How to manage garlic in the mid-to-late stages? 2011 production management recommendations for Midu County

At present, the garlic planted in Midu County has entered a period of rapid growth, and early-maturing varieties have entered the bolting stage. In view of the characteristics of garlic cultivation in Midu County and in light of this year's climatic conditions, we should focus on strengthening mid- and late-stage field management. Taking into account the characteristics of excessive rainfall at sowing time in September-October last year, soil compaction, and poor quality of spot sowing, and based on the county's conditions, we should apply fertilizer reasonably, carry out shallow tillage and weed control, and carry out timely pest and disease control focused mainly on leaf blight, so as to ensure a stable yield and bumper harvest of garlic this year.

1. Timely shallow tillage and weed control

As temperatures gradually rise, conditions are relatively favorable for weed growth in garlic fields, seriously affecting the normal growth of garlic. We should combine shallow tillage of garlic fields with timely weed removal to keep the soil loose and provide a good soil environment for the normal growth of garlic.

2. Reasonable fertilization

At present, most garlic plants have 6-8 leaves. In combination with flooding the garlic fields, topdressing should be carried out in a timely manner. Generally, it is appropriate to apply 25 kg of compound fertilizer and 8-10 kg of urea per mu. Because garlic has weak root regeneration ability and a relatively shallow root system, it is recommended to control the amount of fertilizer applied and increase the number of applications to ensure effective absorption of fertilizer by garlic.

3. Timely pest and disease control focused mainly on garlic leaf blight

Timely carrying out pest and disease control focused mainly on garlic leaf blight is the key point of current garlic field management. We should seize the best timing for control, effectively curb severe recurrence and spread of the disease, and ensure that garlic can bolt smoothly and the bulbs expand. In terms of pesticide use, propiconazole, Score (difenoconazole), and Junwei should be the main products, applied once every 5-7 days for 3-5 consecutive times. In terms of method, it is best to adopt unified and coordinated control, and quickly set off a peak of disease prevention in the county's main garlic production areas.

Regarding the problems existing in garlic production in Midu County in 2011, we must act actively and promptly, strengthen publicity and guidance, make the best use of the situation, and manage the mid- and late-stage management of garlic according to local conditions, especially pest and disease control focused mainly on garlic leaf blight, and deploy and implement it early. Scientific and technical personnel should go deep into the fields to guide garlic farmers well, quickly set off a peak of disease prevention, and lay a solid foundation for ensuring a high and stable yield of garlic in 2011.
