甘蓝密度与惠满丰最佳组合及其协同效应的研究

采用Ｄ－饱和最优回归设计田间试验测得的参数，建立了以甘蓝产量为目标函数的数学模型。通过数学运算得出，１ｈｍ２底施惠满丰高效活性肥９６０．７ｋｇ、叶喷惠满丰活性液肥３７５０ｍｌ，栽植密度６８５４４株，可望获得最高产量６４１３２ｋｇ，并对单因素效应、互作效应作了剖析。

Study on the Efficiency Relationship between Cabbage Planting Density and Huimanfeng Fertilizer

Based on experimental data,a mathematical model taking cabbage yield as objective function was established by the method of DSaturation firstrate regression design.The result of regression analysis deduced that: when the planting density was 64.13 thousand plants per hectare and 960.7kg base fertilizer of Huimanfeng with the high effect active composing fertilizer was applied and 3 750ml active organic liquid Huimanfeng fertilizer was sprayed on leaves, a high output of 64.13 thousand kg may be attained.In this paper,the single major effect and interactive effcet was also analyzed .
