What are the precautions during the bolting stage of garlic?
The bolting stage of garlic is a critical period for increasing garlic yield. At this time, the garlic has finished growing, and the next step is the growth period of the garlic scapes and bulbs. Management during this period is extremely important. However, some issues also need attention to avoid causing premature plant decline. Let's take a look at the introduction to precautions during garlic bolting below.
1. Water and fertilizer management
After garlic enters the bolting stage, its vegetative body grows rapidly, all leaves have emerged, the leaf area reaches its maximum, the garlic scapes begin to emerge, and the bulbs begin to develop. During this period, yellowing leaves and dry tips are very likely to occur, so attention should be paid to fertilizer and water management, using heavy water and heavy fertilizer to promote plant growth so that the pseudostem grows evenly thick from top to bottom. If there is a lack of water and fertilizer during this period, or if fertilizer and water are not supplied in time, it will hinder the normal growth of the plant, causing the pseudostem and bulb to grow unevenly from top to bottom, and making harvest difficult and prone to breaking.
2. Stop watering before harvest
About one week before harvesting the garlic scapes, watering should be stopped, and at the same time, shallow hoeing should be done to loosen the soil, so that the plant lacks water and shows wilting, in order to prevent the stem nodes from loosening, which is beneficial for the scapes. Autumn-sown garlic bolts 7-10 days earlier than spring-sown garlic, which can greatly increase yield and boost returns.
3. Foliar fertilizer spraying
In garlic management, foliar fertilizer spraying should be strengthened to prevent the plant leaves from yellowing and drying at the tips, which can lead to premature plant decline and reduced yield. Amino acid foliar fertilizer can be sprayed. At the same time, spraying borax solution and urea solution can not only supplement the plant's trace elements, but also improve the plant's disease resistance, increasing both yield and quality.
4. Pest and disease control
When garlic enters the bolting stage, as temperatures rise, its pests and diseases also reach a peak period. The main diseases include purple blotch, leaf blight, and late blight. The main pests include thrips and garlic maggots. For diseases, fungicides such as dimethomorph-mancozeb, mancozeb, and Antaisheng can be used for control; for pests, chlorpyrifos EC can be sprayed for control, or chlorpyrifos EC can be used for root drenching.
