摘　　要：吉单198在吉林省湿润冷凉区桦甸市播种面积达到40%以上,为发挥其最高生产潜力,2006—2007年进行试验研究,得出该品种最适播种方法为播种器播种,播深3～4cm,播种量1～2粒/埯,最适种植密度为46000～47000株/hm2,N、P和K施用量分别为194、81和96kg/hm2,在拔节期喷施化控剂国光225ml/hm2。形成吉单198在该地区丰产高效栽培技术体系,为提高该区域玉米高产稳产的生产能力提供技术保障。The cultivated area of corn variety Jidan 198 has reached 40% in cold and humid region in Jilin Province. To exploit the productive potential, cultivated experiments of Jidan198 were carried out during 2006 to 2007. A set of highly efficient cultivated technique system of Jidan 198 was received in this region. This system covered five techniques： The best sowing pattern was using seeding-machine with seeding depth 3～4cm. The optimum seeding quantity was 1～2 seed per hole. The planting density was 46000～47000 per hectare. Rate of fertilizer application was N 194kg/hm2, P2O5 81kg/hm2 and K2O 96kg/hm2 respectively. Plant regulator Guoguang was sprayed with a concentration of 225ml/hm2 in jointing stage. This technique system will ensure highly efficient production ability of corn in cold and humid region in Jilin Province.
