三种肥料增效剂复配对樱桃番茄生长和品质的影响

Effect of Mixed Application of Three Fertilizer Synergists on Growth and Quality of Cherry Tomato

以"金玲珑"番茄品种为试材,研究了复硝酚钠、DA-6、α-萘乙酸钠3种肥料增效剂复配后结合水肥一体化对连栋温室樱桃番茄生长和果实品质的影响。结果表明:3种肥料增效剂复配结合水肥一体施用,各处理与对照相比,均能促进樱桃番茄的株高,尤其是在生长前期,其中8mg·L^(-1)复硝酚钠+4mg·L^(-1)α-萘乙酸钠的处理对株高促进作用最明显,5mg·L^(-1) DA-6+8mg·L^(-1)复硝酚钠的处理次之。8mg·L^(-1)复硝酚钠+4mg·L^(-1)α-萘乙酸钠的处理对樱桃番茄的基部茎粗有明显促进作用,对樱桃番茄坐果数、坐果率、单果质量的影响差异性较小,对产量没有影响。各处理对樱桃番茄的维生素C含量有明显的增加,其中5mg·L^(-1)DA-6+4mg·L^(-1)α-萘乙酸钠,5mg·L^(-1)DA-6+8mg·L^(-1)复硝酚钠,8mg·L^(-1)复硝酚钠+4mg·L^(-1)α-萘乙酸钠相比较对照分别提高35%、119%、139%。

Cherry tomato ＇Jinlinglong＇ was used as test material, the effect of mixed application of sodium nitrophenolate, DA-6,and NNA combined with integrative water and fertilizer on the growth and fruit quality of cherry tomato were studied under glass-greenhouse. The results showed that three kinds of fertilizer synergistic mixtures using a combination of water and fertilizer,could promote cherry tomato plant height, especially in the early growth stage,which 8 mg ·L^-1 compound sodium nitrophenolate＋4 mg ·L^-1 alpha-naphthyl acetate treatment on line high the most significant role in promoting,5 mg ·L^-1 DA-6＋8 mg ·L^-1 compound sodium nitrophenolate treatments. Three kinds of fertilizer synergistic mixture on base stem diameter of cherry tomato only 8 mg ·L^-1 compound sodium nitrophenolate ＋ 4 mg·L^-1 alpha-naphthyl acetate obvious role in promoting, on cherry tomato fruit number, fruit rate, fruit weight difference was small,did not affect to yield. Each treatment of cherry tomato vitamin C content increased significantly, among them 5 mg ·L^-1DA-6＋4 mg ·L^-1 alpha-naphthyl acetate, 5 mg ·L^-1DA-6＋8mg·L^-1 sodium nitrophenolate,8 mg ·L^-1 sodium nitrophenolate＋4 mg ·L^-1 alpha-naphthyl acetate comparing with the control group were increased by 35 %,119 %, 189 %.
