Causes of root cracking of celery and its preventive measures

Celery is a kind of celery, its stem is strong, the root crack phenomenon often occurs in the process of planting, the root crack is actually a split stem, and most of them show that the base of the stem and petiole crack, this phenomenon will not only make the quality decline, but also cause bacteria to invade from the crack, resulting in root fertilizer. So what is the reason for the root cracking of celery? How to prevent it? Let's get to know it.

First, the reason for the cracking of celery.

The main results are as follows: 1. Under the condition of high temperature and drought, the growth and development of the plant is restrained. Under the condition of sudden high temperature and high humidity, the water-filled tissue expands and the root cracking occurs due to the strong water absorption capacity of the plant.

2. Like high temperature and drought, low temperature and drought will also inhibit the growth of celery and keratinize the epidermis. At this time, when there is high temperature, heavy rain or too much watering, it will make the stem tissue expand rapidly and cause the cutin epidermis to crack and cause the root to crack.

3. Celery needs a lot of boron in the growth process. If boron is deficient, it will lead to stem cracking, most of which will occur on the outer leaves, mainly in the inner part of the leaf epidermis. If the heart leaf is boron deficient during development, the medial tissue of the heart leaf turns brown and cracks occur.

II. Preventive measures

The main results are as follows: 1. in the seedling stage and time of celery seedlings, promote the development of petiole and root system, and water reasonably at the same time to avoid high humidity in the field. The seedlings should be dry and wet when they are 3-4 pieces, promote the development of roots, cultivate strong seedlings, and improve stress resistance and disease resistance.

2. timely planting should not focus on promoting root development after planting, so as to increase the ability of drought resistance and low temperature resistance of plants, so it is necessary to properly control water, strengthen mid-tillage and increase soil permeability in the early stage of planting, so as not to affect the growth and development of low temperature.

3. Strengthen field management, deeply plough the soil, increase the application of organic fertilizer, promote root development, enhance plant drought resistance, watering should not be too much after planting, but it is necessary to avoid cracking of the epidermis mainly on the inside of the leaves. In addition, if boron deficiency occurs during the development of the heart leaf, the medial tissue of the heart leaf turns brown and cracks occur.

4. Fertilization should be balanced, more organic fertilizer and farm manure should be applied to promote root growth and development, and topdressing should be applied in time in the middle of growth to avoid plant de-fertilizing or premature senescence. At the same time, ambient temperature and soil moisture should be controlled, foliar fertilizer and compound micro-fertilizer should be sprayed, especially boron fertilizer should be paid attention to to prevent physiological boron deficiency in celery.

The above is the introduction of the causes and preventive measures of celery cracking. I hope it can help you. If you want to know more about it, please follow us.
