Radish is semi-hardy, and its growing environment is mild and cool. Seeds can germinate in an environment of 23 degrees, and seedlings can withstand high temperature of 25 degrees. It is not good to sow too early or too late. Generally speaking, it is recommended to be in beginning of autumn one week later. The growth period of radish in autumn and winter is 80 ~ 100 days.

The sowing method can be direct seeding, the row spacing is 50 cm, the plant spacing is 25 cm, the sowing depth is 1.5 cm, and 3-5 seeds are sown in each hole. Combined with soil preparation, 3000 kilograms of decomposed farmyard manure and appropriate amount of chemical fertilizer are applied per mu. The soil preparation must be fine, so that the soil can be thoroughly plowed and raked, and the soil can be empty.

The principle of seedling thinning is early seedling thinning, seedling thinning by stages and seedling fixing later. In production, the seedlings are generally thinned for 2-3 times, and 1 plant is reserved for sowing as needed, and the spacing between seedlings is kept at 10- 13cm.

Radish planting skills:

1, water and fertilizer management: in the early stage, it is necessary to promote the robust growth of leaves and absorption roots and lay a material foundation for the expansion of fleshy roots in the later stage. Small varieties with short growth period, such as sufficient base fertilizer, can be less topdressing. Radish needs different moisture at each stage. For example, during the vigorous growth of fleshy roots, the soil must be kept moist, and it is best not to alternate between dry and wet.

2, intertillage weeding: Autumn radish is in the high temperature and rainy season in the early growth stage, so weeding should be done in time. The intertillage should master the principle of shallow first, then deep and then shallow. The first intertillage after seedling formation should be shallow, and the land can be cut, and the intertillage can be deepened appropriately in the future, but it can't hurt the root system. Radish belongs to the genus Raphanus in Cruciferae and is widely cultivated all over the world. 10 score.
