After spring, the weather became warmer, garlic seedlings turned green, roots began to grow adventitious roots, garlic sprouts, garlic differentiation, then ensure seedlings robust growth, accumulation of garlic sprouts, garlic and more accumulation of nutrients, is to seize the key to high quality and high yield of garlic. Continuous cultivation of garlic in major producing areas leaves relatively scarce trace elements in the soil, such as iron, copper, manganese, zinc, magnesium, molybdenum, boron, cobalt, and calcium. The lack of trace elements leads directly to the lack of robustness and poor growth of garlic plants, which can seriously invade fungi and bacteria and cause various diseases, resulting in reduced yields. This period of management needs to strengthen fertilizer and water management and pest and disease control.

Fertilizer management 1. After garlic returns green, it must be timely watered and fertilized. In combination with water, 20 kg of diammonium phosphate per acre, or 25 kg of ternary compound fertilizer. Before and after the Ching Ming Festival leaves appear yellow tip phenomenon, we must promptly chase the second fertilizer, and increase the number of watering, generally every 10-15 days, pouring water, to promote plant growth.
At the beginning of 2.5 months, garlic sprouts began to differentiate. After the beginning of summer, garlic sprouts entered a vigorous growth period. During this period, fertilizer and water management should be increased. When the garlic sprouts did not extend the leaves, they should chase the third fertilizer and apply 25 kg of compound fertilizer. After the garlic sprout sticks out of the leaf mouth, it is necessary to continuously water the water and promote it with water. After garlic cloves began to differentiate, the area of ​​garlic leaves expanded, and the demand for fertilizer and water increased. The water should be poured once every 7 days, combined with watering, 10 to 15 kg of urea, 10 kg of ternary compound fertilizer, and 200 times of the compound fertilizer. The potassium dihydrogen phosphate solution was applied 2-3 times. Watering should be stopped 3-4 days before convulsions so as to avoid brittleness and tenderness.
Diseases and Insect Pests Garlic pests are mainly garlic sprouts; diseases include leaf blight, purple spot, and viral diseases.
1. Insect pests. Garlic sprouts can be used 2% abamectin 800-1000 times, sprayed every 5-7 days, sprayed 2-3 times in a row; can also use phoxim irritation.
2. Diseases. Leaf blight can be controlled by carbendazim glue suspension, 50% acetaminophen WP or 50% ceric chloride copper wettable powder spray, spraying once every 7-10 days, and continuous control 3-4 times.
In the early stages of the onset of purple spot, spray 75% chlorothalonil wettable powder 500-600 times liquid, 64% antivirus WP 500 times, 58% metalaxyl MnZn wettable powder 500 times or 50% acetaminophen Wet powder 1500 times liquid, alternating once every 7-10 days, continuous control 3-4 times.
Virus disease: 1.5% phytopathogenic Ling 2 emulsion 1500 times, 20% virus A WP 500 times, 0.5% antitoxic agent No. 1 300 times or 5% bacteriocin clear 300 times, spray 10 days Once, spray 2-3 times.
