烟草是产质并重的叶用作物,对肥料的反应特别敏感。尤其氮、磷、钾三要素的合理施用量及其适当配比,是保证烟草优质、适产的关键措施之一。本研究根据系统原理和方法,采用旋转通用设计,对氮、磷、钾的施用量及其配比与烤烟产量、品质等性状的关系进行分析,并借助于计算机模拟选优,筛选出最佳方案,为合理施肥提供依据。计算机运算在江西农大计算中心进行。
Tobacco is a yield-based leaf crop that is particularly sensitive to fertilizer reactions. In particular, nitrogen, phosphorus and potassium three elements of the rational application rate and its appropriate ratio is to ensure high quality tobacco, one of the key measures of fitness. According to the principle and method of the system, the universal design of rotation was used to analyze the relationship between the amount of nitrogen, phosphorus and potassium and its proportion and the yield, quality and other traits of flue-cured tobacco, and selected the best by computer simulation Program to provide a basis for rational fertilization.
