Spring management garlic fertilizer water
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.

Garlic salt solution has a good effect on preventing ricefield eel disease in spring.
After overwintering, ricefield eel begins to come out for activities after the temperature rises in spring. At this time, it is easy to die from diseases such as water mildew, skin rot, bacterial septicaemia and so on. If the clarifying solution of mixed leaching of 100 times fresh garlic and high quality salt is used in the feeding pond in time, it will be sprinkled once every 3 days for 2 times every 3 days, each time 2 kilograms per square meter of the feeding pond, and evenly sprinkled on the water, Monopterus Albus will not be infected with the above diseases. The survival rate of feeding is high.

Key points of garlic management technology in spring
First, after the management of the green period, after the garlic turns green, it should be watered and fertilized in time. The combination of watering and topdressing diammonium phosphate 20 kg per mu or ternary compound fertilizer 25 kg. Then carry on the shallow hoe to loosen the soil, raise the temperature and preserve the soil moisture. The yellow tip phenomenon appeared in the leaves before and after Ching Ming Festival, so the second topdressing should be carried out in time, and the watering times should be increased. Generally, it should be watered every 10 murals and 15 days to promote plant growth. II. Management of garlic bolting growth period at the beginning of May, garlic bolts began to differentiate. After the Beginning of Summer, garlic bolts entered a vigorous growth period, during which fertilizer pipes should be increased.
