The Latest Causes of Garlic Secondary Growth and How to Prevent It
Garlic is an essential vegetable in our daily lives. As demand for it grows, its planting area is gradually expanding. However, improper planting and management practices can cause garlic to undergo secondary growth. Secondary growth leads to deformed garlic and disorderly arrangement of the cloves, seriously affecting quality and yield. So what causes garlic secondary growth? How can it be prevented? Let's take a look together.
I. Causes of Secondary Growth
1. Improper selection of garlic varieties for planting. The genetic characteristics of the seed garlic are the main factor in garlic secondary growth. When selecting seed garlic, you must first consider the local growing environment and choose a garlic variety suited to local conditions. The seed garlic selected should have large bulbs, plump cloves and obvious separation. If you do not choose a variety suited to local growing conditions, secondary growth is very likely to occur.
2. Improper storage of garlic seed. One month before sowing, if the seed garlic is stored at a temperature below 16 degrees and an air humidity above 75%, the low-temperature, high-humidity environment will increase the secondary growth rate of the seed garlic.
3. Improper treatment of garlic seed. Farmers in many regions treat the seed before planting garlic. If low-temperature treatment is used on the seed, the garlic will sprout earlier after sowing, and secondary growth is very likely to occur.
4. Improper sowing time. Garlic has strict requirements for temperature, light and nutrients. If the sowing time is improper, it will affect bulb growth and cause secondary growth.
5. Improper selection of garlic cloves. Some people believe that when selecting seed garlic for planting, the larger the clove, the better, as it benefits the seed garlic. But this is incorrect. The size of the seed garlic cloves must fall within a certain range. If too small, single-clove garlic is easily formed; if too large, secondary growth is easily caused.
6. Cultivation and management measures. Although garlic has strong adaptability, it is quite sensitive to the growing environment, nutrients and water. During management, if nitrogen fertilizer is applied excessively or too much fertilizer and water are given, secondary growth will occur.
II. Prevention Methods
When selecting varieties, be sure to take the local environment into account and choose a variety suited to local planting. When storing seed garlic, be sure to choose an environment with a temperature above 20 degrees and an air humidity below 75%. When treating seed garlic, low-temperature treatment methods should not be used. Choose garlic cloves of an appropriate size, neither too large nor too small. The sowing time must be well controlled, neither too early nor too late. In addition, plant at a reasonable density.
