为揭示氮肥对超高产大豆花、荚形成及产量的影响规律.田间研究了施纯氮(0,45,90,135 kg/hm2)处理对中黄35叶片生长、开花、结荚及产量的影响.结果表明,施氮90,135 kg/hm2较未施氮明显增加主茎第9节至第15节的叶面积和群体叶面积指数,增加第9节至第14节花数、第6节至第16节荚数和腔数,开花期、结荚期分别延长0~4 d,0~12 d；单位面积总花数、腔数和产量分别增加8．4％~37．4％,3．9％~29．2％,3．1％~11．5％,施氮135 kg/hm2处理的产量达6514．8 kg/hm2,其总花数为3489．5×104朵/hm2,总腔数为3349．5×104个/hm2.开花期施氮肥增产的重要原因是促进上部节叶片生长,增加群体叶面积指数,并延长开花期和结荚期,增加上部节的花数、荚数和腔数.超高产大豆田的适宜施氮量为90 kg/hm2左右.
為揭示氮肥對超高產大豆花、莢形成及產量的影響規律.田間研究瞭施純氮(0,45,90,135 kg/hm2)處理對中黃35葉片生長、開花、結莢及產量的影響.結果錶明,施氮90,135 kg/hm2較未施氮明顯增加主莖第9節至第15節的葉麵積和群體葉麵積指數,增加第9節至第14節花數、第6節至第16節莢數和腔數,開花期、結莢期分彆延長0~4 d,0~12 d；單位麵積總花數、腔數和產量分彆增加8．4％~37．4％,3．9％~29．2％,3．1％~11．5％,施氮135 kg/hm2處理的產量達6514．8 kg/hm2,其總花數為3489．5×104朵/hm2,總腔數為3349．5×104箇/hm2.開花期施氮肥增產的重要原因是促進上部節葉片生長,增加群體葉麵積指數,併延長開花期和結莢期,增加上部節的花數、莢數和腔數.超高產大豆田的適宜施氮量為90 kg/hm2左右.

The precent study was carried out to discuss the effect of N fertilizer on the formation of flow-ers,pods and output of Zhonghuang 35 super-high yield soybean.The results showed that N fertilizer appli-cation (90,135 kg/hm2 )may increase the indexes of leaf area and population area,flower number between 9th and 15th internod,pod number,flower number between 9th and 14th internod,pod number and cavity number between 6th and 1 6th internod of main stem;the flower stage and bearing pod stage prolonged 0-4 d,0 -12 d;The total flower number,cavity number and yield of unit area increased by 8.4%-37.4%, 3.9%-29.2%,3.1%-1 1.5% respectively.If N fertilizer of 135 kg/hm2 were applied,the yield would reach 65 14.8 kg/hm2 ,whose total flower number was 3489.5 × 10 4 per hectare,total cavity number was 3349.5×10 4 per hectare.N fertilizer application at the flower stage can improve leaf growth on upper inter-node of soybean plant,thereby can increase production of Zhonghuang 35,increase indexes of population ar-ea,also can prolong flower stage and bearing pods stage and flower number,pod number and cavity number on upper internode.
