研究了不同类型土壤改良剂对番茄果实采后品质的影响。土壤改良剂分别是250 kg/hm2的NPK15-15+250 kg/hm2的阿苏拉可可肥(NPK0-22-18+9CaO+6S+5MgO(S))、250 kg/hm2的NPK15-15-15加硫铵(125 kg/hm2)、家禽粪便(1.1 kg/m2)和对照(不改良剂)。在平均温度为26.85℃、相对湿度为85.75%的条件下，对粉红期番茄果实贮藏7天后的品质性状进行了评价。果实品质性状包括果实失重率、硬度、外观、膜离子渗漏、果皮厚度、腐烂、可溶性固形物、果皮重量、干物质、水分含量和货架期。土壤改良剂(P<；0.002)对果实品质性状的影响差异显著。施NPK+‘Asasewura’可可肥处理的果实，其失重率、膜离子渗漏腐烂和水分含量均低于施NPK+硫铵、鸡粪和对照的处理，果实硬度、外观、可溶性固形物、干物质和货架期均高于NPK+硫铵处理和对照。果实失重率与硬度(-0.71)和货架期(-0.71)呈显著负相关，膜离子渗漏(0.63)和腐烂(0.57)呈显著正相关。果皮厚度与果形(0.69)、果皮重量(0.68)、可溶性固形物(0.73)呈显著正相关。

The experiment was conducted to test the influence of different soil amendments types on postharvest performance of tomato fruits. The soil amendments were NPK 15-15-15 at 250kg/ha plus ‘Asasewura’ cocoa fertilizer (NPK 0-22-18 + 9CaO + 6s + 5MgO(s) at (250kg/ha), NPK 15-15-15 at 250kg/ha plus sulphate of ammonia (125kg/ha), poultry manure (1.1kg/ m²) and control (no amendment). Selected quality traits of tomato fruits harvested at the pink colour stage were evaluated after seven (7) days storage under average temperatures of 26.85°C and relative humidity of 85.75%. Fruit quality traits studied were fruit weight loss, firmness, general appearance, membrane ion leakage, pericarp thickness, decay, total soluble solids, pericarp weight, dry matter, moisture content and fruit shelf life. Significant differences among the soil amendments (P < 0.002) were observed in fruit quality traits studied. Fruits harvested from soil amended with NPK plus ‘Asasewura’ cocoa fertilizer recorded lower in weight loss, membrane ion leakage decay and moisture content and higher fruit firmness, general appearance, total soluble solids, dry matter and shelf life than fruits harvested from fields amended with NPK plus Sulphate of ammonia, Poultry manure and Control respectively. Significant correlations (P < 0.01 and P < 0.05) were observed among the quality traits evaluated. Fruit weight loss showed significantly but negative correlation between fruit firmness (-0.71) and shelf life (-0.71) but indicated significant but positive correlation between membrane ion leakage (0.63) and fruit decay (0.57) respectively. Fruit pericarp thickness showed significant but positive correlation between general appearance (0.69), pericarp weight (0.68) and total soluble solids (0.73).
