The Fertilization Characteristics of Garlic
Garlic requires a lot of fertilizer and is tolerant during its development process. Increasing the application of organic fertilizer has significant benefits in increasing yield. In all stages of garlic development, it requires a lot of nitrogen, followed by potassium, and requires very little phosphorus. But the yield difference of garlic also inevitably leads to differences in nutrient absorption. According to actual evidence, when the yield per mu is 1570 kilograms, the absorption ratio of nitrogen, phosphorus, and potassium by garlic is generally 1:0.36:0.72. In manufacturing and management, adding fertilizer appropriately in proportion can significantly increase garlic's nutrient absorption.
Garlic growth is sensitive to trace elements such as sulfur, copper, boron, and zinc. Increasing the application of these trace element fertilizers can significantly improve the yield and quality of garlic. In addition, garlic has a weak root system, poor water absorption and fertilizer absorption ability, and requires a large amount of fertilizer. Based on this characteristic, when fertilizing, the principle of small amount and multiple times should be followed. After fertilization, water immediately to facilitate the absorption and utilization of fertilizer.
Garlic absorbs nutrients differently during different growth stages, and the amount of absorption is consistent with the plant's developmental status and foundation.
1. Seedling stage
Garlic requires less fertilizer during its seedling stage, and the source of nutrients needed for sprouting relies entirely on the storage of nutrients by the scales themselves. Moreover, in an environment where sufficient organic and chemical fertilizers are applied, there is no need for topdressing of the foundation during this stage.
2. Flower stem elongation period
The elongation period of the stem is a prosperous period for the nutritional development of garlic, and the absorption of nutrients rapidly increases. Before and after the harvesting of garlic stems, the balanced daily absorption of nutrients reaches Cenling. So, during this period, the focus of field management was on top dressing and water injection to meet the needs of flower and stem development, and to lay a foundation for garlic enlargement, to prevent premature plant aging and fertilizer deficiency during the garlic enlargement period.
3. Bulb enlargement stage
After the garlic sprouts are harvested, the development of the leaves stops at the base and enters a prosperous period of bulb enlargement. During this period, the focus of management is to reduce root damage, protect the leaves, prevent premature aging, ensure that the leaves continue to produce nutrients and transfer to the bulbs, and stimulate the expansion of garlic.
