| Abstract: | After transgenic cotton residues incubated in soil 430 d,the contents and structural characteristics of soil humus fractions,fulvic acid,humic acid and humin were measured by potassium dichromate titrimetric method and Fourier transform infrared spectroscopy.The results showed that all soil humus fractions increased after the degradation of cotton residues,and the most relative increase was with humin and the least was with fulvic acid.Compared to their near-isogenic non-transgenic cottons,soil humus conten... |
