What are the causes of garlic braiding and what preventive measures are there?
Garlic braiding refers to the phenomenon where, after the garlic bulb has formed, the garlic apical bud grows many slender clustered leaves under abnormal environmental conditions, resembling a horsetail, which is why it is called braiding or horsetail garlic. It causes the new leaves of garlic to be unable to grow normally, reduces photosynthesis in summer, and slows the development of garlic scapes, seriously affecting the yield and quality of garlic. So what causes garlic braiding? Let's take a look at the detailed introduction.
1. Improper selection of seed garlic
Garlic braiding is also called secondary growth. The main reason is the heredity and variety of the garlic seed. In some areas, the garlic seed is not pure and is not suitable for planting in the local environment, making secondary growth very likely to occur. In addition, the current poor quality of garlic seed can also lead to braiding later on.
Preventive measures: Select virus-free garlic seed according to local conditions. The garlic seed should be white in color, have plump apical buds, and be free of disease and damage. Garlic cloves with broken sprouts, rot, or yellowed stem plates should be eliminated in time.
2. Improper sowing time
Garlic cloves are formed from lateral buds in the leaf axils of the bulb, and they are affected by many factors such as temperature, light, and nutrients. If sowing is too early, it will cause flower bud differentiation and clove bud differentiation to advance. When low-temperature weather occurs in early spring, secondary growth will appear, resulting in braiding.
Preventive measures: The spring sowing time for garlic is generally around mid-March in spring, carried out when the daily average temperature is stable at 3-6 degrees, while the autumn sowing time is generally in September-October, carried out when the daily average temperature is 20-22 degrees. The specific sowing time should also be determined according to the local climate and variety, and blind sowing is not advisable.
3. Improper treatment of garlic seed
Before planting, garlic seed is usually treated to increase the emergence rate, but some farmers subject the garlic seed to cold or low-temperature treatment before sowing. This prolongs clove bud differentiation, resulting in secondary growth and causing braiding.
Preventive measures: Correct garlic seed treatment measures should be carried out. Before sowing, place the garlic seed in the sun to dry for 2-3 days to make the garlic cloves loose. When sowing, remove the residual stem plate from the garlic skin. This can reduce secondary growth in garlic and also promote early sprouting and uniform emergence.
4. Improper fertilizer and water management
If excessive nitrogen fertilizer is applied during fertilization, it will cause delayed dormancy of the garlic cloves, resulting in secondary growth. In addition, poor watering is also a cause of secondary growth in garlic. After clove bud differentiation, if too much water is applied or the watering amount is large, the probability of secondary growth in garlic will increase.
Preventive measures: Generally, garlic needs sufficient fertilizer and water throughout the entire growth stage, but it is not advisable to apply too much water and fertilizer at one time. During the seedling stage, the water requirement is low, so basically no watering is needed. During elongation, small amounts of water should be applied frequently, generally once every 7-10 days. During garlic bulbing, trace element water-soluble fertilizer can be sprayed at 5-10 kg per mu, which can promote garlic clove expansion and prevent or reduce braiding.
