关于大棚番茄高产栽培的光热水条件的研究,本课题组曾于1977～1978年对北京郊区大棚番茄亩产2～3万斤的高产典型进行过调查,将所收集的资料用计算机进行多元回归分析,得出了影响大棚番茄产量丰歉的光、热、水管理指标,在生产中应用取得较好效果. 在此基础上,本文用1988年本所试验站大棚栽培试验资料,进一步研究一天中的不同时段即上午、下午、前半夜、后半夜的棚温对番茄产量的影响,并分别对座果期、果实迅速膨大期和红熟期进行分析研究,为大棚番茄的四段变温管理提供科学依据.(分析方法略).
On the tomato greenhouse cultivation of light and hot water conditions, our group had in 1977 ~ 1978 on the suburbs of Beijing suburbs tomato per mu yield of 2 to 3 million pounds were investigated for high yield, the data collected by the computer multi-element Through regression analysis, we got the index of light, heat and water management that affect the yield of tomato in greenhouse and achieved good results in the application of production.On the basis of this, we use the test data of greenhouse cultivation in our laboratory in 1988 to further study The effects of greenhouse temperature on tomato yield at different times of the day, ie, morning, afternoon, midnight and midnight, were analyzed respectively. The results showed that the fruit temperature, Management provides a scientific basis (analysis method omitted).
