1. Thinning: The thinning of radish begins when it grows to 4-5 leaves, and the seedlings of radish grow rapidly after being unearthed. The number and time of thinning depends on the climate, the degree of pest damage, and the amount of seeding. The time of thinning should be based on the principle of "morning thinning, sparsely remaining seedlings, and late setting of seedlings".
2. Reasonable watering: The principle of "watering less and watering frequently" should be mastered. During the period before the seedlings break white, the seedlings should be squatted with small water to inhibit the growth of lateral roots and make the taproots penetrate deep into the soil. From broken white to bare shoulders, more water is needed, proper irrigation is required, but not too much water, to prevent the leaves from growing too much, "do not dry the ground without watering, water only when the ground turns white".
3. Top dressing method: the liquid fertilizer can be applied in the early stage, which can be applied on the foliage, and the medium top dressing can be applied in the hole or furrow. The amount of top dressing should master the principle of "light, heavy and light". Top dressing is applied when two true leaves of seedlings emerge. This is the first thinning of large and medium varieties of radish. The soil can be lightly loosened after thinning, and then thin human feces and urine are applied. Between the lines, the spread of the full cast.
4. Intertillage weeding, soil cultivation, and removal of yellow leaves: Intertillage weeding and soil cultivation must be timely, especially when the radish seedlings sown in autumn are small, the climate is hot and rainy and weeds are prone to occur.
