塑料大棚草莓麻地膜覆盖效应研究

Effect of Bast Fiber Mulching Film on Strawberry in Plastic Greenhouse

为了探究麻地膜覆盖栽培在草莓上的应用效果,通过对比试验比较不同膜覆盖条件对草莓形态、糖度及产量的影响,进而为麻地膜在设施栽培中的应用提供理论依据。试验以“甜查理”为供试材料,设置麻地膜、塑料地膜和不覆膜3种种植方式,采用单因素随机区组排列方式开展田间试验。结果表明:相较于无膜,麻地膜覆盖能显著提高10 cm土层处土壤温湿度,土壤温度提高6.00%~41.72%,土壤湿度提高12.81%~77.25%;同时提高了草莓果实大小、单果重量及产量,其中果长提高0.37%~27.45%,果宽提高10.16%~39.27%,果厚提高1.70%~25.75%,单果重量提高2.56%~54.93%,且其糖度显著增加,达到2.66%~57.44%,产量增幅达到34.6%。

The purpose of this research was to explore the application effects of bast fiber mulching film cultivation on strawberry.And morphology,brix and yield were studied,which would provide theo-retical basis for the application of bast fiber mulching film in facility cultivation.Three mulching cultiva-tion methods including bast fiber mulching film,plastic film and no film were set up under a single factor random block design experiment on the cultivation bed of Tianchali.The results showed that compared with no film mulching,mulching with bast fiber mulching film significantly increased soil temperature and moisture by 6.00%—41.72%and 12.81%—77.25%,and also increased the fruit size,single fruit weight and yield of strawberry,of which the fruit length increased by 0.37%—27.45%,the fruit width increased by 10.16%—39.27%,the fruit thickness increased by 1.70%—25.75%,and the single fruit weight increased by 2.56%—54.93%,meanwhile,the brix significantly increased by 2.66%—57.44%,the yield increased by 34.6%.
