根据有关文献介绍,施入等量营养物质的复合肥料与单纯肥料对改善冬、春麦籽粒品质和增加产量有相同的效果。在一系列的谷类作物试验中,用硝铵磷钾和碳铵磷钾的效果比单纯肥料好。很多研究者认为,这是因为复合肥施入土壤时,营养元素的分配比较均匀,容易为作物根系吸收,同时,复合肥中水溶性磷的含 According to the relevant literature, the application of compound fertilizer with the same amount of nutrients and simple fertilizer have the same effect on improving grain quality and yield of winter and spring wheat. In a series of cereal crop trials, the benefits of ammonium, ammonium and potassium phosphates were better than those of simple fertilizers. Many researchers believe that this is because when the compound fertilizer is applied to the soil, the distribution of nutrient elements is relatively uniform and it is easy to absorb the root system of the crop. Meanwhile, the content of water-soluble phosphorus in the compound fertilizer
