摘要
化肥是提高作物产量的物质基础,在过去的几十年中,它在世界农业建设中起过巨大作用。近百年的肥料试验表明,化学肥料具有和有机质一样的持续增产效果,在提高作物产量、品质的同时,还可培肥土壤。随着化肥工业的发展,化肥的负作用会逐渐减小。
Chemical fertilizer is a material basis for enhancing crop yields and has been playing a very important roles in the agricultural production. The fertilizer experiments conducted in nearly one hundred years showed that chemical fertilizers, like the organic matter, have sustainable yieldincreasing effect and can improve the crop quality and soil fertility. With the development of chemical fertilizer industry, their negative effects will gradually become insignificant.
