The cultivation and management technology of cherry radish
Cherry radish is a small radish, which is round in fleshy root, 2 to 3 cm in diameter, white in flesh, red in root bark, 15 to 20 g in single root weight, 20 to 25 cm in plant height, and short growing period, usually 30 About days, with a strong adaptability. Not only is it fresh and delicious, but it also has a high nutritional value. It can be eaten raw, fried, pickled, and served as a side dish, and is well received by consumers. In particular, some large hotels and restaurants have become more popular and have become delicacies on the table. Especially when it comes to listing in winter and spring, it is even more attractive. At present, the most widely cultivated varieties are the 20-day large root and the 40-day large root introduced from Japan. First, the cultivation season Cherry radish can be cultivated in open field, but also can be protected in plastic greenhouses, greenhouses and other cultivation. The open cultivation can be carried out in spring and autumn. The spring season is generally sown in mid-March to early May, and autumn is generally planted in early August and late September. Spring and autumn. The protected cultivation period in winter is from early October to early March in the following year. Second, soil preparation and basal-fermented cherry radishes have strong adaptability to the soil, but it is best to use sandy loam with loose and fertile soil, good drainage, and water and fertilizer retention. Land preparation requires deep plowing, soil drying, leveling, fine hoeing, and even mixing of fertilizer and soil. Cherry radish has a short growth period, and has a smaller fleshy root. Therefore, the requirements for the type and quantity of fertilizers are not very strict. Therefore, it is generally not necessary to top-dress the radish, and basal fertilizer should be the main ingredient. Generally, about 4000 kg of fully-fertilized manure is applied per mu, and 5-8 kg of superphosphate is applied as a seed fertilizer. The cultivation method is generally used in Xiao Ping, which is 1 meter wide and easy to manage. Third, sowing cherry radish generally use drill method. The spacing is about 3 cm, and the spacing is about 10 cm. The amount of seed is 100 g. It is not appropriate to plant too dense, because too dense will lead to lack of light, petiole lengthened, pale leaves, weak growth, the lower leaves yellow off, fleshy root is not easy to expand. Seeds can be pre-soaked with germination or live. The soaking and germination is soaked in warm water of 30°C for 4 to 5 hours. After being removed, it is wrapped in gauze and placed on the environment of 20°C to germinate. When the young root breaks through the seed coat, it can be sowed. In the live broadcast, the seeds must be sprinkled, covered with soil, and filled with water. Fourth, field management Cherry radish field management is relatively simple. When the cotyledons are unfolded, the first time the seedlings are planted, leaving the seedlings with normal and well-growth seedlings, and the rest are gone. When the true leaves grow to 3 to 4 pieces, they are seeded. During the growth of cherry radish, we must especially keep the soil in the field moist, not too dry or too wet, and the watering should be balanced. The soil moisture content should be 70% to 80% of the field water capacity. If the soil moisture is insufficient, not only the fleshy root is thin, but also the fibrous roots increase, rough skin, spicy, hollow and other undesirable traits, affecting its yield and quality. Too much water or dry and damp, can easily cause cracking of the fleshy root. If the seedlings grow poorly and there are symptoms of fertilizer deficiency, a small amount of available nitrogen fertilizer should be applied along with the water. As the cherry radish plants are smaller, we should timely carry out cultivating and weeding to eliminate the competition for weeds on the nutrient of cherry radish, keep loose topsoil, increase the aeration of topsoil, and promote the absorption of nutrients by the root system. Especially in the autumn, when the seedlings are in high temperature and rainy season, weeds thrive, and we should strengthen weeding and weeding. Cherry radish has strong cold resistance but is not heat resistant. When the ambient temperature exceeds 25°C, poor growth is exhibited, and the plants are prone to diseases and insect pests, mainly including viral diseases and aphids. Attention should be paid to timely prevention and control. Fifth, the harvest period of the cherry radish is generally about 30 days, when the meat root is beautiful and bright, the diameter can reach 2 cm when harvested. Different cultivation seasons and cultivation methods have different specific harvesting times, so timely harvesting should be done. If it is harvested too early, it will affect the production. If it is too late, it will lead to an increase in fiber, and it will easily produce crooked hearts, cracked roots, etc., affecting its quality and commercial value.
