全生物降解膜和小拱棚对早春设施芦笋的覆盖效应研究

Effects of Full Biodegradable Mulching Films and Small Arch Shed Coverage on Asparagus in Early Spring

为探讨全生物降解膜和小拱棚覆盖对早春设施芦笋的影响,本研究以丰岛1号芦笋为材料进行全生物降解膜覆盖与全生物降解膜+小拱棚覆盖比较试验。试验结果表明,与小拱棚覆盖相比,8μm×100 cm全生物降解膜覆盖和8μm×100 cm全生物降解膜+小拱棚覆膜方式能提前2 d采收,早春产量明显增加,增产63.48%和88.05%,商品笋增产60.93%和84.23%,优质笋增产32.16%和27.75%,667 m^(2)总收益增加106.44%和93.68%。综上,认为8μm×100 cm的全生物降解膜可优先用于早春设施芦笋的促早产增产生产。

In order to explore the effects of full biodegradable mulching films and small arch shed coverage on asparagus in early spring, the comparative test was carried out with Fengdao No.1 asparagus as the material. The result showed that compared with the small arch shed, 8 μm×100 cm full biodegradable mulching film and 8 μm×100 cm full biodegradable mulching film +small arch shed could harvest 2 days earlier, the yield in early spring significantly increased by 63.48%and 88.05%, the yield of commercial asparagus increased by 60.93% and 84.23%, the yield of high-quality asparagus increased by 32.16% and 27.75%, and the total income increased by 106.44% and 93.68%. In conclusion, 8 μm×100 cm fully biodegradable mulching film cloud be preferentially used for promote early emergence and increase the total and marketable yield of asparagus in early spring in greenhouse.
