Nutritional characteristics
Garlic is one of the vegetables that require more fertilizer and is more tolerant to fertilizers. In general, it requires 4.5 to 5 kg of nitrogen per 1,000 kg of garlic, 1.1 to 1.3 kg of phosphorus, and 4.1 to 4.7 kg of potassium, and the ratio is 3:1:3. The absorption of nutrients by garlic increases with the increase in plant growth. However, the root hair of garlic is small and weak, and the ability of sucking fertilizer is poor, and it is sensitive to the response of fertilizer and water. The period from sowing to the emergence of the primary leaves is the germination period of garlic. During this period, the growth is small, the growth period is short, and the nutrients consumed are also small. The various nutrients needed are provided by the kind of garlic. The main role of the root system during this period is to absorb water. From the primary leaves to the scale buds and flower buds, they begin to differentiate into the seedling stage. With the growth of the seedlings, the nutrients stored in the seed flaps are gradually depleted, and the garlic mothers begin to shrink, which is commonly known as the "mother". During this period, the growth of garlic depends entirely on the nutrient supply of the soil, and the amount of sucking fertilizer is significantly increased. If the soil nutrient is insufficient, the plants are prone to appearing green and yellow without showing the dry tips of the leaves. At this time, quick-acting fertilizers should be applied to ensure the growth of seedlings and the cultivation of strong seedlings. After the seedling stage, the scale buds and flower buds have entered the differentiation period. This period is a critical period for the growth and development of garlic. The growth of roots is enhanced, which accelerates the absorption and utilization of soil nutrients. From the end of flower bud differentiation to harvesting garlic pods, it is the period between vegetative growth and reproductive growth of garlic. While garlic pods are rapidly elongating, the bulbs are gradually formed and expanded, the amount of growth is large, and the amount of water needed for fertilizers is also the highest. At this time, root growth and uptake of fertilizers are maximum. The peak of capacity is a critical period for garlic fertilizer management. After the harvest of garlic bulbs, it is the peak of bulb expansion. At this time, the root system begins to age and the amount of fertilizer is small. The nutrients needed for bulb expansion are mostly from the redistribution of their own nutrients.
In addition to absorbing nitrogen, phosphorus, and potassium, garlic also has a relatively large demand for calcium, magnesium, and sulfur. In particular, sulfur and sulfur play an important role in improving the quality of garlic. Appropriate application of sulfur fertilizer can increase the growth of garlic and garlic pods. Reduces malformed garlic sprouts and fissure balls.
Fertilization technology
According to the requirements of garlic for fertilizer and sucking fertilizer, in the fertilization of garlic, it should be adhered to organic fertilizer, supplemented by chemical fertilizer; basal fertilizer should be dominant, supplemented by top dressing; the principle of fertilizer application should be applied to maximize the use of fertilizer. Satisfy the needs of nutrients in the growth and development of garlic.
base fertilizer. Because the garlic root is shallow, the root hair is less, and the ability of sucking fertilizer is poor. Therefore, the quality of the basal fertilizer is required to be high. Generally, the organic fertilizer is good, 5000-6000 kg per mu, and 50-100 kg compound fertilizer. Usually in the base fertilizer with some calcium, magnesium, sulfur fertilizer.
top dressing. Garlic is a fertilizer-resistant crop. On the basis of applying base fertilizer, four fertilizers are generally applied. They are:
Seedling-emergence fertilizer: generally about 15 days after emergence, each acre can be applied with high-nitrogen compound fertilizer 5-8 kilograms. The fertility is higher and the base fertilizer is more than sufficient.
Returning green manure: Generally, the temperature rises in spring, when the heart and root of garlic are started to grow, it is applied around the vernal equinox, and the amount of mu is 8 to 10 kg of high-nitrogen compound fertilizer.
Pumping manure. Generally, it should be carried out when the scale buds and flower buds have been completely differentiated and garlic sprouts are exposed. At this point into the vigorous growth period, is the maximum efficiency of nitrogen fertilizer, so reminder fertilizer is a key top dressing, 25-30 kg per mu compound fertilizer.
Promote head fat. It is usually conducted 25 to 30 days after the fertigation application. Nitrogen fertilizer is mainly used in combination with phosphorus and potash fertilizer. It is advisable to apply 15-20 kg of high-nitrogen compound fertilizer per acre to meet the needs of nutrients when harvested and grown on garlic. .
Top dressing method
Generally used, with water or buried facilities. When topdressing organic fertilizers, they often go straight and open ditch, and apply chemical fertilizers. Fertilizers are generally applied by ditching and applying soil after application. After top dressing in seedling stage, we should pay attention to cultivating and weeding, keep soil loose and moisture, reduce the loss of nutrients, and speed up the absorption and utilization of nutrients by the root system.
