摘要: 为了揭示安徽省玉米种植密度现状,提出适合安徽不同种植习惯的密度调控对策,为安徽省玉米单产的提高提供科学依据。笔者连续2 年对安徽省玉米产区7 市24 县区进行密度取样调查,分析其株距、行距等密度构成因子。结果表明:安徽省玉米种植平均行距0.55 m,平均株距0.32 m,平均种植密度66870 株/hm2,总体合理,但区域分布不均,主要分为6 个种植习惯区,针对这6 个种植习惯区提出了适度增密,推广耐密品种,调整种植行距,推广玉米播种机械等4条对策。

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.
