What are the effects of integrated water and fertilizer management in grape applications?

Since the introduction of water-fertilizer integrated technology, China's water-fertilizer integrated technology systems and mechanisms have become increasingly mature and improved. Currently, most vineyards use integrated water-fertilizer technology that combines irrigation and fertilization, achieving significant results.
 

1. Improve water and fertilizer utilization efficiency

Traditional fertilization techniques lack scientific and reasonable basis. Excessive fertilization, on the one hand, leads to reduced yield and quality, and on the other hand, causes soil degradation and nutrient loss, leading to environmental imbalance. Water-fertilizer integration utilizes a method where fertilization and irrigation are carried out simultaneously. It uses a drip irrigation system to combine water and fertilizer, fertilizing during irrigation, maximizing fertilizer utilization efficiency. Compared with traditional fertilization methods, water-fertilizer integrated technology can save fertilizer, reduce water and fertilizer loss, and improve the utilization efficiency of fertilizer and water. Studies have shown that the use of water-fertilizer integrated technology can improve fertilizer utilization efficiency by 30%～50% and water utilization efficiency by 40%～60%.
 

2. Promote grapevine growth

Traditional watering and topdressing methods cause the crops to experience periods of starvation and overfeeding, hindering uniform nutrient absorption. Scientific water-fertilizer integrated technology, however, can provide nutrients as needed according to the crop's water and fertilizer requirements. It ensures continuous supply without overfeeding or starvation, changing from traditional flooding irrigation to small, frequent wettings of the plant roots, ensuring uniform nutrient supply and maintaining nutritional balance for grapes.

Studies have shown that irrigation of 4950m3/hm2 and fertilization of 960kg/hm2 can significantly increase the growth of new shoots, berry expansion, and bunch growth in wine grapes, and also significantly increase the fresh-dry ratio of grape leaves and petioles. Under this scheme, the effective utilization of water, stomatal conductance, photosynthetic rate, and transpiration rate are highest. Irrigation of 6450m3/hm2 and fertilization of 960kg/hm2 can significantly increase the length of secondary shoots, NDV1 value, and SPDA value, and significantly improve plant height, single berry weight, and yield.

Research on seedless white chicken heart grapes shows that treatments with higher soil moisture content and higher nitrogen fertilizer proportions result in faster growth of new shoots and thicker stems. Therefore, reasonable fertilization and irrigation not only reduce fertilizer waste but also can regulate the vegetative and reproductive growth of grapes, thus achieving high efficiency and high yield.

3. Improve economic benefits

The application of water-fertilizer coupling technology ultimately lies in its impact on fruit quality. Studies have shown that the application of water-fertilizer coupling technology can increase yield, improve quality, and improve economic benefits. Researchers applying water-fertilizer integrated drip irrigation technology to the production of southern red globe grapes achieved 31.8% water saving, a 6% increase in fruit setting rate, and a yield increase of more than 10%; In Zhaoyuan City's grape drip irrigationWater-fertilizer integrated equipmentApplications show that water-fertilizer integrated technology significantly increases grape yield, saves fertilizer, and promotes economic benefits.

Studies on water-fertilizer integrated technology in the main grape-producing areas of Hebei Province show that drip irrigation significantly increased grape yield, increased the content of soluble solids in the fruit, reduced acidity, improved grape quality, and significantly improved water use efficiency and fertilizer use efficiency. Researchers found that the water use efficiency of deficit irrigation was 59.0% higher than that of ordinary drip irrigation, the water requirement was reduced by 46.0%, and the yield was reduced by 13.8%, but the grape quality was greatly improved; In the study of water-fertilizer coupling effects on drip-irrigated grapes in the northern Xinjiang region, the effects of water-fertilizer coupling on grape growth, yield, fertilizer and water utilization efficiency, and economic benefits were systematically investigated. The results indicated that reasonable irrigation and fertilization can increase yield and improve grape quality.
