0.067 hm^(2).
