摘要
为了摸清优质中稻鄂中5号的适宜氮肥施用量和最佳施用方法,开展氮肥施用量和施肥方法的试验。结果表明,鄂中5号最高产量(6055.5kg/hm2)施氮量为225kg/hm2,氮肥的施用方法以基肥60%,分蘖肥30%(分两次追施,第一次在返青后追20%,7d后再追10%),10%作穗肥的分配方法为宜。
In order to study on optimal nitrogen fertilizer amount and application method of top quality middle-season rice variety ＂E-zHONG No.5＂, a field experiment of four nitrogen fertilizer amounts and two application method was carried out in Nanhu experimental station, Hubei Academy of Agricultural Sciences. The results showed that application amount of nitrogen fertilizer was 225kg N / hm2 when the yield in E-ZHONG No. 5 reached the maximum. The optimal application method of nitrogen fertilizer was 60% basal fertilizer, 30% tillering fertilizer （two times of application, 20% application of fertilizer after transplanting rice seedlings 7 days, 10% application of fertilizer after transplanting rice seedlings 14 days）, 10% heading fertilizer. The maximum yield in E-zHONG No. 5 was 6 055.5 kg / hm2.
