北疆复播地膜玉米的气候适应性初探

Preliminary Study to Climatic Adaptation of the Re-seeded Corn Covered with the Plastic Film in the Northern Xinjiang

北疆乌兰乌苏的地膜玉米分期复播田间试验表明:随着复播日期的推迟,收获籽粒的百粒重和单穗籽粒干重呈下降趋势。7月5日前播种,90d以上的生长期,≥10℃活动积温2000℃·d,才能保证复播地膜玉米承单3号的正常成熟。

According to field experiment of re - seeded corn at Wulanwusu agricultural meteorological station located in the Northern Xinjiang shows that the weight of the seeds of single spikes of corn and 100 seeds reduce with the prolongation of sowing time and corn re- seeded under the plastic film can be ensured normal growth under seeding before Jul. 5, growth period of 90d and≥10℃ active accumulated temperature 2000℃.
