For those who have harvested tender shoots many times, they should be fertilized in time after each harvest in order to supplement a large amount of nutrients lost as a result of harvest. Urea is generally the main topdressing. The main pests of cold vegetables in winter are ground tiger, Spodoptera litura and aphids, which can be controlled by poison bait or trichlorfon spray, while the diseases are mainly anthracnose, root rot, etc., anthrax can be controlled by chlorothalonil, root rot can be controlled by carbendazim.
