我省有漫长的海岸线,沿海的贝壳、海草、海泥等资源十分丰富。利用这些资源可以制成多种海肥,有利于培肥地力,提高农作物产量。据金县大孤山公社试验,每亩耕地施贝壳粉、小海蛎子等海肥600～1,000斤,玉米、小麦、大豆的增产幅度分别为4.8～9.7％、11.1～25.6％、15.2～21.5％。近三年来,大孤山公社每年施海肥1,400万斤,使1.4万亩耕地增产粮油100万斤,增收8万元,肥料开支节省9.4万元。目前,金县已将海肥作为重要肥源,每年施用海肥5,500～7,200万斤。
My province has a long coastline, coastal shells, seaweed, sea mud and other resources are very rich. Use of these resources can be made of a variety of sea manure, fertilizing fertility is conducive to improving crop yields. According to the Dagushan commune test in Jinxian County, 600-1,000 kg of sea manure, such as Shi shell powder and Oyster oyster per acre of arable land, were 4.8-9.7%, 11.1-25.6% and 15.2-21.5 respectively for corn, wheat and soybean %. In the past three years, the Dagushan commune has applied 14 million kilos of sea-manure every year, boosting 1.4 million mu of cultivated land to produce 100 million jin of grain and oil, increasing the income by 80,000 yuan and saving the fertilizer expenses by 94,000 yuan. Currently, Jinxian has made sea manure an important source of fertilizers, applying 5,500 to 72 million kilograms of sea manure each year.
