对三种沙地类型草场飞播蒙古岩黄蓍结实量的测定结果表明,沙地类型决定着蒙古岩黄蓍结实量的高低,相对高度1~3m的平缓沙丘地适宜建立种源基地;蒙古岩黄蓍的结实枝高(X1)与结实量(Y)呈负相关,而结实枝数(X2)、株高(X3)、节数(X4)、侧枝数(X5)和地径(X6)与结实量呈正相关;X2、X6是测定其结实量和选种、育种的主要性状指标,结实直线复回归方程为Y=-2.62+0.04X2+7X6。
The results showed that the type of sandy land determines the fruiting quantity of Ammonium mongolica, and the suitable base for the provenance in the gentle sand dune with a height of 1 ~ 3m. The Mongolian rock The results showed that there was a negative correlation between the height of xylostella (X1) and the yield (Y), while the number of xylosis (X3), number of nodes (X4), number of branches (X5) And X. X6 was the main trait index for measuring the seed yield, seed selection and breeding. The linear regression equation of fruiting was Y = -2.62 + 0.04X2 + 7X6.
