The invention relates to a rice husk and phosphate fertilizer combined application method mitigating apple continuous cropping obstacles; the method comprises the following steps: in apple seedling planting in spring, evenly mixing continuous cropping soil dug from each colonization hole with a fertilizer containing phosphorus elements; adding phosphate fertilizer so as to enable the phosphorus element to equal to 0.05% of the continuous cropping soil (dug from each colonization hole) mass ratio, and evenly mixing said two materials; adding rice husk biology charcoal into the mixture of the continuous cropping soil and phosphate fertilizer, wherein the rice husk biology charcoal equals to 2% of the continuous cropping soil and phosphate fertilizer total mass, and evenly mixing so as to obtain mixed cropping soil; backfilling the mixed cropping soil into colonization holes, and planting seedlings. The method can mitigate damages on seedling roots, can prevent and eliminate harmful fungi in the continuous cropping soil, thus finally mitigating apple continuous cropping obstacles.
