3, cultivation techniques

Because the root system is well developed and is mainly distributed on the surface soil layer, the sandy loam soil with fertile soil, PH 6.5 or so, drainage and irrigation, and the former is a non-cruciferous crop should be selected for the cultivation field. Before sowing, apply basal fertilizer (seeds can be spread evenly with fine soil). After leveling the soil, make a 1.5-meter-wide hoe. Pour plantar water on the day before sowing and sow about 500 grams per acre on the next day.
(2) After sowing, the field management will be cut with steamed buns and then compacted, so that the seeds will be in close contact with the soil to reduce the evaporation of soil moisture, so that the seeds germinate and sprout quickly and neatly, and then the weather and soil Watering in the wet and dry state requires that the soil always maintain a certain humidity, and top dressing is performed according to the growing trend to ensure that the plants grow robustly. After the high temperature season, it is best to cover the shade net in time to reduce the temperature and maintain the humidity so as to prevent direct sunlight and heavy rain erosion.
(3) Pest and disease control Pests and diseases mainly include downy mildew, soft rot, diamondback moth and aphids, which should be controlled in time.
