Abstract：Using Aisuo 301 series cherry tomato as the test material,six different heating methods including hanging and laying were applied,with no heating as the control,to study the effects of different heating methods using graphene poly-mer nano energy heating sheet on the growth and fruiting of soilless cultivated cherry tomato in glass greenhouse.The results showed that heating with graphene heating sheets had a certain promoting effect on tomato plant growth,flower-ing,fruiting,and fruit yield and quality.After installing graphene heating sheets,the tomato plant height(total plant height 236.21-260.73 cm),number of fruit clusters per plant(9.41-9.90 clusters),and single fruit mass(10.02-11.30 g)all increased significantly,and the yield(734.13-871.47 g)was significantly improved.Among them,the T1 combination suspension with two strips performed better in terms of total leaf number,total fruits,number of flowering clusters,and number of fruit clusters,but it had the highest electricity consumption(9 963.36 kW·h)and cost(10 606.68 yuan).The heating method of laying graphene heating sheets under coconut coir strips(T6)consumed the lowest power and had a significant effect on increasing yield,with a 13.23％increase in single fruit mass and a 18.73％increase in total mass.This method demonstrated the advantages such as fast fruit ripening,good yield increasing effect,5-8 years of long service life,and low electricity cost(489.14 yuan),high cost-effectiveness,and significant energy savings.In summary,the heating element laid under coconut coir strips is suitable for promoting and applying graphene heating methods for soilless cultivation of cherry tomato in greenhouse.
