天达2116植物营养液对柑橘果实产量和质量的影响

Effect of Tianda 2116 Plant Nutrient Solution on Yield and Quality of Citrus Fruit

以纽荷尔脐橙为试材,用天达2116植物营养液在不同时期进行叶片施用,树干涂抹和灌根等措施的田间肥效试验,结果表明天达2116植物营养液促进了柑橘枝梢生长发育,在怀化橘园单产比0.3%磷酸二氢钾和清水两个对照分别提高了18.53%和37.25%,在永顺橘园单产比0.3%磷酸二氢钾和清水两个对照分别提高了12.63%和21.05%。天达2116提高了果实可溶性总糖、可溶性固形物、Vc含量。怀化橘园施用天达2116与清水对照相比,全氮、全钾、全钙和全镁含量降低了,全磷含量提高了,永顺橘园全氮和全钾含量降低了,而全磷和全钙含量提高了,全镁含量没有差异。

Using Newhall navel orange as materials, plant nutrient solution Tianda 2116 was applied to blade root, trunk daub and measures in different periods in the field to conduct the fertilizer experiment. The results showed that the shoot of navel orange trees treated with Tianda 2116 grew better than that of treated with KH2PO4 and water. Treated with Tianda 2116, the fruit soluble sugar, soluble solids content, Vc improved. Tianda 2116 decreased some kinds of leaves nutrition, improved the output, and quality of citrus fruit.
