温室环境对番茄生长影响的参数优化

Optimization on the Effect Parameters of Greenhouse Environment on the Growth of Tomato

以温室番茄的鲜重作为温室环境控制的目标进行决策,为温室作物生长提供经济适宜的环境参数和生长条件。重点研究了温室内番茄生长的环境参数(温度、相对湿度、光照强度)对番茄鲜重的影响规律和温室环境系统最佳参数。结果表明:影响试验指标的主要因素是温度、相对湿度、光照强度,其较优组合是温度为24℃、相对湿度为80%、光照强度为17.2klx。

Tomato is one of the major vegetables in greenhouse production.Putting maximize the tomato fresh weight as control objective.So it could create favorable microclimate parameters and conditions to fit crop growth and development.The influence of parameters of microclimate(temperature,relative humidity,light intensity)upon the tomato fresh weight and optimum parameters of microclimate system were studied in this paper.The experiment results showed that the most important factor affecting tomato fresh weight was temperature,relative humidity,light intensity.The optimized combination of factors was temperature 24℃,relative humidity 80% and light intensity 17.2 klx.
