Screening of Cultivation Techniques and Model Construction of Good Quality and Proper Yield on Tobacco Variety PVH1452
摘要
Abstract
[Purpose] The aim was to screen for the cultivation techniques of good quality and proper yield on PVH1452.[Method] The effect of nitrogen rate,plant spacing,remained leaves,topping stage and their interactions on yield and output value were analyzed through L27 (313) orthogonal test.[Results] Nitrogen rate,(plant spacing x remained leaves) and (nitrogen rate × plant spacing) had significant effect on yield of PVH1452 varieties,(spacing x remained leaves) and nitrogen rate had significant effect on output value,topping stage on the yield and output value were not significant impact,then yield and value contained 56.8％ and 45.7％ of the dependent variable changes;the highest com bined yield of PVH1452 was nitrogen 6.5 kg,spacing 0.55 m,remained 18 leaves;the highest output value combination was nitrogen 6.5 kg,remained 18 leaves;screened optimum yield model Y=179.804 + 16.406X1 + 15.9X2X3-13.961X1X3,the optimal output value model for the Y =3 569.956 +452.367X2X3 + 441.883X1.[Conclusion] The residuals of the two models were in accordance with the normal distribution,which can provide the theoretical basis for the selection of PVH1452 cultivation techniques.关键词
