How to manage garlic in spring

How to manage garlic in spring? Please introduce the management of water and fertilizer after garlic turns green in spring, which is the key to the high yield of garlic. The weather turns warm, and the absorption of water and fertilizer increases gradually after turning green, especially in the pregnant bolting period and the expansion period of garlic, which is the peak period of water and fertilizer demand for garlic, so during the whole growth period of garlic, it is necessary to water and top fertilizer in time according to soil moisture and soil fertility. In particular, we should focus on watering "three water" and applying "three fertilizers". 1. Pour good water and fertilizer to return to green. In the Spring Equinox season, garlic seedlings begin to turn green and grow. Due to the low ground temperature in early spring, it is best to pour green water at noon to achieve the purpose of promoting early development of seedlings. Combined with watering, 15 kilograms of nitrogen, phosphorus and potassium compound fertilizer per mu or 15 kilograms of potassium sulfate are applied. After that, the water is properly controlled to promote root development and the differentiation of garlic bolts and heads. two。 Pour enough bolting water and re-apply bolting fertilizer. At the end of March and the beginning of April, flower buds and scale buds differentiated rapidly, and gradually entered the growth and progression stage of garlic bolts and garlic heads, the leaf area reached the maximum, and garlic bolts grew rapidly. The fertilizer and water management in this period directly affected the yield of garlic bolts and garlic heads. Furthermore, it needs more water, and it must be watered in time to meet the needs of its growth. therefore, 25 kg of compound fertilizer per mu is applied by combined watering, and 25 kg of nitrogen, phosphorus and potassium fertilizer is applied per mu after 15 days, or 15 kg of urea and phosphorus and potassium nitrate compound fertilizer each. Generally irrigating one water for 7-10 days, garlic bolting period, watering every 5-7 days, applying quick-acting nitrogen fertilizer every two days, and spraying foliar fertilizer to supplement some sulfur, garlic also has more demand for sulfur. 3. Pour enough inflated water and skillfully apply inflated fertilizer. The peak period of garlic expansion is after bolting, and the leaves and roots should be protected during bolting. At this time, the expansion and weight gain of garlic is the main, and the garlic leaves should be watered in time after bolting, so as to prevent the premature senescence of garlic leaves, prolong the green time of garlic leaves, and promote the transfer of nutrients to the bulb, mainly to increase material accumulation. Therefore, the topdressing is mainly based on available nitrogen fertilizer, supplemented by phosphorus and potassium, and 15kg urea or potassium sulfate compound fertilizer is applied per mu. Keep the soil moist to meet the water needs of garlic in the later stage, and stop watering about a week before harvest.
