Choosing the suitable soil to grow radish should be selected as the former crop with less consumption of fertilizer, more organic matter left, and no diseases and pests of the same species. The cruciferous vegetables need to be avoided as a forehead, otherwise it is easy to cause diseases. Radishes have a wide adaptability to sandy soil. In order to obtain high-yield and high-quality products, it is still better to use deep, loose, well-drained and relatively fertile sandy loam soils. When cultivated in a suitable soil, the growth of fleshy roots can be fully expanded. The shape is correct, the skin is clean, and the color is beautiful. The plots require deep plowing and uniform fertilization to promote the increase of effective nutrients and beneficial microorganisms in the soil, and to loosen the air permeability, which is conducive to the absorption of nutrients and moisture by the roots, thus rapidly expanding the leaf area and accelerating the expansion of the fleshy roots. 75 kg of compound fertilizer can be applied as base fertilizer per acre. Then carry out soil disinfection and control of underground pests. The bactericide is selected from 50% carbendazim 600 times solution or 70% thiophanate-methyl 800-1000 times solution spray, and the insecticide can be sprayed with 48% Lester's EC 800 to 1000 times solution. The quality of radish seeds sown has great influence on the growth and yield of radish plants. In order to make the seedlings neat, seedling-full and seedling-strong, seeds should be carefully selected, and only full, sound seeds should be used to eliminate pods, crushed, and mildewed seeds. The seeding rate depends on the seed quality, soil quality, climate, and seeding method. Autumn radish mostly uses on-demand or drill. The seed amount is determined according to the density of the seedlings, and the on-demand seedlings are 25-30 cm apart. Each nest is seeded with 4-5 seeds, and the seeds are opened in the nest so as to avoid crowding after emergence and affect the seedling quality. The management of the field should be promptly followed by the rapid growth after the seedlings are unearthed, and the seedlings must be planted in time to prevent crowding, shading and causing leggy. To set the seedlings early, split between the seedlings, timely seedlings to ensure Miao Qi and Miao Zhuang. Intermittent seedlings are usually 2 to 3 times in size, with the exception of the seedlings whose weak, deformed, and pest-infested species are removed. Reasonable watering and watering are mainly determined according to the growth characteristics of the radish, the requirements of the water for each growth period, and the climatic conditions and soil conditions. After sowing, if the weather is dry, immediately pour water once, and then pour water once when the seedlings begin to emerge, keep the ground moist, ensure that the seedlings are neat, and reduce the occurrence of viral diseases. If it is rainy, it must be drained in time to prevent death. The scientific cultivating autumn radish is a large and medium-sized radish variety with a long growing period. Based on the application of basal fertilizer before sowing, topdressing should be applied appropriately, especially for plots with low soil fertility and insufficient basal fertilizer. Applying fertilizer can significantly increase yield. Nitrogen fertilization should be used to water or fertilize water. After the radish “breaks bellyâ€, it enters the rose stage, which is the rosette stage. To promote the expansion of the leaf area, it is also appropriate to apply a quick-acting nitrogen fertilizer. When the roots of the meat root are inflated, the compound fertilizer is topdressed. Helps fleshy root enlargement. During the first 20 days before harvest, once a week, spraying 0.2% potassium dihydrogen phosphate two times for foliar dressing has a good effect on improving yield and quality of fleshy roots. Scientifically cultivating and controlling weeds and radishes require many times of cultivating loose soil in the growing period of radish, especially in the seedling period, the temperature is relatively higher, rain is more, weeds grow rapidly, and weeding and weeding. In high ridge cultivation, the soil on the ridge is easily washed by rain, and the cultivator needs to be combined with soil. Long-shaped radish of the exposed species, because the neck is slender and weak, often easy to bend, lodging, the initial stage of growth needs to be bred to expand the root. Prevent lodging so as to form curved radishes later. At the end of the rosette, the leaves were already ridged and the cultivator was stopped. Weeding was done only by hand. The pests of radish are mainly maggots and soft rot. Each mu uses 12% of agricultural streptomycin sulfate WP 10 million units of water plus 50-75 kg of water or 57.6% of chlorothalonil dry granules 1000-1200 times of spray, while Combined irrigation roots. Control aphids, imidacloprid can be sprayed with water. The timely harvest of autumn radish depends on the variety and time to market. The harvest has a low yield and the plate has no taste; the harvested meat root is frozen or hollow, and the quality deteriorates, causing a hollow. When the root diameter expanded to 8 to 10 cm, length 25-30 cm when the harvest is more appropriate.
