鲁东半岛地区夏玉米播期密度研究

Study on Sowing-date and Planting Density of Summer Maize in Peninsula Area of Shandong Province

为实现半岛地区小麦玉米双高产,探明适宜的配套栽培技术,通过选用玉米品种‘登海605’,采用5个播期和3个密度的试验方法,研究‘登海605’在半岛地区适宜的播期和密度。结果表明:‘登海605’适宜播期是6月15日至6月21日,在适期内争取早播,以实现高产,最佳密度为7.2万株/hm2。

In order to achieve high output both wheat and maize, ascertain the suitable cultivate technology in peninsula area. Using the maize variety of ＇Denghai605＇ and the experiment method of five sowing-date and three planting density, the suitable sowing-date and planting density of ＇Denghai605＇ in peninsula area were studied. The results showed that, the suitable sowing-date of ＇Denghai605＇ was from June 15th to 21st, and the more early, the higher yield, the suitable planting density was 72000 plants/hm2.
