摘  要:
为实现化肥使用量零增长,八步区逐年控制主要农作物化肥使用量,发展绿肥种植,推广秸杆还田技术,增施有机肥,普及测土配方施肥技术,开展集成推广化肥减量增效技术,八步区2018年7月-12月进行了水稻秸杆还田化肥减量增效试验研究。结果表明:水稻秸杆还田,能提高产量,再结合减少化肥使用量,水稻产量最高,效益最好。处理3在植株性状表现、产量、效益等方面均表现最好,因此初步推荐处理3的化肥用量为八步区水稻生产化肥的最使佳用量。

摘  要:
In order to implement the fertiliser use zero growth, and eight steps area control main crop fertilizer usage year by year, the development of green manure planting, promoting straw counters-field set technology, increasing organic fertilizer, popularizing soil testing and fertilizer technology to carry out the integration promote fertilizer efficiency reducing technology, eight steps zone in July 2018-December the rice straw counters-field fertilizer efficiency reducing test research. The results showed that rice straw returning to field could increase the yield and reduce the use of chemical fertilizer. Treatment 3 showed the best performance in plant traits, yield and benefits, so it was preliminarily recommended that the fertilizer amount of treatment 3 was the best fertilizer amount for rice production in the eight-step zone.
