在实验室采用浓度为0.5～2.5克/升的苯来特溶液,浸渍处理4个品种番石榴,果实腐烂明显减少。最适浸渍药液温度为48～50℃,浸渍5分钟。用50℃的双■盐溶液,浓度0.5克/升,浸渍5分钟,也能减少果腐,但效果较苯来特差且较易导致果皮损伤,热水浸渍果实也有减少果腐的效果,但不及苯来特和双■盐的好。 In the laboratory using the concentration of 0.5 to 2.5 grams / liter of benzene solution, immersion treatment of four varieties of guava, fruit decay was significantly reduced. The optimum temperature for immersion liquid is 48 ~ 50 ℃, soak for 5 minutes. With 50 ℃ double salt solution, the concentration of 0.5 g / l, soaked for 5 minutes, can also reduce fruit rot, but the effect is worse than benzene and is more likely to cause damage to the peel, hot water immersion fruits also reduce fruit rot effect, But not as good as benzene and double salt ■ salt.
