Cherry radish is a small radish, a root vegetable. The variety has the advantages of wide adaptability, delicate quality, rapid growth, beautiful color appearance, good taste, no pesticide pollution, etc. At present, it has become a new type of vegetable that is easy to cultivate and benefits quickly.
I. Variety selection At present, there are mainly Japanese roots on the 20th and root on the 40th. The two cherry radishes are round in fleshy roots, 2-3 cm in diameter, 15-20 g in weight, red in root bark, white in flesh, 20-25 cm in plant height, adaptable, and not heat-resistant. Suitable for open and protected cultivation in spring and autumn. The main difference between the two is that the former has a warm temperature and climate, and the growth period is shorter, 20-25 days; the latter has stronger cold resistance and a longer growth period of 35-40 days.
Second, planting cherry radish must be cultivated in a suitable soil, fleshy roots can grow more fat and stronger, the shape is correct, appearance smooth, beautiful color, good quality. Therefore, the land should be selected from sandy loam fields where there is sufficient sunlight, irrigation and irrigation conditions are good and the soil is loose. Before the site preparation, 500-750 kilograms of excreta or 450-550 kilograms of chickens and ducks were excreted. If there is plant ash and cake, the effect is better. Then deep plowing, squeezing, squeezing, flattening, width 1.2 meters, sorghum 20 centimeters, ditch width 30 centimeters, parallel drill, row spacing 10 cm x 4 cm. Before planting, first open the sowing ditch, the ditch depth is 1.5 cm, and the seeding amount per 1-mu is 1-1.5 kg. After the seeds are sown, they shall be filled with fine soil and no pressure shall be applied. Watering to the soil will be beneficial to emergence. Because the cherry radish plants are short and have a short growing period, they can also be used for intercropping with melon crops.
The spring and autumn cultivation can be sown in stages from mid-March to early May, early August to late October. In winter cultivation, when the temperature is lower than 15°C, it can be covered with a plastic film to promote its growth.
Third, field management
1. Miaomiao: When the temperature reaches 20-25°C after sowing, it will emerge in about 2-3 days. When the cotyledons unfold to reveal the first true leaf, the first time the seedlings should be carried out and the weak or dense seedlings can be removed. When the second true leaf grows out in a few days, the second thinning is carried out, and then the dense seedlings are removed. When the plant grows to 3-4 true leaves, the seedlings will be planted at a distance of 4 cm.
2. Water and Fertilizer Management: Cherry radish should maintain proper moisture in the soil during growth. Water should be uniform and the field should be kept moist. However, dryness is not too wet. The soil moisture content should be 70%-80%. The fibrous roots of the fibrous roots increase, resulting in rough, spicy, hollow and other phenomena. Due to the short growing period, basically no additional dressing is required during the growth period. If the plants appear to be too short or the leaves are yellow in color, some quick-acting nitrogen fertilizers can be used, and the fast-harvesting 5000 times solution plus 0.3% potassium dihydrogen phosphate solution can be sprayed. 2-3 times, the effect of increasing production is significant.
3. Weeding and weeding: During the growth of cherry radishes, we must carry out cultivating and weeding in time, especially cherry radishes cultivated in the autumn. Because the climate is hot and rainy, the weeds thrive, and it is easy to submerge the cherry radish plants themselves, so every 6-10 days we must cultivate the weeds. Once, it also helps to keep the soil loose and prevent top soil compaction, facilitating the growth and enlargement of cherry radish roots.
4. Pest control: Japanese cherry radish under the conditions of high temperature and drought climate, plant growth and weakness, prone to cabbage caterpillar, aphids, etc., can be used DuPont hit 3500 times or Wan Ling 2000 times liquid spray control.
Fourth, harvest cherry radish generally grow 25-35 days after harvest, a few need about 40 days. At the time of harvesting, the whole plant can be pulled up gently, and the fleshy root surface is bright and beautiful. The root ball is even and smooth, with a diameter of 2-3 cm. The upper leaves are like small spinach leaves, dark green or light green. However, harvest time is different in different cultivation seasons, and timely harvesting is required. If the temperature is high in the fall, it can be harvested 3-5 days in advance. Harvest time should not be too early or too late, if too early will affect the yield; too late fiber increases, easy to produce cracks, hollow, affecting product quality.
