1. Spring radish: early spring seeding, early summer harvests, early spring radish seeding takes place between february and april, with a long-term average of 25 to 60 days. Large areas to the north of the yangtze are more widely cultivated and planted in the cities of central and downstream shanghai, nanjing, jiangsu province, and wuhan, hubei province, in february-march, with harvests in early april-june. In march-april, planting took place in the hwang huai sea area, where harvests took place between early may and june. High latitudes, high altitude areas such as north-east, north-west and north-west china were seeded in 4 to 5 months, with harvests in june and july. 2. Shalob: the seeding took place between may and june and could be harvested from july to august. It takes time and sunlight to sow white carrots in the summer, and it is easier to mature and have enough sugar. 3 autumn radishs: the northern regions are mainly seeded between mid-july and early august, followed by harvests in late october and mid-november, while the colder north-east or north-west regions are seeded in mid-july, followed by harvests in early october, higher latitudes, lower temperatures and longer periods of planting. 4. Trolls: the planting period for the radish is generally suitable for the first half of september. Late seeding results in low yield and low yield due to low temperatures. The planting of radish requires the provision of more lax and humid soil conditions, where seeds are spread evenly and soil moisture is maintained, and the seedlings can grow after a half-month wait. Water should be watered in such a way that insufficient water supply affects the roots of the carrots, thereby affecting their productivity and quality of growth, and can easily cause problems of hollowness or indeterminateness, so water should be watered in such a way that local humidity and control of the moisture are taken into account。
