摘　　要：【目的】探究不同茄果类蔬菜秸秆对毛桃幼苗养分吸收的影响。【方法】通过盆栽试验,研究了4种茄果类蔬菜茄子(Solanum melongena)、番茄(Solanum lycopersicum)、土豆(Solanum tuberosum)和辣椒(Capsicum annuum)秸秆对毛桃(Prunus davidiana)幼苗养分吸收的影响。【结果】茄子秸秆处理的毛桃幼苗根系和地上部分的生物量较对照增加了8.33%和17.36%,其余处理对毛桃幼苗生物量影响不显著或具有降低作用。辣椒秸秆处理提高了毛桃幼苗全氮含量,使其根系和地上部分全氮含量分别较对照增加了5.64%和13.63%,其余3种秸秆处理对毛桃幼苗全氮含量影响不显著或起降低作用。施用土豆秸秆的毛桃幼苗磷转运能力最高,使其根系和地上部分全磷含量分别较对照增加了26.45%和34.68%,其余处理降低了毛桃幼苗全磷含量或对其无显著影响。4种秸秆处理均能提高毛桃幼苗全钾含量。辣椒秸秆处理在一定程度上提高了毛桃幼苗氮、磷和钾吸收和转运能力,其余3种秸秆处理只对某一种元素的吸收和转运能力起促进作用。【结论】施用4种茄果类蔬菜秸秆均能够在一定程度上促进毛桃幼苗对养分的吸收和转运,其中以辣椒秸秆效果最佳。[Objective]The study investigated the effects of different solanaceous vegetable straws on the nutrient absorption of peach seedlings.[Method]A pot experiment was conducted to figure out the effects of four solanaceous vegetable straws on eggplant(Solanum melongena),tomato(Solanum lycopersicum),potato(Solanum tuberosum)and pepper(Capsicum annuum)straw on nutrient absorption of peach(Prunus davidiana)seedlings.[Result]The biomass of the roots and above-ground parts of peach seedlings treated with eggplant straw increased by 8.33%and 17.36%compared with the control.The other four straw treatments had no significant effect on the biomass of peach seedlings.The pepper straw treatment increased the total nitrogen content of peach seedlings,and the total nitrogen content of the roots and aboveground parts increased by 5.64%and 13.63%compared with the control.The other three straw treatments had no significant effect on the total nitrogen content of peach seedlings.The phosphorus transport ability of peach seedlings treated with potato straw was the highest,and the total phosphorus content in the root system and aboveground parts increased by 26.45%and 34.68%compared with the control.The remaining three straw treatments reduced the total phosphorus content of the peach seedlings or had no significant effect.All four straw treatments could increase the total potassium content of peach seedlings.The pepper straw treatment improved the nitrogen,phosphorus and potassium absorption and transport capacity of peach seedlings to a certain extent,while the other three straw treatments only promoted the absorption and transport capacity of a certain element.[Conclusion]All four types of solanaceous vegetable straws could promote the absorption and transport of nutrients by peach seedlings to a certain extent,among which pepper straw had the best effect.
