| 摘 要： | 在控根容器春提前番茄栽培条件下,研究了苗期、初花期和结果期不同土壤水分条件下番茄的耗水量、产量、水分生产效率、产量与水分之间的函数关系以及水分调控对产量形成过程和形态生理指标的影响.结果表明:苗期、初花期和结果期的土壤水分分别保持在60%～95%、70%～90%和85%～90%时可实现高产、高效;番茄总产量与总耗水量之间呈二次抛物线关系,最佳灌水量为3 560.98m3/hm2;苗期水分过低不利于番茄果实的提早成熟,初花期水分亏缺使获得阶段产量最大值的时间延后,结果期水分亏缺使后期产量明显降低;在结果期,土壤水分亏缺影响更多的是表现在产量方面,形态指标差异不明显;土壤水分亏缺给植株带来较高光合速率和较高蒸腾速率,不利于有机物质形成.

| Abstract: | In this experiment,tomato plants were grown in root-controlling containers to study the effects of different soil moistures at the seedling stage,the initial bloom stage and the fruit-bearing stage on their water consumption,yield,water use efficiency,water production function,yield formation process and morphological and physiological indexes.The results showed that the optimal range of soil moisture,expressed as percent of the field capacity,was 60%~95% for the seedling stage;70%~90% for the initial bloom stage and 85%~90% for the fruit-bearing stage.The relationship between total yield and total amount of water consumption was quadratic parabola,and the optimal irrigation rate was 3 560.98 m3/hm2.Low soil moisture at the seedling stage was unfavorable for their early maturation.Water deficit at the initial bloom stage postponed the date of greatest yield,and low soil moisture at the fruit-bearing stage brought about lower yield in the later stage.Water deficit at the fruit-bearing stage mainly affected yield of the crop but had no significant effect on the morphological indexes.Water deficit resulted in relatively high photosynthetic rate and transpiration rate,which was unfavorable to the synthesis of organic matter. |
