Abstract:Ten kinds of full biodegradation films with different specifications were introduced and tested
on stem lettuce production.Their effects on yield were studied.The results showed that except ‘Shanghai
black 6’,the other degradable films had no significant effect on stem lettuce yield comparing with the ordinary
polyethylene film.But there was the tendency of yield decreasing along with the decrease of film thickness.
The thinner the film thickness was,the faster the degradation rate was.The time duration for black degradation
film entering into induction period was generally earlier than that of the white one.Comprehensively seen from
film degradation status and stem lettuce yield,full biodegradation film‘ Yunnan white 10’ was the most suitable
film mulching for stem lettuce cultivation in early spring.
