摘要
采用L9(34)正交设计试验,研究了马铃薯原种繁育中培土、密度及追肥对原种产量和效益的影响。结果表明:密度和追肥是影响原种产量的主效因子,培土1次、每公顷种植微型薯75000穴、每公顷追施尿素300 kg为最佳繁育技术方案,可实现每公顷产鲜薯35805 kg,效益54697.5元。
The effects of earth up,density and topdressing on yield and beneficial result were studied in Elite seed potato production using the orthogonal method of L9（34） to design the experimentation.The results showed that density and topdressing were main effects influencing potato yield.And the optimum cultivation measure was to earth up one time,plant minituber at 75 000 hill per hectare and apply urea at 300 kg per hectare,and as a result,a yield of 35 805 kg per hectare and earning of 54 697.5 Yuan per hectare could be achieved.
