摘要
利用１５Ｎ同位素研究了水稻基穗型施肥法的效果。结果表明，在等量氮肥条件下，基穗型施肥法能够提高水稻有效穗数、颖花数、结实率和籽粒重量，是降低水稻生产成本，提高水稻产量的有效措施。
The effect of basal ear fertilizer application on uptake and utilization of fertilizer and soil N by rice was studied with 15 N tracer technique. The results showed that the basal ear fertilizer application is an effective approach to increase numbers of effective ears,caryopsis, spikelets, seed setting percentage, seed weight and yield of rice and reduce the cost of rice production under the condition of applying equal doses of nitrogenous fertilizer. \ \
