Garlic is one of the widely cultivated vegetables that requires adequate nutrients during its growth. After moss extraction, the garlic enters the bulb formation stage, and the demand for nutrients increases. Therefore, proper fertilization is essential for the growth and yield of garlic. This article will introduce in detail how to fertilize garlic after mossing, in order to provide a useful reference for farmers.
1. Characteristics of garlic fertilizer after mossing
After the garlic is mossed, it enters the bulb formation stage, which is a critical period for garlic growth. At this stage, garlic needs more nutrients to support its rapid growth, especially the increased demand for elements such as nitrogen, phosphorus, and potassium. At the same time, the absorption of nutrients by garlic also changed, and the absorption of phosphorus and potassium gradually increased, while the absorption of nitrogen gradually decreased. Therefore, it is necessary to apply fertilizer reasonably according to the fertilizer demand characteristics of garlic.
2. Fertilization technology after garlic mossing
1.Amount of fertilizer.
According to the characteristics of garlic fertilizer demand and soil fertility, determine the reasonable amount of fertilizer. Generally speaking, 2000-3000 kg of farm fertilizer and 40-60 kg of compound fertilizer need to be applied to each mu of garlic. Farmyard manure can increase soil organic matter content and improve soil structure;Compound fertilizers can provide a comprehensive range of nutrients to meet the needs of garlic growth.
2.Fertilization method.
After the garlic is mossed, it should be fertilized in time. First, the farmyard manure is spread evenly on the surface of the field, and then the fertilizer is mixed with the soil using tillage machinery. For compound fertilizer, due to its high nutrient content, it should be avoided to burn seedlings due to excessive application. Therefore, when fertilizing, the compound fertilizer should be divided into several parts according to the size and shape of the field, and applied to the field one by one. In addition, in order to improve fertilizer efficiency, irrigation can be carried out after fertilization.
3.Trace element fertilizers.
In addition to macro-element fertilizers such as nitrogen, phosphorus, and potassium, garlic growth also requires some micro-element fertilizers, such as iron, boron, zinc, etc. These trace elements play an important role in the growth and yield of garlic. If these elements are deficient in the soil, the corresponding micronutrient fertilizers need to be applied in a targeted manner. For example, iron deficiency can lead to yellowing of leaves, boron deficiency can lead to poor development of flower organs, etc. Therefore, when fertilizing, trace element fertilizers should be supplemented in an appropriate amount according to soil conditions and growth in previous years.
3. Precautions
1.Avoid over-fertilizing.
Although garlic requires a large amount of fertilizer, excessive fertilization can easily lead to seedling burning, which affects the growth and yield of garlic. Therefore, it is necessary to control the amount of fertilizer when fertilizing and avoid excessive fertilization. At the same time, it is also necessary to pay attention to balanced fertilization to avoid nutrient imbalance caused by partial application of certain elements.
2.Rational irrigation.
After fertilizing the garlic, irrigation should be carried out in a timely manner. On the one hand, it can improve fertilizer efficiency and promote nutrient absorptionOn the other hand, it can reduce the soil salinity concentration and prevent the effect of salinization on the growth of garlic. At the same time, according to the weather conditions and soil moisture, the irrigation time and water should be reasonably arranged.
3.Pest and disease control.
In the process of garlic growth, the control of pests and diseases is also very important. It is necessary to regularly check the growth of garlic, and take timely control measures when pests and diseases are found. Commonly used control methods include chemical control, biological control and agricultural control. When using chemical control, it is necessary to choose pesticides with low toxicity and low residue to avoid affecting the environment and human health.
Fourth, summary
In conclusion, fertilization management after garlic moss extraction is one of the key measures to improve garlic yield and quality. In the process of fertilization, a reasonable fertilization plan should be formulated according to the characteristics of garlic fertilizer, soil conditions and growth in previous years. At the same time, attention should be paid to avoiding problems such as excessive fertilization, rational irrigation, and pest control. Only in this way can the goal of high yield, high quality and high efficiency of garlic be achieved.
