Research on Sowing and Fertilization of a New Maize Variety‘Jikeyu 12'

在玉米新品种一吉科玉12的适应区域内进行了配套栽培技术研究，．结果表明，吉科玉12的适宜播种期为5月1—4日、播种方法为手提式播种机、播种量每穴1—2粒、播种深度3．0～4．0cm；种植密度为5．0万～5．5万株／hm。；最佳施肥量为：公顷纯N、P、K分别为（186．2±15）kg、（84．2±5）kg、（92．5±10）kg。

The corresponding cultivation techniques of a new maize variety ＇Jikeyu 12＇were researched in the area of adaptation. The results showed that the suitable sowing time of ＇Jikeyu 12＇was May 1 to 4, the seeding method was to use portable drill, the seeding rate was 1 to 2 per hole, the sowing depth was 3.0 - 4.0cm, the planting density was 50 000 -55 000 plants per hectare. The optimum fertilization was of N, （186.2 ±15） kg, P, （84.2 ±5） kg and K, （92.5 ± 10） kg per hectare
