摘要: 为验证喷施石硫合剂对沃柑果实着色的效果,在广西南宁市武鸣区城厢镇开展石硫合剂不同处理的试验。结果表明,在沃柑成熟转色关键期(12月30日)喷施石硫合剂对促进沃柑转红和着色有显著促进作用,对促进转红和着色效果最显著的均是单次喷施石硫合剂1.2波美度,红度值a*比对照(CK)提升了15.24%,柑橘综合着色指数CCI比CK提升了40.07%,均达极显著差异水平。单次喷施石硫合剂0.8波美度,a*和CCI分别比CK提升了11.67%和32.31%。所有喷施石硫合剂的处理均表现出对转红和着色有提升效果。经过田间观察,石硫合剂还对溃疡病、灰霉病、蚜虫、蓟马、蚧壳虫、红蜘蛛等病虫害有良好防效。

Abstract: In order to verify the effect of spraying lime sulfur on the fruit coloring of orah, different treatments of lime sulfur were carried out in Chengxiang Town, Wuming District, Nanning City, Guangxi Province. The results showed that in the key period of maturity and color transformation(December 30th), the spray of lime sulfur had a significant effect on promoting the red transformation and coloring of orah. A single spray of lime sulfur 1.2 Baume degree had the most significant effect on promoting the red transformation and coloring, and the redness value a* increased by 15.24% compared with CK. The overall coloration index CCI of orah was increased by 40.07% compared with CK, both of which reached the level of extremely significant differences. After a single spraying of 0.8 Baume degree, a* and CCI increased by 11.67% and 32.31% respectively compared with CK. All treatments sprayed with lime sulfur showed an improvement effect on reddening and coloring. According to field observation, the lime sulfur also had good control effect on diseases and pests such as canker, gray mold, aphids, thrips, scale insects, red spiders, etc.
