Abstract

This study aimed to determine the energy use and greenhouse gas emissions in pecan production. Energy use efficiency indicators and greenhouse gas emission rates were calculated for the 2022–2023 production season. The energy input and output for pecan production were calculated to be 21,548.08 MJ ha⁻¹ and 73,812.43 MJ ha⁻¹, respectively. The energy use efficiency was found to be 3.43, with a specific energy of 5.07 MJ kg⁻¹, an energy productivity of 0.20 kg MJ⁻¹, and a net energy value of 52,264.35 MJ ha⁻¹. The direct energy required is 8209.46 MJ ha⁻¹ (38.10%), indirect energy is 13,338.61 MJ ha⁻¹ (61.90%), renewable energy is 290.95 MJ ha⁻¹ (1.35%) and non-renewable energy is 21,257.13 MJ ha⁻¹ (98.65%). The total greenhouse gas emissions were calculated to be 1356.05 kgCO_2‑eq ha⁻¹ and the greenhouse gas emission rate was 0.20 kgCO_2‑eq kg⁻¹.

确定土耳其山核桃（Carya illinoiensis）生产的能源利用效率和温室气体（GHG）排放量

本研究旨在确定山核桃生产中的能源使用和温室气体排放情况。计算了 2022-2023 年生产季节的能源利用效率指标和温室气体排放率。经计算，山核桃生产的能源输入和输出分别为 21,548.08 兆焦耳/公顷-1 和 73,812.43 兆焦耳/公顷-1。能源利用效率为 3.43，比能量为 5.07 MJ kg-1，能源生产率为 0.20 kg MJ-1，净能源价值为 52,264.35 MJ ha-1。所需直接能源为 8209.46 兆焦耳/公顷-1（38.10%），间接能源为 13338.61 兆焦耳/公顷-1（61.90%），可再生能源为 290.95 兆焦耳/公顷-1（1.35%），不可再生能源为 21257.13 兆焦耳/公顷-1（98.65%）。经计算，温室气体排放总量为 1356.05 kgCO2-eq ha-1，温室气体排放率为 0.20 kgCO2-eq kg-1。
