肥料是植物的粮食。经济合理地施用化肥,不仅是提高水稻产量的有效措施,而且是提高化肥肥效,降低农业成本,达到增产增收的好方法。近年来,我县许多社队开展了这方面的科学实验,取得了一定的增产效果。为了能够更好地总结、推广这方面的经验,现将调查所得有关材料整理于后,供参考。 Fertilizer is the food of the plant. Economically and rationally applying chemical fertilizers is not only an effective measure to increase rice yield, but also a good way to increase fertilizer efficiency, reduce agricultural costs and increase production and income. In recent years, many communes and counties in our county have conducted scientific experiments in this area and have achieved some yield-increasing effects. In order to better summarize and popularize the experience in this field, the relevant materials obtained from the investigation are compiled for reference later.
