高湿竹屑替代商品草炭生产无土草坪的研究

Study on the production of soilless turf with high humidity bamboo shavings instead of commercial peat

【目的】开发替代商品草炭的无土草坪栽培基质,减少草坪生产中耕地的破坏以及资源消耗,降低生产成本,并实现竹材废弃物资源化利用。【方法】将新鲜竹屑(含水量60%)分别进行堆贮处理和堆肥处理,分析其理化性质,再进行草坪栽培试验,设置6个处理:CK1(草炭)、CK2(草炭+无纺布)、A1(堆贮竹屑)、A2(堆贮竹屑+无纺布)、B1(堆肥竹屑)、B2(堆肥竹屑+无纺布);进一步设置草炭与堆贮竹屑的不同混合体积比:100∶0、75∶25、50∶50、25∶75、0∶100,进行黑麦草栽培试验,观测草坪草生长情况及草坪综合质量。【结果】堆贮竹屑比堆肥处理的更适合用作草坪栽培基料,配合使用无纺布可提升草皮成卷率。商品草炭与堆贮竹屑体积比50∶50的草坪质量评分更高。【结论】堆贮竹屑可替代50%的商品草炭进行草坪无土栽培,有利于草坪草生长,并可节约资源,有效降低生产成本。

【Objective】The aim of the study is to develop a kind of soilless turf culture media which could replace commercial peat,reduce the damage of cultivated land and resource consumption,reduce the production cost,and real⁃ize the resource utilization of bamboo waste.【Method】Fresh high moisture bamboo shavings(60%water content)were treated by pack-ensilaging and compost methods,and their physical and chemical traits were analyzed.Six treatments were set:CK1(peat),CK2(peat+non-woven fabric),A1(ensilage bamboo shavings),A2(ensilage bamboo shavings+non-woven fabric),B1(compost bamboo shavings),B2(compost bamboo shavings+nonwoven fabric).Then different mixed volume ratios of peat and ensilage bamboo shavings were set:100∶0,75∶25,50∶50,25∶75,0∶100.The experiment of ryegrass cultivation was carried out to observe the growth of turf grass and the comprehensive quality of turf.【Result】The results showed that the ensilage bamboo shavings were more suitable to be used as the base material for turf cultivation than the ones treated with compost,and the roll⁃up rate of turf could be increased by using non⁃woven fabric.The turf grass growth and turf grass comprehensive quality score showed that the turf grass quality scores of the treatments using whole commercial peat and commercial peat:ensilage bam⁃boo shavings volume 50:50 were better than other treatments.【Conclusion】Ensilage bamboo shavings could replace 50%commercial peat for turf soilless culture,which was beneficial to turf grass growth,and could also save resources and reduce production cost effectively.
