1, germination period
The stage when garlic seeds are planted in the soil and wait for new leaves to grow is called germination stage, during which garlic seeds will grow roots and new leaves. Different varieties of garlic will grow new leaves at different times, which takes 7-30 days.
2. Seedling stage
Garlic will enter the seedling stage after germination, and the tender leaves that can't continue to grow will become flower buds. Leaves will gradually increase with the growth of roots, but the number will not increase. The root system will also grow from vertical to horizontal, and begin to grow lateral roots and fibrous roots to absorb nutrients from the soil.
3. Flower bud and bulb differentiation stage
After the young leaves of garlic become flower buds, they will enter the differentiation stage of flower buds and scale buds. It is a critical period for plant growth to irrigate compound fertilizer and turn green water in time to provide sufficient nutrients. When nutrients are insufficient, undifferentiated leaves will turn yellow, which will affect the yield.
4, garlic shoot extension period
After the flower buds of garlic are completely differentiated, they become garlic seedlings. Tillage weeding and continuous watering can increase the air permeability of soil, promote the growth of young garlic shoots, and also increase the toughness of leaves until watering is stopped three days before harvest.
5, garlic expansion period
After the young garlic shoots are harvested, they should be watered and topdressing with compound fertilizer. Nutrients that promote leaf growth will make garlic swell. At this time, it is necessary to build a sunshade to prevent garlic from being burned by too much light, and water and fertilizer should be suspended five days before harvest.
