园林废弃物堆肥用于青苹果竹芋栽培研究

Application of green waste compost for Calathca rotundifola cv.Fasciata cultivation

为减少花卉无土栽培对泥炭资源的依赖和提高园林废弃物的再利用率,以泥炭和园林废弃物为原材料,通过使用品氏泥炭(Y)、炭化园林废弃物(TY)、堆置园林废弃物(DZ)、泥炭+炭化园林废弃物(Y+TY)、泥炭+堆置园林废弃物(Y+DZ)、泥炭+炭化园林废弃物+堆置园林废弃物(Y+TY+DZ)6种基质来栽培青苹果竹芋,探讨园林废弃物堆肥替代泥炭作为青苹果竹芋栽培基质的可行性。通过对青苹果竹芋总鲜质量、根鲜质量、叶鲜质量、烘干总质量、烘干根质量、烘干叶质量、冠幅、发枝数、株高和根长10项生长指标进行测定与分析,得出6种基质对青苹果竹芋生长促进作用由大到小依次是:Y+DZ>Y+TY>DZ>Y>Y+TY+DZ>TY。可知经一定处理及配比的堆置园林废弃物能够全部或部分替代进口泥炭进行青苹果竹芋栽培,且其中有3个处理均优于原有泥炭处理,对青苹果竹芋生长具有明显的促进作用,可作为青苹果竹芋无土栽培的代用基质。

In order to reduce the dependence of soilless culture of flowers on peat and increase the recycling rate of green waste,we made a research to assess the feasibility of green waste composting replacing the peat as growing media.By using peat and green waste as raw materials,we utilized six kinds of growing media,including peat（Y）,carbonized green waste（TY）,composting（DZ）,peat＋carbonized green waste（Y＋TY）,peat＋composting（Y＋DZ）,peat＋carbonized green waste＋composting（Y＋TY＋DZ） to cultivate Calathca rotundifola cv.Fasciata.Through measuring and analyzing ten growth indexes,ie total fresh weight,fresh root weight,fresh leaf weight,total dry weight,dry root weight,dry leaf weight,total crown,branching number,plant height and root length,we could get the results of positive effects of six kinds of growing media on the cultivation of C.rotundifola cv.Fasciata and the rank order was Y＋DZ〉Y＋TY〉DZY〉Y＋TY＋DZ〉TY.It can be seen that green waste composting undertaken a certain treatment can replace all or part of the original imported peat to cultivate C.rotundifola cv.Fasciata,and three of the six treatments were better than the original peat.The growth of C.rotundifola cv.Fasciata was promoted after using three kinds of growing media.Thus,the green waste could be treated as an excellent growing media to the soilless culture of C.rotundifola cv.Fasciata.
