试验主要对不同形态尿素进行追肥对比,通过在马铃薯追肥期施用尿素液肥,比较追施尿素液肥与常规氮肥对马铃薯生长产生的效果差异,以及不同尿素液肥间的差别和产生的综合效益,为种植户科学合理选择新型肥料、科学施肥、增产控肥提供参考依据。试验结果表明:马铃薯追施尿素液肥后,产量显著提高,较农民传统追施普通尿素亩平均增产694.5kg,商品薯率平均提高1.5%。
The experiment mainly compared the top dressing of different forms of urea. Through the application of urea liquid fertilizer in the top dressing period of potato, the difference in effect of topdressing urea fertilizer and conventional nitrogen fertilizer on the potato growth was compared with that of the urea urea fertilizer. Household science and reasonable selection of new fertilizers, scientific fertilization, increase production control provide a reference. The results showed that the yield of potato topdressing urea fertilizer was significantly increased, which increased 694.5kg on average compared with that of traditional topdressing urea and the average yield of potato products increased 1.5%.
