Germination stage, seedling stage, flower bud differentiation stage of scale bud, garlic moss extension stage, bulb expansion stage and dormancy stage.
The suitable growth temperature of garlic is -5 ~ 26℃, and 4~5 leaves of garlic seedling have the best cold resistance. Under the conditions of short light, low temperature and low temperature, it is suitable for the growth of stems and leaves. Only under the conditions of long light 13 hours and high temperature can buds germinate and differentiate. The soil is required to be loose, breathable, fertile and moist.
Growth stage:
1, the leaf is in the embryonic stage, usually about 7-30 days, and then the leaf area will increase with the growth. Then there is the stage of bud and scale bud differentiation, which is the most important reproductive stage. When they are completely differentiated, it is the growth stage of garlic seedlings, then the spherical expansion stage, and the garlic at the bottom will also become bigger. When plants dry up, they go into a dormant state.
2. The growth period of garlic varies with sowing time. The results showed that the growth cycle of spring garlic was 90~ 100 days, and that of autumn garlic was 220~240 days. It usually takes 10- 15 days from dormancy to germination of primary leaves. There is no differentiation from germination stage to leaves. The flowering period of garlic in autumn is 5-6 months, while there are only 25 garlic seeds planted in spring.
3. The differentiation stage of flower bud and scale bud is from the initial stage of flower bud and scale bud differentiation to the final stage. The elongation period of garlic moss is a period caused by the elongation of garlic bolts, that is, the early stage of scale bud expansion, which takes about 30 days. Scale bud expansion period refers to the period from scale bud differentiation to bulb harvest, and the extension period of garlic moss occurs about 30 days ago.
