摘要
研究了早熟灵对 5～ 7a生脐橙产量和品质的效应 ,3a的结果表明 ,8月中旬喷施 1次 30 0mg/L或2 0 0mg/L的早熟灵 ,与对照相比能明显提早果实着色 ,鲜果中维生素C含量提高 2 2 .2 8%和 1 5 .86 % ,可溶性固形物增加 4.5 5 % ,柠檬酸含量降低 30 .0 0 % ,固酸比提高 48.6 9%和 5 1 .6 % ,产量提高 2 3.7%和 2 5 .1 %
The effects of spraying Zaoshuling (a new formula of plant growth regulator) on yields and quality of Newhall Navel with 5 to 7 year old trees were studied. Results showed that the fruit coloring occurred earlier, and Vc increased 22.28% by 15.86%. Soluble solids content increased by 4.55%. Sitric acid content decreased by 30.00 %, soluble solids and acids ratio increased by 48.4% and 45.5%, yields increased by 21.13% and 25.07% respectively after spraying 300 mg/L or 200 mg/L Zaoshuling in mid August. \;
