Analysis of the Causes of Garlic Deformity and Control Measures

In recent years, as the garlic planting area has increased, the phenomenon of garlic deformity has become increasingly common. There are many types of garlic deformity, but their formation seriously affects the economic and edible value of garlic, and also has a certain impact on yield, causing many losses to farmers. So what causes abnormal garlic growth? How should it be prevented and controlled? Come to Qinong Web to see the detailed introduction.

1. Bread garlic

Bread garlic refers to garlic that, after harvest, has its scales exposed to sunlight and then begins to dehydrate into a membranous state; when pinched by hand it feels as soft as bread, hence the name bread garlic.

Causes: The occurrence of bread garlic is mainly due to the garlic seed. Improper selection of garlic seed, or improper storage conditions for the garlic seed, can cause it. Before sowing the garlic seed, the room temperature should be kept between 14-16 degrees, or it should be stored refrigerated at 0-5 degrees. If the storage room temperature is too low or the environment is too humid, the probability of bread garlic occurring will increase.

2. Single-clove garlic

Single-clove garlic, as the name implies, has a bulb with only one clove and no other divided cloves, so it is named single-clove garlic.

Causes: There are many causes. It can be produced from secondary bulbs; during growth the secondary bulb is small, thus forming single-clove garlic. It can also be caused by propagation from small cloves; during growth the clove is too small, thus forming single-clove garlic. In addition, improper water and fertilizer management during planting can also form single-clove garlic.

3. Multi-clove garlic

Multi-clove garlic refers to when the lateral buds of the bulb form cloves again after sprouting, and these newly formed cloves are relatively small, causing several garlic heads to appear on the bulb, resulting in low commercial value.

Causes: It is caused by low temperatures before overwintering. For example, if the garlic seed was subjected to low-temperature treatment before sowing, this situation will appear after growth and harvest the following year.

4. Loose-clove garlic

Loose-clove garlic is completely opposite to multi-clove garlic. It falls off before the bulb has grown and formed cloves, causing the cloves to scatter.

Causes: The main causes of loose-clove garlic are sowing too early and harvesting too late. Exceeding the optimal harvest time causes the bulb to rot in the soil, resulting in scattered cloves.

Control measures

Seed selection must be strictly standardized. Choose high-quality, well-colored, disease-free, undamaged cloves as garlic seed. Before sowing, the garlic seed should be sun-dried to avoid the occurrence of bread garlic. When sowing, the appropriate time must be grasped; it should not be too early or too late. Also, harvesting must be timely. When the leaves begin to wither and the pseudostem is soft but not brittle, this is the best time for harvest. During planting, management should be strengthened, and fertilizer and water regulation should be strictly controlled. Water and fertilize reasonably according to the growth condition of the garlic. Generally, water once each in December, February, and May, and the rest depending on the weather and soil; fertilize three times as well, combined with watering.
