冷害是影响上海秋番茄贮藏的主要原因。采用空气加温电热线控温加温,控制温度下限(10℃),保持室温在10—14℃,可完全避免冷害。应用厚度为0.04mm并以大号缝衣针(7/0号针)打有一定数目小孔的聚乙烯薄膜密封。使帐内的CO_2浓度控制在3—6％,即能有效地延缓绿熟番茄的后熟,并延长其贮藏期.CO_2浓度过高会产生生理伤害.3.7—7.3％的CO_2浓度会加重冷害和腐烂。对冷害和CO_2伤害的症状作了阐述。根据上述结果,提出了秋番茄产地简易自发气调贮藏技术,经多点生产性试验表明,贮藏45天以上,好果率达80％,商品率近90％,果实品质良好。
Chilling injury is the main reason for affecting autumn tomato storage in Shanghai. Air heating electric heating temperature control, the lower limit of temperature control (10 ℃), to maintain room temperature at 10-14 ℃, can be completely cold damage. Use a polyethylene film with a thickness of 0.04 mm and pinned with a number of small holes on a large sewing needle (needle 7/0). So that the account of CO_2 concentration control 3-6%, which can effectively delay green ripe tomato ripening, and extend its storage period.CO_2 concentration is too high will have physiological damage.3.7-7.3% CO 2 concentration will increase the chilling injury And decay. The symptoms of chilling injury and CO 2 injury were described. According to the above results, a simple spontaneous atmosphere storage technique of autumn tomato was proposed. After more than 45 days of storage, good fruit rate reached 80%, commodity rate nearly 90% and fruit quality was good.
