辽沈系列不同构型育苗温室环境对秧苗质量影响的比较研究

根据辽沈I型7.5 m、10 m跨度及7.5 m半地下式育苗温室不同位点环境条件对番茄穴盘苗指标影响的研究比较,分析这3种构型温室适宜繁育秧苗的优劣程度。结果表明,相同构型不同跨度育苗温室间,大跨度环境更为有利于缩小南北向不同位点的秧苗质量差异;相同跨度不同构型间,半地下式设计可促进均一性较高秧苗的培育。因而,在育苗温室的构型设计上,应有意识的趋向于大跨度与半地下式。

Effects of Microclimatic Conditions in Different Construction of Liaoshen Type Seedling Greenhouse on Seedling Quality

The comparative research was carried out to study the effects of different positions of the three seedling greenhouses on the tomato plug seedling indexes,and their performances of raising seedlings were analyzed.The three seedling greenhouse were Liaoshen type I seedling greenhouse with span of 7.5 m,10 m and the semi-underground seedling greenhouse with span of 7.5 m,and the five equal positions were marked as T1,T2,T3,T4,T5 from the south to the north.The results showed that the long-span seedling greenhouses were beneficial to reduce seedling differences among the greenhouses with the same configuration,and the semi-underground seedling greenhouse was suitable for raising uniform seedlings among the greenhouses with the same span.In all,the long-span and semi-underground seedling greenhouses should be taken in designing the construction of seedling greenhouse.
