Germination period refers to the germination of seeds until the first true leaf appears, and seedling period refers to the emergence of the first true leaf until the big bud begins to appear. Flowering period refers to the period from big bud to the first inflorescence, and fruiting period refers to the period from the first inflorescence to seedlings. The germination period of tomato refers to the germination of seeds until the first real leaf appears. The germination period of tomato is usually about 7-9 days.
During tomato germination, we should pay attention to controlling the temperature and humidity of the soil. Ensure the normal emergence and healthy growth of seedlings in the future, and avoid the phenomenon of long emergence time, weak seedlings or even rotten seeds. The seedling stage of tomato refers to the appearance of the first true leaf until the emergence of big buds.
Matters needing attention
If it is summer, the tomato seedling stage is generally about 45-50 days. If it is winter and spring, the tomato seedling stage is generally about 55-65 days. The basic vegetative growth stage is from the break of true leaves to the spread of two or three true leaves (that is, before flower bud differentiation), which lays the foundation for subsequent flower bud differentiation and further vegetative growth. But after spreading two or three true leaves, the flower buds began to differentiate and entered the stage of flower bud differentiation and development. From then on, vegetative growth and flower bud development proceed simultaneously.
Generally, the first inflorescence is differentiated about 25-30 days after sowing, the second inflorescence is differentiated about 35-40 days, and the third inflorescence is differentiated about 10 days. The flowering period of tomato refers to the period from the big bud to the first inflorescence. The flowering period of tomato is related to variety, seedling age and temperature after planting. During this period, the contradiction between vegetative growth and reproductive growth is more prominent, and it is necessary to coordinate the relationship between them.
