Abstract
This research is conducted by the methods of wiping off 20 cm soil of tilth.It explored the effects of potassium nutrition stress on photosynthesis characteristics and materials accumulation of Bt cotton 33B.The results are as following:potassium stress can significantly inhibit leaf area index (LAI),the effective Pn of the functional leaves of main stem,the accumulation of chlorophyll in the funtional leaves during the mid-and late-stage,and the dry materials of whole plant.With the development of cotton,the inhibition of potassium stress becomes more obvious.With the greatest fitting goodness as the standard,the trend equitions from fitting the curve to data points by EXCEL indicate that potassium stress hardly changes the dynamics of leaf area index(LAI),the effective Pn of the functional leaves of main stem and the dry materials of whole plant,however,to some extent,change the dynamics of the accumulation of chlorophyll in the funtional leaves.
