Lan Ye Jiao Jiao diagnosis and treatment
Lanye has a beautiful posture and not only has a high ornamental value, but also the luxuriant bodybuilding Lanye is a prerequisite for a good orchid. However, due to improper cultivation and management, it will cause a kind of physiological disease in the orchid leaf - the tip of the leaf tail coke, which affects the normal growth and ornamental value of the plant. The tail tip is a common symptom of orchids.
The reasons can be divided into the following categories:
1. Improper watering. The excessive wetness of the basin or the accumulation of water in the basin during the rainy season has caused the roots to become turbid and wet, causing the old seedlings to be sharpened. Control methods: timely watering in proper amount, sheltering rain and strengthening ventilation during the rainy season.
2. Improper watering time. When watering at noon in summer, the temperature difference between the water temperature and the potted soil is too large, which results in the obstruction of the normal physiological activity of the root system, weakening the absorption of water by the root system, and producing a physiological drought, which makes the blue leaf foliar. Control methods: Watering should be carried out in the morning and evening when the water temperature is close to the basin soil temperature in summer.
3. Summer heat, poor ventilation, basin soil temperature is too hot, Lange heat caused by Jiao Jiao. Control methods: Spray water to the surrounding environment, increase ventilation and shade density to cool down.
4. In early summer and autumn, when the winds are large and dry, the amount of water evaporation is large, and the air is too dry, causing new seedlings to be sharpened. Control methods: Spray water and spray on the foliage, pot surface and surrounding space in a timely manner to increase air humidity.
5. Improper fertilization. Over-concentration is too heavy to make the root system injured, the water backflow, causing the Jiao Jiao. Control methods: Immediately remove the pots and wash them with water. After drying, replace the pots.
6. Peat soil is mixed with fresh wood chips and other unfamed organic matter. After the bowls are watered, fresh wood chips and other unripe organic materials will generate heat during the process of fermentation and roasting, causing burning of the blue roots and causing a focal point. Control methods: Use full-combustion materials when preparing basin soil.
7. When the pot was turned over, the blighted root was not pruned and the plant material was not clean, which affected the growth and development of new roots and caused the new leaf coke tip. Control methods: Thoroughly remove the root rot and prepare 50% carbendazim for disinfection.
8. Fertilization is uneven. Potash fertilizer is an indispensable nutrient element for the growth and development of orchids, and is usually distributed in the most vigorous young shoots, young leaves, and root tips. When plants are severely deficient in potassium, the plants become shorter and the leaves are prone to scalding. Control methods: Add appropriate amount of ash leaching solution or potassium dihydrogen phosphate, etc. during fertilization. Once the blue leaf is damaged, it is not conducive to growth, so management must be strengthened during the cultivation process to prevent it.
