I. Variety and planting time There are many varieties of radish. According to the season can be divided into autumn radish, spring radish, summer radish and radish four types. The use of idle farms to grow autumn radish is a good variety: Jinan green crisp, heart and other beauty. Early sowing, high temperature during the seedling stage, susceptible to viral disease; late autumn radish sowing, lack of growth period, it is difficult to obtain high yield. Traditional radish planting time is generally appropriate in the middle of August. Second, planting technology 1, soil preparation, fertilization. Idle yards, generally hard texture, after heavy rains, early deep plowing, full sunburn, broken pieces of rubbish, Fuping, Shizu base fertilizer. If the weather is dry, you need to ditch irrigation, the distance between 1 to 1.5 meters, 2 to 3 days, immediately cultivating. The depth is generally 20-25 cm. The roots of radish are more developed. Before ploughing, it is necessary to apply enough basal fertilizer. In general, the quality of Mushi rotizers is 3,000 to 4,000 kilograms, and superphosphate is 15 to 20 kilograms. Do a leveling job, so that the soil is loose, no waste, smooth. Autumn radish is generally planted on ridges, ridge height is 10 to 15 centimeters, spacing is 30 to 40 centimeters, and plant spacing is 15 to 20 centimeters. 2, sowing. Radish sowing is live, when sowing, open a small ditch in the ridge, ditch depth of 4 to 5 cm, after the ditch, a small water poured along the ditch, until the water seepage, the seeds will be evenly spread in the ditch, after sowing Cover 1.5 to 2 cm fine soil. For moisturizing and rainproof, sprinkle a thin layer of wheat straw after sowing, and remove crushed wheat straw the next day or before emergence. Third, field management, 1 seedlings. When the seedlings grow to "pull cross", the first thinning is performed. Combine the seedlings with cultivating and weeding to remove weeds, weak seedlings and diseased seedlings. When 3 to 4 true leaves were grown, the second time the seedlings were planted, and the third time, 5 to 6 true leaves were seeded. 2, watering and fertilizing. Radish seedlings generally do not need watering, after emergence, if the weather is dry, it is necessary to pour small water, not flood irrigation, otherwise it will destroy the seedlings, exposing the roots, affecting growth, resulting in lack of seedlings broken ridge. After fixing the seedlings, topdressing can be performed once. During fertilization, a small ditch is opened on both sides of the ridge, and 12 to 15 kg of ammonium sulphate is applied to Mushi. The soil is ridged and then watered. After the radish “breaks the shouldersâ€, it is necessary to top-dress fertilizer, water, and pests in order to promote growth. Apply 20-30 kg of ammonium sulfate per acre, apply a ditch to both sides, ridge the soil, and immediately water. When the third leaf ring is unfolded, timely cultivating should be carried out in a timely manner, and the light should not be deep. Otherwise, damage to lateral roots may affect growth. After 6 to 7 days, pour water once to keep the soil moist. Stop watering 8 to 10 days before harvest to facilitate harvesting. Fourth, before and after harvesting and storage, “Lidongâ€, the temperature gradually decreased, and the radish should be harvested in time. When harvesting, try not to scratch the skin, remove the top of the root, and dry it for 1 to 2 days for storage. At the time of storage, dig a pit in the sunny area, place the radish in layers and find signs of illness and take it out in time. After all the storage is completed, use 3 to 4 straws per square to tie together and cover 20-30 cm thick fine soil on the radish.
