摘要
以塑料薄膜和无纺布为试材,采用"无纺布外覆盖+二道膜覆盖"与"二道膜覆盖"2种覆盖形式研究冬季单体大棚的保温效果。结果表明:"无纺布外覆盖+二道膜覆盖"形式夜间保温效果明显优于"二道膜覆盖"形式,保温效果4.9℃。无纺布外覆盖后,大棚温度低于5℃的时间为1.03～5.49h,高于10℃的时间却有2.58～8.59h,棚角下部温度均高于棚角上部温度。"无纺布外覆盖+二道膜覆盖"形式下,番茄植株生长健壮,产量较"二道膜覆盖"提高9.08%～35.24%。
Film and non-woven fabric were used as test material,the heat preservation effect of monomer plastic greenhouse in winter was studied by covering with ＇non-woven fabric＋ the second film＇and＇the second film＇.The results showed that the insulation effect of covering with＇non-woven fabric＋the second film＇at night was significantly better than covering with＇the second film＇,which can improve the insulation effect of 4.9℃.The temperature below 5℃ in greenhouse lasted for 1.03-5.49 hours,while temperature higher than 10℃ in greenhouse lasted for 2.58-8.59 hours by covering with＇non-woven fabric＋ the second film＇.The bellowing temperature of corner in greenhouse was higher than the top temperature.Compared with covering by＇the second film＇,the tomato plants presented strong growth vigor,and the production was increased 9.08% - 35.24% by covering with＇non-woven fabric＋ the second film＇.
