摘要:

【目的】研究可降解地膜的降解性能及其对玉米生长发育、土壤温度、干物质积累与产量的影响。【方法】采用不同可降解膜天壮(氧化-生物双降解生态地膜)、天野(全生物降解地膜)、弘睿(全生物降解地膜)、PED(聚乙烯吹塑农用地面覆盖薄膜)和CK,进行地膜栽培玉米对比试验。【结果】弘睿降解地膜的降解强度较其它2种降解地膜有优势,弘睿降解地膜和天野处理比天壮处理早10 d进入了2级降解并最终在玉米收获期都进入了崩裂期;天野和天壮处理与CK处理相比减产7.1%和12.44%,弘睿处理与CK处理在产量方面无明显差异。【结论】弘睿可降解地膜较适宜新疆北疆地区玉米生长需求。

Abstract:

【Objective】 The degradation performance, soil moisture content, maize growth and development, yield of biodegradable film were discussed.【Methods】 Tianye (Whole Biodegradable Film) and Hongrui (Whole Biodegradable Film), PED (Polyethylene Blown Agricultural Ground Cover Film) were applied and recorded as TZ, TY, HR and CK film to perform maize comparative experiments. 【Results】 The results showed that HR degradable film had advantages over other two kinds of degradable film in terms of explaining intensity. HR degradable film and TY degraded film entered the second degradable stage 10 days earlier than TZ treatment and eventually entered the disintegration stage in the maize harvest period. Compared with CK treatment, the yields of TY and TZ treatment were significantly reduced by 7.1% and 12.44%. There was no significant difference in yield between HR treatment and CK treatment. 【Conclusion】 HR degradable plastic film is more suitable for maize growth characteristics in northern Xinjiang.

Key words: maize; degradable plastic film; yield; degradation characteristics
