粤北食用百合的N,P,K配比施肥研究

The study of N,P,K of edible lily in mountainous areas in the north of Guangdong

针对粤北种植百合的土壤pH值普遍偏酸性,通过在大田中试验发现,有机质含量缺乏,缺钾严重,氮素含量中等,磷素含量充足,采用NPK 3因子3水平正交设计,经多重比较,以处理3(N∶P∶K为1∶3∶3)的效果最佳。N,P,K配比施肥结果表明重施钾肥增产效果显著。

This paper studies planting soil, pests, fertilization rule and harvest of lily and discusscs main cultivation techniques of edible lily in mountainous areas in the north of Guangdong Province. The results are as follows： the lily＇s planting soil is acidic on pH and deficient of organic matter and severely deficient of soil K, but comprises mezzo N and enough P, so we should fertilize the soil with more organic fertilizer and K. Lily＇s yield would increase if the soil is fertilized with enough K, which is testified by the results of proportion of N, P, and K.
