摘要: 通过马铃薯田间“3414”试验结果和土壤氮、磷、钾土测值的分析,建立了氮、磷、钾肥料效应函数、养分丰缺指标、综合效应函数、不同养分丰缺指标下的最佳施肥量以及土壤养分测定值频率分布,从而进行了配方施肥量的确定、配方的计算以及施肥量的建议。
Abstract: Through the potato field "3414" test results and measurements of soil nitrogen, phosphorus and potassium soil analysis, established the nitrogen, phosphorus, potassic fertilizer effect function, abundant nutrient deficiency index, comprehensive effect function, the best fertilizer rate under different nutrient abundance of indicators as well as the determination of soil nutrient value, frequency distribution, thus the determination of formula fertilizer application, the calculation formula and fertilizer recommendations.
