采用4种不同有机肥配比，以大果番茄妞内姆208和樱桃番茄瑞成634为试验材料，探讨不同有机肥配比对大果番茄和樱桃番茄的生长、品质、基质酶活性与微生物数量的影响。结果表明：T2处理[草炭∶蛭石∶有机肥（颗粒）∶有机肥（粉）＝2∶1∶1∶1，体积比]可显著提高大果番茄基质中微生物数量以及脲酶、蔗糖酶、过氧化氢酶活性；t1处理[草炭∶蛭石∶有机肥（颗粒）∶有机肥（粉）＋蔗糖＝（2∶1∶1∶1，体积比）＋10 kg／m3]可显著提高樱桃番茄基质中微生物数量、脲酶以及过氧化氢酶活性。 T2处理的大果番茄和t1处理的樱桃番茄的品质较好，但T2处理的大果番茄产量较T4处理（草碳∶蛭石＝2∶1，体积比）大果番茄产量低，t1处理的樱桃番茄产量较t4处理（草碳∶蛭石＝2∶1，体积比）的樱桃番茄产量低。因此，大果番茄采用T2处理、樱桃番茄采用t1处理可改善基质环境，提高番茄品质。%Common tomato Nunhems 208 and cherry tomato Ruicheng 634 were chosen as materials to study the effects of different combinations of organic fertilizers on substrate microorganism, substrate enzymes and quality of tomato. The combination of T2( peat ∶ vermiculite ∶ granular organic fertilizer ∶ powdery organic fertilizer=2 ∶ 1 ∶ 1 ∶ 1 volume rati⁃o) significantly increased the quantity of microorganisms, activities of enzymes, including sucrase, urease and catalase, and the quality of common tomato. The combination of t1( peat ∶ vermiculite ∶ granular organic fertilizer: powdery organic fertilizer sucrose = (2 ∶ 1 ∶ 1 ∶ 1) +10 kg/m3 ) significantly elevated the quantity of microorganisms, activities of phosphatase and catalase, and the quality of cherry tomato. Common tomato yielded less by fertilization combination T2 than that by combination T4, and cherry tomato yielded less by combination t1 than that by combination t4. To summary, fertili⁃zation combination T2 for common tomato and combination t1 for cherry tomato are favorable for improving substrate environ⁃ment and tomato quality.
