本文研究了甘草盖度和地上鲜重与地下干重的关系,产量与盖度的关系可用方程Y=aX~b来拟合,与地上鲜重的关系可用方程Y=a+bX来拟合.通过盖度与地上鲜重的综合分析,建立了产量预测方程:Y=97.669+2.915X_1+0.004X_2~2.
The relationship between licorice coverage and aboveground fresh weight and underground dry weight was studied in this paper. The relationship between yield and cover can be fitted by the equation Y = aX ~ b, and the relation with aboveground fresh weight can be fitted by the equation Y = a + bX Through the comprehensive analysis of coverage and fresh weight, the yield prediction equation was established: Y = 97.669 + 2.915X_1 + 0.004X_2 ~ 2.
