通过室温变化对贝尔曼漏斗法分离松材线虫Bursaphelenchs xylophilus效果影响的分析,认为室温是影响线虫分离量的主要因素,二者呈正相关关系,以平均室温与线虫分离量的相关性最好,其回归方程式为Y=-19.49+29.51X。 Based on the analysis of the effect of Bursaphelenchs xylophilus on the separation of Bursaphelenchs xylophilus by Berman funnel at room temperature, room temperature is considered as the main factor influencing the isolation of nematodes. The correlation between them is positive, and the correlation between average room temperature and nematode isolation is the best. The regression equation is Y = -19.49 + 29.51X.
