小粒黄豆高产栽培数学模型的研究

MATHEMATICAL MODEL OF YIELD FOR SMALL GRAIN SOYBEAN

摘要:

小粒黄豆亩产仅100kg 左右,产量低而不稳,严重影响外贸出口和经济效益。采用三元二次回归正交旋转设计进行田间试验,建立产量函数模型和经济收益模型。模型解析表明:磷酸二铵与2、3、5—三碘苯甲酸的主因素效应和交互效应显著.亩种植1.7万株,施磷酸二铵5.5—7kg,2、3、5—三碘苯甲酸3g 左右,小粒黄豆亩产115—145kg,亩收益110—145元。三因素最高水平的组合措施,亩产可达150kg,亩收益150元。

Abstract:

The yield of small grain soybean (Glycine max (L. ) merr) is only 100kg/mu, low and unstable, which greatly influenced its export and economical value. The field experiment was conducted using the orthogonal rotation design of quadratic regression with three factors and the models for yield and economical benefit have been developed. Analysis of models showed that main effects of ammonism phosphate (18—46—0)and TIBA and interaction between them were significant. Yield of 115—145kg and benefit of 110—145 yuan per mu were achieved from the treatment in which density of 17000 plants, 5. 5—7kg of ammonium phosphate and 3g of TIB A permu were used. Yield of 150Kg and benefit of 150 yuan per mu can be obtained with the best combination of three factors according to the model.
