摘    要:我国当季化肥利用率较低,不仅浪费人力、物力、财力,而且有害于生态环境。影响化肥利用率的因素较多,除使用不当外,还有化肥养分释放不符合作物需肥规律,如养分释放过快使作物来不及吸收而损失等。为此,各国致力于开发缓释/控释肥料。国外开发的缓释/控释肥料由于成本高,只能用于非大田作物。我国根据国情,致力于开发低成本可用于大田作物的缓释/控释肥料,目前已有不少科研院校取得了可喜的成绩,建议结合水稻施肥技术开展推广示范工作。

关 键 词:缓释肥料  控释肥料  大田作物

Abstract:China's fertilizer efficiency is quite low in the same season, leading to a vast waste of labor power, material and financial resources, even harming the ecological environment. There are many factors affecting the fertilizer efficiency, beside the improper application, the different nutrient release from the crop's demand, eg., a loss resulting from the fast release of nutrients but the slow absorption. For this reason, the development of slow controlled release fertilizers are devoted. As the high cost of the products from abroad, they cannot be applied in field crops. Some researches on slow/controlled release fertilizers with low cost for field crops have been advanced in institutes and universities in China. The product should been recommended to the rice application.
Keywords:slow release fertilizer  controlled release fertilizer  field crop
