种植密度与施肥量对桂玉505产量的影响

Planting density and fertilization amount's influence on yield of Maize "Guiyu 505"

采用裂区设计,探讨不同种植密度配合不同施肥量配比对桂玉505产量的影响。试验结果表明,不同种植密度与不同施肥量配比的交互作用极显著,表明不同密度适用于不同的施肥量配比,其中以施纯N∶P2O5∶K2O(kg/hm2)=270∶90∶270的施肥配比配合种植密度为4.8万株/hm2时产量最高。

In this experiment, separated plots design is used to research different planting densities and various fertilization amounts＇ influence on yield of Maize ＂Guiyu 505＂. The results show that the interaction of experimental factors arrived 1% significance level, indicating that different densities are suitable to various fertilization amounts, among which, the combination of N ： P205 ： K20（ kg/hm^2 ） = 270：90：270 and planting density of 48,000 seedlings/hm^2 can produce highest yield.
