摘要
采用盆栽试验方法,研究了氮肥追施时期与施用方法对小麦产量的影响,结果表明:拔节期叶面喷施氮肥能够明显提高小麦的株高、穗长、穗数、穗粒数和千粒重,从而获得高产。
The pot experiment was adopted to study the effects of topdressing stage and application methods of nitrogen on wheat yield. The resuhs showed that spraying nitrogen at jointing stage could achieved maximum yield clue to significantly increasing the plant height of wheat, spike length, spike number, grains per spike and 1 000-grain weight.
