不同密度与施肥水平对玛咖产量的影响

在海拔2730 m的云南丽江金安乡进行种植密度、纯氮用量、纯磷用量和纯钾用量4个因素的正交试验,研究不同密度和施肥水平对玛咖产量的影响。结果表明,磷肥用量和种植密度对玛咖的产量有极显著影响,而氮肥用量和钾肥用量对玛咖的影响不明显。玛咖产量较高的是第5组合和第7组合,两者差异不显著,两组合的共同点是施用的纯磷量均达600 kg/hm2。该研究结果可为玛咖的大田生产提供参考。

Effects of Different Planting Densities and Fertilization Levels on Yield of Maca (Lepidium meyenii)

The effects of different planting densities and fertilization levels on the yield of Maca(Lepidium meyenii Walp.) were studied in Jin'an township,Lijiang county,Yunnan province by orthogonal experimental design with four variable factors and three levels each factor.The results showed that the application rate of pure phosphorus and planting density had extremely significant effects on the yield of Maca;however,the other two factors(the application rate of pure nitrogen and pure potassium) had no significant effects on it.The yields of Maca in treatment 5 and treatment 7 were higher than those in other treatments,there was no significant difference in yield between treatment 5 and treatment 7,and these two treatments all applied 600 kg/hm2 pure phosphorus.The results could provide reference for the field production of Maca.
