| 摘 要： | 以南方双季稻田改种春玉米杂交晚稻这一新型水旱轮作制为研究对象，研究了稻田春玉米不同施肥水平、不同追肥次数及不同追肥时间的效果，结果表明：稻田春玉米最佳施氮量为３００ｋｇ／ｈｍ＾２左右，以二次肥（即基肥和穗肥各占一半）较为省工。穗肥以９－１０叶全展时施用增产效果较好。

| Abstract: | Countering the new water-dry rotation system that double croping of rice is changed by spring maize and hybrid late rice The researchers made experiments of different applying nitrogen fertilizer amount,different applying nitrogen fertilizer number of times and suitable time.The results showed that the best applying nitrogen fertilizer amount is 300kg/hm 2,It is simpler applying two time fertilizer (amount of foundation fertilizer is as much as fertilizer for head sprouting).Suitable time of applying fertilizer for head sprouting is during the 9th-10th leaver from the low. |
