人们一直在探讨着作物与它的环境诸因素之间的关系,其中特别研究着肥料用量和作物产量之间的关系,因为它对于合理施肥,发展与农业相适应的化肥工业,以及一定条件下作物产量的估计等,都有其重要的参考意义。特别是肥料与产量之间定量关系的确定,对于应用电子计算机运算最佳施肥方案提供一种参数,更有其价值。所以肥料与产量之间定量关系的研究一直受到各国农学家和农业化学家的重视。
The relationship between crop and its environmental factors has been explored, with particular attention being given to the relationship between fertilizer use and crop yield because of its relevance to the rational application of fertilizers, to the development of fertilizers compatible with agriculture, and to certain conditions Estimated crop yield, etc., have their important reference value. In particular, the determination of the quantitative relationship between fertilizer and yield provides more value for the application of the best fertilization solution for computer calculations. Therefore, the quantitative relationship between fertilizer and yield has always been the focus of agronomists and agricultural chemists in various countries.
