Abstract
For the purpose of defining reasonable density,the effect of different density on the soybean physiological characteristics with Changnong 18 as test materials was studied.The results showed that chlorophyll content changes were all increasing at first and then decreasing,photosynthetic rate present diauxie curve changes,appeared twice photosynthetic peak values.Transpiration rate and stomatal conductance value from the maximum of V4 period gradually reduced to the minimum of R7.The accumulation of dry matter yield presented a S shape curve change,and at R7 reached maximum.The effect of planting density on the chlorophyll content was as follows:from V4 to R7 period showed obvious difference,chlorophyll content of low density was higher than that of high density,in a certain density range,with the increase of planting density,photosynthetic rate reduced,the intercellular CO2 concentration increased,group leaf area index increased,the accumulation of dry matter yield decreased.The transpiration rate and stomatal conductance change trend were the same,with the reduction of planting density,transpiration rate rised and stomatal conductance got big.
