摘要： 为探讨全生物降解地膜对土壤理化性质及早春马铃薯效益的影响,引进10种全生物降解地膜开展相关试验。结果表明,全生物降解地膜能够提高土壤整体性能,且对早春马铃薯具有增产提效作用。其中,白色全生物降解地膜的降解速度相对更快,作物产量相对较高;而黑色全生物降解地膜有效提升了整体土壤肥力以及土壤酶活性。马铃薯收获时全生物降解地膜基本处于开裂期,可直接机械翻耕整地,不产生白色污染。与普通地膜相比,本试验所有全生物降解地膜每667 m2平均产值增加5.2%,比较效益平均增加6.4%,其中覆盖8 μm白色全生物降解地膜的耕地经济效益最高。本试验结果表明,白色全生物降解地膜在露地早春马铃薯的应用上具有广阔的推广应用前景。

Abstract:

To examine the effects of full biodegradable mulch films on soil physicochemical properties, as well as the benefits for spring potato cultivation, experiments were conducted using 10 different types of full biodegradable mulch films. The results showed that the full biodegradable mulch film can improve the overall performance of the soil and had a yield-increasing and efficiency-improving effect on spring potatoes. Among them, the white full biodegradable mulch film had a relatively faster degradation speed and a relatively higher crop yield; while the black full biodegradable mulch film effectively improved the overall soil fertility and soil enzyme activity. At the time of potato harvest, the full biodegradable mulch film was basically in the large cracking period, it could be directly mechanically turned over and cultivated without producing white pollution. Compared with ordinary films, the average yield of all the full biodegradable mulch films covered in experiment increased by 5.2% per 667 m2, and the average economic benefit increased by 6.4% per 667 m2, among which the highest economic benefit was obtained under 8 μm white full biodegradable mulch film. The results of this experiment showed that the white full biodegradable mulch film has broad prospects for popularization and in the cultivation of early spring potatoes in open fields.
