据根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。现将麦田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,清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,土壤条件,栽培技术(包括施肥量和施肥方法)品种特性等的不同而发生变化的。如在施肥水平高的情况下,籽粒中的含氮量和茎杆中的含钾量都相应增加。
According to the results of the chemical analysis of the wheat plants by the relevant authorities, each kilogram of harvested wheat seeds needs to absorb around 3 kg of nitrogen, about 1.5 kg of phosphoric acid, and 2 to 4 kg of potassium oxide. Therefore, rational fertilization is an important measure to seize high yield wheat and reduce production costs. Wheat fields are now commonly used in a variety of organic fertilizers and chemical fertilizers content of three elements excerpt such as for reference. When using this material, pay attention to the following factors. I. The quantity of nitrogen, phosphoric acid and potassium oxide absorbed by each pound of harvested wheat seed varies with the variety of climate, soil conditions, cultivation techniques (including the amount of fertilizer and fertilization method), and the like. In the case of high fertilization levels, both the nitrogen content in the grain and the potassium content in the stalk increased accordingly.
