平原林业,亦可称谓平原农区林业(下同)。它虽然起步较晚,但发展速度很快。建国初期的五十年代,平原林业主要是“四旁植树”的形式,六十年代形成了第一个高潮。进入七十年代,由于农田林网和农林间作(主要是桐粮间作)的发展,平原林业开始由“四旁植树”迅速地转向“平原绿化”。经过八十年代的奋斗与实践,我们开始掌握了平原农区林业发展的规律,并初步把握了它发展的方向、路 Plain forestry can also be referred to as plain farming forestry (the same below). Although it started late, it has developed rapidly. In the fifties of the early years of the founding of the People’s Republic of China, the plain forestry was mainly in the form of “planting trees all around” and the first climax was formed in the 1960s. Into the seventies, due to the development of farmland forest network and intercropping with agriculture and forestry (mainly Tongtong intercropping), plain forestry began to shift rapidly from “planting trees all around” to “plains greening.” After the struggle and practice in the 1980s, we began to grasp the law of the development of forestry in the plain farming areas and initially grasped the direction of its development.
