| 摘 要： | 研究0.2%噻苯隆可溶液剂提高‘脆皮’金桔产量和品质的效果,在金桔的幼果期和果实膨大期喷施不同质量分数(2、3、4、6 mg/kg)的0.2%噻苯隆可溶液剂,测定其对金桔产量和品质等指标的影响。与空白对照比较,喷施0.2%噻苯隆可溶液剂的金桔单株产量增加了16.5%~23%,果实质量增加10.2%~12.2%,果肉的可溶性物含量增加了5.9%~6.3%,维生素C含量增加了8.7%~9.3%,含糖量增加了7.9%~9.0%,可滴定酸含量下降了8.1%~13.5%。0.2%噻苯隆可溶液剂对金桔产量及品质有显著的提高和改善作用,当药液剂量达到4 mg/kg时,金桔的各项指标均达到较高水平,且与最大值无显著差异,因此推荐生产中使用0.2%噻苯隆可溶液剂的适宜浓度为3~4 mg/kg。

| Abstract: | This paper aims to study the effects of thiabendazole 0.2% SL on the yield and fruit quality of kumquat. A series of concentrations of thiabendazole 0.2% SL (2, 3, 4, 6 mg/kg) were sprayed at the young fruit and fruit expansion stage of kumquat to assess the relevant indicators such as yield and quality. Compared with the control, the results showed that the yield of fruit increased by 16.5%-23%, the fruit quality increased by 10.2%-12.2%, the soluble content of kumquat pulp increased by 5.9%-6.3%, the content of vitamin C increased by 8.7%-9.3%, the sugar content increased by 7.9%-9.0%, while the titratable acid content decreased by 8.1%-13.5%. Thiabendazole 0.2% SL could significantly improve the yield and quality of kumquat. At 4 mg/kg dosage, the indicators of kumquat could reach a high level, and show no significant difference from the maximum value. So the recommended concentration of thiabendazole 0.2% SL for production is 3-4 mg/kg. |
