1, garlic has bulbs, which store enough nutrients for it to spread to garlic leaves and then carry out photosynthesis.

2. Seed germination is a normal phenomenon. Garlic is harvested in June every year, dormant in hot summer, and wakes up from dormancy and germinates and grows in autumn when the weather turns cold.

3. Seeds will germinate under conditions such as moisture, temperature and air.

Germination conditions of garlic

1, water is absolutely necessary for seed germination. With water, enzymes can move, nutrients stored in seeds can be hydrolyzed to produce effects, and cells can expand and elongate.

2. When seeds start to move, they need oxygen. So if they are watered too much, the seeds will rot, which is because of hypoxia. Only a few seeds of aquatic plants can germinate under hypoxia.

3. The germination temperature of plant seeds can range from 0-40℃, but each plant has its optimum temperature for germination, which is the most suitable temperature for germination. The optimum temperature for germination of plants varies from place of origin. Generally speaking, 15-20℃ is the most suitable temperature for temperate plants and 25-30℃ for subtropical and tropical plants.

Growth habit of garlic

1, temperature: like cold and cool, the suitable temperature is -5-26℃. The 4-5 leaf stage of Allium sativum seedlings has the strongest cold tolerance, and it is the most suitable winter in Miao Ling.

2. Illumination: Garlic in spring flowers begins to differentiate into flower buds and scale buds under the conditions of long sunshine and high temperature of more than 13 hours, and it is only suitable for the growth of stems and leaves in the short sunshine and cold environment.

3, moisture: like wet and afraid of drought.

4. Soil and nutrition: the requirements for soil are not strict, but fertile loam with rich organic matter, loose air permeability and strong water-retaining and drainage performance is more suitable.
