Cultivation techniques of cherry radish in autumn

Cherry radish plant height 2025cm, fleshy root round, diameter 2cm 3cm, root skin red, flesh white, single root weight 1520g, delicate, fresh and delicious, its edible method can be eaten raw, fried, drowned and side dishes, deeply welcomed by consumers. At present, it has become a new kind of vegetable with easy cultivation and quick profit.

1. Soil preparation and fertilization

Cherry radish has strong adaptability to soil, but the sandy loam with loose and fertile, good drainage, water and fertilizer conservation is the best. Soil preparation requires deep ploughing, soil drying, leveling, fine raking and fertile soil mixing evenly. It is generally cultivated in a small flat bed with a width of 1 meter. Because the growth period is short and the fleshy root is small, the requirements for the type and quantity of fertilizer are not too strict, so it should be based on sufficient base fertilizer, and generally there is no need to apply topdressing. 2500kg fully mature barnyard manure was applied as base fertilizer per mu, and 5-8kg superphosphate was used as seed fertilizer.

Second, sowing seeds

Autumn open field cultivation can sow seeds one after another from mid-September to early October, harvest by stages, generally strip sowing, plant spacing 3cm, row spacing 10cm, sowing depth about 1.5cm, seed consumption per mu 100g. It can soak seeds to accelerate germination and sow seeds, or it can be direct seeded. The varieties used are red jazz, Dutch red star cherry, Japanese cherry radish and so on.

III. Field management

Cherry radish is too dense and lack of light, which will lead to longer petiole, light leaf color, yellowing and shedding of the lower leaves, and the fleshy root is not easy to expand. When the cotyledons are unfolded, the seedlings are carried out for l times, leaving the seedlings with normal cotyledons, and the rest are removed, at the same time, seedlings are carried out in areas where the seedlings are relatively dense. The seedlings are fixed when there are 3 or 4 true leaves.

Special attention should be paid to keeping the soil moist, watering should be balanced, and the soil water content should be 70% to 80% of the field capacity. If the seedlings grow poorly and have symptoms of fertilizer deficiency, a small amount of available nitrogen fertilizer can be applied with water.

The cherry radish plant is small, so it is necessary to plough and weed in time, eliminate the competition of weeds for nutrients, and promote the absorption of nutrients by radish roots.

IV. Disease prevention and pest control

Cherry radish has strong cold resistance, but not heat resistance. When the ambient temperature exceeds 25 ℃, the growth is poor, and diseases and insect pests are easy to occur, mainly virus diseases and aphids, so attention should be paid to prevention and control.

V. timely harvest

Cherry radish generally grows for 25-30 days, the fleshy root is beautiful and bright, and can be harvested one after another when the diameter reaches 2 cm, which affects the yield prematurely, and the late increase of fiber is easy to produce split root and bran heart.
