Study on the Effects of Several Kinds of New Super Absorbent Polymers on Soil Leaching Loss of Water and Nitrogen and Growth of Flowering Chinese Cabbage

This paper studied the effects of three kinds of new super absorbent polymers on soil evaporation, nitrogen and water leaching and growth of flowering Chinese cabbage through simulation experiment and pot experiment. The soil cup leaching experiment showed that the soil water content in treatment with super absorbent polymers increased from 7.10% to 28.42% on average. The soil column test showed that on the 14th day of the experiment, the accumulative leaching losses of soil nitrogen in treatment with PSB were 4.68% lower than those in NH4NO3 treatment, while in the treatment with NJ1 and NJ2, the losses were 20.20% and 14.49%. The pot experiment showed that the biomass of flowering Chinese cabbage in treatment with the complex water-retaining agent increased from 10.33% to 34.44% on average than that in NH4NO3 treatment.
