Effects of Water-Fertilizer Coupling on Yield and Quality of Flavor-Type and Common Greenhouse Tomatoes in North China

doi:10.7668/hbnxb.20196710

Abstract

Abstract:

To elucidate the regulatory effects of water-fertilizer coupling on fruit quality and taste substance accumulation in flavor tomatoes,greenhouse experiments were conducted using Yutianyou 6(premium flavor type)and 2442(common type)as test materials.Six water-fertilizer coupling treatments were established(W1F1:70%—75% ETc+180-90-150 kg/ha;W1F2:70%—75% ETc+240-120-200 kg/ha;W1F3:70%—75% ETc+300-150-250 kg/ha;W2F1:80%—85% ETc+180-90-150 kg/ha;W2F2:80%—85% ETc+240-120-200 kg/ha;W2F3:80%—85% ETc+300-150-250 kg/ha).The effects on yield,nutritional quality,sugar-acid components,and dynamic accumulation of soluble solids in greenhouse tomatoes were investigated.The results demonstrated that: both irrigation and fertilization exerted extremely significant effects on tomato yield.The W2 regime increased yields of Yutianyou 6 and 2442 by 22.3% and 19.6%,respectively,compared with W1.The highest yields were obtained under F3,reaching 33 720,33 480 kg/ha,respectively.Quality traits exhibited cultivar-specific responses.Vitamin C content was optimized in Yutianyou 6 under W1F2(0.383 mg/g)and in 2442 under W1F3(0.224 mg/g).Soluble protein accumulation was predominantly fertilizer-driven,peaking in Yutianyou 6 at W2F2(7.02 mg/g).Sugar-acid accumulation patterns varied between cultivars.Yutianyou 6 showed optimal glucose,citric acid,and malic acid accumulation under W2F2,with maximal fructose and sugar-acid ratio(8.326)achieved under W2F1.Conversely,2442 displayed weaker water responses,attaining its highest sugar-acid ratio(9.346)under W2F2.Soluble solids(Brix)displayed a rapid initial increase followed by stabilization,with W1F2 producing the optimal synergistic effect(peak 10.19% in Yutianyou 6)while conserving 12.5%—17.6% irrigation water and 20% fertilizer compared with W2F1.In conclusion,moderate water deficit combined with optimized fertilization can simultaneously enhance yield and quality.Yutianyou 6 is recommended for the high water-low fertilizer regime(W2F1),whereas 2442 is suited to the high water medium fertilizer regime(W2F2).
