Garlic is a fertilizer-tolerant crop. On the basis of applying the base fertilizer, topdressing is still needed in spring. The total amount of top dressing in high-yield fields is controlled at 25 kg of pure nitrogen and 10 kg of potassium. Fertilization should master the strong growth period of nutrition (the middle of April) is the maximum efficiency period of nitrogen fertilizer. The period of garlic expansion (Guyu~Lixia) is the maximum efficiency period of potassium fertilizer, and the nutrients required for leaf formation are mainly nitrogen, and the deficiency of nitrogen The greater the rate of early reduction. During the expansion period of garlic, the lack of potassium appeared in the early stage, and the influence was large in the later stage. The elongation period of garlic stalk is the maximum period of nutrient absorption of nitrogen, phosphorus and potassium.
Garlic is a sulphur crop. Allicin is mainly a disulfide compound. Most of the protein in garlic contains sulfur, which plays an important role in improving the quality of garlic. At the same time, studies have shown that only when the fertilizer n/s is close to the optimal value, the nitrogen and sulfur absorbed by the plant can be most effectively utilized. The n/s in garlic is roughly 12/1. The utilization rate of sulfur in the northern calcareous soil is 2 to 3%, and it is easily fixed to calcium sulfate, and the nitrogen utilization rate is 30 to 35%. The optimum n/s is 4/5. Sulfur is not reusable in garlic. In the middle of growth, sulfur must be added to maximize the fertilizer effect. According to the demand for nitrogen and sulfur in garlic, 40% nitrogen and sulfur fertilizer was selected (n≥17.5%, s≥22.5%). The fertilizer has long-term complementary effects, and contains fulvic acid, which plays an important role in promoting garlic root growth, improving disease resistance and fertilizer utilization rate, and can promote the combination of rooting, avoid premature aging, and increase yield.
Replenishing the application of green fertilizer: After the garlic is green, it can be applied to 40% of the nitrogen and sulfur fertilizer in the rain and snow.
Heavy application of seedling fertilizer: In the first ten days of April, 40% of nitrogen and sulfur fertilizers were applied to 20 to 30 kilograms to meet the demand for nitrogen and sulfur in the vigorous growth of garlic.
Applying the swelled fertilizer: When the garlic is exposed, the high-nitrogen and high-potassium fertilizer is applied with water 15-20 kg to accelerate the expansion of the garlic.
