本文通过田间试验和土壤养分的测定,提出以空白区产量(基础产量)所需营养为土壤供给,丰产区产量为计划产量。然后应用有关空白区产量与计划产量的相关回归方程,研完了不同作物、不同产量的施肥量,计划产量与基础产量之差所获得的产量为肥料养分供给。按本研究提出的冬小麦、玉米计划产量的施肥量公式计算施肥量,经验证准确性较高。 In this paper, field experiments and determination of soil nutrients were proposed to supply nutrients needed for the production of the blank area (basic yield) to the soil, and the yield of the high yielding area was planned output. Then, applying the regression equation related to the yield of blank area and the planned yield, the yield of fertilizers of different crops and different yields was researched and the difference between planned yield and basic yield was obtained. According to the proposed fertilization formula of winter wheat and corn planted yield, the fertilization amount is calculated, and the accuracy of verification is high.
