一、试验背景柏各庄农场位于唐山市以南,紧靠渤海北岸。面积104.6万亩,大多为滨海低平原,其中潮上带和潮间带有29.9万亩。地势低平,海水肥沃,含盐量等理化指标适当,为人工养殖对虾提供了得天独厚的条件。 1974年五分场渔林队就开始孵化虾苗和粗养对虾,产量很低。1985年,柏各庄农场在逆境中奋力开拓,历经七个春秋,付出艰苦卓绝的努力,终于确立了养虾业在全国的领先地位。日前全场有虾池66970亩,年产对虾万吨左右,连续四年获得总产,规格、
First, the experimental background Baigezhuang farm is located south of Tangshan City, close to the north shore of the Bohai Sea. An area of 1,046,000 mu, mostly low coastal plain, of which the tide and intertidal zone with 299,000 mu. Low level, fertile sea water, salt and other physical and chemical indicators appropriate for the artificial breeding of shrimp provides a unique condition. In 1974, five-point field forestry team started hatching shrimp and crude shrimp, the yield is very low. In 1985, Baigezhuang Farm worked hard to open up in adversity. After seven years of hard work, it made arduous efforts and finally established its leading position in the country. Recently the audience shrimp pond 66970 mus, with an annual output of 10,000 tons of shrimp, for four consecutive years of total production, specifications,
