1. Seedlings, Dingmiao: When the seedlings emerged, the first thinning was performed when the cotyledons were unfolded; 3 to 4 true leaves were grown and the second thinning was performed; when the seedlings had 5 to 6 leaves, the fleshy root of the radish broke. Start seedlings, leaving only one strong seedling per hole.

2. Intertillage and weeding: The combination of thinning and cultivating the seedlings is performed in the first time and then the ploughing is performed. At the same time, the soil in the hoe ditch is cultivated on the sorghum surface to prevent the seedlings from falling.

3. Timely irrigation: In summer, the temperature is high and the water evaporates quickly. Therefore, water should be properly watered according to the soil moisture and the characteristics of the radish during each growth period. In the seedling stage, the seedling roots are shallow and the water requirement is small. It is necessary to grasp the principle of “less pouring and dilute”; in the period of leaf growth, it is necessary to grasp the principle of “appropriate watering” and not be able to water too much; during the period of root enlargement, it is necessary to grasp “ The principle of full and uniform water supply is to maintain the soil moisture at 70% to 80%. Note: Summer radish avoid watering at noon, it is best to water in the evening.

4. Fertilizer application: After tying seedlings, combine watering with 8 kg ~ 12 kg of urea per acre to promote the growth of leaves; In the early stage of fleshy root expansion, that is, after the bare shoulders, the amount of urea or ammonium sulfate 15 kg to 20 kg can be applied with water. , Potassium sulfate 10 kg ~ 15 kg. In addition, this period, if combined with the top dressing and then spraying fertilizer 2 to 3 times, will effectively promote the root swelling.
