Warm and humid climate conditions, bulb growth suitable temperature 18-22 degrees Celsius during the day, about 10 degrees Celsius at night, bulbous expansion in the case of high temperatures above 30 degrees Celsius, easy to fibril meat; adequate light growth robust, high yield, good quality; Hi moist soil and air conditions, such as insufficient water during bulb expansion will reduce the quality and yield; the most suitable for loose, fertile, good ventilation of the loam plant, the need for nitrogen, phosphorus, potassium and trace elements in combination. Second, the planting season. Appropriate for planting in spring, autumn and spring, autumn and winter.
