Last Updated: 2024/11/05, Garlic green after the absorption of fertilizer and water gradually increased, especially in the germination period and garlic expansion period, is the peak of fertilizer and water, management should focus on watering "three", apply "three fertilizers". Pouring good return green water, applying good return green fertilizer spring ground temperature is low, it is best to irrigate return green water at noon, to achieve the purpose of promoting early seedling. Combined with watering, apply 15~25 kg of nitrogen, phosphorus and potassium compound fertilizer or 15 kg of potassium sulfate per mu, and then control water properly to promote root development. Garlic flower buds and scale buds quickly differentiated at the end of March and the beginning of April by watering enough bolting water and applying heavy bolting fertilizer

The amount of fertilizer and water absorbed by garlic increases gradually after turning green, especially in the period of pregnant bolting and garlic expansion, which is the peak period of fertilizer and water demand.

If the ground temperature is low in spring, it is best to pour the green water at noon to promote the early development of seedlings. Combined with watering, nitrogen, phosphorus and potassium compound fertilizer 15kg / mu or potassium sulfate 15kg / mu were applied, and then water was properly controlled to promote root development.

Watering enough bolting water and re-applying bolting fertilizer at the end of March and the beginning of April is the period of rapid differentiation of flower buds and scale buds of garlic, and gradually enters the growth and development stage of garlic bolts and garlic heads, the leaf area reaches the maximum, and garlic bolts grow rapidly, which requires more water in this period, so it must be watered in time to meet the growth needs. Combined watering, 25 kg compound fertilizer per mu, 25 kg nitrogen, phosphorus and potassium compound fertilizer per mu, or 15 kg urea and phosphorus potassium nitrate compound fertilizer per mu every 15 days. In general, water is watered every 7 to 10 days, water is watered every 5 to 7 days during bolting period, and available nitrogen fertilizer is applied every two times. At the same time, when foliar fertilizer was sprayed to supplement sulfur, garlic had more demand for sulfur.

After pouring enough swelling water and skillfully applying expansion fertilizer, garlic reached the peak stage of expansion after bolting, and the leaves and roots should be protected during bolting. Timely watering after bolting can prevent the premature senescence of garlic leaves and prolong the functional period of garlic leaves. After bolting, quick-acting nitrogen fertilizer was mainly applied, combined with phosphate fertilizer, and urea or potassium sulfate compound fertilizer was applied 15kg / mu. Keep the soil moist and stop watering the garlic a week before harvest.
