摘要
采用椰纤、腐叶土、松针等有机废弃物与草炭进行红掌栽培基质配比,从基质理化性状及生物学性状方面,探讨不同基质配比对红掌中、小苗生长的影响。从经济性、实用性、节约资源、保护环境出发,优选出盆栽红掌适宜基质配方及适宜基质理化指标以替代进口基质。结果表明:以国产草炭(GC)为主要原料与椰纤、腐叶土、松针、陶粒等有机废弃物进行复配的基质配方完全可以替代进口泥炭。优选出红掌小苗基质配方2个:L2(GC 60%+椰纤40%);L5(GC 70%+腐叶土30%)。红掌中苗基质配方3个:B2(GC50%+椰纤50%),B5(GC 50%+松针50%),B8(GC 80%+大陶粒20%)。并确定了盆栽红掌基质适宜理化指标:容重0.24~0.26 g/cm3,总孔隙度60%~70%,气水比0.15~0.17,pH值5.5~6.5,EC值小于500μS/cm为宜。
Culture substrate pot experiments were carried out to value the effects on physical and chemical properties of substrate and biological properties of under different ratios of coir,humus,pinetree needles and domestically-produced peat.Two height levels of small plants were selected in the study,10 cm and 20 cm,with the imported peat material as the control.The results showed that the domestically-produced peat with coir,ceramic,humus and pine needles had the potential to replace the imported peat.2 formulas for 10 cm plants and 3 formulas for 20 cm plants were selected from the experiments.L2(GC 60%+coconut fiber 40%),L5(GC 70%+artificial humic substance 30%)for the appropriate formula,B2(GC50%+coconut fiber 50%),B5(GC 50%+Lecanosticta 50%),B8(GC80%+bark 20%).The physical and chemical indicators matrix were as follows:bulk density in 0.24~0.26 g/cm3,total porosity 60%~70%,gas-water ratio 0.15~0.17,pH at 5.5~6.5 and EC values of less than 500 μS/cm were appropriate.
