本刊讯在吉林省图们市凉水镇,水稻秧苗两两成组,整齐地排列在田间。和传统的种植方式不同,这些水稻行与行之间的距离有宽有窄。这正是中科院东北地理所在当地大力推行的“高光效种植模式”。这种看似简单的栽种技术却能够有效提高粮食产量,被不少农业专家直呼为“耕作革命”。高光效种植模式就是将田地的垄向调整至磁场南偏西18~20度,以达到最佳光照。同时,采取宽窄行组合垄种植法,可以提高垄间透光率。
Benxi hearing in Tumen City, Jilin Province, Liangshui Town, rice seedlings in pairs into groups, neatly arranged in the field. Different from traditional planting methods, the distance between these rice rows and rows is wide and narrow. This is exactly what the northeast geography of the Chinese Academy of Sciences vigorously promotes. “High-efficiency planting model”. This seemingly simple planting technique can effectively improve the grain yield and is called by many agricultural experts as “farming revolution”. High light efficiency planting mode is to adjust the field ridge to the magnetic field south west 18 ~ 20 degrees, in order to achieve the best light. At the same time, the combination of width and width row ridge planting method, can improve the transmittance of the ridge.
