摘　　要：为提高鲜食玉米种植效益,筛选了最适合"一年两茬"种植的品种,研究了其最适种植密度和播期。结果表明:迪甜10号、迪甜6号、迪糯278、京科糯2000、金菲这5个品种中,迪甜6号最符合"一年两茬"种植模式对品种的要求。优化组合为第一茬4月5日播种,密度为60000株/hm^2;第二茬6月23日播种,密度为46500株/hm^2。净收益为11250-12450元/hm^2。建议在适宜地区广泛推广。To improve the efficiency of the fresh corn planting, screened variety which was most suitable for two cropping one year, and studied the optimum planting density and sowing date. The results showed that： In Ditianl0, Ditian6, Dinuo278, Jingkenuo2000 and Jinfei five varieties, Ditian6 was most conforms to varieties requirements of ＂two cropping one year＂ planting patterns. Optimum combi- nation was the first crop sowing on April 5, 60000 plants/hm2 ; and the second crop sowing on June 23, 46500 plants/hm2. Net in- come was 11250 -12450 yuan/hm2. Ditian6 of ＂two cropping one year＂ planting pattern can be widely applied in appropriate areas.
