摘　　要：目的:探究石墨烯电热膜不同加温方式对番茄生长和结果的影响。方法:以‘黄金美人’番茄为试材,采用种植槽两侧分别铺设10 cm、15 cm石墨烯电热膜两种加温方式,以空气源热泵加温为对照,研究了不同石墨烯电热膜加温方式对基质温度、番茄叶片叶绿素含量、番茄产量和果实品质的影响。结果:种植槽两侧铺设10 cm石墨烯电热膜加温能够有效增加基质温度、番茄单株产量和单果重量,但降低了植株顶端的幼嫩组织叶片的叶绿素含量;种植槽两侧铺设15 cm石墨烯电热膜加温显著提高了基质温度、番茄植株中下部叶片的叶绿素含量、番茄β-胡萝卜素和可溶性蛋白含量。结论:冬季在设施番茄种植槽两侧铺设石墨烯电热膜可以促进番茄生长和产量增加,该方法具有一定的推广价值。Objective:To explore the effect of different heating methods of graphene electrothermal film on tomato growth and fruiting.Methods:With‘Golden Beauty’tomato as the test material,10 cm and 15 cm graphene electrothermal films were laid on both sides of the planting groove,respectively.The effects of different heating methods of graphene electrothermal film on substrate temperature,tomato leaf chlorophyll content,tomato yield and fruit quality were studied with air source heat pump heating as the control.Results:Heating with 10 cm graphene electrothermal film on both sides of the planting groove could effectively increase the substrate temperature,yield per plant and fruit weight,but reduce the chlorophyll content of the young tissue leaves at the top of the plant.Substrate temperature,chlorophyll content,β-carotene and soluble protein content of tomato leaves in the middle and lower parts of tomato plants were significantly increased by heating with 15 cm graphene electrothermal film on both sides of the planting groove.Conclusion:In winter,laying graphene electrothermal film on both sides of tomato planting tanks in facilities can promote tomato growth and yield increase,and this method has certain popularization value.
