When cultivating cauliflower in the later stage, intertillage weeding should be carried out, and intertillage weeding should be carried out for 2-3 times without plastic film mulching, and intertillage should be shallow, first far and then near, and root weeds should be pulled out by hand, so as not to damage roots and leaves, and intertillage weeding should be stopped when the ridge is closed.
