摘要
通过田间试验和土壤植株分析，建立数学模型，筛选相关性大的回归方程，总结出棕壤土花生氮磷钾养分丰缺指标、花生“定产”公式、土壤养分换算系数、化肥当季利用率、单位产量荚果氮磷钾吸收量等花生平衡施肥参数。
Some balance parameters of applying fertilizer were summarized through experiments, i.e., abundance index of N, P, or K in peanut, equation for determing peanut yield, conversion coefficient of soil nutrients, utilization ratio of fertilizers in current season and N, P and K absorption of per unit yield. Therefore, these parameters could provide scientific basis for balance of applying fertilizer for peanut in brown soil.
