新型多元素螯合肥具有活化土壤、提高肥料利用率、改善土壤板结、培肥地力等作用。试验研究了新型多元素螯合肥在冬小麦上的增产效果,结果表明其可以显著提高冬小麦的产量,其中较等养分复合肥增产404.2 kg/hm2,增产率5.1%;较农民习惯施肥增产923.8 kg/hm2,增产率12.4%;较不施肥处理(CK)增产2 433.0 kg/hm2,增产率41.1%。
New multi-element chelated fertilizer has many functions such as activating soil, increasing use efficiency of fertilizer, improving soil hardening, and bettering soil fertility, etc. Experimental study is carried out of yield-increasing effect of new multi-element chelated fertilizers on winter wheat, results show that it can increase yield of winter wheat significantly, compared with same nutrient compound fertilizer, the yield increases by 404.2 kg/hm2, the increasing rate is 5.1%; compared with farmers′ fertilization practice, the yield increases by 923.8 kg/hm2, increasing rate is 12.4%; compared with no fertilizer (CK), the yield increases by 2 433.0 kg/hm2, the increasing rate is 41.1%.
