- Abstract
In order to understand the effect of the appropriate ratio of base and topdressing fertilizers for water and fertilizer integrated irrigation on the yield and quality of garlic, the local purple garlic in Jiaxiang was used as an experimental variety, and different irrigation treatments were set under the fertigation condition with 20% reduction of fertilizer. The results showed that the water and fertilizer integrated irrigation treatment saved about 40.85 m3 of water per 667 m2 and the water-saving rate reached 52.50% compared with the conventional flood irrigation. Among different ratios of base and topdressing fertilizers and irrigation methods, the treatment of water and fertilizer coupling sprinkler irrigation, 60% basal fertilizers and 40% topdressing fertilizers had the best effect on yield increase. The yield of garlic sprouts and garlic increased by 14.48% and 10.89% compared with the conventional flood irrigation, respectively. Meanwhile, water and fertilizer integrated irrigation improved the quality parameters of garlic. Soluble protein and soluble sugar increased by 9.01% and 15.75% compared with the conventional flood irrigation, respectively. These results suggested that water and fertilizer integrated irrigation and optimizing ratio of base and topdressing fertilizers could reduce fertilizer and water usage and increase crop yields.
