Analysis of Energy Consumption for Protected Grape Production System in China

Abstract:

This study examines energy consumption of inputs and output used in protected grape production, and aims at to find relationship between energy inputs and yield in the major protected grape producing regions in China. For this purpose, the data were collected from 516 questionnaires which included 304 effective ones by questionnaire survey method. The results indicated that total energy inputs were 57697.84 MJha^-1 where the Chemical with (32.4%) and Fertilizer with about (21.1%) were the major energy consumers. About 53.4% of the total energy inputs used in protected grape production was indirect while 46.6% was direct. The non-renewable shared about 78% whereas the renewable energy did 22%. Average yield and energy consumption are calculated as 25367.22Kgha^-1 and 299333.2MJha^-1. Energy use efficiency, energy productivity, specific energy and net energy were 5.18, 0.44 kgMJ^-1, 2.27 MJkg^-1 and241635.36 MJha^-1, respectively.
