- W2389503133 abstract "Experiment was conducted to evaluate the effects of balanced fertilization on yield and benefit of maize in the black soil of Songnen Plain.The results showed that balanced fertilization had a significant positive effect to maize yield and benefit of Shuangcheng and Hailun and Yi'an.Limiting factor on yield of maize in the black soil of Heilongjiang province was N P K.Compared with optimum treatment,the maize yield and profit of no nitrogen fertilization treatment were decreased by 23.4% and 2 514 yuan·hm-2;no phosphate fertilization treatment by 15.9% and 1 699 yuan·hm-2;no potassium fertilization treatment by 16.3% and 1 646 yuan·hm-2;no fertilization treatment by 35.5% and 2 762 yuan·hm-2;farmer fertilization treatment by 4.9% and 458 yuan·hm-2.The yield and benefit of optimum treatment was better than any other treatments,it means that the design of optimum treatment was reasonable.Nitrogen,phosphate and potassium agronomic efficiency of Shuangcheng was 23.9,48.2and 31.5 kg·kg-1 and Hailun was 11.4,16.9and 21.7 kg·kg-1and Yi'an was 13.1,29.6and 13.1 kg·kg-1,respectively.Considering nutrient's balance and fertilizer utilization,the amount of phosphate and phosphate fertilizer should be improved on the basis of the amount of nitrogen fertilizer,which would make the optimum treatment more reasonable to reach maize high-yield,high-quality and efficiency." @default.
