Effects of Remedial Measures Implemented after Waterlogging on Cotton

In south China, water logging occurs frequently in spring and summer which generally affect crops´ normal growth and final output, so it is important for agricultural production to effectively prevent water logging damage. A test-pit experiment was made in the period of cotton flowering that nutrient regulators were applied to cotton growth recovery aiming at its plants under water logging for 10 days. The results showed that, cotton plants during waterlogged stress, POD activity and MDA content rise with the increase of waterlogged time meanwhile SOD activity decline, the use of plant growth regulators and foliar fertilization can improve physiological metabolism of cotton plants in a certain degree, and obviously decrease in the yield loss. According to the results, a good effect for cotton plants recover from water logging adversity can get as long as proper plant growth regulator was used for roots detoxification and their wound healing while foliar fertilization was added timely for nutrient supplement.
