摘　　要：以猪粪堆肥为原料,设置高氮、高磷和高钾的有机无机复混(散混)肥处理,以及分2次施用的高氮处理和颗粒态高氮处理,研究了这些不同养分配比和施肥方式对盆栽条件下樱桃番茄生长状况、产量和维生素C、硝酸盐及可溶性糖含量等品质的影响。结果表明,施磷量为每千克土P2O50.2g的各肥料处理,樱桃番茄幼苗的生长受到磷营养不足的抑制,施磷量为每千克土P2O50.3g的高磷处理幼苗生长良好,各处理在每千克土追施P2O50.1g后磷的限制作用得以解除;在不同养分配比及不同施用方式中,高钾处理(每千克土N0.2gP2O5-0.3g-K2O0.3g)和在苗期、初果期分2次施用的高氮处理(每千克土N0.3g-P2O50.3g-K2O0.2g)取得了产量和品质俱佳的效果,即在保证土壤不缺磷的条件下,增施钾肥和分2次施用氮肥,盆栽樱桃番茄可获得优质高产。The growth status,yield and quality of mini-tomato,including the content of vitamin C, nitrate,and soluble sugar under different organic-inorganic compound fertilizer treatments were investigated. Treatments include high nitrogen, high phosphorus, high potassium, and high nitrogen fertilized twice and fertilized in granular form. The results indicated that the growth of mini-tomato seedling was repressetl to some extent when phosphorus application amount was P2 O5 0. 2 g/kg soil in the .fertilizer, but the seedling growth was not inhibited when the phosphorus application amount was P2O50.3 g/kg soil after adding P2O5 0. 1 g/kg for each fertilizer, the restriction of phosphorus was alleviated. In the 5 kinds of organic inorganic mixed fertilizers, the high nitrogen treatment applied in seedling stage and primary fruit stage,respectively,the highest yield and the best quality was gained, and the high potassium treatment ranked the second. It suggested that increasing nitrogen and potassium content of the fertilizer to some extent and applied twice with no phosphorus limit, were helpful to obtain best effect in both yield and quality in the pot experiment of mini-tomato.
