农田防护林是平原绿化的组成部分。在护堤抗风,加强抗御灾害天气的能力,改善农业生产小气候环境条件,保障垦区农业生产的稳定和高产方面,防护林带(网)的作用愈来愈明显,且可为人民生活和建筑提供用材。最近几年,珠江三角洲农田防护林在迅速发展,防护面积不断扩大。1979年在斗门县白藤湖垦区营建4,000亩试验林网,近年扩展到邻近的白蕉东湖垦区、平沙农场、乾务、莲溪区及新会县小岗、沙堆区和崖南围垦区,农田林网防护面积达十万亩以上。
Farmland shelterbelts are part of the plains greening. The role of shelter belts (networks) has become increasingly evident in the windmills of berms, the ability to resist disastrous weather, the improvement of microclimate conditions in agricultural production, and the stability and high yield of agricultural production in reclamation areas, and can provide people living and building services Material. In recent years, the farmland shelterbelt in the Pearl River Delta has been developing rapidly and the area of protection has been constantly expanding. In 1979, 4,000 mu of experimental forest net was set up in Bai Teng Lake Reclamation Area in Doumen County. In recent years, it has expanded to adjacent Bajiao Donghu Reclamation Area, Pingsha Farm, Gannian County, Lianxi District, Xiaogang County, Shadui District and Yaonan Reclamation Area , Farmland net protection area of one hundred thousand acres or more.
