农田防护林设计与营造工作,在我省已有二十多年的历史。从1952年开始,根据国家统一规划,进行了调查设计,北起甘南、富裕两县,西接内蒙,南与吉林的扶余、大安两县隔江相望,在这辽阔的松嫩平原上,设计与营造起总长86000公里,123万亩农田防护林,构成34000个农田网格、庇护着两千多万亩农田。在一定程度上减少了风砂、干旱,为农作物的生长,发育创造了条件。但是,由于十年动乱,致使我省农田防护林建设速度迟缓,质量不高,零星分散,受益面积小,没有从根本上改变我省自然面貌和农业生产条件,特别是黑龙江省纳入“三北”防护林体系
Farmland shelterbelts design and construction work in our province has more than 20 years of history. Since 1952, according to the unified planning of the state, the survey and design has been carried out. From south to south, there are two counties of Gannan and Fuyu. In the west, Fuyu and Da’an counties of Inner Mongolia and Jilin and Daan counties across the river. On this vast Songnen Plain, To create a total length of 86,000 kilometers, 123 acres of farmland shelterbelts, forming 34,000 farmland grid, sheltered more than 20 million mu of farmland. To a certain extent, reduce the wind sand, drought, for crop growth and development to create the conditions. However, as a result of the ten year turmoil, the construction of farmland shelterbelt in our province was sluggish, of low quality, sporadic scattered and of small benefit. It did not fundamentally change the natural appearance of our province and the conditions of agricultural production. In particular, Heilongjiang Province included the “Three Norths” Shelterbelt system
