As an important vegetable crop, the fertilization management of garlic during its cultivation is essential to improve yield and quality. Fertilization management is equally important after garlic mossing, as this is the time of the garlic growth cycle when the nutrient requirements are at their highest. This article will introduce in detail the key points of fertilization management after garlic mossing, so as to help farmers apply fertilizer reasonably and improve the yield and quality of garlic.
1. Characteristics of nutrient requirements of garlic
Garlic is a crop that requires more fertilizer, and has a large demand for nutrients such as nitrogen, phosphorus, and potassium throughout the growth cycle. Among them, nitrogen is particularly important for the growth of garlic, which can promote the development of leaves and garlic heads. After garlic mossing, nutrient requirements peak due to the simultaneous occurrence of reproductive growth and vegetative growth. Therefore, fertilization management requires special attention at this time.
Second, the importance of fertilization after mossing
After the garlic is mossed, the plant enters the reproductive growth stage, and the garlic begins to expand rapidly. At this time, garlic has an increased demand for nutrients such as phosphorus and potassium, especially potassium, which can promote the development of garlic and the accumulation of sugar. Therefore, fertilization management after moss extraction is essential to improve garlic yield and quality.
Third, the key points of fertilization management
1.Fertilization time: After garlic moss, it should be fertilized in time. Generally, fertilization is done within 1-2 weeks after moss extraction, when the nutrient requirement of garlic is maximum.
2.Fertilizer type: Mainly organic fertilizer and chemical fertilizer, the amount of fertilizer can be determined according to soil fertility and target yield. It is recommended to apply 2000-3000 kg of organic fertilizer and 30-50 kg of potassium sulfate compound fertilizer per mu. At the same time, it can be combined with the application of trace element fertilizers, such as zinc sulfate, manganese sulfate, etc.
3.Fertilization method: The method of strip application or hole application is used to apply fertilizer between the rows. First make a trench or dig a hole 10-15 cm deep between the rows, and then apply the fertilizer evenly into the trench or hole. Be careful not to sprinkle the fertilizer directly on the leaves so as not to burn the leaves.
4.Irrigation: Irrigation should be carried out in time after fertilization to promote nutrient absorption and utilization. The amount of water should not be too large when irrigating, so as not to cause soil compaction and garlic rot.
5.Pest control: In the fertilization management, we should pay attention to the prevention and control of pests and diseases. Regularly check the growth of garlic, and take timely control measures when pests and diseases are found. Common pests and diseases include garlic rust, leaf blight, root maggots, etc., which can be controlled by chemical agents or biological control.
Fourth, reasonable crop rotation and soil improvement
In addition to reasonable fertilization management, reasonable crop rotation and soil improvement are also important measures to improve the yield and quality of garlic. Before planting garlic, suitable stubble should be selected for crop rotation to avoid soil nutrient imbalance and aggravation of pests and diseases caused by heavy cropping. At the same time, the soil structure is improved through deep tillage and increased organic fertilizer, and soil fertility is improved, so as to create good environmental conditions for the growth of green onions.
5. Other precautions for planting management
1.Weeding: During the growth of garlic, weeding should be done in time to prevent weeds from competing with garlic for nutrients. Weeding can be done by hand or with chemical herbicides. Pay attention to the selection and use of herbicides to avoid pesticide damage to garlic.
2.Pest control: Regularly check the growth of garlic, and take timely control measures when pests and diseases are found. Common pests and diseases include garlic rust, leaf blight, root maggots, etc., which can be controlled by chemical agents or biological control. Pay attention to the rational use of pesticides to avoid pollution to the environment and products.
3.Harvesting: When the garlic grows and the garlic leaves are yellow, they should be harvested in time. Damage to garlic heads and leaves should be avoided during harvesting to avoid affecting quality. At the same time, it is necessary to pay attention to the treatment and storage of garlic after harvest, keep it dry and well-ventilated, and prevent problems such as mildew and insect moth.
In conclusion, fertilization management after garlic moss extraction is one of the key measures to improve yield and quality. Through the integrated management measures of reasonable fertilization, pest control, reasonable crop rotation and soil improvement, the growth and development of garlic can be effectively promoted, and the yield and quality can be improved. At the same time, farmers should also pay attention to other aspects of planting management, such as weeding, harvesting and other management points. Through scientific and reasonable planting management technology, high-quality garlic products can be obtained, bringing better economic and social benefits to farmers.
