用糖、硼砂、CaCl2和DA-6的混合液处理生长在瘦瘠和肥沃土壤上的早钟6号枇杷(EriobotryaLindl.).结果表明:1)混合试剂处理可提高果实可溶性固形物的含量,不影响单果重,同时能显著增加单位面积的果穗数和产量;2)瘦瘠土壤上,晚处理果穗的产量和产值均高于早处理的果穗;3)肥沃土壤上,晚处理果穗的产量高于早处理果穗的产量,而产值则低于早处理的果穗.

Loquat（Eriobotrya Lindl.cv.＂Zaozhong No.6＂） plants,grown on the poor soil and fertile soil,were sprayed with mix aqueous solution of the sugar,borax,CaCl2 and DA-6 on November and next January respectively.The results showed that： 1） All treatments increased content of total soluble solids of the fruits,had no effect to the fruit weight,but remarkably increased the fruit spikes on unit soil area,increased fruit output.2） On the poor soil,the later treatment could have higher output and value than earlier treatment 3） On the fertile soil,the later treatment had the highest output,but the earlier one had the highest value, which could have relation to having the higher unit price on earlier market.
