根据有关单位对小麦植株进行化学分析的结果,每收获一百斤小麦籽实,需要吸收氮素三斤左右,磷酸一点五斤左右,氧化钾二至四斤。因此,合理施肥是夺取小麦高产,降低生产成本的重要措施。现将常用各种有机肥料和化学肥料三要素含量摘录如后,以供参考。在使用这个材料时,请注意考虑下面几个因素。一、每收获一百斤小麦籽实所吸收的氮、磷酸和氧化钾的数量是随着气候、土壤
According to the results of the chemical analysis of wheat plants by the relevant units, about one kilogram of wheat seeds per kilogram of wheat seed needs to be absorbed, about 1.5 kilograms of phosphoric acid and about two to four kilograms of potassium oxide. Therefore, rational fertilization is an important measure to seize high yield wheat and reduce production costs. Now commonly used in a variety of organic fertilizers and chemical fertilizers after extracting three elements such as for reference. When using this material, please consider the following factors. First, each harvest of a pound of wheat seeds absorbed by the number of nitrogen, phosphoric acid and potassium oxide is with the climate, soil
