What are the requirements for radish on soil, fertilizer and moisture?

<

Radish is suitable for cultivation in sandy loam, loam, and light viscous loam. In the period of vegetative growth, the absorptivity of radish to nitrogen, phosphorus, and potassium, except for the germination period, was the highest in potassium absorption in all other growth stages, followed by nitrogen and phosphorus. Relatively speaking, the amount of nitrogen, phosphorus, and potassium absorbed was the highest at the peak of pulpy root swelling, and the ratio of absorbed nitrogen, phosphorus, and potassium was 2.0:1.0:2.3. General requirements for the application of basal fertilizer, full use of farmyard manure plus calcium phosphate stacking maturity, 2 kg per 667 m 2 dosage, and application of 35 kg of compound fertilizer, one-time application into the ploughing, requiring deep plowing soil more than 25 cm, playing Broken and flat, so that the soil loose, finely divided evenly. Radish sprouting period, seedling stage water is not much, but the summer and autumn and autumn cultivation, timely watering is not only conducive to emergence and tidy, and can reduce the surface temperature, to avoid high temperature burns sprouts and flu virus disease. The amount of water needed for the early stage of fleshy root enlargement can be properly watered. When most of the leaves of the second leaf ring are exhibited, watering should be properly controlled to prevent the leaves from becoming long. The flourishing root of meat is the period with the largest amount of water, and it should be supplied in time so that the soil moisture content (absolute water content) can be kept at about 20%, which will help improve the yield and quality. If excessive water is supplied and the soil moisture content is high for a long time, poor soil ventilation will increase the lenticels and root scars of the fleshy root, thus affecting the quality of the product. If the soil moisture is insufficient for a long period of time, the roots of the flesh grow slowly, and the meat is thick and spicy. In addition, in the flourishing root of fleshy roots, such as dry and wet soil, it is easy to cause cracking of fleshy roots. Judging from the differences in breeds, the general “exposed type” varieties have poor drought tolerance, and the “stealth type” varieties are more tolerant to drought, but they are less tolerant.
