How to Grow Single-Clove Garlic? Detailed Explanation of Key Points in Single-Clove Garlic Cultivation Techniques

In recent years, single-clove garlic has become highly favored by consumers for its round, neat appearance and convenience in eating, and its market price is very good. However, in normal garlic cultivation, the goal is usually to minimize the occurrence of single-clove garlic, so it is difficult to produce high-quality, high-yield single-clove garlic. Vegetable expert Chang Wei explains that production practice has proven that late sowing is the main cause of single-clove garlic formation. In addition, early-maturing varieties, small cloves, poor soil, insufficient base fertilizer, drought and water shortage, severe weed infestation, excessive density, too few leaves, and failure to meet the temperature and light conditions required for clove bud differentiation can all lead to single-clove garlic formation. Therefore, these factors can be skillfully utilized to cultivate single-clove garlic.

Land Preparation and Bed Making

Choose sandy loam or light loam soil, and avoid continuous cropping. After the previous crop is harvested, apply 250 kg of decomposed barnyard manure and 50 kg of superphosphate per mu as base fertilizer. After shallow plowing and harrowing, make flat beds about 1.4 m wide.

Seed Garlic Selection

The seed cloves used for producing single-clove garlic must be small cloves, so they are generally selected from garlic varieties that have more cloves but smaller individual cloves. However, even among small-clove garlic, different varieties show significant differences in the percentage of single-clove garlic and single-clove weight, which affects the yield and quality of single-clove garlic. Therefore, before engaging in single-clove garlic production, variety comparison trials should be conducted to screen out varieties suitable for local planting with a high single-clove rate and relatively large single-clove weight. It is understood that early-maturing garlic varieties such as Ershuizao and Wenjiang Hongqixing garlic have a relatively high single-clove rate, reaching 76-92%.

The size of the seed cloves used for producing single-clove garlic is related to the yield and quality of single-clove garlic. Only by selecting suitably sized cloves as seed garlic can a high single-clove rate and moderately sized single-clove garlic be obtained. If the seed cloves are too large, small bulbs with 2-3 cloves will be produced, reducing the single-clove rate; if the seed cloves are too small, the single-clove garlic produced will be too small and lose commercial value. Generally, the single-clove weight of single-clove garlic is required to reach 5-8 grams. In order to produce single-clove garlic with a high single-clove rate and suitable size, trials on the relationship between seed clove size and single-clove rate and single-clove weight are needed. In general production, cloves weighing 0.5-1.5 grams or less are used as seed garlic.

Sowing and Production

The suitable sowing period for single-clove garlic must be determined through staged sowing trials in the local area. If sown too early, the garlic seedlings have a long vegetative growth period and accumulate more nutrients, making it easy to produce small bulbs with 2-3 cloves; if sown too late, the single-clove garlic will be too small. In autumn-sowing areas, sowing is generally delayed by about 50-80 days compared with garlic bulb cultivation. The seeding rate is generally about 100 kg per mu.

When sowing, first open furrows at a row spacing of 15 cm with a depth of about 6-8 cm, then sow at a plant spacing of 3-4 cm, and immediately cover with 3-4 cm of soil. After the entire bed is sown, evenly broadcast small radish seeds at a seeding rate of about 0.5 kg per mu, then rake the bed surface level and irrigate. The purpose of mixed sowing with small radish seeds is to use the characteristic of small radish germinating and emerging quickly to inhibit the growth of garlic seedlings, thereby increasing the single-clove rate.

Field Management

After the small radish emerges, thin the seedlings in stages, maintaining a distance of 6-8 cm. In the early spring of the following year, after all the small radishes are harvested and marketed, the garlic field should be managed with intertillage, weeding, topdressing, and irrigation. During the garlic bulb enlargement period, a sufficient water supply must be ensured.

Timely Harvesting

In autumn-sowing areas, harvest in a timely manner around the Beginning of Summer of the following year when the pseudostem becomes soft and most of the lower leaves have dried up. Generally, the yield is 300-500 kg per mu. After harvesting, dry in the sun for 2-3 days to prevent mold and rot.
