摘要
为探讨中稻超级稻需肥规律,在灵川县潭下镇老街村委老街自然屯进行中稻超级稻测土配方施肥"3414"肥效试验。结果表明,不同施肥量对超级稻产量影响明显;最佳施肥量为氮198.15kg/hm2、磷96.25kg/hm2、钾187.5kg/hm2,最佳产量为8 035.65kg/hm2。
In order to explore the fertilizer requirement rule of middle-rice and super-rice, a ＂3414＂ fertilizer effect experiment was conducted in Laojie natural village, Tanxia township, Lingchuan County. The results show that different fertilization amounts have obvious impact on super-rice＇s yield and the best fertilization amounts are N198.15kg/hm2, P96.25kg/hm2 and K187.5kg/hm2, and highest yield＇s fertilization amounts are 8035.65kg/hm2.
