Technical and Economic Evaluation Report on Overcoming the"Alternating Bearing"of Mid-late Maturing Varieties of Litchi
This article constructed an evaluation index system from three aspects:economic benefits,ecological benefits and social benefits,to conduct economic evaluation on key technologies to overcome the"alternating bearing"of mid-late maturing varieties of litchi.The results showed that the average yield per hectare of the demonstration orchard in 2020,2021 and 2022 were 7965.00 kg/hm2,11550.00 kg/hm2 and 9330.00 kg/hm2,respectively,and the average fluctuation range of the annual average yield per hectare was 25.13％,which was in line with the target value of average yield per hectare above 7500 kg/hm2 and annual average yield per hectare fluctuation range within 30％in the Industrial Technical Plan for Overcoming the"Alternating Bearing"of Mid-late Maturing Varieties of Litchi,and could bring high economic,ecological,and social benefits to the local area.It was suitable for large-scale promotion in mid-late maturing litchi planting areas throughout the Guangdong province.
