在吉林省湿润冷凉区,研究9个玉米中晚熟品种的农艺性状、生育期、抗逆性和产量表现。结果表明:参试品种中吉品67和宏育29产量最高,分别为12 345.0 kg/hm2、12 144.0kg/hm2;每公顷玉米种植密度在6.0万株~6.21万株,以种植吉品67和宏育29为主;每公顷玉米种植密度在5.25万株~5.3万株,以种植平全13为主。为湿润冷凉区玉米高产、优质、高效技术集成提供科学依据。
In the humid and cool area of Jilin Province, the agronomic traits, growth period, stress resistance and yield of 9 middle and late-maturing maize varieties were studied. The results showed that the yield of the two varieties was 12 345.0 kg / hm2 and 12 144.0 kg / hm2, respectively; the density of corn per hectare was 60,000 ~ 62,100, 29; the planting density of corn per hectare is 52,500 to 53,000, and the planting level is 13%. To provide a scientific basis for high yield, high quality and efficient technology integration of wet and cool area corn.
