| 摘 要： | 肥料的施用方式会影响有机肥料的分解和养分释放过程,且不同作物品种在养分需求方面也各有差异。蚓粪是一种能够改善土壤和促进植物生长的新型替代肥料。采用盆栽试验研究了蚓粪施用方式对不同番茄品种生长和土壤肥力的影响,盆栽试验设置为:两个番茄品种:金棚三号和艾瑞尔;4种施肥方式:单施化肥(CF);蚓粪表施(VS),即蚓粪与盆钵上部8 cm厚土壤混施;蚓粪中施(VL),即蚓粪均匀平铺紧邻8 cm处下方;蚓粪全土混施(VM),即蚓粪与所有土壤混合。结果表明:相比全土混施,蚓粪表施和中施更能增加番茄的茎叶生物量并且促进其对氮、钾的吸收;与单施化肥相比,蚓粪的效果更依赖于施用方式,蚓粪表施和全土混施比中施更能提高土壤pH和有机碳含量。在盛花期,无论番茄品种,土壤有效磷、速效钾含量都在蚓粪表施时最高;而在收获期,蚓粪表施和全土混施的有效磷含量高于中施处理。相比蚓粪中施和全土混施,表施降低了艾瑞尔的土壤矿质氮含量。总之,蚓粪的集中施用如表施和中施,能促进番茄生长及养分吸收,并且在不同品种之间效应一致。

| Abstract: | Application method affects the processes of decomposition and nutrient release of organic amendments, and moreover different crop cultivars varies in terms of growth and nutrient requirements. Vermicompost is a new kind of alternative fertilizers to promote soil quality and plant growth. A pot experiment was conducted to explore the effects of vermicompost application (including VS, vermicompost mixed evenly with topsoil above 8 cm depth; VL, vermicompost applied evenly just below 8 cm depth; VM, vermicompost mixed evenly with total soil) on the growth of two tomato cultivars (Jin Peng and Ai Ruier) and on soil fertility. The results showed that VS and VL increased shoot biomass and promoted nutrient uptakes including nitrogen, phosphorus and potassium. Compared with chemical fertilizer only (CF), vermicompost effect was dependent on application method, VS and VM increased more soil pH and organic carbon content than VL. At blooming stage, soil available phosphorus and potassium were highest under VS regardless of tomato cultivars. At harvesting stage, soil available phosphorus content was least under VL compared with VS and VM. VS decreased soil mineral nitrogen content for the cultivar of Ai Ruier compared with VL and VM. In summary, vermicompost applies intensively in soil such as VS and VL can promote tomato growth and nutrient uptake, and such effect is consistent between different tomato cultivars. |
