Abstract

Abstract:

【Objective】The aim of this study was to evaluate the effects of mixed planting of maize varieties on grain filling characteristics and yield under close planting conditions. 【Method】Zhengdan 958 (ZD958) and Denghai 605 (DH605) were used as experimental materials. Three planting densities (D1, 67 500 plants/hm²; D2, 82 500 plants/hm²; D3, 97 500 plants/hm²), and two different mixed-cropping planting patterns (mixture (M), random sowing after mixing seeds of the two varieties in the same proportion; I, one row of ZD958 and one row of DH605) were arranged, with the same density of Zhengdan 958 (SZD958) and Denghai 605 (SDH605) as controls. Effects of mixed planting of maize varieties on the dry matter accumulation and translocation, grain filling characteristics and yield of summer maize were investigated under close planting conditions. 【Result】With the increase of planting density, the dry matter accumulation of different planting methods after anthesis increased, while the dry matter accumulation per plant at maturity and the grain filling parameters decreased. Although the 1000-grain weight decreased, the population yield increased significantly. There were no significant differences in the grain yields among the different treatments at D1 density. The grain yields obtained under the M and I treatments were higher than those of the monoculture treatments at D2 and D3 densities. Under D2 density, the 2-year average data showed that the grain yields obtained under the M and I treatments increased by 8.70% and 8.09% than that of SZD958, and 6.92% and 6.32% than that of SDH605, respectively. At D3 density, the grain yields obtained under the M and I treatments increased by 7.24% and 7.55% than that of SZD958, and 4.98% and 5.28% than that of SDH605, respectively. At D2 and D3 densities, the G_max(maximum grain-filling rate), W_max(kernel weight at the maximum grain filling rate) and grain weight were increased under the M and I treatments. And the 100-kernel weight was extremely significantly positively correlated with the days needed for reaching the maximum grain-filling rate (T_max), W_max, G_max, and active grain filling period (P) at P<0.01. At D2 density, the average W_max for two years under M and I treatments increased significantly by 11.61% and 11.12% than that of SZD958, and 5.86% and 5.38% than that of SDH605, respectively. The average W_max at M and I treatments at D3 density increased significantly by 10.32% and 9.75% than that of SZD958, and 5.63% and 5.08% than that of SDH605, respectively. The dry matter accumulation per plant at maturity, dry matter accumulation after anthesis, the transfer amount and translocation efficiency of dry matter for M and I treatments increased than those of SZD958 and SDH605. The 2-year average data showed that dry matter accumulation after anthesis obtained under the M and 1:1 treatments increased by 4.43% and 7.56% than that of SZD958, and 5.25% and 8.36% than that of SDH605 at D2 density, respectively. The dry matter accumulation after anthesis obtained under the M and I treatments increased by 3.85% and 4.68% than that of SZD958, and by 4.52% and 5.36% than that of SDH605 at D3 density, respectively. 【Conclusion】There were no significant differences in the grain yields among the different treatments at low density. Under 82 500 plant/hm² and 97 500 plant/hm² density, the mixed cropping significantly increased dry matter accumulation and transport after anthesis, improved the maximum grain filling rate of summer maize and weight of maximum grain filling rate, promoted grain filling, and finally increased the yield significantly.
