“肥料是植物的粮食。”随着我国化肥制造工业的迅速发展,施用化肥水平逐年提高,但是怎样科学地施用化学肥料,以充分发挥肥料增产作用是值得注意的一个重要问题。近年来,随着“农业学大寨”运动的深入开展,群众科学用肥的经验有新的提高,各地三结合科学实验组织,开展了合理施用化肥科学实验,取得了一些进展。 “Fertilizer is the grain of plants.” With the rapid development of China’s fertilizer manufacturing industry, the level of chemical fertilizers applied has been increasing year by year. However, it is worth noting that how to apply chemical fertilizers scientifically in order to give full play to fertilizer production increases is an important issue to be noticed. In recent years, with the deepening movement of “learning from agriculture in Dazhai”, the masses have made new progress in the experience of using chemical fertilizers. Various scientific experiments have been organized in all places to carry out rational experiments in fertilizer science and some progress has been made.
