Swirl vegetables like hot and humid, strong heat resistance, intolerance to frost, frosted stems and leaves withered, growth temperature is 25 ~ 30 °C, growth stagnation below 10 °C, so winter should use plastic greenhouses for off-season cultivation. 1. Variety Selection The varieties that are suitable for planting include large chicken yellow, big bone blue, flag leaf, silkworm, big chicken blue and so on.
