Garlic is our common seasoning vegetable. Its garlic has a multi-layered garlic skin. Generally, the garlic clove does not easily split the head. However, if the garlic leaves wrapped in garlic are reduced, the garlic cloves will crack the garlic skin when it is swollen, which will lead to the phenomenon of cracking of the garlic head. So what are the reasons for the garlic cracking? Let us take a look.

1, garlic varieties

There are many varieties of garlic. Some varieties have thinner outer skins, while garlic cloves are more fat. When harvesting or storing, they are prone to loosening.

2. The groundwater level in the garlic field is high and the soil is sticky.

Garlic is planted in a land with a high groundwater level and a soily weight. Due to poor drainage, the soil moisture is high, and the underground part of the sheath is prone to decay, resulting in a split head. It can be cultivated with sorghum or selected loam or sandy loam with low groundwater level. When mulching cultivation is carried out on the relaxed soil, the kneading surface should be gently photographed twice in the germination stage of the garlic cloves, and then the mulch film is covered to stabilize the growth of the seedlings, so as to prevent the garlic cloves from being exposed to the ground and the lobes are scattered.

3, improper sowing of garlic

When the garlic planting period is too early, the plant is prematurely degraded during the expansion period of the garlic, and the lower leaves are turned yellow. The leaf sheath around the garlic head is dried up early, and the leaf sheath is easily broken when the garlic is fat, causing the split head to spread. When the seeds are planted too late, the number of leaves during flower bud differentiation is small, and the leaf sheath is easily broken when the garlic is swollen. When the sowing period is appropriate, there are more leaves when the flower buds differentiate, which can better protect the garlic.

4. Improper management measures in the field

In the case of cultivating, irrigation, and improper dressing, it will cause cracks. After the autumn sowing garlic returns to green in early spring, it should be shallow tillage; the garlic should be stopped during the period of hypertrophy to avoid damage to the garlic skin. When the water is too much water or excessive rainfall or poor drainage in the first half of the harvest, the soil moisture is high and the ground temperature is high. The outer skin of the garlic is easily rotted, causing the split head to scatter.

Therefore, before harvesting, the irrigation should be properly controlled according to the soil moisture and weather conditions, and the drainage work should be done to reduce the soil moisture. During the growth of the plant, it is necessary to avoid the large-scale application of the rapid-acting nitrogen fertilizer to prevent the splitting of the head due to secondary growth. Plants that have undergone secondary growth should be harvested as early as possible, otherwise they will easily split the head.

5, garlic harvesting period and improper methods

Garlic breaks from the base when garlic is prematurely extracted from garlic or garlic, causing the garlic to be empty in the middle and easy to disperse. The garlic is harvested too late, and the outer skin of the garlic is small and thin, especially when the soil moisture is high, the outer skin is perishable, and the stem is easy to decay, causing the split head to scatter. In addition to mastering the maturity standard of garlic, the root should be cut off in time after harvesting. The root remaining on the stem is beige in the drying process, and it is firm and tight, and it has a protective effect on the stem and is not easy to disperse.

6, after the harvest, the rainy season

When the garlic is harvested and it cannot be dried after rain, if it is piled up indoors, the stem is prone to spoilage, causing scattered petals. When the amount is small, the garlic plants can be moved indoors, and the garlic is placed on the ground and dried. When the amount is too much, the garlic can be placed on the straw rack, covered with a banquet and a rainproof cloth, and the drainage ditch is dug around, and the air is immediately released after the rain stops.

7, improper storage of garlic

When the garlic is dried and moved to the interior, if it is too crowded and close to the ground, the garlic will return to the tide during the rainy season, and the stem will be moldy and rot, causing the split head to scatter.

The above is the cause of the garlic splitting flap. The garlic splitting head flap will seriously affect the sales of garlic and reduce the commerciality of garlic. In order not to affect the economic benefits, the farmers should pay attention to this problem. The right medicine to solve the problem of splitting the flap.
