- 摘要:
- 为探讨肥料对大豆产量和品质的影响规律,在大田条件下,以大豆品种合丰55为供试材料,设不施肥、常规尿素、控释尿素3个处理,对大豆株高、叶绿素含量、干物质积累及产量和品质进行了研究。结果表明:与施用普通尿素相比,控释尿素提高了大豆的株高、叶绿素含量值以及干物质积累;提高了大豆的蛋白质含量,降低脂肪含量,改善大豆品质。控释尿素提高大豆产量,与不施肥相比产量提高21.19%,方差分析差异达极显著水平;与普通尿素相比产量提高5.77%,差异达显著水平。
- Abstract:
- To investigate the influence law of fertilizer on soybean yield and quality,Hefeng55 was used as material,the effect of three treatments of no fertilizer,common urea and controlled release urea on soybean plant height,chlorophyll content,dry matter accumulation and yield and quality were studied under field condition.The results indicated that compared with common urea,CRU promoted plant height,chlorophyll content and dry matter accumulation of soybean,the protein increased and fat decreased and improved soybean quality.CRU promoted yield of soybean,increased yield by 21.19% compared with no fertilizer treatment,the difference reached very significant level,increased yield by 5.77% compared with common urea application,the difference reached significant level.
