当前农业发展要求高产、高效、优质,还要求持续发展。对农作物进行合理施肥、调配营养、平衡营养已十分重要。施肥能提高作物产量、改善品质,早为世界农业工作者共认。经多年统计全世界粮食增产肥料的作用约占40％～60％。 现在我国农田因缺乏大量营养元素而影响产量和品质的已很少见。但微量营养元素供给不足,造成缺乏或潜在缺乏而形成的产量低品质差的田块则时有发生。因此我国各地微量营养元素肥料产、销量大增即在解决 The current agricultural development requires high yield, high efficiency and high quality, and also requires sustainable development. The rational fertilization of crops, the deployment of nutrition, nutrition balance has been very important. Fertilization can improve crop yields, improve quality, as early as the world’s agricultural workers recognize. After years of statistics, the role of the world’s grain yield fertilizer accounts for about 40% to 60%. Nowadays, it is rare for farmland in our country to affect yield and quality due to the lack of large amount of nutrients. But the lack of micronutrient supply, resulting in lack of or potential lack of production of low-yielding poor plots are from time to time. Therefore, trace fertilizers throughout China, production and sales increase is to be resolved
