Garlic spring management technology and what medicine to play in spring?

Management techniques of garlic in spring;

1. Generally, garlic turns green after electric shock. At this time, it is necessary to water and topdressing in time, and topdressing 20 kilograms of diammonium phosphate or 25 kilograms of compound fertilizer can be combined with water per mu, and then hoeing and loosening the soil to improve the temperature and moisture. Before and after Tomb-Sweeping Day, garlic leaves will turn yellow, so it is very important to apply fertilizer for the second time and increase the watering times, generally once every 20 days to promote plant growth.

At the beginning of February and May, garlic seedlings will begin to differentiate. After summer, young garlic shoots will enter a vigorous growth period, so fertilizer management must be strengthened. Fertilizer should be applied before the leaves germinate, and 25 kilograms of compound fertilizer should be applied per mu. After the young garlic shoots come out of leaves, they should be watered continuously to promote germination, and the time from mango seeds to the bending of young garlic shoots before and after can improve the emergence rate of young garlic shoots.

3. Once the buds are harvested, the garlic cloves will begin to swell and need more water, so it is very important to water them in time to keep the soil moist and prevent premature decay. Water must be stopped one week before garlic harvest to prevent excessive soil moisture, garlic cloves from rotting and garlic from loosening.

What medicine do you use?

1. Garlic is easy to induce pests after spring. Common pests include onion thrips and garlic maggots. For onion thrips, chemicals such as cypermethrin or octreotide can be used to control them. If there are garlic maggots, trichlorfon powder or abamectin can be used to control them. After being diluted with water, it can be sprayed 1 time, 3-4 times continuously.

2. After spring, if plants are not properly maintained, it is easy to get sick. Common diseases are rust, white rot and leaf blight. Rust can be sprayed with antirust agent, and white rot and leaf blight can be controlled by carbendazim or chlorothalonil. After dilution, spray it once a week 1 time, and spray it continuously for 3 times.

In addition to pests and diseases, chemical agents should be used to weed garlic in the spring. When the temperature is suitable in spring, weeds will compete for nutrients and water in garlic, which is not conducive to plant growth. After spring, garlic can be sprayed with garlic weeding net or herbicide. Within 1-2 months after the emergence of garlic seedlings, the pesticide was diluted with water and sprayed on weeds.
