摘要
为研究不同栽培方式对玉米产量和经济效益的影响,设置等行距平作、等行距垄作、宽窄行平作和大垄双行4种栽培方式处理,研究不同群体冠层结构对玉米光合性能的调控机制和对玉米产量和经济效应的作用。结果表明:不同栽培方式处理间存在明显差异,其中大垄双行处理的玉米净光合速率、气孔导度、蒸腾速率和产量最高,达到11875.22 kg/hm^(2),经济效益最好,净利润为8258.02元/hm^(2);其次是宽窄行平作处理,产量达到10948.15 kg/hm^(2),净利润为6501.60元/hm^(2)。因此,在河南新郑地区种植玉米可选择大垄双行或宽窄行的栽培方式以达到最佳效益。
To study the effect of different cultivation methods on maize yield and economic benefits,four cultivation methods were set up,including equal row spacing flat planting(treatment 1),equal row spacing ridge planting(treatment 2),wide-narrow row flat planting(treatment 3)and large-ridge double row planting(treatment 4).The study aimed to investigate the regulation mechanism of canopy structure of different groups on photosynthetic performance of maize and the analysis of maize yield and economic effects.The results showed that there were significant differences among different cultivation methods.The maize grown using the large-ridge double-row method had the highest net photosynthesis rate,stomatal conductance,transpiration rate,and yield,reaching 11875.22 kg/hm^(2),with the best economic benefits and a net profit of 8258.02 yuan/hm^(2).The second-best was the wide-narrow row flat-cultivation method,which achieved a yield of 10948.15 kg/hm^(2)and a net profit of 6501.60 yuan/hm^(2).Therefore,for growing corn in Xinzheng,Henan,the large-ridge double-row or wide-narrow row cultivation methods can be chosen to achieve optimal efficiency.
