The application discloses a droplet microfluidic sorting method, a sorting system, an electronic device and a storage medium. The droplet microfluidic sorting method comprises the following steps: acquiring a first time point of positive droplet trigger sorting in a microfluidic device; determining a second time point of the positive droplet reaching an outlet of a collection channel according to the first time point and a time length of the positive droplet passing through the collection channel to reach the outlet of the collection channel; the outlet of the collection channel is used for forming an oil droplet; and comparing an oil droplet formation time point closest to the first time point with the second time point to determine a target oil droplet containing the positive droplet.
