Causes of garlic Hollow and Preventive measures

Garlic is one of the common condiments in our life, which is planted all over the country, but many farmers report that the phenomenon of garlic hollowness is becoming more and more serious. From the outside, the garlic is full, but after the sun, the dysplastic scale buds are dehydrated to form a film, which will shrink when pinched with the hand. It seriously affects the commodity value of garlic. What causes it? How to prevent it? Let's get to know it.

The reason for the hollowness of garlic

1. Species degeneration

Garlic belongs to asexual reproduction and generally does not break up and change its characters. Most growers keep their own seeds, but in some areas they do not replace garlic seeds for a long time, which will lead to serious degradation of garlic species and poor disease resistance and stress resistance. resulting in the phenomenon of hollow.

2. Lack of nutrients

Garlic needs sufficient fertilizer and water during the decomposition period of scale buds. If there is insufficient fertilizer and water, and the planting density is too high, coupled with the poor soil fertility, the garlic scale buds will not be able to decompose and increase the probability of hollow.

3. Improper planting time

Garlic for planting time is relatively strict, planting time too early or too late will cause hollow garlic formation, planting too early temperature is too high, not conducive to scale bud decomposition, planting too late temperature is too low, prone to dead trees or premature senescence.

4. Excessive application of nitrogen fertilizer

Many growers will apply a lot of nitrogen fertilizer when the garlic turns green, and the early application of nitrogen fertilizer will promote the growth of garlic, but excessive application of nitrogen fertilizer will cause the vigorous growth and secondary growth of garlic, and the vegetative growth of garlic is stronger than reproductive growth, so it is easy to appear hollow phenomenon.

II. Preventive measures

Garlic is recommended to rotate for 2-3 years instead of continuous cropping, which will increase the incidence of diseases such as garlic maggots. When planting, we should grasp the planting time, plant reasonably according to the local weather, control the application rate of nitrogen fertilizer when watering green fertilizer and water, and increase the application of phosphorus and potassium fertilizer during the decomposition period of scale buds to promote the decomposition of scale buds. In the later stage of growth, foliar fertilizer and spraying some boron fertilizer and amino acids can significantly improve plant stress resistance, promote early maturity, prevent lodging and premature senescence, and increase yield obviously.
