摘要
采用 311—B二次回归最优设计 ,以Zn、B、Fe肥为供试因子 ,配以N、P、K等大量元素肥料作基肥 ,番茄径粗为目标函数 ,对番茄茎粗数学模型进行了研究 .根据模型得出最佳施肥量为 :硼酸 0g/m2 ,硫酸锌 0 0 7g/m2 ,硫酸亚铁 0 14g/m2 .并对锌、硼。
Tomatoes stalk size maths model were studied using twice Fuzzy-design with 311-B,multi-factors with Zn,B,Fe,adding N,P,K as basic fertility.The result is that the suitable fertility quantities;boric acid is 0 g/m 2 zinc sulfate is 0 07 g/m 2,ferrisulphasis is 0 14 g/m 2,The single factors effective and mutual function of Zn,B,Fe were analysed.
