摘要
根据７～９月田间测定，与空旷地相比，农田林网区平均降低风速２０％、增加相对湿度２％．１２时的温度降低２℃、蒸发量减少１０％；北南林带平均增加粮食产量５％，差异显著，东西林带略有增加，差异不显著。
Measurement from July to September in the field demonstrated that in the rice belt with farmland shelterblet, wind speed and evaporation decrease by 20% and 10%, relative humidity increase by 2%, temperature decrease 2℃ at noon compared with that without shelterbelt. Increase of grain yield by 5% with south-north shelterbelt showed an evident difference compared with the control, but a little with west-east one.
