摘要
以高级厌氧消化(热水解+厌氧消化)处理后的污泥产品为研究对象,设置污泥产品不同比例(体积比30%、40%、50%、60%、70%)与椰糠、珍珠岩、原土复配制得5种有机栽培基质,研究5种栽培基质对一串红和非洲凤仙植物株高、冠幅、生物量的影响,探讨不同种类原料何种配比组合下研发的有机栽培基质最有利于一串红和非洲凤仙植物的生长.结果显示:S3处理(污泥∶椰糠∶珍珠岩∶原土=5∶3∶1∶1)的一串红和非洲凤仙植株在生长时期的冠幅、株高、生物量高于其他处理,表明S3处理的配比基质最有利于这2种草花的生长.
Abstract
Taking the sludge products treated with advanced anaerobic digestion (thermal hydrolysis+anaerobic digestion) as the research ob-ject,five organic cultivation substrates were prepared by compounding different proportions of sludge products ( volume ratio of 30%,40%, 50%,60%,70%) with coconut bran,perlite and original soil. The effects of these five cultivation substrates on the plant height,crown width, and biomass of Salvia splendens and Impatiens walleriana were studied,the organic cultivation substrate developed under the combination of dif-ferent types of raw materials and different ratios was most beneficial for the growth of Salvia splendens and Impatiens walleriana plants.The re-sults showed that the crown width,plant height and biomass of Salvia splendens and Impatiens walleriana plants treated with S3( sludge∶coconut bran∶perlite∶native soil=5∶3∶1∶1) were higher than those of other treatments during the growth period,indicating that the substrate ratio of S3 treatment was the most favorable for the growth of these two types of flowers.
