Abstract: 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 72 000 plants/hm2.
