| 摘 要： | 在田间试验条件下,研究了不同滴灌水量对南疆膜下滴灌杂交棉花"兆丰1号"光合性能及产量结构的影响.结果表明,限量滴灌造成棉田土壤水分亏缺,单叶光合速率(Pn)和群体光合速率(CAP)降低,群体呼吸速率(CR)及CR占群体总光合速率(TCAP)的比值在盛花期较高,进入盛铃期以后CR又显著低于适量滴灌处理,叶面积指数(LAI...

| Abstract: | The effects of water-saving drip irrigation on photosynthetic characteristic and yield components in hybrid cotton Zhaofeng 1 in Southern Xinjiang were studied.The results showed that limited drip irrigation caused water deficiency in cotton field,and reduced the rate of net single-leaf photosynthetic(Pn),canopy apparent photosynthesis(CAP) and leaf area index(LAI);In limited irrigation treatment,the canopy respiration rate(CR) and the ratio of CR to total CAP were higher in full flower stage but the CR was... |
