Abstract: Adopt yuhualing into the control longan chongshao, Mainly through the leaves to absorb organic nutrition, And to enhance the effectiveness of leaf phorosynthesis, So that trees improve the nutrient content of organic, Regulating plant vegetative and reproductive growth of the relationship between, Reach effective control longan chongshao and improve the quality of flowers. The best period is before the young leaves did not show to take measures of control longan chong shao, At this time, Adopt 180 times yuhualing spray on the surface, Can effectively control chongshao, Flowering rate of up to 95.72%, Flower purity rate reaches 95.72%, The female flower rate reaches 45.21%. If processing is not prompt, When a flowered ear of young leaf already started to launch,Then must coordinate use with yuhualing and ethrel.
