江淮丘陵地区水稻颖壳不闭合现象造成水稻减产,通过田间试验,研究科学施用含有多种中微量元素的有机无机复混肥对防治水稻颖壳不闭合现象的效果。结果表明,与普通复合肥常规施肥方法的处理相比,通过科学施用有机无机复混肥使水稻颖壳不闭合发生率降低26.9～39.4百分点,并在促进水稻有效分蘖、穗粒数方面具有显著效果,水稻增产率为43.8%～66.6%,但在促进株高与穗长方面效果不明显。 Rice yield was reduced due to glume closure in Jianghuai hilly region. The effects of applying organic-inorganic complex fertilizers containing various trace elements and trace elements on the non-closure of rice glume were studied through field experiments. The results showed that compared with the conventional fertilizer application, the incidence of non-closure of rice glume decreased by 26.9-39.4 percentage points through scientific application of organic-inorganic compound fertilizers, which was significant in promoting efficient tillers and grains per spike The yield of rice increased from 43.8% to 66.6%, but the effect on plant height and spike length was not obvious.
