| Abstract: |
| 【Objective】 In order to determine the effect of different basal dressing ratio and topdressing times on garlic yield and quality in the drip irrigation mode under mulch, 【Methods】 Zhongmou garlic was selected as the experimental variety, and different irrigation methods, basal dressing ratio and topdressing times were set under the condition of reducing inorganic fertilizer by 15%. 【Results】 The results showed that among different irrigation methods, basal dressing ratio and topdressing times, the treatment of 60% basal fertilizer and 40% topdressing under mulch drip irrigation had the most obvious effect on yield increase, the yield of garlic sprouts and bulbs increased by 12.68% and 14.80% respectively, and the allicin content, soluble protein and Vc increased by 12.22%, 29.80% and 10.68% respectively compared with the traditional flood irrigation. Nitrate content decreased by 10.62%. 【Conclusion】 The study shows that the effects of weight loss, water saving, yield increase and quality improvement of garlic planting can be achieved through drip irrigation under mulch, appropriate ratio of base to topdressing and number of topdressing. |
