施用不同叶面肥对瓯柑果实品质的影响

摘要

Effects of four kinds of foliar fertilizers ( high performance calcium, boron fertilizer, calcium nitrate and rare earth fertilizer) on fruit quality of Mandarinorange( Citrus suavissima. Hort. ex Tanaka) were studied based on plants of five years old. The results showed that the contents of total soluble solids, soluble sugar and juice yield of fruit increased, while the titratable acid decreased following all foliar fertilizer treatments. Rare earth fertilizer showed the best effect than boron fertilizer and high performance calcium. Treatment of fruit with different concentrations of high performance calcium diluted 600 times showed the highest quality.%以5年生瓯柑为材料,研究高效钙、硼肥、硝酸钙、稀土肥等4种叶面肥对果实品质的影响.结果表明,喷施4种叶面肥均可不同程度提高瓯柑果实可溶性固形物、可溶性糖含量和出汁率,降低可滴定酸含量.其中以稀土肥处理效果最佳,其次为高效钙与硼肥.不同稀释倍数高效钙处理试验表明,果实品质以稀释600倍的处理效果最佳.
