High-yield irrigation of grapes is critical, and it is important to grasp the initial stages of grape growth, the early flowering period, the post-flowering period, the berry period, the berry expansion period and the six periods after the grape harvest. Of course, we must pay attention to increasing or decreasing the number of irrigations according to the amount of precipitation in the current year.
Embryonic stage: Watering before the grapes are unearthed and sprouted. In drought-scarce areas in spring, it is also necessary to fill once with permeable water to meet the needs of budding and sapling of grapes. At the same time, the new high-fat membrane can be sprayed to protect the water from evaporation, sun protection, drought and heat preservation.
In the early flowering period before flowering, water is irrigated before and 10 days after flowering. Before flowering, the flower fertilizer is applied in combination, and the fertilizer is dissolved in water and can be quickly absorbed by the root to promote the rapid growth of the inflorescence, ovary and pollen. And with spraying strong fruit turmeric, increase fruit pedicle, improve nutrition delivery. Anti-drop, fruit drop, cracked fruit, stale fruit, malformed fruit, improved pollination quality and fruit setting rate.
Berry period: When the berry grows to the size of the bean, the new shoot also grows vigorously. At this time, the temperature keeps rising, the leaf water evaporates more and more, and nutrients and moisture are urgently needed. Therefore, in late June, it is necessary to combine the application of fruit fertilizer to stimulate fruit and water. When there is little rain at this stage, the water should be poured every 7-8 days, and with spraying 800 times the new high-fat membrane, water vaporization, sun protection drought, to meet the needs of new shoots and berry growth.
Berry enlargement period: In the berry period before the ear matures, the berry ripening water is applied once in combination with fertilization to supplement the lack of moisture in the late growth period of the grape. In conjunction with spraying the fruit to increase the yield and quality of the grapes, the fruit is colored beautifully. Fruit-type beauty, good taste.
Postharvest period: The fruit should be filled with 2 or 3 times of water before harvesting to prevent the cold, in order to improve the soil moisture, promote the growth of the root system, moisten the shoots, and prevent draining. Simultaneously spraying new high-fat membranes restores plant physiology and promotes plant growth. In arid regions, the frozen winter water must be allowed to air for 2 to 3 days after it is poured. After the surface soil is dry, it will be buried and protected from the cold to prevent the humidity of the soil from being excessive, causing the bud eyes to rot.
