First, the heartburn 1. Symptoms: The leaf veins of the heart begin to turn brown, and the cells of the leaf margin become necrotic and dark brown. It rarely occurs in the early stages of fertility, but begins when 11 to 12 true leaves occur. 2. Occurrence conditions and causes: Heartburn occurs easily under conditions of high temperature, drought, and excessive fertilization. High temperature can accelerate the growth rate and promote the excessive absorption of nitrogen, potassium, magnesium and other elements of plants, which will affect the absorption of calcium. The heartburn is caused by calcium deficiency. Under drought conditions, due to the weakening of the absorption capacity of calcium in the root system, it is easy to cause calcium deficiency in the plant, and the more acid soil, the heavier it will be. 3. Control methods: First of all, to avoid high temperature and drought, appropriate temperature and humidity management; can be applied to acid soil quicklime to adjust to neutral or near neutral; application of nitrogen, potassium, magnesium and other fertilizers to the right amount. In the event of heartburn symptoms, a 0.5% calcium fluoride or calcium nitrate solution can be sprayed on the foliage.
Second, the hollow 1. Symptoms: hollow is a physiological aging phenomenon, the site of occurrence is the petiole, is the petiole marrow site and the transmission of tissue aging cells, cell fluid glial loss of vitality and cell membrane gap. Mostly extending from the base of the petiole, the outer leaf precedes the inner leaf on the same plant, and occurs earlier from the leaf base to the first node. The hollow part of the petiole is white flocculous and the corky tissue grows. 2. Occurrence conditions and reasons: Hollow occurs in the sand with large soil, the progress is fast, fertilizer points are insufficient or late defertilization also occurs, the product is too cooked or long water loss, excessive spraying of gibberellin, etc. Soil drought or temperature is too high, too low, cold celery is also prone to occur. 3. Control methods: Avoid excessive cultivation of sand on the soil, in addition to the application of base fertilizer, in the growth and development process should be timely fertilizer, such as the discovery of leaf color turn thick deferring phenomenon, can be used 0.1% urea liquid fertilizer Root dressing outside.
Third, petiole cracking 1. Symptoms: The majority of the performance of the base of the stem together with the petiole cracking at the same time, not only affect the quality of goods, but the bacteria can easily infect, resulting in mild rot of the celery. 2. Occurrence conditions and reasons: mostly at low temperature, drought and dryness: due to severe suppression of fertility. In addition, under conditions of sudden high temperature and high humidity, due to the excessive water absorption capacity of the plants, it can also occur when the tissue is filled with water. 3. Preventive measures: normal temperature and humidity management, especially in the greenhouse production of celery, we must strengthen the insulation measures; deep plowing the soil, apply more organic fertilizer, promote the normal growth and development of roots, and enhance its drought resistance and low temperature resistance.
Fourth, boron deficiency syndrome 1. Symptoms: It is characterized by abnormal petiole hypertrophy, shortening, and medial to the medial, curved part of the medial organization becomes brown, gradually cracked, petiole twisted so chapped. The development sequence is: gradually browning from the edge of young leaves inward, and finally the heart leaves are necrotic. 2. Occurrence conditions and reasons: First, due to the lack of boron in the soil, and second, there are many other nutrients in the soil, which inhibits the normal absorption of boron. In addition, boron deficiency is also prone to occur under conditions of high temperature and drought. 3. Control methods: If there is a lack of boron in the soil, 1 kg of borax can be applied per acre to supplement the deficiency of boron; after the symptoms of boron deficiency are found during the growth period, a 0.1% to 0.3% borax aqueous solution can be used for foliar spray.
