Method for planting selenium-enriched pears

The invention relates to a method for planting selenium-enriched pears. According to the method, cockroaches serve as a medium for enriched element selenium and are safer than traditional foliar fertilizers, and the problem of selenium poisoning caused by uncleanness in cleaning is solved. Compared with other soil fertilizers, the selenium enrichment by the cockroaches is by converting element selenium into a mode that is more favorable for absorption by plants, and enriched selenium has lower toxicity than inorganic selenium and does not diffuse easily.
