Skilful Application of Irrigation Techniques in Grape Cultivation
Grapes require more water. To achieve high-quality, high-yield, and efficient production, it is necessary to irrigate timely and moderately to meet the water requirements throughout the grape growth period.
How to Water Grapes
Generally, grapes are buried in the soil to keep warm during winter, and they are exposed to wind and sun, leading to significant soil and water loss. To promote further differentiation of grape buds and flower buds, it is necessary to water once.
From the inflorescence stage to the flowering period, besides applying top dressing, water every 7-8 days. Sufficient water volume has a significant effect on promoting the growth of new shoots and increasing the flower clusters.
From the blossom drop to the physiological fruit drop, water every 5-6 days, combining top dressing with irrigation to promote the rapid and orderly development of young fruits and reduce fruit drop. This irrigation method is of great significance for high yield, quality, and efficiency of grapes.
Irrigation Methods During Drought
Water every 5-6 days during drought. In early and mid-August, when the fruits start to change color and rapidly expand, late-stage top dressing should be combined with irrigation to promote rapid expansion of the berries. If irrigation is insufficient at this time, fruit growth and development will be slow, and fruits are prone to cracking when encountering heavy rain or excessive irrigation.
Irrigation before maturity, combined with fertilization, watering once before the berries mature can supplement the insufficient water in the later stage of grape growth, improve grape yield and quality, promote fruit cluster maturity, and effectively prevent the occurrence of "soft tip" phenomenon.
To increase soil moisture, promote root growth, moisten the vines, and prevent grapes from drying out, grapes should be watered 2-3 times from harvest to protection from cold.
Do not water during the flowering period to prevent blossom and fruit drop. To improve the sugar content and quality of grape fruits, it is necessary to control the water content before and after coloring.
