What conditions are needed to grow grapes?
Grapes are one of the common fruits in people's daily lives, with a sweet-and-sour taste and rich nutritional value. So, what growing conditions do grapes need? Let's find out together!
1. Soil
Although grapes are not strict about soil requirements and can grow in all kinds of soil, such as saline-alkali and sandy wasteland areas, different soils have different effects on their growth and fruiting. Suitable soil makes them grow more vigorously, bear more fruit, and produce better-tasting fruit. Therefore, soil is extremely important for grape growing. Sandy soil or loam that is loose, fertile, and well-drained is best. Sandy soil has excellent air permeability, which is extremely beneficial for plant growth, but its water- and fertilizer-holding capacity is poor, which can cause loss of water and nutrients, so planting requires careful management. Loam has a stronger water- and fertilizer-holding capacity and can improve the quality and yield of grapes.
2. Temperature
Grapes are not cold-tolerant and have relatively strict temperature requirements. Their growing temperature must not be lower than 12 degrees; below 12 degrees they stop growing, which affects fruiting. Their flowering temperature is around 20 degrees, which is favorable for blooming. During fruit enlargement, a temperature of 20-30 degrees is needed. In addition, during the fruiting period, the greater the temperature difference between day and night, the more favorable it is for grape coloring and sugar accumulation.
3. Light
Grapes are light-loving plants and need sufficient light conditions for growth. This is also the reason most grapes are grown in the Northern Hemisphere. The stronger and more abundant the light, the greater their photosynthesis, which is favorable for grape sugar accumulation and promotes rapid ripening, allowing them to be marketed earlier than other grapes and bringing higher profits. With insufficient light, photosynthesis is poor, and the plants tend to grow weaker and shorter, with thin, yellowing branches and leaves. The fruit produced is often of poorer quality, not sweet enough, and relatively sour in taste.
4. Water
Grapes have relatively high water requirements, especially in the early growth stage, when the demand for water is extremely high. But in the later growth stage and fruiting stage, they require less water. Too much watering or rain in the later stage can damage the plant's root system and affect quality and yield. In addition, growing in areas with more rain can cause insufficient light for grapes, limiting photosynthesis, and ultimately causing various diseases due to excessive water absorption. Therefore, when growing in water-scarce and relatively arid areas, attention should be paid to watering and moisture-retention measures, while in areas with more precipitation, attention should be paid to drainage and rain-protection measures.
The world's famous grape-producing regions are almost all at similar latitudes and altitudes. Good growing conditions are needed to grow delicious grapes. The above is the grape growing conditions compiled for you by the Tudiu.com editor. We hope it can help you!
