The Correct Way to Apply Sulfur Fertilizer for High-Yield Garlic

Edible Gardening 0 views
Garlic is a sulfur-loving crop. Allicin is mainly a disulfide compound. Most of the protein in garlic contains sulfur, and sulfur plays an important role in improving garlic quality. At the same time, studies show that only when the fertilizer N/S ratio is close to the optimal value can the nitrogen and sulfur absorbed by the plant be used most effectively. The N/S ratio in garlic is roughly 12/1. The utilization rate of sulfur in calcareous soils in the north is 2%-3%, and it is easily fixed as calcium sulfate, while the nitrogen utilization rate is 30%-35%. The optimal N/S is 4/5. Sulfur cannot be reused within the garlic plant, so sulfur must be supplemented in the middle growth stage to maximize the yield-increasing effect of the fertilizer. Choosing a suitable sulfur-containing fertilizer in production is the key to high yield. According to trials, applying 40% nitrogen-sulfur fertilizer (nitrogen-sulfur fertilizer contains N >= 17.5%, S >= 22.5%. Its fertilizer effect combines long-lasting and quick-acting effects, and the fulvic acid it contains plays an important role in promoting garlic root growth, improving disease resistance and fertilizer utilization rate, and eliminating soil compaction. It can combine root promotion and root nourishment, avoid premature aging and lodging of garlic, and achieve the production goals of increasing yield and marketability and building soil fertility) will be the best choice to meet garlic's needs. The specific fertilization methods are:

The specific fertilization methods are:

Supplementary application of green-up fertilizer: After garlic turns green, broadcast 15-20 kg of 40% nitrogen-sulfur fertilizer per mu, taking advantage of rainy or snowy weather.

Heavy application of seedling-promoting fertilizer: In early April (around Qingming Festival), apply 30-40 kg of 40% nitrogen-sulfur fertilizer per mu to meet the demand for nitrogen and sulfur during garlic's vigorous growth.

Skillful application of bulbing fertilizer: When the garlic scape emerges, flush-apply 15-20 kg of sulfur-containing high-nitrogen high-potassium fertilizer with irrigation water to accelerate bulb enlargement.
