The application of garlic base fertilizer is mainly organic fertilizer, and fertilization is carried out according to the growth and development of garlic and the characteristics of fertilizer demand and fertilizer absorption, which can lay the foundation for high yield of garlic. Organic fertilizer usually refers to circle manure, chicken manure, duck manure, manure, compost, cake fertilizer, etc. Whether the amount of basal fertilizer is sufficient is directly related to the commercialization of garlic and the overwintering performance of the plant, so sufficient basal fertilizer is applied to garlic in production.
The application rate of basal fertilizer should be determined according to various factors such as the target yield of garlic and the fertilizer requirement per unit area yield. It is required to apply 2500 kg ~ 3000 kg of pigsty fertilizer per mu, or 4500 kg ~ 5000 kg of manure. Conditionally, 50 kg ~ 100 kg of cake fertilizer such as cottonseed cake can be applied. Alfalfa and other green manure crops can also be used as base fertilizer. The chemical fertilizers used with organic fertilizers as base fertilizers are usually superphosphate, nitrogen and phosphorus compound fertilizers, nitrogen and potassium compound fertilizers or ternary compound fertilizers.
About 75 kg of standard nitrogen fertilizer is applied per 667 square meters. Nitrogen fertilizer should be applied 2/3 as basal fertilizer and 1/3 as top dressing. Most of the phosphorus and potassium fertilizers are applied as basal fertilizers. About 30 kg of superphosphate is used for phosphate fertilizer. When phosphate fertilizer is applied as basal fertilizer, whether it is superphosphate or calcium-magnesium phosphate fertilizer, it should be mixed with organic fertilizer, and shallow tillage should be turned into the tillage layer.
Half of the organic fertilizer is applied before the cultivated land, evenly spread on the soil surface, combined with the cultivated land, and the fertilizer is turned into the ground; The other half is sown in a concentrated furrow application, and the fertilizer and soil are mixed, and then the seeds are sown. If ammonium bicarbonate or organic fertilizer is used as base fertilizer, it should be buried in a ditch, or watered with water, and after application, it should be combined with land preparation to mix fertilizer and soil evenly.
Phosphate fertilizer application is best done shallowly, intensively or layeredly. Part of it can be applied before cultivated land, and the other part can be applied when planting garlic after ploughing, or shallow application at 6 cm ~ 10 cm below ground after land preparation, which is conducive to the absorption and utilization of seedlings, cultivating strong seedlings, and improving the utilization rate of phosphate fertilizer in the current season. Potash fertilizer can be applied with the cultivated land when cultivating the land, and it can be turned into the ground.
How to apply garlic-based fertilizer is introduced here, I hope it will be helpful to everyone. If you want to buy high-quality and high-yield garlic seeds, you can download the seed bank App, and the country's excellent garlic varieties are for you to choose.
