1 前言“烤烟测土微机推荐施肥研究”历时六年,经历布点小试、广收参数、建立数学模型和田间验证示范两个阶段。本文为朱家堡验证示范阶段的技术总结。本项技术与目前国内外常用的由产量和施肥量试验数据回归拟合得到的函数关系、计算推荐施肥量的方法截然不同,也不同于
1 Preface “Flue-cured soil computer recommended fertilization research” lasted six years, experienced distribution of small test, widely received parameters, the establishment of mathematical models and field demonstration demonstration two stages. This article is Zhu Jiabao verification demonstration phase of the technical summary. This technique and the current domestic and foreign commonly used by the yield and fertilizer test data regression fit the function of the relationship between the calculated recommended amount of fertilizer is very different from the method is also different from
