摘要
引进10种不同规格的全生物降解膜在茎用莴苣上进行试验,研究其对产量的影响。结果表明:与普通聚乙烯地膜对照相比,除上海黑6外,其他降解膜对茎用莴苣产量的影响不显著,但有随着膜厚度的降低产量减少的趋势;不同厚度的降解膜,厚度越薄,降解速度越快;黑色降解膜进入诱导期的时间普遍要比白色降解膜早。综合地膜降解情况和茎用莴苣产量来看,云南白10全生物降解膜最适合早春茎用莴苣露地地膜栽培。
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.
