我省柑桔果园多处于丘陵红壤上，不少果园肥力低、酸度大、土壤供肥能力弱，因而柑桔产量低，品质差。从施肥角度来讲，除施肥量不适当，氮、磷、钾比例失调外，还与忽视施用石灰及土壤改良等有关。为了探索施用石灰对酸性红壤桔园产量和品质的影响，我们连续4年进行了酸性桔园
Citrus orchards in our province are mostly located in the hilly red soil. Many orchards have low fertility, large acidity and weak soil fertility. Therefore, citrus yield is low and quality is poor. From fertilization point of view, in addition to inappropriate amount of fertilizer, nitrogen, phosphorus and potassium imbalance, but also ignore the application of lime and soil improvement and so on. In order to explore the application of lime on the yield and quality of acid red soil orange garden, we conducted four consecutive years of orange garden
