Abstract:

In order to investigate the effects of different mulching films on crop growth, soil fertility, and pollutant residues, three different mulching treatments (white non-degradable mulching, F; black degradable mulching, H; brown degradable mulching, Z)and non-mulching (CK)were applied to taro plants. Surface soil temperature at the seedling stage, taro yield, and nutrient, microplastic, and phthalate ester (PAE)content of soil were analyzed. The results showed that the application of mulching film increased taro yield by 10.20%~29.61%, in the order of F > H > Z > CK. The residue of mulching film was the highest in F treatment. Moreover, the disintegration rate in Z treatment was faster than that in H treatment. Both microplastic and PAE residues were detected in all mulching treatments, but the difference across treatments was not significant. Microplastic and PAE content was in the range of 260~393 n·kg^-1 (dry weight)and 0.87~1.17 mg·kg^-1, respectively. In conclusion, biodegradable mulching films can effectively reduce white pollution of soil. Black degradable mulch is better than brown degradable mulch in terms of increasing taro yield.
