临沂市位于鲁东南沂蒙山前平原,全市140万亩耕地,60%以上是低洼易涝田。常年种植水稻30万亩左右。但近年来,随着稻麦两熟面积的扩大,加之春末夏初连年干旱.水源日感不足,水稻面积和产量受到很大影响。为了摸索在缺水条件下发展水稻生产的路子,我市自1979年以来,进行了水稻省水栽培试验研究。1983年在太早之年进行较大面积示范,获得成功。 Linyi City is located in the southeastern plains of Yimeng in southeastern Shandong, with 1.4 million mu of arable land in the city and over 60% of them being low-lying and easy-to-flood fields. Perennial planting 300000 acres of rice. However, in recent years, with the expansion of rice-wheat double cropping area, coupled with successive years of spring, late summer and early summer, inadequate water supply, rice area and output are greatly affected. In order to explore the way to develop rice production under water shortage conditions, the city has carried out a pilot study on water-saving cultivation of rice since 1979. In 1983, a large-area demonstration was carried out in an early year and achieved success.
