土壤调理剂在桃上应用效果的研究

为探讨土壤调理剂对桃园土壤、产量和品质的影响及适宜用量,在桃园设计不同用量处理,分析了土壤调理剂对产量、品质、土壤理化性状等的影响。试验结果表明:施用土壤调理剂提高了桃产量,每公顷用量1125 kg时产量最好,比对照提高了24.98%;施用土壤调理剂提高了桃单果重、可溶性固形物和总糖含量;土壤调理剂提高了桃园土壤p H值、有机质、阳离子交换量、碱解氮、速效磷、速效钾、交换性钙、交换性镁、有效锌和有效性铜的含量。综合效果,每公顷施用1125 kg最为适宜。

Application Effect of Soil Conditioner on Peach

To study the effect of soil conditioner on peach soil, peach yield and quality and the appropriate application amount, different application amounts were conducted to analyze the influences of soil conditioner on peach yield, quality and soil physicochemical properties. The results showed that the application of soil conditioner improved the yield of peach, and the highest yield was obtained when the application amount was 1125 kg/hm2, which increased by 24.98% compared with that of CK. The application of soil conditioner increased single weight, soluble solids content and total sugar content of peach, as well as the pH value, organic matter, CEC, available nitrogen, available phosphorus, available potassium, exchangeable calcium, exchangeable magnesium, effective zinc, effective manganese and effective copper content of soil. The appropriate amount of soil conditioner was 1125 kg/hm2.
