不同的土壤类型和施肥量会对马铃薯产量和品质产生不同程度的影响。下文以紫色土、石灰岩红壤、第四纪红土、河流冲积土以及板页岩红壤等5种土壤为例,测试在每667 m2施氮(N)、磷(P)、钾(K)复合肥50 kg(标记为处理1)、75 kg(标记为处理2)、100kg(标记为处理3)以及125 kg(标记为处理4)的情况下,对马铃薯品质和产量的影响,探讨如何选择合适的土壤进行马铃薯种植,以及通过合理施肥提高马铃薯的产量和品质。
Different types of soils and fertilizers can have varying degrees of impact on potato yield and quality. Taking purple soil, limestone red soil, Quaternary laterite, river alluvial soil and red shale as an example, the effects of nitrogen (N), phosphorus (P) and potassium (K) Effects of 50 kg (labeled Treatment 1), 75 kg (labeled Treatment 2), 100 kg (labeled Treatment 3), and 125 kg (labeled Treatment 4) on potato quality and yield were explored on how to choose the right Of the soil for potato cultivation and to increase the yield and quality of the potato through proper fertilization.
