Technical studies on the solution to Shine Muscat viruses
In response to the frequent occurrence of virus diseases and serious harm to the tree and fruit of the Shine Muscat grapevines,different treatments with root fertilizer,root fertilizer+fo-liar spraying were carried out during the leaf-expansion stage,to explore the effects of different fer-tilizer treatments on the improvement of the virus disease and the enhancement of the yield and qual-ity.The results showed that the optimal control effect of the new leaf virus disease was achieved by root application of high nitrogen water-soluble fertilizer 10 kg+humic acid organic water-soluble fertilizer 5 kg per 666.7 m2,and leaf spraying of 5%amino oligosaccharide water 500 times+0.01%28 high brassinolide 1 500 times+seaweed organic water-soluble foliar fertilizer 1 000 times for three times,with an interval of 7 days once.Compared with the control root application of conventional organic water-soluble fertilizer 5 kg+balanced water-soluble fertilizer 5 kg per 666.7 m2,the development of new leaves was always at a lower level,the growth rate of new leaf area was at a higher level,and the quality and yield of grapes were significantly improved.
