自控温室气象条件对番茄产量的影响

Effect of meteorological conditions in self-controlled greenhouse on the yield of tomato.

对大型玻璃自控温室种植2年的番茄产量序列与气象条件进行相关分析。结果表明,在上海地区气候条件下影响大型玻璃自控温室番茄生产的关键气象因子是光强、温度日较差和相对湿度,它们与产量的相关系数分别为0.563、0.449和0.505,相关性极显著,为改善玻璃自控温室的生产调控措施提供理论依据。

The environment conditions and managements of fertilizer and water in Holland green house which was recommended by Shanghai were controlled by computer. Based on two years' yield data of tomato and meteorological conditions, the relevant analysis was done. The results showed that the main factors influencing the tomato yield are irradiation, temperature difference and relative humidity under Shanghai weather conditions. It will help to improve modulation mea-sures.
