First of all, the growing environment in winter is beneficial to the growth of garlic. Garlic is a crop that likes cool climates, and the suitable growth temperature is between 12-26 degree . The warm climate in winter is conducive to the growth of garlic, especially when the temperature is 20-25 degree during the day and 10-20 degree at night, garlic grows the fastest 1. In addition, sufficient sunlight in winter is also conducive to the photosynthesis of garlic seedlings and promotes the growth of garlic seedlings 1.

  Secondly, winter growth helps to improve the yield and quality of garlic. The yield of winter-growing garlic is higher than that of spring-growing, because spring-growing garlic needs to wait until summer to be harvested, while winter-growing garlic can be harvested in April or May, which greatly shortens the planting cycle 2. In addition, the soil humidity of garlic grown in winter drops when the temperature gradually rises in spring. This change in the environment helps to improve the quality of garlic 2.

  Finally, winter growth can reduce the incidence of pests and diseases. Although the warm climate in winter is conducive to the growth of garlic, it is also easy to breed diseases and pests. Therefore, it is necessary to strengthen field management, prevent and control diseases and pests in time, and ensure the healthy growth of garlic 1.
