Effects of New Multi-Element Chelated Fertilizer on Yield Increase of Winter Wheat
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%.
