Study on formula selection and production process of compressed cultivation matric based on green plant waste compost
摘要
Abstract
[Objective]This research delved into optimizing the production conditions of compressed cultiva-tion matric using green plant waste compost to bolster its physical and chemical attributes.[Method]The matric fabrication involved thermo-compression with green compost and peat as the primary components,supplemented by a superabsorbent polymer,and additionally,wood adhesive powder was added as a curing agent.Through single fac-tors and orthogonal analysis experiments,the optimal parameters for the molding agent were determined.The result-ing matric was evaluated through a comprehensive analysis of its physical and chemical properties,TOPSIS assess-ment and alfalfa cultivation experiments.[Result]Findings revealed the ideal composition to be 59%green compost and peat(in a volume ratio of 6∶4),30%perlite,1%potassium polyacrylate superabsorbent polymer,and 10%wood adhesive powder,with water added to achieve 50%moisture content.Thermo-compression conditions were optimized with a compression density of 0.5 g·cm-3,molding temperature of 105℃,and after being pressed into the mold,the substrate blocks were heated for 25 min in an oven at 105 ℃,then cooled for 15 min,and demolded at room tempera-ture storage for 24 h.Under these conditions,the bulk density of the cultivation substrate blocks was 0.51 g·cm-3,the total porosity was 47.15%,the ratio of large to small pores was 1∶3.33,the abrasion loss rate was 7.35%,the expan-sion coefficient was 125.23%,the initial water absorption rate was 90.70%,and the water retention rate decreased by 61%after 72 h.TOPSIS analysis ranked the matrics as CK>T6>T9>T4>T1>T3>T8>T2>T5>T7 based on a com-prehensive evaluation of the aforementioned indicators.Apart from T6,the substrates in the treatments of T9,T4 and T1 were similar to the physical and chemical properties of the control straw-based compressed substrate blocks,and could be considered for using as cultivation substrates.Among the treatments,T2 showcased superior performance in alfalfa cultivation,followed by T1 and T4.By mixing and compacting green compost with materials such as peat to create cultivation substrate blocks,the resulting blocks had good physical and chemical properties suitable for the seedling cultivation of alfalfa.[Conclusion]This substrate block formula is economical,easy to produce,and con-venient to use,which is of significant importance for the development of composted garden waste cultivation sub-strate blocks in China and the promotion of soilless cultivation technology.关键词
