Abstract通过田间试验,研究了淹灌量和施氮量对黄河三角洲地区棉花生殖分配的影响。结果表明:淹灌量和施氮量对棉花生殖分配有极显著影响,二者有着极显著交互影响。淹灌水深5 cm比水深10 cm有着低的生殖分配,这与其高的枝生物量比有关。适宜的施氮量能够增加生殖分配。相关分析表明,生殖分配与其他器官分配呈显著或极显著负相关。随水肥条件的改善,生殖分配与植株生物量之间由负相关变为正相关。
Other AbstractA field experiment was carried out to study the effects of furrow irrigation quantity and nitrogen application level at sowing date on reproductive allocation of cotton in the Yellow River delta area. The results showed that the furrow irrigation quantity and nitrogen application level exhibited highly significant effects on cotton reproductive allocation,and the interaction between them was very significant. The lower reproductive allocation was showed at 5 cm than that at 10 cm of furrow irrigation depth because of its higher branch mass ratio. Proper nitrogen application level could increase the reproductive allocation. The correlation analysis showed that the reproductive allocation was significantly or very significantly negatively correlated with other organ allocations. As the conditions of water and nitrogen improved,the relationship between reproductive allocation and individual biomass changed from negative to positive
