Abstract

Abstract: Taking tomato variety “Ouguan” as test material, this paper analyzed the daily variation rule of water consumption and tomato daily water consumption in glasshouse under rock wool nutrient solution cultivation system and typical weather conditions in different growth periods; and carried out correlation analysis on environmental factors and tomato water consumption in greenhouse. The results showed that at noon(around 14:00) greenhouse tomato would take a midday rest when tomato water consumption rate showed a bimodal curve; but the exorbitant temperature inside of greenhouse and too strong light would stop tomato plant lunch break, and water consumption would maintain at a high level. The tomato water consumption had a significant correlation with indoor temperature and light in the greenhouse. The changing rule of water consumption was consistent with the trend of light changing rule in the greenhouse, but it had certain hysteresis quality. Above results provided guidance for high-frequency precise irrigation of greenhouse rock-cultivated tomato and also reference data for automatic greenhouse tomato irrigation.

Key words: greenhouse, tomato, rock wool nutrient solution cultivation system, water consumption rule, high-frequency precise irrigation

摘要： 以粉果番茄“欧官”为试验材料，对不同生育期内典型天气条件下温室岩棉营养液栽培番茄的耗水日变化规律及番茄日耗水量进行了分析，并对温室内环境因子与番茄耗水量进行了相关性分析。结果表明：温室番茄在午间（14:00左右）会出现午休现象，即番茄耗水速率呈现双峰曲线；但室内温度过高、光照过强会打破番茄午休现象，耗水一直维持较高的水平。番茄耗水量与温室内温度、光照具有极显著的相关性，耗水变化规律与温室内光照变化规律一致，并具有一定的滞后性。上述结果可为温室岩棉营养液栽培番茄的高频率精准灌溉提供指导，为温室番茄自动灌溉提供依据。
