Abstract: 【Objective】To investigate the effect of foliar application of silicon.【Methods】A field experiment was conducted on the growth characteristics,yield,and quality of single-clove garlic in Xuzhou,Jiangsu Province.【Results】The experimental results revealed that the foliar application of 5 mmol/L sodium silicate solutions could improve the above ground morphological index of garlic plants,increase the yield and commercial characteristics of single-clove bulb,but also affect their single-clove ratio and nutritional quality. Compared to the control treatment,the plant height,leaf length,leaf width,pseudo stem height,pseudo stem diameter,and functional leaf number of the silicon treated plants increased by 17.24%,14.47%,5.41%,10.58%,9.66%,and 9.35%,respectively. The single-clove bulb ratio decreased by 1.97%,the bulb weight increased by 8.01%,the yield and quantity of high-grade bulbs increased by 21.85% and 29.99%,compared with low-grade bulbs which decreased by 14.93% and 11.31%,respectively. The dry matter contents and rate of the single-clove bulbs increased by 9.72% and 2.10%,respectively,and the allicin content increased by 5.25%,but the concentration decreased by 2.14%.【Conclusion】 The results showed that the foliar silicon application has a certain application value in the production of single-clove garlic in Xuzhou City.
