摘要
本文通过不同光照强度和不同ＣＯ２浓度对马蹄金光合速率影响的测定，结果表明：马蹄金光补偿点和光饱和点分别为３ｋｌｘ和８０ｋｌｘ；ＣＯ２补偿点和光合速率（在２８℃，ＣＯ２浓度为３３０ｐｐｍ，光强为６０ｋｌｘ条件下）分别为７０ｐｐｍ和３２。７８ｍｇＣＯ２／ｄｍ２·ｈ．并对生殖期。
In this papet,by the determination of different light intensity and different CO2 concetration to its effect of the photosynthetic rate、The photosynthetic Characteris tics of Dichondra repens L.,a kind of ornamental Lawn Plant.are showed that light compensation point is 3 klx,light saturation point 80 klx,CO2 compensation point 70ppm and photosynthetic rate 32.78mg CO2/dm2.h under the condition of 28℃,CO2 con centration 330 ppm and light intensity 60 klx. Meanwhile,the biological characteristic of its reproductive,period seed genmination and sexual reproduction are observed.
