以普通小麦品种为材料,对不同供氮水平下植株碳、氮物质积累分配特征及与籽粒蛋白质的关系进行了探讨。结果表明,籽粒积累的氮素主要来自前期营养器官贮存氮素的再分配,但不同品种存在着差异。低蛋白品种京花1号对前期营养器官贮存氮素再分配的依赖性更强,中蛋白品种冀麦23次之,高蛋白品种京771除依赖于前者外,还依赖于生育后期植株对氮素的继续同化和吸收。在籽粒生长发育过程中,籽粒氮素含量的变化曲线呈凹形,全糖含量呈凸形,籽粒氮的积累曲线呈“S”形。与低蛋白品种相比,高蛋白品种籽粒碳氮化合物的积累较为平衡。各品种籽粒产量和蛋白质含量都受供氮水平的影响,在一定的供氮范围内增施氮肥,籽粒产量和蛋白质含量可同步增加

This research was conducted in low yield fields(lint about 750 kg/hm 2),middleyieldfields(lintabout1125kg/hm 2),highyieldfields(lintabout 1 500 kg/hm 2) and super high yield fields(lint about 1 875 kg/hm 2) in Changsha,Changde and Nanxian of Hunan from 1992 to 1998. The results obtained showed that N contents in cotton plants of various yield fields varied a lot. With the rise of yield and application of N fertilizer, N contents in cotton plants increased.

The results obtained showed that N contents in cotton plants of various yield fields varied a lot. With the rise of yield and application of N fertilizer, N contents in cotton plants increased. Whats more,N contents in different organs differed significantly. The ratio of N contents between vegetative organs and reproductive organs was 4∶6. Of the N contents in vegetative organs,most parts were stored in leaves,occupying about 30% of the whole N contents in plants. Cotton seed,a economic produce,and cotton pur,a reproductive organ,contained more N than other organs,ie about 40% and 15% of the whole N in plant respectively.

为探讨不同产量类型棉田棉株含氮量的变化特点 ,1 992~ 1 998年 ,对湖南农业大学、常德和南县等地的低产 (产皮棉约 750 kg/ hm2 )、中产 (产皮棉约 1 1 2 5kg/ hm2 )、高产 (产皮棉约1 50 0 kg/ hm2 )和超高产 (产皮棉约 1 875 kg/ hm2 ) 4种产量类型棉田棉株各器官的含氮量进行了研究 .结果表明 ,不同产量类型棉田棉株中贮存的氮差异很大 ,表现为随棉田产量水平的提高和施氮量的增多而增加 .棉株不同器官 (部分 )贮存的氮也明显不同 ,营养器官贮存氮与生殖器官贮存氮之比约为 4∶ 6.在营养器官中绝大部分氮贮存在叶片中 ,约占植株总氮量的 30 % .生殖器官中棉子作为经济产品输出棉田 ,带走了棉田生态系统中棉株库总氮量的 40 % .棉铃壳虽为生殖器官 ,而非经济产品 ,其含氮量较多 ,约占棉株库总氮量的 1 5% .

A field experiments was carried out to investigate the effects of nitrogen topdressing time on the (nitrogen) accumulation and transfer, grain yield and protein content of two specialty wheat cultivars, Xumai 26 and Huaimai 18 under high yield conditions. The results showed that the nitrogen topdressing at jointing and (booting) stages increased the grain yield and protein content but the topdressing at heading and flowering stages might be unfavorable to simultaneously increase the yield and protein content....

A field experiments was carried out to investigate the effects of nitrogen topdressing time on the (nitrogen) accumulation and transfer, grain yield and protein content of two specialty wheat cultivars, Xumai 26 and Huaimai 18 under high yield conditions. The results showed that the nitrogen topdressing at jointing and (booting) stages increased the grain yield and protein content but the topdressing at heading and flowering stages might be unfavorable to simultaneously increase the yield and protein content. Compared with the (no-topdressing) treatment, the topdressing treatments significantly increased (post-anthesis) (nitrogen) (assimilation) of Xumai 26, decreased the transfer of reserved nitrogen in vegetative organs to the grain but increased that in Huaimai 18. The correlation analysis showed that grain protein content of Xumai 26 was significantly correlated with the post-anthesis nitrogen assimilation, However the grain protein content of Huaimai 18 was significantly correlated with the transfer of reserved (nitrogen) in vegetative organs. The results indicated that different (nitrogen) topdressing time should be adopted in promoting the grain protein content for different specialty wheat (cultivars).

为了明确施氮时期对小麦花后干物质和氮素积累与运转的影响及其与产量和品质的关系,在大田高产条件下,研究了不同追氮时期对二个专用小麦品种开花前后氮素同化、运转和蛋白质含量的影响。结果表明,拔节和孕穗期追氮均提高了小麦产量和籽粒蛋白质含量,但过迟追氮不利于产量和蛋白质含量的同步提高。不同追氮处理显著提高了徐麦26花后氮素积累量,降低了营养器官贮存氮素向籽粒的转运,但提高了淮麦18营养器官贮存氮素向籽粒的转运。相关分析表明,徐麦26籽粒蛋白质合成所需氮素主要来源于花后氮素同化,而淮麦18则更多地依赖于开花前贮存氮素的再动员与分配。
