烟幕防御香蕉低温害的效应

The defence effect of smoke screen on low temperature injury to banana

在4种天气型背景下进行熏烟试验,结果表明,烟幕对辐射低温具有明显的保温防寒作用;气温越低,保温效果越好;在香蕉园中最茂密的高度层保温作用较强;阴晴天气、不同湿度对烟幕保温效果没有明显的影响.

Smoke screen experiments under four types of weather conditions were carried out in a banana plantation.The results showed that smoke screen prevented radiative low temperature.The lower the air temperature was,the better the heat preservation effect was got.The heat preservation effect was stronger at the densest height than at other heights in the banana plantation. The heat preservation effect of smoke screen was not significantly affected by sky conditions (sunny or overcast) and air humidity.
