The Causes and Prevention of Cycad Yellow

The cycads, also known as Tieshu, are evergreen woody plants. The ancient shape of the tree, the main trunk is thick, hard like iron, Ye Rui like a needle, long life, is a large foliage plant. In the cultivation of cycads, there are often yellow leaves and dead-tip cokes. The causes and prevention are as follows: Iron deficiency. Potassium soluble iron is limited and yellow, can be sprayed every 2-3 weeks 0.2% of ferrous sulfate or 0.5% of ferric sulfate when applied. Ferrous sulfate contains iron, sulfur and other trace elements, not only can prevent the yellow leaves of cycads, promote bright green leaves, and can also stimulate plant growth. Frozen. Su Tiexi is chilly and cold. When the temperature is lower than 0°C, it is subject to freezing injury. The flesh roots in winter are extremely prone to freezing, resulting in yellowing of the leaves and even the death of the whole plant. Therefore, winter maintenance should pay attention to freezing and keeping warm, so that the winter temperature is not lower than 5 °C, so you can prevent the leaves from freezing. Insufficient or excessive light. Cycad is a positive tree species, but in the continuous exposure to intense sun and hot sun, the leaves are easily burned and cause dry tip yellowing, especially when the new leaves have not been stretched, they should pay attention to proper shade. Although the cycad is resistant to half-shade, but placed in a dark place for a long time, lack of sunlight will also make the leaves become green and not strong. Therefore, in the spring, autumn and winter seasons, the cycad should be placed in a sunny place, and in the summer, it should be placed under a shade shed to avoid strong light irradiation, to promote the sprouting of branches and leaves, to grow robustly, and to have green leaves. Pendulum soil is not uniform. The iron roots of cycads are resistant to moderate drought but are not resistant to leeches. Pendulum soil can be dry. For example, if watering is too much, the soil voids are full of water, and the roots' respiration is weakened, which affects the absorption of water and inorganic salts, causing the leaves to begin to wilt from bottom to top. In severe cases, the roots become dark and the plants die. However, the basin soil is too dry, and due to the lack of moisture necessary for growth, the leaves become yellowish. The principle of watering is "do not do not pour, pouring is poured", especially in winter, if the basin soil is not dry, do not have to water. Humidity is not enough. Su Tiexi warm and humid environment. Winter shed indoor warming, low air humidity, often appear dull leaf color, leaves withered coke or dry blade tips, so often to take leaf spray, ground water spray or aerial spray, increase air humidity, this can Prevent blade tips from being too low due to humidity. Soil sticky. Su Tiexi has a well-drained, loose fertile sandy loam and avoids use of poorly drained clay soils, which would otherwise lead to rot and yellowing and even death due to lack of oxygen. The potted soil can be mixed with 6 parts of garden soil, 3 parts of rot leafy soil and 1 part of eucalyptus ash, 4 parts of humus, 3 parts of mature feces and cake fertilizer, 3 parts of sand or sawdust, and a small amount. Iron powder and bone meal are used after preparation. Turn over prematurely. Su Tie Shang was prematurely turned to change soil during the dormant period, and it was prone to frost damage, resulting in dehydration of the leaves. Therefore, it is best to end dormancy in the spring, sprouting or growth has already begun, changing soil is safer. The yellow leaves that have appeared can be cut off. As the temperature rises, the plants will regenerate new leaves. Pest damage. Cycad is vulnerable to scale insects in poorly ventilated environments and yellow leaves are damaged. Therefore, in addition to enhanced ventilation, insects can also be sterilized with 40% dimethoate 1000 times or 2.5% deltamethrin 2500 times during the nymph hatching period. In addition, leaf blight is likely to occur in high temperatures and rainy seasons or in severe cold, causing leaf segments to die. Therefore, in addition to cutting sick leaves when curing, but also to do warm work in the winter, spraying a 5% carbendazim 500 times in high temperature and rainy season to prevent. In short, regardless of the cause of the yellowing of the leaves, it is difficult to turn green, so the conservation measures should be earlier.
