Symptoms of magnesium deficiency in eggplant:
Magnesium deficiency in eggplant generally causes the lower leaves to fade and turn yellow, while the veins remain green, and sometimes the leaves are also accompanied by orange-yellow, purplish-red and other mixed colors. The difference from potassium deficiency is that magnesium deficiency chlorosis tends toward yellow-white or white; the difference from physiologically aged leaves is that with magnesium deficiency the veins do not fade, and the diseased leaves stay fresh and alive for a longer time, whereas physiologically aged leaves usually turn yellow evenly, with veins and leaf mesophyll fading at the same time, and mostly appear withered and lacking a fresh look. Because more magnesium is needed when forming fruit, magnesium deficiency often appears in the middle and late stages of growth, and often first appears on several leaves near the fruit.
Prevention and treatment methods for magnesium deficiency in eggplant:
Prevention and treatment method one,When eggplants are grown in succession in greenhouses, avoid continuous cropping with vegetables that have a high magnesium requirement, such as cucumber and tomato.
Prevention and treatment method two,Irrigate in time, keep the soil moist, and prevent the soil salt concentration from becoming too high, which would inhibit magnesium uptake.
Prevention and treatment method three,Apply magnesium fertilizers such as magnesium sulfate at about 10-20 kg per mu. For some acidic soils, magnesium lime is best, at about 50-100 kg per mu.
Prevention and treatment method four,Spray with a 1%-2% magnesium sulfate solution, once every 5-7 days, for a total of 3-5 sprays.
