General autumn garlic growth period is relatively long, the time required 8-9 months. After the differentiation of scale bud and flower bud, the N, P and K uptake of garlic reached its peak, during which the leaves were luxuriant, the moss head grew rapidly, the yield was high, and the fertilizer and water requirements were large and concentrated. According to professional growers, every 100 kg garlic needs to absorb 1.42 kg nitrogen, 0.44 kg phosphorus and 0.99 kg potassium. In different growth and development stages, the absorption quantity and proportion of nitrogen, phosphorus and potassium nutrients also vary greatly.

Generally, scientific and reasonable fertilization should be carried out according to the soil fertility and the needs of garlic in different growth periods. Grasp the fertilization principle of "light before, medium and heavy after supplement", not only to prevent excessive growth in the early stage, but also to avoid premature aging in the late stage.

Garlic planting plots need deep ploughing and fine harrowing to enhance soil permeability, which is conducive to the activity of soil microorganisms and the transformation of soil nutrients, improve the storage capacity of soil, and is conducive to the development of roots and bulb expansion.

It is also the most critical topdressing in garlic life.

Therefore, the first topdressing should be carried out at the jointing stage, and 20~25 kg nitro-compound fertilizer can be applied per mu. After 15~20 days, apply fertilizer for the second time, and the application amount per mu is about 20 kg.
