Radish is a semi-hardy vegetable. Generally, winter radish is mainly planted. Sowing in late August to late September, the growth period is 70- 120 days, and harvesting in late June to February of the following year.

Radish planting method

1, soil preparation and fertilization

Radish root system is developed, so it is necessary to choose plots with deep soil layer and fertile and loose soil and plow ahead of time. The big radish should be ploughed more than 33 cm, and the general radish should be ploughed about 24 cm. Radish grows well and needs more fertilizer, and the base fertilizer should be applied adequately. Before soil preparation, 2000 kilograms of decomposed human excrement and urine and manure mixed fertilizer should be applied to each mu, and the bottom fertilizer should be applied to the hole and fully mixed with the soil. Generally, deep ditch and narrow box cultivation are adopted to facilitate drainage. The height of the border is 15-20cm, and the width is about 140cm. Plant 3-4 rows per box.

Step 2 sow seeds

Radishes are broadcast directly, and the amount of seeds used per mu is 400-500 grams. The planting density of large radish growing on the ground is generally 40X40, and the planting density of medium and small radish is 30-33cm. Plant a big radish in each pit and cover it with soil for 2 cm after sowing.

Time and method of radish planting

3, thinning seedlings

Radish seedlings grow rapidly after being unearthed, so they should be interplanted in time, otherwise they will be crowded and shade each other, resulting in white growth of plants. The first thinning is performed when the first real leaf is unfolded, and the second thinning is performed when 2-3 real leaves are unfolded. Seedling (7-9 real leaves) when the belly is broken. The method of fixing seedlings is to choose a strong seedling with the characteristics of planting varieties and pull out all the others.

4. Water and fertilizer management

When the fleshy roots grow and develop, if the water is insufficient, the fleshy roots of radish will become smaller, rougher, lignified and spicy. If there is too much water, it is easy to grow in vain. There is less water demand at seedling stage, so less watering is needed. Water less before your stomach breaks to promote direct rooting.

Radish fertilization should be based on base fertilizer. Radish with short growth period has sufficient basal fertilizer, so it can be chased less. The growth period of radish is long, so topdressing should be increased appropriately. After the first and second thinning, dilute human excrement and urine should be chased once each. You can apply feces for the third time when your stomach is broken, and the feces can be thicker. At the same time, apply 5 kg of phosphate fertilizer and 5 kg of potassium sulfate per mu. When the radish is exposed to the shoulder, apply decomposed human manure 1000- 1500 kg per mu, and apply plant ash 100- 150 kg per mu during the vigorous growth period of fleshy roots.

5, intertillage weeding and ridging

The growth of radish needs loose soil and good air permeability. Radish sown in autumn is easy to grow, so it needs intertillage and weeding, and intertillage and border tillage should be combined. Varieties that have been exposed for a long time are often prone to bending and lodging, so we should pay attention to cultivating the soil to make radish grow upright.
