Abstract:

In order to evaluate the application value of polyolefin(PO)film for cucumber growth in solar greenhouse,a greenhouse coated with ethylene-vinyl acetate(EVA)film was served as the contrast.The influence of PO film coating on temperature and illumination environment and yield of cucumber(Cucumis sativus L.)in solar greenhouse were studied.The results showed that the light intensity in PO solar greenhouse was increased about 20-280μmol·m-2·s-1 .As a result,the daily average air and soil temperature were increased 0.2-2.0 ℃,0.3-1.5 ℃,respectively compared with the EVA solar greenhouse.There were no significant effects on carpopodium length and fruit diameter.However,the fruit length were increased significantly by PO film coating.The commercial rate of cucumber fruit were increased about 10 percentage points,which result in the increase of cucumber yield.Compared with the yield of cucumber in EVA solar greenhouse,the earlier,middle and later yield in PO solar greenhouse were increased about 52.0%,27.2% and 58.6%,respectively.So the acre yield and income were increased about 43.4% and 39.9%,respectively,and the input-output ratio were increased
about 129%.PO film had a good application prospective in protected vegetable production in northern China in winter and spring.

摘要:

为探究 PO(polyolefin,聚烯烃)膜在设施黄瓜生产中的应用效果,以覆盖 EVA(ethylene-vinyl acetate,醋酸乙烯)膜的日光温室为对照,研究了覆盖 PO 膜对日光温室温光环境和黄瓜产量的影响。结果表明:与对照相比,PO 膜覆盖能使日光温室内的光照强度提高 20~280 μmol·m-2·s-1,使温室气温和地温分别升高 0.2~2.0 ℃和 0.3~1.5 ℃ ;对黄瓜瓜把长和瓜直径没有显著影响,但显著增加了黄瓜瓜长,且使黄瓜商品瓜率提高 10 个百分点;使每 667 m2 黄瓜前期、中期、后期产量和总产量均明显增加,分别比对照提高 52.0%、27.2%、58.6% 和 43.4%,每 667 m2 收入提高 39.9%,投入产出比提高129%。综上,PO 膜在我国北方冬春季节设施黄瓜生产中具有良好的应用前景。
