Skillful cultivation of high quality white radish

When planting radish, we should choose crops with less fertilizer consumption, more residual organic matter and no same diseases and insect pests as the previous crop. It is necessary to avoid cruciferous vegetables as the first crop, otherwise it is easy to lead to diseases. Radish has a wide adaptability to sandy soil. in order to obtain high-yield and high-quality products, it is better to use sandy soil with deep soil layer, loose soil, good drainage and fertile sandy soil. Only when cultivated in suitable soil, the fleshy root can be fully expanded, the shape is correct, the skin is smooth, and the color is beautiful.

? The land requires deep ploughing.

Flat, uniform fertilization, so as to promote the increase of available nutrients and beneficial microorganisms in the soil, and can be loosened and ventilated, which is conducive to the absorption of nutrients and water by the absorbing roots, so that the leaf area expands rapidly and the fleshy roots expand rapidly. 75 kg ternary compound fertilizer can be applied per mu as base fertilizer. Then carry on the soil disinfection and sterilization and the control of underground pests. Sowing seeds

The quality of radish seeds has a great influence on the growth and yield of radish plants. In order to make the seedlings neat, complete and strong, seeds should be carefully selected and only full and sound seeds should be used to eliminate shriveled, broken and moldy seeds. The sowing rate should be determined according to the seeds, and the autumn radish is mostly sown on demand or by strip. The seed quantity is determined according to the sparse density of the seedlings, the distance between the seed nests is 2530 cm, each litter is 4 seeds, and the seeds are scattered in the nest to avoid crowding after emergence and affect the quality of the seedlings.

? Field management

Seedlings grow rapidly after being unearthed, and time should be given to seedlings to prevent crowding, shading and overgrowth. It is necessary to set the seedlings early, divide the seedlings into different stages, and set the seedlings at the right time to ensure that the seedlings are smooth and strong. Generally, the seedlings were divided into two or three times, and the seedlings were removed from the seedlings which were weak, deformed, and harmed by diseases and insect pests. Rational watering

Watering is mainly determined according to the growth characteristics of radish, water requirements in each growth period, climatic conditions and soil conditions. After sowing, if the weather is dry, water should be watered immediately, and water should be watered again when the seedlings begin to emerge, so as to keep the ground moist, ensure neat emergence, and reduce the occurrence of virus diseases. If it is rainy, it should be drained in time to prevent dead seedlings.

Scientific topdressing

Winter radish is a large and medium-sized radish variety with a long growth period. On the basis of applying sufficient base fertilizer before sowing, topdressing should be applied properly, especially for the plots with low soil fertility and insufficient base fertilizer, topdressing can obviously increase the yield. Fertilizer should be applied with nitrogen fertilizer to water or dung water. After the radish "broken belly", entered the peak leaf growth stage, that is, the rosette stage, in order to promote the expansion of leaf area, it is also appropriate to apply a quick-acting nitrogen fertilizer; in the peak stage of fleshy root expansion, a compound fertilizer is applied, which is helpful to the expansion of fleshy root. On the other hand, spraying 0.2% potassium dihydrogen phosphate twice a week for foliar topdressing 20 days before harvest had a good effect on improving yield and fleshy root quality.
