When can konjac be sown in spring
The growth and development temperature of konjac must be above 15℃. If it is lower than 10℃, it will be frozen. According to this, konjac production can be planted when the average temperature reaches 10℃ in spring.
Sowing too early, the soil temperature is too low, it is easy to suffer from freezing damage, the buds are damaged and shrink, and the bulbs are not easy to germinate and unearth.
If the sowing date is too late, the nutrient consumption is too much when the young buds germinate, and the rooting is slow, which is not conducive to the growth of konjac and shortens the bulb expansion period.
Sow in early April for areas below 700 meters above sea level; sown in mid-April for areas 700 to 1,000 meters above sea level; sown in late April for areas above 1,000 meters above sea level. The sunny slope land can be planted earlier in the suitable sowing period, and the shade slope land can be planted later. The flower konjac can be planted early, and the white konjac can be planted later.
