Abstract The results of this experiment in 3 years are as follows: Pot experiment. The residual quantity of broken plastic film at 90～720kg/ha has no effect on the plant height, stem thickness and leaf area. The value of T/R ratio increased as the incerase of residual quantity of broken plastic film, but the correlation is not significant. The residual quantity of broken plastic film could effect the absorbability of plant to P_2O_5. Field plot experiment The variation of early yield, total yield and fruit numbers a...
