为验证生物有机肥与长效复合肥配施对提高柑橘产量、品质及改良土壤的效果,以塔罗科血橙为试验对象,开展了田间小区试验。试验共设习惯施肥(CK)、单施长效复合肥(T1)和生物有机肥与长效复合肥配施(T2)等3个处理。结果表明:T2处理的柑橘产量较CK处理的提高16.29%;T2处理的柑橘果肉中全钾、还原糖、维生素C含量最高;T2处理的土壤中交换性钙含量显著提高,碱解氮、有效磷、有机质、有效铜、有效锌等含量均高于CK和T1处理的。生物有机肥与长效复合肥配施,具有改善土壤理化性状及提高柑橘品质和产量的效果。
In order to verify the effect of combined application of bio-organic fertilizer and long-lasting compound fertilizer on improving citrus yield, quality and soil improvement, a field plot experiment is carried out with Taroco blood orange as the test object. There are three treatments: customary fertilization (CK), single application of long-lasting compound fertilizer (T1) and combined application of bio-organic fertilizer and long-lasting compound fertilizer (T2). The results show that the citrus yield of T2 treatment is 16.29% higher than that of CK treatment. The citrus pulp of T2 treatment has the highest content of whole potassium, reducing sugar and vitamin C. The exchangeable calcium content in the soil treated with T2 is significantly increased, and the content of alkali-hydrolyzable nitrogen, available phosphorus, organic matter, available copper, available zinc and so on are higher than that of CK and T1 treatment. The combination of bio-organic fertilizer and long-lasting compound fertilizer has the effect of improving soil physicochemical properties and enhancing citrus quality and yield.
