- 摘要:
- 为了研究日光温室生物菌肥的效应,采用二次正交旋转回归设计方法,研究了3种生物菌肥的4种施肥方案对草莓果实糖酸含量的影响。结果表明:4种施肥方案对草莓果实糖酸含量均有影响;浓度适合时,不同的施肥方案交互使用具有相互促进的作用,而浓度较高时,交互使用会产生拮抗作用。该研究以施肥方案为决策变量,以草莓果实糖酸比为目标函数,建立草莓果实糖酸比与其参数因子间的数学模型:Y=7.90183-0.08025X1-0.05442X2-0.01692X3+0.02417X4-0.13173X12+0.20977X22-0.14660X32-0.00910X42+0.25987X1X2+0.06475X1X3+0.05562X1X4-0.02500X2X3-0.01587X2X4+0.03850X3X4;同时确定了提高草莓果实糖酸含量的最佳施肥方案为,EM菌肥液体喷施197275~202725g/L、绿康微菌肥液体喷施1941~2059g/L、A50液体菌肥喷施071975~078025g/L、A50菌肥粉末土壤施用14395~15605kg/667m2。
- Abstract:
- In order to study the effect of biofertilizer on strawberry,the effect of different biofertilizer on strawberry sugar acid content was discussed by using quadratic orthogonal rotational regression design.The results showed that,four different biofertilizer all had effect on strawberry sugar acid content.Suitable for concentration,different fertilization scheme which was used alternately had function of mutual promotion,while at high concentration,interaction using antagonistic effect was produced.In this study fertilization scheme as the decision variables,strawberry fruit sugar acid ratio as the objective function,a strawberry fruit sugar acid ratio and the mathematical model were established between parameters factors Y=7.90183-0.08025X1-0.05442X2-0.01692X3+0.02417X4-0.13173X12+0.20977X22-0.14660X32-0.00910X42+0.25987X1X2+0.06475X1X3+0.05562X1X4-0.02500X2X3-0.01587X2X4+0.03850X3X4.From the result,and concluded the best fertilization schedule was as follows,EM liquid spraying was 1.97275~2.02725 g/L,Lyukangwei liquid spraying was 1.94100~2.05900 g/L,A50 liquid spraying was 0.71975~0.78025 g/L,A50 powder application was 143950~156050kg/667m2.
