摘要
从经济效益、生态效益、社会效益三个方面构建评价指标体系,对克服荔枝中晚熟品种"大小年"关键技术进行评价.结果表明,2020年、2021年、2022年使用该技术示范果园的单位面积产量分别为7965.00kg/hm2、11550.00kg/hm2、9330.00kg/hm2,且年际单位面积产量波动幅度均值为25.13％,符合《克服荔枝中晚熟品种"大小年"产业技术方案》中平均单位面积产量7500kg/hm2以上、年际单位面积产量波动幅度在30％以内的目标值,且能够给当地带来较高的经济效益、生态效益和社会效益,适合在广东省中晚熟荔枝种植区大面积推广.
Abstract
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.
