In this study, Xiangzamian F7 was as experimental material and four experimental treatments were made.
Which are: Pirformaspore Indica to be as base fertilizer (0P), P. indica P. Indica to be added into soli respectively before and
after cotton seedlings suffering from subsurface waterlogging (+P, P+) and cotton seedlings merely encountering
subsurface waterlogging (CK). This study aimed to study the influence of P. Indica to cotton growth and the main
enzyme activity under the waterlogged stress condition. The results showed that: the leave area and height of 0P, +P
were higher than that of CK and P+ obviously during the waterlogged stress and the recover after waterlogged
stress. The Chlorophyll and sugar content of 0P and +P leaves were higher than P+ and CK leaves after removing
from the waterlogged stress. The MDA content of 0P and +P increased slowly during waterlogged stress and the
recover after waterlogged stress. The SOD activity of 0P and +P seeding went quickly up under 15 days
waterlogged stress. The POD activity of 0P and +P went down during 15-day waterlogged stress, but the POD
activity of CK and P+ increased. The above results showed that P. Indica could improve cotton resistance to
waterlogged stress. In order to improve cotton resistance to waterlogged stress, suggesting P. Indica as base
fertilizer, at the same time, adding P. Indica into soli before cotton seedlings suffering from subsurface
waterlogging, the effect of cotton resistance to waterlogged stress will be better.
Key words: Enzymatic activity, morphological index, Pirformaspore Indica, waterlogged disaster, xiangzamian F7, ,
