不同配方营养液对水培高羊茅的影响

目的]为了探索适合草坪水培栽培的营养液。方法]以高羊茅(Festuca arundinacea)为材料,进行不同营养液配方对水培高羊茅生长的影响研究。结果]在5种营养液配方中,霍格兰营养液培养的高羊茅株高、单株叶片数、单株分蘖数、植株鲜干重(生物量)以及根系活力等各项指标最好,是高羊茅水培的最佳营养液配方,斯泰纳配方培养的高羊茅各项指标最差,与其他营养液配方之间差异显著,故不适宜作为高羊茅水培的营养液。结论]该研究可为水培建植草坪所需营养液选择提供参考,并为草坪水培技术的进一步研究提供参考。

Effects of Different Nutrient Solutions on Hydroponic Tall Fescue(Festuca arundinacea)

Objective] The aim was to explore the suitable nutrient solution for turf hydroponic.Method] The effects of five hydroponics nutrient solution formulas on tall fescue growth were studied.Result] The results showed that the indicators of tall fescue turfgrass cultivated by Hoagland solution formula,such as the plant height,leaf number,plant biomass,number of tillers and root vigor,were the higher than those of the other formulas.The indicators of tall fescue turfgrass under Steiner formula were the lower than those of the other formulas.It was suggested that Hoagland formula was the best suitable for the tall fescue hydroponic in five formulas and Steiner formula was not suitable.Conclusion] The study provides a reference for selecting nutrient solutions planting lawn by hydroponic cultivation,and researching lawn hydroponic technology deeply.
