过量施用化肥对设施番茄光合特性及品质的影响
The Impact of Excessive Fertilizer Application on the Photosynthetic Characteristics and Quality of Protected Tomato Crops
摘要
Abstract
Currently,excessive fertilizer application is a common issue in greenhouse tomato production.To investigate the effects of different fertilizer application levels on tomato yield and quality,a pot experiment was conducted with four treatments:no fertilizer(CK),moderate fertilizer application(T1),double over-appli-cation(T2),and triple over-application(T3).The study examined the impacts of these treatments on growth indices,photosynthetic parameters,yield,and quality indicators.Results showed that compared to T1,T3 sig-nificantly inhibited tomato plant growth.T2 achieved higher total yield than T1 but without significant yield im-provement,while T3 significantly reduced total yield.T3 treatment significantly decreased leaf net photosyn-thetic rate and transpiration rate.Additionally,T3 significantly reduced single fruit weight,increased fruit shape index,and markedly decreased fruit firmness.Excessive fertilization in greenhouse tomato production adversely affects plant growth,photosynthesis,yield,and quality.The findings provide a theoretical basis for rational and reduced fertilization in greenhouse vegetable cultivation.关键词
