摘要
包头市杨、柳、槐等落叶阔叶城市园林树种枯落叶腐熟堆肥理化性状和毒性测定及其盆栽四季海棠试验结果表明,城市枯落叶堆肥GI值/%为97.49%,没有毒性,腐熟合格;C/N比为23,符合堆肥标准;pH值7.17,微碱性;EC值2.13us·cm-1,有机质含量42.26%,符合国家肥料有机质含量标准;全N、全P、全K含量分别是2.04%、1.80%、0.75%,以枯落叶堆肥为主(100%或70%)的盆栽基质培育的四季海棠在株高、冠幅、叶片数、花朵数、根系长、根数等显著优于其他处理(p<0.05),枯落叶堆肥可以用作盆栽基质材料。
The fallen leaves of Populous and Robinia were composted. The compost mixed with soil were applied as the medium to Begonia senzperflorens cultivation. The data were processed by Grey Correlation Analysis and the result showed that compost amounts 30% or above would improve the flower crown and leaves.
