摘要
分析了不同椰糠、泥炭土配比的栽培基质的理化性质、保水保肥能力,筛选出适宜模块式垂直绿化植物生长的栽培基质,为模块式垂直绿化的可持续发展提供依据。以不同椰糠、泥炭土配比的栽培基质为研究对象,测定各配比的容重、孔隙度、酸碱度、吸水率、碱解氮、速效磷及速效钾,同时以不同配比基质应用至模块式垂直绿化墙体上观测小叶龙船花、黄金榕、红桑、福建茶的生长指数。结果表明:随着泥炭比例的增加,椰糠比例的降低,配比基质的孔隙度、pH值、吸水率逐步升高,容重、碱解氮、速效磷、速效钾逐渐增大,对小叶龙船花、黄金榕、红桑和福建茶生长的影响大小程度分别为T3>T4>T2>T5>T1、T3>T2>T4>T1>T5、T3>T4>T2>T5>T1、T4>T3>T2>T5>T1。结果表明:以泥炭土、椰糠为主原料的模块式垂直绿化栽培基质的椰糠+泥炭土的占比在60%+20%至20%+60%之间为宜,其中以各占40%左右的比例为最佳配比,更有利于绿化植物的生长。
The physical and chemical properties,water and fertilizer retention capacity of cultivation substrates with different ratios of coconut chaff and peat soil were analyzed,and the suitable cultivation substrates for the growth of modular vertical greening plant were screened out,so as to provide a basis for the sustainable development of modular vertical greening.The cultivation substrates with different ratios of coconut bran and peat soil were taken as the research object.The bulk density,porosity,pH value,water absorption,alkali-decomposable nitrogen,available phosphorus and available potassium of each ratio were measured,and different ratios of substrates were applied to the modular vertical green wall to observe the growth index of Xiaoye Longchuanhua,Golden Banyan,Red Mulberry and Fujian tea.The results showed that with the increase of the proportion of peat and the decrease of the proportion of coconut bran,the porosity,pH value and water absorption of the proportioning matrix gradually increased,and the bulk density,alkali hydrolyzable nitrogen,available phosphorus and available potassium gradually increased.Golden Banyan,Red Mulberry and Fujian tea have the following magnitudes of influence on the growth of T3>T4>T2>T5>T1,T3>T2>T4>T1>T5,T3>T4>T2>T5>T1,T4>T3>T2>T5>T1.The proportion of coconut chaff+peat soil in the modular vertical greening cultivation substrate with peat soil and coconut chaff as the main raw materials should be between 60%+20% and 20%+60%.Each accounting for about 40% is the best ratio,which is more conducive to the growth of green plants.
