【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]:The application of fertilizer can affect the decomposition of organic fertilizer and the process of nutrient release, and the varieties of different crops have different nutrient requirements. The earthworm excrement is a new type of alternative fertilizer which can improve the soil and promote the growth of the plant. The effects of the application of vermis on the growth and soil fertility of different tomato varieties were studied by pot experiment. The pot experiments were as follows: two kinds of tomato varieties: Jinshang3 and Eel;4 kinds of fertilization methods: single application of chemical fertilizer (CF); and the application of vermis (VS). Namely, the earthworm dung is mixed with the upper 8-cm-thick soil in the upper part of the pot bowl, and the earthworm dung is applied (VL), namely, the vermis dung is uniformly distributed under the position of 8 cm, and the vermis is mixed with the soil (VM), that is, the earthworm excrement is mixed with all the soil. The results showed that the biomass of the stem and leaf of the tomato can be increased and the absorption of nitrogen and potassium can be promoted as compared with that of the whole soil, and the effect of the vermis is more dependent on the mode of application as compared with the single-application fertilizer. The soil pH and the organic carbon content can be improved by the application of the vermis and the mixed application of the whole soil. In the flowering stage, the content of available P and available K in the soil is the highest at the time of application of the vermis, while the effective phosphorus content of the soil and the whole soil is higher than that of the medium. Compared with the application of the soil and the whole soil in the vermis, the soil mineral nitrogen content of the Ariel was reduced. In conclusion, the concentrated application of vermis can promote the growth of tomato and the absorption of nutrients, and the effect is consistent among different varieties.
