摘要
通过实地调查,分析了沟渠河路农田林网的综合效益,认为沟渠河路农田林网具有降低风速、调节温度、稳定湿度的小气候效应,有减轻风害、冻害,防御灾害性天气的效应,还有调节农作物生长发育期,增加粮、棉、油菜产量的效应。
Through on-the-spot investigation,this paper analyzed the comprehensive benefits of farmland and forest shelter networks for ditches, canals, rivers and roads, and thought that the nets had such the effects of microclimate as breaking down speed of wind, regulating temperature and moisture, and it could also reduce the wind damage and freeze injury and defend the disaster weather,moreover, it could regulate the growth-period of crop and improve the output of grain, cotton, oil crops.
