1. Different varieties of garlic

The first choice for garlic is garlic varieties suitable for planting in this area. The garlic heads are large, the garlic cloves are fat, and each garlic clove has obvious separation, 4 to 8 pieces. The cloves constitute a head of garlic;

Single-headed garlic is a kind of garlic with small garlic heads and thin garlic cloves. After sowing, the seedlings grow weakly and have poor fertilizer absorption ability, which seriously affects the separation of the scale disk and easily forms a single-headed garlic.

2. Different sizes

Garlic is larger than single-headed garlic.

Extended information:

Compared with multi-clove garlic, single-clove garlic is smaller, which will seriously affect the yield of garlic, and the economic benefits of growing garlic will be greatly reduced. Therefore, during the planting process of garlic, people will try their best to take measures to prevent the occurrence of single-headed garlic.

Garlic likes cold weather and is more tolerant of low temperatures. It requires higher sunshine and high temperature to promote the differentiation of flower buds and scale buds.

In addition, sandy loam soil is the best place for garlic to grow. Garlic grown in sandy soil has a strong spicy taste, but its texture is loose and cannot be stored well. Garlic has shallow roots and many root hairs. The root system has weak ability to absorb water and fertilizer, so it is not drought-tolerant. In different growth periods, garlic has different requirements for soil moisture.

The germination stage requires higher soil moisture to promote root germination; the seedling stage should not have too much water to prevent the seedlings from growing too long and promote the longitudinal growth of the root system; the post-mother, scale bud and flower bud differentiation stages require higher requirements. During the bulb expansion period, the soil moisture should be reduced to prevent the bulb skin from rotting and turning black.

In order to avoid single-headed garlic, you should use high-quality garlic for seeding, fertilize the soil, strictly sow the date, plant reasonably densely, and strengthen management.
