摘要
为在宿州地区筛选出有利小麦收获后复播大豆高产的周年施肥组合,本研究采用裂区试验设计,设置5个小麦季施肥处理、3个大豆季施肥处理,研究周年不同施肥组合对麦后复播大豆农艺性状及产量的影响。研究表明:麦季不同施肥处理的夏大豆株高和产量差异显著。常量处理与常量+生物炭处理的株高显著高于无肥处理,有机肥替代处理的大豆产量比无肥处理高13.20%且差异极显著,高量处理的大豆产量比无肥处理高10.52%且差异显著。大豆季不同施肥处理的夏大豆株高、主茎节数差异显著,且随着大豆季氮肥的增加而增加。大豆季施用氮肥对产量的影响不显著,产量随着氮肥增加先升高再降低。麦季施用有机肥,大豆季施用低氮基肥的周年施肥组合有利于在获得较高大豆产量的同时减少对环境的负面影响和氮肥用量。
In order to screen out better annual fertilization combination for the high-yield of summer sowing soybean,this experiment adopted the split area experiment design,and set up five fertilization treatments in wheat season and three fertilization treatments in soybean season.The effects of different annual fertilization combinations on agronomic traits and yield of soybean were studied.The results showed the different fertilization in wheat season had a significant aftereffect on the plant height and yield of the summer soybean.Plant height in the customary fertilizer and customary fertilizer+biochar treatments were significantly higher than that of no fertilizer treatment.The yield of organic fertilizer treatment was 13.20%extremely higher than no fertilizer treatment.The yield of high amount treatment was 10.52%higher than no fertilizer treatment.The plant height and main stem node number of summer soybean were significantly affected by different fertilization in soybean season.Soybean plant height and main stem node number increased with the increase of nitrogen fertilizer in soybean season.Nitrogen fertilizer had no significant effect on yield in soybean season.The yield of soybean rised and then fell with the increasing of nitrogen fertilizer.It was beneficial to soybean yield enhancement under organic fertilizer in wheat season and low nitrogen-based fertilizer in soybean season.
