摘要
以甜椒品种"红罗丹"为试材,以传统内添加型EVA膜为对照,研究了涂覆膜和试验型内添加EVA膜的透光保温性及其对甜椒生长、环境及产量的影响。结果表明:涂覆膜和试验型内添加EVA膜的透光性及保温性均高于传统内添加EVA膜;试验型内添加EVA膜的月平均气温、地温均最高,保温增温效果最好;涂覆膜的透光性能最好,气温日变化剧烈;涂覆膜和试验型内添加EVA膜分别比对照增产23.3%和10.2%。
Taking the sweet pepper variety ＇ Red Rodin~ as test material,add to the traditional EVA film for the contrast, transmittance insulation of the coating film and add to the test type EVA film on sweet pepper growth environment and yield were studied. The results showed that light transmission and thermal insulation of the coating film and the test type added to EVA film were better than conventional added EVA film. The monthly average temperature and ground temperature insulation warming effect of the test type added to EVA film were maximum. The coating lamination had the best light transmission properties, and the daily temperature changed rapidly. The yield of adding coated lamination and test type EVA film increased by 23. 3% and 10. 2% than the contrast,respectively.
