| 摘 要： | 高产棉田净光合效率日变化和１个明显的峰值，出现在１４：００，它与光合光量子通量密度呈线性正相关。盛蕾期１４：００后的净光合速率较１４：００前小，高峰值多大于花铃期，而花铃期１４：００前后净光合速率无明显差异。分析表明，水分和光照仍是高产棉田光合作用的主要限制因子。

| Abstract: | Diurnal change of net photo synthesis rate(NPR)in Xinjiang cotton fields with high yield had one peak value appearing at 14:00.NPR was positive correlation with photosyn-thetic photon flux density.At the prosperous bud stage,NPR before 14:00 in a day was more than that after 14:00,but at flower or boll stage,NPR before and after 14:00 had little difference.The analysis showed that water and illumination are two of the main limited factors affecting on photosynthesis in cotton fields with high yield.It is better to arrange photosynthate accumulating peak especially the accum ulation of dry matter in buds and bolls in rich light season. Meanwhile,the supply of water and fertilizer should be strengthened. |
