摘要
本文依据A级绿色稻米的施肥要求,探讨在有机氮和无机氮1∶1的条件下,氮素肥料施用的比例对基肥、分蘖肥、穗肥、粒肥利用率和生产力的影响,为A级绿色稻米的施肥体系提供了科学依据。
To study the effects of nitrogen fertilizer application rate on the productivity of class A green rice and utilization of fertilizers with the rate of organic nitrogen and inorganic nitrogen were 1：1, an experiment of different nitrogen fertilizer application rate was carried out in different periods. The results showed that improving nitrogen fertilizer application rate in tiller stage can increase the utilization and absorption of N-fertilizer.
