Description

The method of burying the soil to prevent cold: Generally, the soil covering is about 20 cm when the low temperature is -15 °C in winter, and the soil covering is 25 cm when the temperature is -17 °C. the method of full burial on the ground is to bury the soil to prevent cold without digging trenches on the ground. The thickness of the covering soil depends on the local absolute minimum temperature and the cold resistance of the variety. The lower the temperature, the thicker the covering soil. For some varieties with strong cold resistance, such as Kyoho, white banana, etc., the covering soil can be slightly thinner.
