Study on the production of soilless turf with high humidity bamboo shavings instead of commercial peat
[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 + non-woven 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.
