通过对西吉县农田能量流的全面分析,揭示出造成农田现状投能水平低和能量效率低的障碍性因素,包括广种薄收的耕作方式,干旱,暴面,雹雨和水土流失。针对障碍性因素,本文提出实行能量集中投入,引进优良品种,加强精耕细作,坡地梯田化和造林种草等措施来提高能量效率。 Through a comprehensive analysis of the farmland energy flow in Xiji County, it reveals the obstacles that cause low energy consumption and low energy efficiency in farmland, including a wide variety of thin harvesting practices, droughts, storms, hail and soil erosion. In view of the obstacles, this paper puts forward some measures to increase energy efficiency, such as concentrating energy input, introducing good varieties, intensifying intensive farming, slope terraformization and afforestation and grass planting.
