The Growth And Development Cycle Of Garlic

The length of the growth cycle of garlic varies greatly depending on the sowing period. The growth period of garlic sown in spring is relatively short, generally 90~110d; garlic sown in autumn requires a certain number of days of low temperature vernalization, and the growth period is generally as long as 220~280d. Garlic generally uses bulbs as propagation material, and garlic generally uses bulbs as propagation material. Its growth process can be divided into six periods, namely, germination, seedling, bulb and flower bud differentiation, flower stem elongation, bulb expansion, and dormancy. . In addition, when aerial bulbs are used for reproduction, there is a growth period of aerial bulb enlargement after the underground bulb matures.

The period from sowing to the basal leaves growing out of the soil is the germination period. Generally, all garlic germinates 10-15 days after sowing. The roots of the germination period mainly grow vertically, the longest root is more than 1cm, and the number of roots is more than 30. . The period from the unfolding of the first true leaf to the beginning of the differentiation of flower buds and scale buds is the seedling stage. It only takes 25 days for spring sowing garlic to pass the seedling stage. Autumn sowing garlic includes the overwintering period, which requires up to 5-6 months of nutrition. Growth lays the material foundation for the differentiation of scale buds and flower buds. During the differentiation stage of bulb and flower buds, plant vegetative bodies fully grow, root growth is enhanced, plant height and leaf area growth is accelerated, and nutrient accumulation increases, which lays a material foundation for the growth of garlic sprouts and bulbs. After the flower bud differentiation is over, the garlic sprouts grow rapidly, and the scale buds begin to swell. The leaf area and plant growth reach the maximum, and vegetative growth and reproductive growth go hand in hand. This period is a critical period for the formation and development of product organs, and sufficient fertilizer and water should be ensured. After the garlic sprouts are harvested, a large amount of nutrients are transferred to the bulbs, and the bulbs expand rapidly. After the bulb matures, it enters a physiological dormancy period of more than 2 months.
