塑料大棚内麻地膜覆盖草莓效应的初步研究

为明确麻地膜在大棚内覆盖栽培对作物的影响特点，在大棚和露地同时进行不同地膜覆盖草莓的比较试验。结果表明：麻地膜在大棚内覆盖的增温、保水效应比在露地大，能够提早草莓开花结果，显著提高产量。大棚和露地不同种植环境与不同覆盖处理间的互作效应极显著。麻地膜在大棚内的增产效果更好，比无覆盖增产12.8%，比塑料地膜增产1.73%。麻地膜比无覆盖在大棚内的增产幅度要比在露地多增产4.3%。

Preliminary Study on Effects of Coverage by Bast Fiber Mulching Film on Strawberry in the Greenhouse

In order to be clear about the influence characteristic of the bast fiber mulching film covering crop in greenhouse,the comparison test of the strawberries covered by different films both in greenhouse and open field was carried out.The research results showed that bast fiber mulching films in the greenhouse increased the soil temperature greatly and enhance the water retaining capacity largely,which were better than that on the field.Comparing with covering on the field,blossom and bear fruit in the greenh...
