Abstract

Abstract:

【Objective】 The aim of this study was to explore the regulatory effects of expanding and shrinking cultivation models under different densities on the yield and population structure of Huang-Huai-Hai summer maize. 【Method】 The high yield maize variety Zhengdan958 was used as experimental material, three kinds of row spacing treatments, such as 60 cm (B1), 80 cm (B2), and 100 cm (B3), and two planting densities of 67 500 plants/hm²and 82 500 plants/hm², were used to form different cultivation patterns through split zone design in 2018 and 2019. 【Result】 Compared with D1 density, D2 density could significantly increase the population leaf area and photosynthetic potential, improve the light energy utilization of the population, increase the dry matter accumulation of the population, and promote the increase of yield. Under the condition of different planting density, the effect of expansion and shrinkage on population structure was different. Under the density of 67 500 plants/hm², the effect of expansion and shrinkage on the yield was not significant. Under the density of 82 500 plants/hm², B2 treatment increased the yield by increasing the number of grains per row and 1000-grain weight, which was 9.45% and 11.48% higher than that of B1 and B3 treatments, respectively. B2 treatment significantly increased the population leaf area index (LAI), delayed the senescence of the middle and lower leaves, increased the photosynthetic potential of the population after anthesis, increased the angle between stems and leaves, and decreased the leaf orientation value. The light transmittance of leaf layer and bottom layer in panicle position increased significantly, the extinction coefficient decreased, the dry matter accumulation increased after anthesis, and the dry matter transfer decreased after anthesis. The results showed that under the condition of high density, the equal row spacing model of 80 cm expansion was beneficial to build an efficient photosynthetic population structure, delay leaf senescence, improve the photosynthetic performance of the population, increase the production and accumulation of dry matter of the population, and thus increase the yield. 【Conclusion】 The high-yield cultivation of summer maize in Huang-Huai-Hai Plain can achieve efficient utilization of light energy and synergistic increase in yield by increasing planting density and appropriate expansion and shrinking of plants. Under the experimental conditions, a planting pattern of 82 500 plants/hm² with a density of 80 cm is recommended.
