中甘11号结球甘蓝高产喷肥模式化初探

Preliminary Study on Moderlization of Foliage Spray for High-yield of "Zhong Gan No. 11

依据系统工程理论的原理和方法，研究了Ｓｒ、Ｂ、Ｚｎ、Ｍｏ、Ｃｕ五种微显元素对中甘１１号结球甘蓝产量、品质的影响及各因子间的复合效应。试验结果表明，各因子对中甘１１号产量的作用是：Ｓｒ＞Ｂ＞Ｚｎ＞Ｃｕ＞Ｍｏ。获得了中甘１１号亩产在６０００ｋｇ以上的优化组合方案是：Ｓｒ０．０５４％～０．０６１％，Ｂ０．０３５％～０．０４２％，Ｚｎ０．０４７％～０．０５７％，Ｍｏ０．０３２％～０．０３８％，Ｃｕ０．０５０％～０．０５６％，为微量元素在蔬菜上的应用提供了科学依据．

Experiments were conducted to study the effect of five trace elements on 'Zhong Gan No. 11' output by the theory and way of system engineering. The compound effects of various factors were also investigated in this paper. Our result suggest that the effect of various factors on 'Zhong Gan No. 11' yield are Sr>B>Zn>Cu>Mo. The optinum seeking methods by which'Zhong Gan No.11' output is more than 6000 kg/mu is obtained as follow: Sr: 0. 054%￣0. 061 % B: 0. 035%￣0. 042% Zn: 0. 047 %￣0. 057 % Mo: 0. 0325%￣0. 038% Cu: 0. 050% ￣0.056% The results obtained is this research gives scientific base for the application of trace elements on vegetable prod notion.
