Garlic is a bulbous crop that requires large amount of fertilizer and is more tolerant to fat. It is suitable for cultivation in sandy loam soil rich in organic matter, loose and fertile soil surface, complete nutrition, and good water and fertilizer retention and ventilation. According to research, for every 1000 kg of fresh garlic produced, 4.5-5 kg ​​of nitrogen, 1.1-1.3 kg of phosphorus, and 4.1-4.7 kg of potassium are needed, and the ratio is 3:1:3. Therefore, on the basis of fully understanding the growth characteristics and fertilizer-demand characteristics of garlic, applying scientific fertilization is the key to achieving high quality and high yield of garlic.
According to the growth characteristics of garlic and the characteristics of required fertilizer, in the fertilization of garlic, it should be adhered to organic fertilizer, supplemented by chemical fertilizer; basal fertilizer should be the main, supplemented by top-dressing; the application of coarse fertilizer and chemical fertilizer should be the principle of fertilization. Satisfy the needs of nutrients in the growth and development of garlic.
How to Fertilize Garlic for High Yield
(1) Apply base fertilizer:
Because the garlic root is shallow, the root hair is few, and the ability of sucking fertilizer is poor, so the quality requirements for the base fertilizer (especially for the purpose of harvesting garlic and garlic) are relatively high. The decomposed manure or cake fertilizer should be used, and a certain amount of phosphorus and potassium should be added. Mixed fertilizer, usually 5000 kg of organic fertilizer per acre, 100 kg of cake fertilizer, 25-35 kg of NPK fertilizer.
(2) Early application of Miao Fei:
Early application of Miaofei helps to promote the rapid emergence of long-rooted seedlings after emergence of garlic, and improve the overwintering performance of autumn sowing garlic. The priming and replenishing fertilizer requirements are carried out about 15 days after emergence. In addition to the higher fertility and the base fertilizer, the urea can be applied to 15-20 kg per acre.
(3) Increase the return of green manure:
Returning green manure generally rises in spring, when garlic leaves and roots begin to grow, it is appropriate to apply 20-30 kilograms of urea per acre.

(4) Reapplying moss fertilizer:
Generally, it should be carried out when the scale buds and flower buds have been completely differentiated and the garlic moss is bred. Because at this time into the vigorous growth period, the amount of growth and fertilizer requirements have reached a peak, it is generally required to re-applied, accounting for about 40% -50% of the total topdressing, NPK fertilizer 25-30 kg per mu .
(5) Qiao Zhuang head fat:
Zhuangtou fertilizer should be carried out 25-30 days after the application of bolting fertilizer. Zhuangtou fertilizer should be dominated by nitrogen fertilizer, combined with a small amount of phosphorus and potassium fertilizer to meet the needs of garlic sprouts and garlic bulbs for nutrient expansion. Generally, high-nitrogen compound fertilizer is applied per mu. About kilograms.
The above is the method of high-yield fertilization of garlic. Planting garlic is a friend can refer to the above methods, combined with the specific planting conditions, and rationally study and apply fertilization.
