摘要
以中稻品种天优3301为材料,设置施用氮肥4种不同的基肥、蘖肥、穗肥比例处理,研究其对中稻产量的影响。结果表明,基肥、蘖肥、穗肥不同施用比例对中稻天优3301产量影响较大。在施纯N 11 kg/667m2中等肥力条件下,最优施用方式是基肥∶蘖肥∶穗肥比例为2.5∶4.5∶3。
The effects of 4 different nitrogen application ratios among basal, tillering and panicle fertilizers on grain yield of a mid-season rice variety Tianyou 3301 were studied. The results showed that different nitrogen application ratios among basal, tillering and panicle fertilizers had great effects on grain yield of Tianyou 3301. Under medium soil fertility and applying nitrogen of 11kg/667m^2, the optimal method of application is basal, tillering, panicle fertilizer ratio of 2.5∶4.5∶3.
