COS——Tarocco Blood Orange
Experimental groups：
1:50 ppm COS solution sprayed 6 times;
2:50 ppm COS solution sprayed 2 times, Marine oligosaccharides potassium 750 times liquid sprayed 4 times;
3: Amino acid water soluble fertilizer 600 times liquid sprayed 6 times
4:CK (clear water).
Result：Compared with the control group：
Treatment with 50ppm COS increased the single fruit weiht、the average yield of late-maturing tarocco blood orange nucellar line and the content of soluble solids by5.7%、13.9% and 0.5% respectively.
