What Causes Cracked Roots in Celery? Causes and Prevention Measures

Celery is a type of celery, and its stalks are thick and sturdy. During cultivation, cracked roots often occur. Cracked roots are actually cracked stalks, mostly showing as the base of the stalk splitting open together with the leaf stalks. This phenomenon not only reduces quality, but also allows pathogens to invade through the cracks, causing root fertilizer. So what causes cracked roots in celery? How should it be prevented? Let's learn about it together.

1. Causes of Cracked Roots in Celery

1. Under high-temperature and drought conditions, the growth and development of the plant are inhibited. Under sudden high-temperature and high-humidity conditions, because the plant's water absorption capacity is too strong, the tissues become filled with water and expand, causing cracked roots.

2. Just like high temperature and drought, low temperature and drought can also inhibit celery growth and cause cutinization of the epidermis. If high temperature, heavy rain, or excessive watering then occurs, the stalk tissues expand rapidly, causing the cutinized epidermis to split and resulting in cracked roots.

3. During the growth of celery, a large amount of boron is needed. If boron is deficient, the stalks will split, mostly on the outer leaves, mainly as splitting of part of the epidermis on the inner side of the leaf. If boron is deficient during the development of the heart leaves, the inner tissues of the heart leaves turn brown and develop cracks.

2. Prevention Measures

1. During the seedling stage of celery, thin the seedlings in time to promote thick leaf stalks and root development. At the same time, water reasonably to avoid excessive field humidity. When the seedlings have 3-4 leaves, keep the soil alternately dry and wet to promote root development, cultivate strong seedlings, and improve stress resistance and disease resistance.

2. Transplant at the right time. After transplanting, focus on promoting root development to increase the plant's drought resistance and low-temperature resistance. Therefore, in the early stage after transplanting, control water appropriately, strengthen intertillage, and increase soil permeability to avoid low temperature affecting its growth and development.

3. Strengthen field management, deep plow the soil, and apply more organic fertilizer to promote root development and enhance the plant's drought resistance. After transplanting, watering should not be excessive, but it is necessary to avoid mainly splitting of part of the epidermis on the inner side of the leaf. In addition, if boron is deficient during the development of the heart leaves, the inner tissues of the heart leaves turn brown and develop cracks.

4. Fertilization should be balanced. Apply more organic fertilizer and farmyard manure to promote root growth and development. In the middle growth stage, topdress in time to avoid nutrient deficiency or premature aging of the plant. At the same time, control the environmental temperature and soil moisture, spray foliar fertilizer and compound micronutrient fertilizer, and especially pay attention to the application of boron fertilizer to prevent physiological boron deficiency in celery.
