【摘要】 在八五八农场进行水稻硼肥小区量级试验,采取叶面喷施硼酸钠,探索水稻硼肥施用量。试验结果显示,施用硼肥对水稻抽穗期和成熟期有一定的促进作用,且施硼肥量在3水平即用量为337.5 g/hm2时,水稻成熟期最早。施用硼肥对提高水稻产量也有很大作用,从产量及方差分析结果显示,施用硼肥不同量级之间产量差异显著,施用硼肥处理产量都高于不施硼肥的B0处理,随着施用硼肥量级增加产量也相应增加。B3处理施用硼肥量3水平,即施速乐硼337.5 g/hm~2,三次重复产量都最高。因此,在该试验地肥力基础上,2水平的硼肥推荐施肥量过低,3水平的硼肥推荐施肥量更适宜。更多还原

【Abstract】 Anstract: The level test of Rice boron fertilizer was made in 858 farm which used sodium borate spraying on leaf surface to research the application amount of boron fertilizer. The result indicated that boron fertilizer play an important role in promoting the heading and the ripening, when the amount of boron fertilizer was 337.5 g/hm~2, the ripening stage was the earliest. The results of yield and variance analysis indicated that boron fertilizer had a great effect on increasing yield, The yield had significant difference among orders of boron fertilizer, the treatment of using boron fertilizer were higher than treatment-B0, the yield increased with the increasing of boron fertilizer, the amount of treatment-B3 which was spraying solubor 337.5 g/hm~2 can achieve the highest yield. So the suitable amount of fertilizer under the soil fertility was treatment 3.更多还原
