Cucumber leaf inlaid with gold edge is because of too much ammonium in the soil, hindering the cucumber caused by the absorption of calcium. First, the main symptoms of the blade edge was neatly gilded edge, the organization generally does not necrosis, the upper leaves suddenly become smaller, the growing point of contraction, in the greenhouse after the colonization of cucumber to harvest a period of time prone to appear. Second, the cause of the disease Similar to "parachute" shaped leaves, this is another form of calcium deficiency. 1, high soil concentration. In the stage of seedlings, management requires a moderate control of watering. Some vegetable farmers emphasize this point too much and delay watering. In this way, soil moisture is low, soil solution concentration is increased, and the absorption of calcium by plants is hindered, leading to calcium deficiency. 2. Strong acidity or no calcium fertilizer for many years. 3. The content of nitrogen, magnesium and potassium in the soil is too high, which inhibits the absorption of calcium by plants. 4, in the soil is alkaline conditions, the plant's absorption of boron is blocked will induce the absorption of calcium blocked, resulting in calcium deficiency. Third, control methods 1, this calcium deficiency symptoms, as long as the water, reduce the soil concentration, the new leaves will not appear Phnom Penh later. However, when the low ground temperature in winter affects the normal absorption of calcium in the roots, calcium deficiency symptoms may also occur. However, when the weather returns to normal and the temperature rises, the calcium deficiency symptoms will naturally disappear, but the Phnom Penh that has emerged will not disappear. 2. Apply appropriate amount of lime on sandy or acidic soils. Disclaimer: Some articles in this website have been transferred from the Internet.
