为探索农业废弃物基质利用新途径,将香蕉菠萝废弃茎叶堆肥与椰糠按不同比例配制成复合
基质,研究不同配比基质的理化性状、养分含量及对绿萝生长的影响。结果表明,堆肥与椰糠按(4~8)∶
(2~6)的比例(体积比)配制的基质处理容重为0.33~0.47 g/cm3,总孔隙度在80% 以上,通气孔隙度大
于17%,持水孔隙大于60%,pH 值为6.02~6.93,EC 值为0.4~1.6 mS/cm;随着堆肥添加比例增加,养分含
量大体上均呈增加趋势,有机质含量在75.8%~78.8%,碱解氮为7.3~7.6 g/kg,有效磷为0.32~0.37 g/kg,
速效钾为7.8~8.3 g/kg。不同基质对绿萝生长效果的比较试验表明,堆肥和椰糠按7∶3 比例混合的复合基
质为最佳配比基质,新生叶片数18.03 片、根系14.86 条、根重2.01 g;与对照比较,绿萝总根长增加57.98
cm,根系表面积增加22.59 cm2,根体积增加0.67 cm3,表明该配方基质可在绿萝栽培中应用。 |

In order to explore new ways of using agricultural waste matrix,the compound substrate of banana
pineapple waste leaf compost and coconut bran was prepared according to different proportions,and the effects of
different substrates with different physical and chemical properties and nutrient content on the growth of scindapsus
seedling were studied. The results showed that when the compost and coconut chaff ratio of the substrate was
(4-8) ∶(2-6),the volume weight was 0.33-0.47 g/cm3,total porosity,aeration porosity,and water-holding
porosity were higher 80%,17% and 60%,respectively,and pH and EC were 6.02-6.93 and 0.4-1.6 mS/cm,
respectively. The nutrient content increased with the proportion of compost addition. When the organic matter content
was 75.8%-78.8%,the available nitrogen,phosphorus and potassium were 7.3-7.6 g/kg,0.32-0.37 g/kg and 7.8-8.3
g/kg,respectively. Comparative test on the growth of scindapsus seedling showed that the best substrate proportion
was 7∶3( volume ratio) of compost and coconut bran,and the number of new leaf,root and root weight were 18.03,
14.86 and 2.01 g,respectively. Compared with control group,total root length,root surface area and root volume of
the treated group increased by 57.98 cm,22.59 cm2 and 0.67 cm3. These results indicated that the formula matrix
could be used as organic substrates of scindapsus seedling. |
