摘要
通过田间试验,研究在插秧施肥一体机条件下,不同施肥方式对水稻产量和效益的影响。结果表明,采用新型农机插秧施肥一体机,减少了化肥投入和施肥次数处理,极大地提高了化肥利用率,且不影响水稻产量。其中,采用插秧施肥一体机施用高浓度复合肥,在减氮22.5%同时免施分蘖肥的情况下,水稻效益最好。
Through field experiments, the effects of different fertilization methods on Rice Yield and benefit were studied under the condition of transplanting and fertilization machine. The results show that the new agricultural machinery transplanting and fertilizing machine can reduce the input of compound fertilizer and times of fertilizing, and greatly improve the utilization rate of fertilizer, do not affect the yield of rice. Among them, the rice benefit is the best when applying high concentration compound fertilizer with transplanting and fertilizing machine at 22.5% nitrogen reduction and no tillering fertilizer application.
