Grapes are shrubs, with an average life span of about 60 years. The length of life is related to species, region, climate and nursing methods, and the longest life can reach 100 years or more.
Grape growth process
The growth of vines depends on the season. In March of spring, they begin to sprout and their leaves are green. In May of spring, grapes will bloom, first showing a string of small yellow buds, then bearing fruit in July and maturing in mid-August.
How much can the vines grow in a year?
Generally speaking, vines can grow about 1-2 meters a year, but this speed is not completely fixed. At first, they grew very slowly, only about one meter. When they are 3-4 years old, their growth will start to accelerate, and when they are too old, they will start to slow down.
Grape life cycle
1. Juvenile period: from seed germination to early flowering of young fruit, from planting to normal fruiting of grape seedlings. Vegetative growth period: root cap and root system grow rapidly through centrifugation, photosynthesis is enhanced, and assimilate accumulation is gradually increased.
2. Early fruiting period: the first normal fruiting period ends in the complete fruiting period. Vegetative growth and reproductive growth: the crown and root system expand rapidly, reaching or approaching the predetermined nutritional area, the leaves are larger than the fruits, flower bud differentiation is easy to form, and the yield increases year by year.
3. Peak fruiting period: from normal yield to gradually decreasing yield, high and stable yield stage: the crown is the largest, the yield is high, the consumption is high, and the growth of branches and roots is inhibited.
4. Late stage of results: the yield decreased obviously until there was no economic benefit, the tissue aged, the function decreased, toxic substances were produced around the roots, a large number of shoots sprouted, and pests and diseases increased.
5. Aging period: there is no economic benefit until most plants fail to bear fruit normally, until death, soil exhaustion, tissue necrosis and no renewal value.
