提高氮肥肥效,为国内外的一个重要研究课题,从各种途径进行研究。如改进施肥技术、合理分配施用、深施肥、球肥、硝化抑制剂、v 字施肥法、改进施肥机具等,国内近年在碳铵的研究上,卓有成效。针对内蒙古地区当前大面积春小麦产量还不高、化肥用量还不多、很多地块灌溉还不及时以及春小麦生育期短、降雨少等的实际情况,我们设想着重从播种沟内施用氮肥这一途径进行研究,以提高化肥肥效。播种时在小麦播种沟内条施有机肥料及磷肥、国内外均有研究报导,也已在生产上应用。但对氮肥的研究资料则比较少,近年的研究报导,有的认为氮肥不宜在播种沟内
Improve the efficiency of nitrogen fertilizer, for an important research topic at home and abroad, from a variety of ways to study. Such as improving fertilization technology, rational distribution of application, deep fertilization, ball fertilizer, nitrification inhibitor, v word fertilization method, improve fertilization equipment, domestic research in recent years, ammonium bicarbonate, fruitful. In view of the fact that the current large-area spring wheat production in Inner Mongolia is still not high, the use of chemical fertilizers is not too large, lots of plots are not irrigated in time, and the growth period of spring wheat is short and the rainfall is low, we envisage the emphasis on the application of nitrogen fertilizer from the sowing ditch Research to improve fertilizer efficiency. When sowing in the trench sowing of organic fertilizer and phosphate fertilizer in wheat, both at home and abroad have research reports, has also been applied in production. However, the research on nitrogen fertilizer is relatively small, in recent years, research reports, and some think nitrogen fertilizer should not be seeding ditch
