Abstract:
Using Mater-Bi which is biodegradable film and PBS film which is completely biodegradable film as test materials，effect of landfill and film mulching test on the degradation characteristics and application in processing tomato farmland were discussed，in order to realize the biodegradable film instead of the ordinary film to solve the problem of Xinjiang agricultural plastic film pollution.The results showed that,the Mater-Bi membrane degradation of the induction period was about 45 days，the PBS induction period was 30 days,after 90 days landfilled in the fields，degradation rate weight of Mater-Bi was 96.3%，PBS membrane degradation rate was 44.45%，both had good biodegradability in soil；After partial degradation of two kinds degradable film，the temperature of the 0-25 cm soil layer was less than ordinary film，Mater-Bi black degradable film temperature was the lowest；two kinds of degradable film enhanced the maturity and fruit number per plant of the processing tomato,but the single fruit weight and yield decreased，yield reduced by 2.16% of Mater-Bi membrane treatment，PBS treatment decreased by 7.08%，if matching the suitable cultivation measures and prolonging the degradation of the induction period，application effect of biodegradable mulch film would be better．
