A new method of purple cabbage management:
Purple cabbage setting
Everyone knows that the purple cabbage must be applied before the fixed value, including flying organic fertilizer, diammonium phosphate and potassium sulfate, ridge planting.
Temperature control must be carried out after the setting, the general temperature should be controlled at 25-27 degrees, and the night control at 13-15 degrees.
Growth period management
The cabbage must enter the rosette and the ball-forming period to control the temperature. During the daytime, it should be at 18-20°C and 12-15°C at night. The temperature should not be too high or too low. If the temperature reaches 25 degrees during the day, it should be properly windproof and cool down. Ensure that purple cabbage grows better. 15 days after the purple cabbage is slowed down, it can be combined with watering for topdressing and urea application.
The second top dressing is very important. Before the lotus leaves are closed and the leaves begin to conceive, the top dressing is carried out with urea and potassium sulfate.
When purple cabbage is in the ball, be sure to keep the soil moist. Choose watering in sunny weather.
Pest Control
Purple cabbage has fewer pests and diseases, and it is generally found that purple cabbage disease plants are pulled out in time, and then the pesticides can be sprayed.
