摘要
为了明确可降解膜在马铃薯生产上的应用效果。本研究选择7个可降解膜开展田间试验和填埋试验,分析不同覆膜处理对马铃薯产量和降解膜降解性能的影响。结果表明覆膜处理较裸地处理可增产4.35%~14.62%,有4个降解膜较普通地膜增产1.48%~7.01%,但增产效果不显著(P>0.05)。在整个生育期地温呈现先升高后降低的变化趋势,5月和6月,覆膜较裸地分别提温0.42~1.29℃和0.39~1.09℃;7月,普通地膜较其他处理地温高0.52~1.36℃。所有降解膜于覆膜后12~22天进入诱导期,收获时均处于大裂期。在填埋1年后,4个全生物降解膜出现不同程度的降解,3个氧化生物降解膜未出现降解现象。试验表明可降解膜对马铃薯产量和地温的影响与普通地膜基本一致,虽然当年降解速度较慢、降解程度低,但从长远看可以推广利用,而且在当地建议推广使用T1降解膜。
To clarify the application effect of degradable film in potato production,in this study,7 kinds of degradable film were selected to carry out field and landfill experiments to analyze the effects of different film mulching treatments on potato yield and film degradation performance.The results showed that the potato yield of film mulching treatment was 4.35%-14.62%higher than that of bare ground treatment,and the potato yield of 4 degradable film treatments was 1.48%-7.01%higher than that of common film mulching,but the effect was not significant(P>0.05).In the whole growing period,the soil temperature increased first and then decreased.In May and June,the soil temperature of film mulching treatment was 0.42-1.29℃and 0.39-1.09℃higher than that of bare ground treatment respectively,and in July,the soil temperature of common film mulching was 0.52-1.36℃higher than that of other treatments.All degradable films entered the induction period 12 to 22 days after mulching,and all of them were in the big split period at harvest time.After one year of landfill,the 4 kinds of whole biodegradable film were degraded at different degrees,and the 3 kinds of oxidized biodegradable film were not degraded.The results showed that the effect of degradable film on potato yield and soil temperature was basically the same as that of common film.Although the degradation rate of degradable film was slow and the degradation degree was low of the very year,it could be popularized and used in the long run.T1 degradation film is recommended to be popularized locally.
