不同氮磷钾配比对玉簪驯化苗生长的影响

Effect of Different Fertilizer Mixture Ratio of N, P and K on the Growth ofDomesticated Plants of Hosta

摘要

摘要:采用“3414”试验设计,研究玉簪氮、磷、钾(N、P、K)肥施用效果,筛选适宜的肥料配方,为玉簪驯化苗科学施肥提供依据.结果表明,以V _园土:V _{腐熟蘑菇渣}:V _腐熟牛粪=1:1:1为栽培基质,适宜玉簪驯化苗生长的最佳N、P、K配比为m _N:m _P₂O₅:m _K₂O=2:3.75:2(ρ _N=0.16 g·L ^-1,ρ _P=0.3 g·L ^-1,ρ _K=0.16 g·L ^-1),该配比能较好地调节玉簪地上、地下生物量分配,促进玉簪生长,叶片数增加,提高根系活力,鲜重、叶绿素含量、叶蛋白和可溶性糖的增加.

Abstract:By use of the “3414” experiment design, the effect of N, P, K fertilizer application and appropriate fertilizer formula was studied in the hope of providing reference for scientific fertilization inHosta domestication. The result indicated that when the ratio of the culture substrate is controlled at V _{garden soil}: V _rotten _{mushroom residue}: V _{rotten cattle manure}=1:1:1, the best fertilizer ratio of N, P and K for Hosta growth wasm N: P ₂O ₅: K ₂O = 2:3.75:2(ρ _N=0.16 g·L ^-1, ρ _P=0.3 g·L ^-1, ρ _k=0.16 g·L ^-1), which can nicely adjust the distribution of aboveground and underground biomass, and also promote growth, increase the number of leaves, improve root activity, and increase fresh weight, chlorophyll content, leaf protein and the soluble sugar of Hosta.
