增施化肥是水稻增产的重要措施。虽然,在不同地域其肥力状况有所差异,施肥方法不尽相同,但特点基本趋以一致。水稻早育稀植的“看天、看地、看苗”施肥方法,具有因地因天因苗制宜综合管理施肥的特点。在目前尚未全面开展测土施肥技术前提下,运用掌握好传统的“三看”施肥方法,对提高化肥利用率,增加产量,仍具有一定指导作用。
Fertilizer application is an important measure to increase yield of rice. Although the fertility status varies in different regions, the methods of fertilization are not the same, but the characteristics tend to be the same. Rice early education sparse planted “to see the sky, see, see Miao” fertilization methods, because of the reason due to seedling system should be integrated management of fertilization characteristics. Under the premise of not fully carrying out the soil testing and fertilization technology, using the traditional “three-look” fertilization method can still play a guiding role in improving fertilizer utilization rate and increasing output.
