Session Five Agricultural Technology Measures Agricultural technical measures are the basic measures to prevent soil erosion, improve the soil and ensure agricultural production. It can in situ infiltration of rainwater to prevent surface runoff caused by soil erosion, soil structure can be improved and enhance soil water absorption capacity for crop growth to create good conditions. First, Zuo Zuo and Tian Ping He Ping Zuo Zuo Zuo Zuo Zuo Tian has a long history in the Taonan region. After years of continuous improvement and improvement, it has been widely promoted. In general, cultivated crops are mostly used in this way. According to Tianshui, Suide, Xifeng, Dingxi, elm
