Although garlic seedlings have nutrients in their growth stages, it is still appropriate to top-dress fertilizers in order to promote seedling growth and increase the plant nutrient area. Because the ability of the garlic root to absorb water and fertilizer is weak, the top dressing should be applied with quick-effect fertilizer so as to avoid the appearance of yellowing of the tip of the fertilizer. Garlic dressing usually 3 to 4 times, divided into:
1. Seedlings and fertilizer: Garlic out of Qimiao, apply 1 light human excrement to raise seedlings, avoid application of ammonium bicarbonate, to prevent burn seedlings.
2. Long-term fertilizer: After sowing for 60-80 days, reapply 1 compost of human-animal fertilizer plus chemical fertilizer, 20-30 tons per mu, 10 kg of ammonium sulfate, 5 kg of potassium sulfate or potassium chloride. Early-maturing varieties can be caught early, and late-maturing varieties can catch up, promoting vigorous growth of seedlings, thick stems and leaves, and less yellow tips or yellow tips when they are rotten.
3. Pregnancy and fertilizer: After planting garlic, the flower buds and scale buds gradually differentiate into the elongation period of the stem. In this period, the old roots were old and new roots occurred. At the same time, the stems and leaves and garlic sprouts were also rapidly elongating. The garlic also began to slowly expand. Therefore, more nutrients were needed and the available potassium and nitrogen fertilizers (comparatively compound fertilizers) should be reused for 10 to 15 kg. It was applied in the first half month of the end of the current period (the exudation seedlings were observed to have short stings on the lower part of the pseudo-stem) to meet the needs and to promote the fast and vigorous growth of the garlic bulbs.
4. Garlic inflated fertilizer: early maturing and early mid-maturing varieties, due to garlic when the temperature is not high; a correspondingly longer garlic expansion, in order to promote garlic hypertrophy, garlic must be applied before harvesting available nitrogen and potassium fertilizer. Such as: NPK composite fertilizer Mushi 5 to 10 kg, if the single application of urea, 5 kg can be, can not be applied too much, otherwise it will cause the formation of garlic buds turn green, and re-long leaves and consume garlic nutrients . Topdressing should be carried out before the garlic pods are harvested. When the garlic pods are harvested, they are rich in nutrients and promote the expansion of garlic heads. If topdressing is carried out after harvesting the garlic pods, it will easily lead to a reduction in greediness. If the soil is fatter and the garlic leaves are thicker and darker, you may not apply large-scale fertilizers. The late-maturing varieties have a high temperature due to convulsions, and they usually receive garlic after 20 to 25 days after harvesting, so they can also avoid large-scale fertilizers.
