In addition, aerodynamic roughness of stubble field increased with the increasing of stubble height, until the heights reached 15, 30, 15 cm for naked oats stubble, oilseed rape stubble and wheat stubble, respectively.

同类作物不同高度的留茬覆盖下，地表空气动力学粗糙度随留茬高度的增加而增大，在莜麦、油菜和小麦茬高度达到15、30和15 cm时显著增大，是3种留茬防风的有效高度。

The experiment use cucumber as materials, There were two stubble cultivation includingspring stubble and autumn stubble. Three temperature environmentwere setted upby opening back slope ,back wall and front ventilation mouth or cover of many layers ortemporary hightened temperature. Jinchun 3 was used in spring stubble and Jinyou 1 was used inautumn stubble. The experiment initially ascertained that different temperature conditions ingreenhouse influence on growth and yield of cucumber by studying different temperaturetreatments effect on atmosphere factors (air temperature, ground temperature and relativehumidity), growth, correlated physio-biochemical index and yield of cucumber, which couldprovide reasonable temperature parameters for greenhouse cucumber cultivation in our province.

本试验以黄瓜（Cucumis sativus.L）为材料，分为温室春秋两茬栽培，通过开启后坡、后墙、前侧通风口大小、多层覆盖、临时加温等手段，设置 A、B、C 三个温度环境，春茬选用品种为津春 3 号，秋茬为津优 1 号，通过研究不同温度管理方式对日光温室内气象因子(气温、地温和空气相对湿度)及黄瓜的生长、产量、相关理化指标、果实商品性、品质的影响，初步探明日光温室内不同温度管理对黄瓜生长及产量形成的影响，为我省日光温室黄瓜栽培环境控制提供合理的温度参数。
