摘　　要：将污泥、梧桐落叶、潮土和尿素4种材料以不同比例进行堆肥,腐熟后与土壤配制成9种栽培基质,种植油菜,研究其对油菜幼苗生长发育的影响,以筛选出适合油菜出苗和生长的堆肥。结果表明:4种不同材料按不同比例配制发酵的堆肥对油菜发芽和生长影响不同,综合发芽率、出苗率、苗和根的鲜干重情况等指标得出,E处理即采用1 000 g落叶配合800 g污泥、600 g土壤以及20 g尿素进行堆肥的效果最好,而C处理即1 000 g落叶配合1 200 g污泥、600 g土壤以及20 g尿素进行堆肥的效果最差;9种不同材料按不同比例配制发酵的堆肥对油菜出苗及生长促进作用由好到差的排列顺序依次是:E、D、B、A、H、F、G、C、I。结果表明,园林废弃物所得堆肥产品可作为植物生长的基质并且可以部分替代稀缺资源泥炭。By indoor pot experiment, the writer takes use of sludge, leaves, soil and urea these four kinds of materials in different proportions formulated into 9 kinds of growing media, studied its effect on the growth of rape seedlings to filter out for rapeseed cultivation matrix type and ratio, while also providing the scientific basis for reasonable garden waste recycling in plant cultivation. The best one was E, which was 1 000 g leaves, 800 g sludge, 600 g soil and 20 g urea. while the worst one was 1 000 g leaves, 1 200 g sludge, 600 g soil and 20 g urea. Through the analysis of rape seedling germination rate, fresh and dry weight, plant height and root length and other morphological indexes, observed that the descending order of 9 matrix which can promote growth of oilseed rape are E, D, B, A, H, F, G, C, I, respectively. This studies show that this kind of fertilizer can be the culture for plants and can partly substitute for scarce peat resources.
