The invention relates to a Wheat Ecological special-purpose fertilizer and an application method thereof, belonging to the technical field of fertilizer. The wheat ecological fertilizer including basic tiller fertilizer and panicle fertilizer application, the method comprises the following steps: seeding and tillering stage, per mu of wheat field 1~3 times fertilizer of tillering 45~55 kg; panicle differentiation period, wheat panicle fertilizer per mu 15~25 kg. The invention of the wheat ecological fertilizer based on the growth characteristics of wheat and fertilizer demand characteristic design, by adjusting the number of elements in the ratio of NPK, the growth of wheat added trace elements, specific anti nitrification inhibitors and other chemicals, to meet the wheat in the whole growth period of the main nutrient elements and trace elements of demand, by enhancing the efficiency improve fertilizer use efficiency increase. The application method of the invention is designed according to two peak periods of fertilizer requirement in the growth of wheat, and the application method is scientific and reasonable, so as to facilitate the absorption of wheat and reduce the application cost.

技术介绍
传统肥料使用中存在着严重的盲目性和浪费问题。肥料的施用往往以农民的经验为主,这也是导致我国肥料利用率偏低的原因之一。我国肥料利用率N肥为35%,P肥为15%,K肥为40%,远低于发达国家。除了肥料利用率低下外,普通肥料还存在着过量施用的问题。过量施化肥在农田系统中的损失会引起水体富营养化和大气温室效应。因此,如何有效地提高肥料利用率,加大化肥的技术含量,研制高效、无污染的作物生长专用肥料已成为现代农业科学研究的重大课题。小麦生长专用肥是根据小麦的生理需要而配制的,将氮磷钾和中微量元素等营养元素进行科学配比制成的颗粒肥料。它具有有机无机结合、长效速效结合、常量元素和微量元素结合的特点,达到高产、优质、增效的多元作用效果。在小麦生育中有两个需肥高峰期,分蘖期和孕穗期。小麦若要高产,生长前期应个体生长旺盛、根系发达、分蘖快、叶色浓绿,群体较大,奠定好高产苗架;生长中期,要求麦秆粗健有力,群体生长整齐,叶色青绿;抽穗后,穗头整齐,灌浆快,籽粒饱满,叶片适时落黄,青杆黄熟 ...
