| 摘 要： | 利用人工气候室，研究了空气湿度对高温下番茄开花坐果的影响。试验设置2个空气相对湿度处理，即70%±5%（高湿处理）和不加湿（低湿处理，作为对照）。结果表明，在10:00至16:00平均温度为36.5℃的高温条件下，55%的低湿处理造成植株营养不良和花蕾灼伤，使落蕾率增加，开花较少，坐果率较低；而70%的高湿处理，改善了植株的营养条件，减少了花蕾灼伤，使开花率提高了27% ~ 34%，坐果率提高了26% ~ 30%。表明在36.5 ℃的高温条件下，70%的相对湿度有利于番茄开花坐果。

| Abstract: | The effects of air relative humidity （RH） on the flowering and fruit-setting of tomato under high temperature were investigated in growth chambers.Two relative humidity treatments of 70% ± 5% （high RH） and non-humidification （low RH,as control） were set from 10：00 to 16：00 at the average temperature of 36.5 ℃.The results showed that relative humidity up to 70%,rate of flower blooming and fruit set were improved by 27%～34% and 26%～30%,respectively,which resulted from enhanced carbohydrate supply and decreased burned-flower buds.As a conclusion,relative humidity of 70% （high RH） was fit for flowering and fruit-set of tomato under high temperature of 36.5 ℃. |
