Suitable for sowing greenhouse cultivation, generally sowing in late January to mid-February and harvesting in early April; mulching cultivation in open field, sowing in late March to early April, late May to early June Harvested.
Seeding method 1 to 2 seeds per hole, sowing rate per acre 100 to 200 grams. After sowing, cover 0.5 cm with fine soil, then cover the film to keep moist and promote seed germination.
The selection of good breeds is the selection of varieties with short growing period, strong cold resistance, strict vernalization requirements, late bolting, and not easily hollow. For example, choose spring radish varieties such as "White Jade Spring", "Spring White Jade", "Spring Radish 9646" and so on.
Land preparation is done by selecting sandy soil or sandy land, planting 2 to 3 times deep before sowing, and plowing at a depth of not less than 20 cm, and turning to pick up field stones and residual agricultural film. When the last time the land was turned, Mushi rotted 3,000 kg of organic fertilizer and 30 kg of compound fertilizer.
Field management can generally be planted 4 to 5 days after sowing, and the seedlings must be broken and seeded in time after seedling emergence; the seedlings should be seeded and seedlings must be checked in the first 10 days; 2 to 3 true leaf seedlings should be planted in time;
The optimum growth temperature of spring radish is above 12Â°C, and the temperature is too low to be easily vernalized by low temperature. The pre-growth period is mainly based on insulation, and the temperature in the shed is appropriately increased to promote the growth of rosette leaves. When encountering strong cold air, it must be covered with cold-proof materials.
Spring radish is generally not short of water, should pay attention to timely drainage, only in the trench when the soil whitish water properly, especially the root swelling period, the need for increased water, pay attention to soil moisture, timely irrigation. Drip irrigation is best when irrigation.
Pest control pests are aphids, cabbage caterpillars, which can be controlled by insecticides such as imidacloprid, insecticides, and chlorhexidine. Diseases mainly include downy mildew and black rot, and agricultural measures such as field crop rotation and enhanced ventilation can be used for prevention.
When timely harvested in the radish meat roots above the root diameter of 5 to 6 cm or more, according to market conditions, harvested in batches supply market.
