摘要
[目的]为了提高日光温室冬季保温性能,克服冬季亚低温,促进作物生长。[方法]应用二层幕系统,分析温室内番茄生育期、生长势、环境因子、果实性状及产量等指标。[结果]应用二层幕系统后,冬春季节可提高日光温室内平均气温0.6~1.2℃,最高可提高1.7℃;提高平均地温0.2~0.6℃,最高可提高0.8℃;增产13.14%。[结论]应用二层幕系统可明显提高日光温室保温性能。
[Objective]The aim was to improve heat preservation performance of heliogreenhouse in winter,to overcome facilities winter low temperature,and to promote crop growth.[Method]Two-layer curtain system and normal system were compared,by analyzing traits containing the growth period,growth potential,environmental shadow,fruit characters and yield.[Result]During the winter and spring,the twolayer curtain system could improve 0.6~1.2℃of temperature in heliogreenhouse in the average,the highest could be increased by 1.7℃;the average ground temperature could be increased by 0.2~0.6℃,and the maximum increase was 0.8℃.The yield could be increased by 13.14%.[Conclusion]The two-layer curtain system could obviously improve the thermal insulation performance of heliogreenhouse.
