中文摘要:本文根据1972—73年在江苏省洪泽县进行水浮莲越冬保苗试验时观测的资料讨论了越冬温床的微气候特点,比较了塑料薄膜温床及玻璃温床的短波辐射平衡,给出了确定酿热物的发热率、导温率及酿热物中热通量的计算方法和计算结果,对温床内热量平衡方程中其余各项也进行了讨论。根据观测研究的结果文中对水浮莲越冬温床的结构及管理措施提出了一些建议。
 
Microclimatic Characteristics of Hotbeds in Winter Months
Abstract:Experiments were carried out in Hongze county, Jiangsu province, for pistia stratiotes shoot protection in the cold months of 1972-1978, Based on the experimental data some mieroclimatic characteristics of hotbeds are examined in this paper. Short wave radiation balances of both hotbeds with plastic filmy cover and those with glass cover are compared. Calculation methods and thus the results are produced for the determination of the heat generative power and temperature conductivity coefficients of thermofermentable substances and of the heat flow therein. The rest of the components in the heat balance equation of hotbed are also discussed. Suggestions are then made as to the structure of the hotbeds as well as the management for the postia stratiotes shoot protection.
