During the root enlargement period, appropriate potassium fertilizer should be applied. After emergence, the seedlings should be given as appropriate before setting seedlings. When the seedlings grow out of 2 true leaves, topdressing with a small amount of fertilizer is carried out. After the second time, the middle seedlings are combined with cultivating and weeding topdressing once. The second round of topdressing was conducted during the radish "break white" to "strapless" period, and the seedlings were then top-dressed. It should be noted that topdressing should not be close to fleshy roots to avoid burning roots. The cultivating and weeding can be combined with irrigation and fertilization. The cultivator should be deep and shallow firstly, first near and far, and stop cultivating after the line is closed.
