稀土多元水稻分蘖肥的施用效果

Effects of Rare Earth and Multi-Element Compound Fertilizer in Tillering Stage in Rice

[目的]研究稀土多元水稻分蘖肥在水稻促返青、促分蘖方面的应用效果。[方法]在水稻返青期,按不同比例追施稀土多元水稻分蘖肥,收获后对产量、农艺性状进行比较分析。[结果]与追施尿素相比,追施稀土多元水稻分蘖肥180 kg/hm2、追施复合肥分别增产12.5%、3.1%。[结论]与追施尿素和复合肥相比,追施稀土多元水稻分蘖肥可不同程度提高水稻经济产量。

[Objective]The research aimed to investigate the effects of rare earth and multi-element compound fertilizer on regreening and tillering.[Method] Rare earth and multi-element compound fertilizer were applied in different degree in green returned stage,and grain yield and agricultural traits were investigated and analyzed in harvest stage.[Result]Compared with applying urea,the grain yield of applying rare earth and multi-element compound fertilizer 180 kg/hm2 and applying compound fertilizer in tillering stage increased 12.5% and 3.4%.[Conclusion] Compared with applying urea and compound fertilizer,applying rare earth and multi-element compound fertilizer could increase grain yield in different degree.
