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 car-ried 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 col-oring 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 diseas-es and pests such as canker,gray mold,aphids,thrips,scale insects,red spiders,etc.
