含钙镁硅硝基复合肥对纽荷尔脐橙增产提质效应的研究

Study on the Effect of Nitro Compound Fertilizer Containing Calcium,Magnesium and Silicon on Increasing Yield and Improving Quality of New Holland Navel Orange

为了探究含钙镁硅硝基复合肥对赣南脐橙产量及品质的影响,以纽荷尔脐橙为对象,开展了田间小区试验。试验共设3个处理,分别为不施肥(T1)、习惯施肥(T2)和施用含钙镁硅硝基复合肥(T3)。结果表明:T3处理可提高脐橙的挂果数、单果质量及果实横径,其中T3处理的挂果数比T2处理的显著提高15.62%,果实横径属于优质果范畴;T3处理还可改善果实品质,其中可溶性固形物含量比T2处理的显著提高15.50%,维生素C含量显著提高15.90%,可滴定酸含量显著降低39.09%,糖酸比、固酸比和可食率都有一定程度的提升。相较于习惯施肥,施用含钙镁硅硝基复合肥能提高脐橙的产量和品质。

In order to investigate the effect of nitro compound fertilizer containing calcium,magnesium and silicon on the yield and quality of Gannan navel oranges,a field plot experiment is conducted with New Holland navel oranges.Three treatments are applied:no fertilization(T1),habitual fertilization(T2)and application of nitro compound fertilizer containing calcium,magnesium and silicon(T3).The results show that T3 treatment can improve the number of fruits hung,single fruit weight and fruit diameter of navel oranges,in which the number of fruits hung in T3 treatment is significantly higher than that in T2 treatment by 15.62%,and the fruit diameter can be listed to the category of high quality fruits.T3 treatment can also improve the fruit quality,in which the soluble solids content is significantly higher than that in T2 treatment by 15.50%,Vitamin C content is significantly higher by 15.90%,titratable acid content significantly decreased by 39.09%,and the sugar-acid ratio,solid-acid ratio and edible rate are all improved to some extent.Compared with habitual fertilization,the application of nitro compound fertilizer containing calcium,magnesium and silicon improves the yield and quality of navel oranges.
