众所周知，塑料地膜可以提高许多蔬菜的产量，特别是早季产量，这很可能是通过提高土壤温度和湿度以及抑制杂草生长来实现的。土壤表面覆盖减少侵蚀，减少蒸发，防止雨滴影响，并增加团聚稳定性。以下田间试验于2008/09和2009/10在波兰克拉科夫Mydlniki试验农场进行。对覆盖可生物降解无纺布（Bionnole 100 g·m -2 和 IBWCH 75 g·m -2 ）薄膜的冬韭菜和洋葱进行了评估，以估计几种土壤物理和化学性质的变化。该实验揭示了处理与土壤中湿骨料含量之间的相互作用。生物膜覆盖略微增加了大聚集体（4.0-2.5毫米）的数量，并降低了小尺寸大聚集体（0.50-0.25毫米）的百分比。我们还观察到处理后土壤持水量增加的趋势。所得结果表明，使用可生物降解薄膜作为覆盖物可以替代世界上广泛使用的传统塑料薄膜。
It is well known that plastic mulch film increases the yield of many vegetables, in particular the early season yield, most likely by increasing soil temperature and moisture, and inhibiting weed growth. Soil surface covering decreases erosion, reduces evaporation, protects against raindrop impact, and increases aggregate stability. The following field experiment was carried out at the experimental farm in Mydlniki in Krakow, Poland in 2008/09 and 2009/10. Winter leek and onion covered by biodegradable nonwoven (Bionnole 100 g·m -2 and IBWCH 75 g·m -2 ) film were assessed to estimate the changes in several physical and chemical soil properties. The experiment revealed the interaction between treatments and wet-aggregate content in soil. The biofilm covering slightly increased the amount of large aggregates (4.0-2.5 mm) and decreased the percentage of small sized macroaggregates (0.50-0.25 mm). We also observed a trend in the increase of water capacity in soils following treatments. The obtained results suggest that the use of biodegradable film as covering could be an alternative to the traditional plastic films widely used in the world.
