| Abstract: |
| The litchi and longan orchards in main producing areas have been over 25 years old and the canopy
closure phenomenon is serious，which result in lower yield and low quality of fruit，increase of production costs，decline
of farmers’ income. So it’s time to adopt thinning technology to reform the orchards. The small-scale farmers tend to
choose random manner which need thinning cut，but the large-scale farms tend to use the standardized thinning way.
The thinning technology have been applied widely in main producing areas，such as Maoming，Zhanjiang，Qinzhou after
China litchi and longan researh system was established. Choosing a litchi demonstration located in Gaozhou and a longan
orcard located in Maoming as typical cases，the results showed that the input costs decreased and total yield，output
value increased year by year after the implementation of thinning technology. |
