Miao Miao Dingmiao advocates early seedlings, late Dingmiao, the first time the seedlings fully developed in the cotyledons, commonly known as "broken flap." When the radish has two true leaves, that is "pull cross", the secondary seedlings are made. When the radish has 5-6 true leaves and the fleshy root begins to “break bellyâ€, the seedlings are stipulated according to the prescribed distance, leaving a healthy seedling in each pond.
In addition to cultivating seedlings and cultivating soil, radish should be cultivated 2-3 times during the whole growing period. The cultivator should be deep and shallow, first and then far, and stop cultivating after sealing. The purpose of cultivating is to loosen the soil, remove weeds, increase ground temperature, Promote root growth. Small radish planting density only in addition to seedlings, seedlings do not cultivator. When cultivating, combined with Qing ditch, the sloping soil will be raised on the surface of the sorghum.
After watering, it should be fully watered after sowing. Maintain soil moisture content more than 80%, seedling period root shallow and less, the water requirement is not large, should be poured less pouring, leaves grow vigorously, leaf area continues to expand, transpiration strengthens, fleshy roots also begin to expand, water demand, Can not be affected by drought. The roots of meaty roots are swollen and flourishing. At this time, the maximum amount of water is required and sufficient irrigation should be performed. The effective soil moisture content should be 70%-80%, otherwise bitterness and pungency will easily occur.
Top dressing is based on the application of base fertilizer, according to the growing conditions of radish for stage fertilizer, seedling stage and vigorous leaf growth, with nitrogen fertilizer, mu topdressing urea 10 kg or three yuan compound fertilizer 15 kg. During the vigorous growth of fleshy roots, additional phosphorus and potassium fertilizer should be added, and 30 kg of Mushi compound fertilizer should be added. Nitrogen fertilizers are banned 20 days before harvest.
