AbstractThis paperanalyzed thebasic conditions for rice cultivation in the Rudongarea of Nantong City,Jiangsu Province,andsystematicallysummarized thekey technologies forlocal ricecultivation.Theregionisrich inlightand heatresourcesandhas thepotentialforincreasing rice production,buttyphoons,hightemperaturesandsoilsalinization havecertain impacts on rice production.Basedon this,the paper integrated core technologies such as variety breeding, precise waterand fertilizer management,and green preventionand control,andestablished riceplanting technologies suitable forregional ecological conditions.Specifically，it includesscreening salt-tolerant genotypes with stable resistance varieties,such as Nanjing 5055,etc.; adopting dry seedling raising technology，constructinga dry seedling bed with coordinated regulation of physical structure and chemical environment,and conducting stress adaptation training whenthesecondandahalfleaf of theseedling unfoldsand5daysbeforetransplanting tocultivateresistantand vigorous seedlings; constructing a precise controlled-release system of compound fertilizer nutrients in time and space (the peak periodofnitrogen releaseis in linewith thetillring peak period,andthephosphorusactivityis maintained untiltheyoung paniclediferentiationperiod)，with theapplicationratesofnitrogen，phosphorusandpotassium fertilizers being 165,75 and 105kg/hm2 respectively; establishing a dual-track water regulation mechanism of “salt drainage and alkali suppresson-physiological water demand”,and implementing precise water regulationof“shallow water promoting tilering-inch water protecting the embryo-dry and wet preventing senescence";constructingagreen controlsystem,through the coordinated effctof physical (setting upsoundand light combination traps,etc.）and biological (spraying 2OO billion spores/g Bacilus subtilis wettablepowder,etc.）control，maintaining theratioof beneficial to harmful organisms in the paddy field ecosystem at 1:2 . This paper provides a reference for green, stable and high yield rice production in coastal saline-alkali areas
