枯萎病病株的级别(x)与单株皮棉产量损失百分率(y)之间的关系,可用下列回归式表示:y=-1.1+24.74x 枯萎病田间群体病指(x)与皮棉产量损失百分率(y)之间的关系,可用下列回归式表示:y=-5.3851+0.9062x 病株相邻的健株有明显的补偿作用,病级越高补偿越明显。
The relationship between the level of fusarium wilt (x) and the percentage of lint yield per plant (y) can be expressed by the following regression formula: y = -1.1 + 24.74x Fusarium Wilt Disease (x) and lint yield loss The relationship between the percentage (y) can be expressed by the following regression formula: y = -5.3851 + 0.9062x strains adjacent strains have obvious compensatory role, the higher the level of compensation the more obvious.
