Abstract

Abstract: To reveal the present situation of maize planting density in Anhui Province, and put forward control measures to improve maize yield per unit area in Anhui, investigations on maize planting density were carried out for 2 consecutive years in 24 counties of 7 cities in Anhui Province, and the density components such as row spacing and line spacing were analyzed. The results showed that the average line spacing and the average row spacing of maize in Anhui was 0.55 m and 0.32 m, respectively, and the average planting density was 66870 lants/hm2. The planting density was overall reasonable, but the regional distribution was uneven, which was mainly divided into 6 planting habits areas. Four countermeasures including moderate densification, promotion of new varieties, planting spacing adjustment and popularization of maize sowing machinery were put forward in view of these 6 planting habits areas.
