摘要
试验结果表明,棉田施用"控释"嘉安磷复合肥后,在每公顷减少825 kg化肥施用量,节省纯N252 kg、P2O5 36 kg、K2O 126 kg,节约成本1 050元的情况下,每公顷增产子棉584.3 kg,增加收益3 388.90元,投入产出比提高3.35。
The result of this experiment indicated that the application of controlled-release composite fertilizer in cotton field increased yield of seed cotton by 584.3 kg.hm-E,output by 3 388.9 Yuan RMB per hectare, ratio of input and output by 3.35, decreased the application of N 252kg·hm^-2,P2O536kg·hm^-2,K2O126 kg·hm^-2,sared the cost by 1 050 Yuan RMB per hectare.
