滦河下游滨海平原共有土地约240万亩,已开垦利用107万亩,其中耕地面积为68万亩,养鱼10万亩,苇田12万亩,每年生产粮食约4.3亿斤。芦苇3,000万斤,水产品1,500余万斤。其中:柏各庄农场垦殖面积最大为61万亩。 (耕地面积达到36万亩)农场建场以来已生产粮食28亿斤,获利润3,188万元,1980年生产粮食2.6亿斤,芦苇2,200万斤,水产品120余万斤和肉类、果品等多种农产品,盈利2,738万元。滨海盐碱荒地,垦植种稻、经济效益显著。据勘查,滨海地区尚有荒地83万亩,其中宜农地约61万亩,宜养渔植苇地11.5万亩,河口沙地6万亩,滩涂4.5万亩。如能垦种,每年可生产粮食2—3亿斤,以及林,牧,副,渔等多种产品。为此,如何总结该地区土壤改良的经验是一个重要的课题。
Luanhe lower reaches of the Binhai Plain a total of about 240 acres of land, has been reclaimed 1070000 acres, of which 680000 acres of arable land, fish 100000 mus, reed 120000 mus, annual production of about 430000000 jin of grain. Reed 3,000 kilograms, aquatic products 1,500 kilograms. Among them: Baigezhuang farms reclamation area up to 61 million mu. (Farmland area reached 360,000 mu) Since the establishment of the farm, 2.8 billion kilograms of grain have been produced and a profit of 31.88 million yuan has been produced. In 1980, the province produced 260 million jin of grain, 22 million jin of reeds, over 120 kilograms of aquatic products and meat, fruits, etc. A variety of agricultural products, profit 27,380,000 yuan. Coastal saline wasteland, cultivation of rice, significant economic benefits. According to the survey, there are 83 million mu of wasteland in the coastal area, of which 61 million mu are suitable for farming. There are 115,000 mu of land for planting reeds, 60,000 mu of estuarine sand and 45,000 mu of beach. If cultivated species, annual production of 2-3 million kg of grain, and forest, animal husbandry, deputy, fishing and other products. Therefore, how to summarize the experience of soil improvement in this area is an important topic.
