Garlic can be fertilized according to the characteristics of growth and development, fertilizer requirements, and fertilizer absorption. Garlic fertilizer should be dominated by organic fertilizers and supplemented by chemical fertilizers; base fertilizers should be used, and top dressing supplemented by fertilization to maximize the growth and development of garlic. The need for nutrients.
How to fertilize garlic?
The base fertilizer of garlic is best based on organic fertilizer. Common organic fertilizers include ring fertilizer, chicken manure, duck dung, manure, compost, and cake fertilizer. Whether the application amount of basal fertilizer is sufficient is directly related to the commercial nature of the garlic and garlic head and the overwintering performance of the plant, so the base fertilizer should be applied in production.
The application amount of basal fertilizer should be determined based on various factors such as the target yield of garlic and the amount of fertilizer required per unit area. Conditions can be applied to 50-100 kg of cakes, such as cottonseed cakes. Chemical fertilizers that are used in combination with organic fertilizers as the base fertilizer are usually superphosphate, nitrogen-phosphorus compound fertilizer, nitrogen-potassium compound fertilizer or ternary compound fertilizer. Apply about 75 kg of standard nitrogen fertilizer per 667 square meters.
Nitrogen fertilizer should have 2/3 of basal fertilizer and 1/3 of top fertilizer. Most of the phosphorus and potassium fertilizers are used as base fertilizers.
Phosphate fertilizer using about 30 kg of superphosphate. When phosphate fertilizer is used as base fertilizer, both superphosphate and calcium magnesium phosphate fertilizer must be mixed with organic fertilizer and ploughed into the tillage layer. The amount of potash applied is generally about 30 kg of potassium sulfate per 667 square meters.
The application of basal fertilizer is generally to apply half of the organic fertilizer to the front of cultivated land, spread it evenly on the surface of the soil, combine the cultivated land, and turn the fertilizer into the ground; the other half, when sowing, concentrates the furrow application and makes the fertilizer and soil phase. Mix and then sow. If ammonium bicarbonate or organic fertilizer is used as the base fertilizer, it should be buried in the trenches, or be applied with water, and the soil and fertilizer should be mixed evenly after application.
Phosphate fertilizer is best applied shallow, concentrated or layered. One part can be applied before arable land, and the other part is applied when cultivating garlic after planting, or shallowly applying 6-10 cm below the ground in order to facilitate the absorption and utilization of seedlings, cultivating strong seedlings and increasing the utilization rate of phosphate fertilizer in the season. Potash fertilizer can be used as farmland, and it can be turned into the ground when it is used with the farmland.
