【摘要】：肥料的施用方式會(huì)影響有機(jī)肥料的分解和養(yǎng)分釋放過(guò)程,且不同作物品種在養(yǎng)分需求方面也各有差異。蚓糞是一種能夠改善土壤和促進(jìn)植物生長(zhǎng)的新型替代肥料。采用盆栽試驗(yàn)研究了蚓糞施用方式對(duì)不同番茄品種生長(zhǎng)和土壤肥力的影響,盆栽試驗(yàn)設(shè)置為:兩個(gè)番茄品種:金棚三號(hào)和艾瑞爾;4種施肥方式:單施化肥(CF);蚓糞表施(VS),即蚓糞與盆缽上部8 cm厚土壤混施;蚓糞中施(VL),即蚓糞均勻平鋪緊鄰8 cm處下方;蚓糞全土混施(VM),即蚓糞與所有土壤混合。結(jié)果表明:相比全土混施,蚓糞表施和中施更能增加番茄的莖葉生物量并且促進(jìn)其對(duì)氮、鉀的吸收;與單施化肥相比,蚓糞的效果更依賴于施用方式,蚓糞表施和全土混施比中施更能提高土壤pH和有機(jī)碳含量。在盛花期,無(wú)論番茄品種,土壤有效磷、速效鉀含量都在蚓糞表施時(shí)最高;而在收獲期,蚓糞表施和全土混施的有效磷含量高于中施處理。相比蚓糞中施和全土混施,表施降低了艾瑞爾的土壤礦質(zhì)氮含量�？傊�,蚓糞的集中施用如表施和中施,能促進(jìn)番茄生長(zhǎng)及養(yǎng)分吸收,并且在不同品種之間效應(yīng)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.
