应用低频电流处理种子,是近年试用的一项新技术。去年旅大地区在玉米、小麦、水稻、高粱、大豆、谷子等作物上进行广泛试验,普遍表现出苗早、根粗、根长、提早成熟,多数地块增产。根据复县50个点的试验结果,用
Application of low-frequency current treatment of seeds, is a new technology trial in recent years. Last year, a large number of experiments were carried out on crops such as corn, wheat, rice, sorghum, soybean and millet in the Luda area. Early emergence of seedlings, root thickening, root length, early maturity and production increase were observed in most plots. According to 50 points of complex county test results, with
