台安县地处渤海湾附近,是低洼易涝地区,境内有五条河流贯穿南北,仅辽、浑两河全长达二百一十多华里,宜林面积可达四万余亩。为了护堤、固坡、防浪和保田增产,全县人民在毛主席“绿化祖国”的号召鼓舞下,从一九六五年开始绿化大堤,到一九七四年全境百分之七十左右堤坝堤坡两侧栽上了紫穗槐,百分之五十左右堤坝迎背水面堤坑栽上了杨柳树,现已成材受益,并起到了保护农田的作用。栽值方法是:堤坡两侧由堤顶一米以下处栽十五至二十行紫穗槐,行距一米,穴距半米,按坡度呈三角形配置。两侧堤坑迎水面栽植耐水能力强生长旺盛的旱柳,为防止水流冲堤角,栽植方法是雁翅形,株行距为一米。背水面坝坑栽植生长快、材质好的杨树,株行距各一米。
Taian County is located in the vicinity of Bohai Bay. It is a low-lying flood prone area. There are five rivers throughout the country. Only Liaoning and Hunliang have a total length of over 210 li and the area of Yilin reaches 40,000 mu. Inspired by Chairman Mao’s call for “greening the motherland,” the people of the entire county, in order to protect the berm, solid slope, waves and increase the yield of the Baotian, started to green the embankment from 1965 to 7% of the territory in 1974 Around ten embankment embankments planted with Amorpha fruticosa, about 50% embankment embankment embankment planted willow trees, has now become a timber to benefit, and played a role in protecting farmland. Planting method is: embankment slopes on both sides of the embankment at a meter below the plant fifteen to twenty rows of Amorpha fruticosa, row spacing of one meter, half a meter from the hole, according to the gradient was triangular configuration. Water embankment on both sides of the embankment planted with strong water-resistant ability to grow vigorous growth of Willow, in order to prevent the runoff angle of water flowering, planting method is wild-eared shape, spacing of one meter. Backwater dam planting rapid growth, good material poplar, plant spacing of one meter.
