Cherry radish is a small radish with a rounded fleshy root, 2 to 3 cm in diameter, white in flesh, red in root bark, 15 to 20 g in single root , 20 to 25 cm in height , and short in growth period, generally 30 Around day, it has strong adaptability. Not only the quality is tender, fresh and delicious, but also has a high nutritional value. It can be eaten, fried, pickled and served as a side dish, which is very popular among consumers. In particular, some large hotels and restaurants are more popular and have become a delicious dish on the table. Especially in the winter and spring season, it is particularly attractive. At present, the more extensive cultivars are the 20-day root and the 40-day root introduced from Japan.
First, the cultivation season cherry radish can be cultivated in open field, or in plastic greenhouses, greenhouses and other protected areas. Open field cultivation can be carried out in spring and autumn. Spring sowing is generally in succession in mid-March to early May, usually sown in succession in early August to late September fall. Spring and autumn. The winter cultivation period is from early October to early March of the following year .
Second, the soil preparation and application of the base cherry radish have strong adaptability to the soil, but the sandy loam with the soil loose and fertile, well drained, water and fertilizer is the best. When cultivating the land, it is required to deep-plow, dry soil, smooth, fine, and evenly mixed with fertilizer. Cherry radish has a short growth period and a small fleshy root. The type and quantity of fertilizer are not very strict. Therefore, it is generally not necessary to apply fertilizer, and it should be based on base fertilizer. Generally , about 4000 kilograms of fully decomposed manure is applied per acre , and 5 to 8 kilograms of superphosphate is applied as a seed fertilizer. The cultivation method is generally small flat, and the width is 1 meter, which is convenient for management.
Third, sowing cherry radish is generally carried out by means of strip. The plant spacing is about 3 cm, the row spacing is about 10 cm, and the seed amount is 100 g. It should not be planted too densely. Because it is too dense, it will lead to insufficient light, the petiole will become longer, the leaves will be light, and the growth will be weak. The lower leaves will yellow and fall off, and the fleshy roots will not be easily inflated. Seeds can be pre-soaked for germination or live. Soak the seeds and germination for 4 to 5 hours with warm water at 30 °C. Wrap them in gauze and remove them in a 20 °C environment. When the roots break through the seed coat, they can be sown. When broadcasting live, you need to first ditch the seeds, cover the soil and then practise the soil, and then fill the water.
Fourth, the field management of cherry radish field management is relatively simple. When the cotyledons are unfolded, the first seedling is carried out, leaving the seedlings with normal cotyledons and strong growth, and the rest are gone. When the true leaves grow to 3 to 4 tablets, the seedlings are fixed. During the growth of cherry radish, the soil in the field should be kept moist. It should not be too dry or too wet. The watering should be balanced. The soil water content should be 70% to 80% of the water holding capacity of the field . If the soil moisture is insufficient, not only the fleshy roots are small, but also the undesirable traits such as increased roots, rough skin, spicy taste, and hollowness may affect the yield and quality. Excessive moisture or sudden dryness and wetness may cause cracking of fleshy roots. If the seedlings are poor in growth and have symptoms of lack of fertilizer, a small amount of quick-acting nitrogen fertilizer should be applied with the water. Because the cherry radish plants are small, it is necessary to timely cultivate and weed, eliminate the weeds to compete for the nutrients of the cherry radish, keep the topsoil loose, increase the aeration of the topsoil, and promote the absorption of nutrients by the roots. Especially in autumn cultivation, the seedlings are in the hot and rainy season, the weeds grow vigorously, and the cultivating and weeding should be strengthened. Cherry radish has strong cold resistance but is not heat resistant. When the ambient temperature exceeds 25 °C, it shows poor growth, and the plant is prone to pests and diseases, mainly virus diseases and mites, and attention should be paid to timely prevention and treatment.
Fifth, the growth period of harvesting cherry radish is generally about 30 days. When the fleshy root is beautiful and bright, the diameter can reach 2 cm. Different cultivation seasons and cultivation methods have different specific harvest time, so timely harvest is needed. If the harvest is too early, it will affect the yield. If it is too late, it will lead to an increase in fiber, and it will easily cause sputum, cracking, etc., affecting its quality and commercial value.
