Prevention and treatment methods for rose nutrient deficiency symptoms
Do you know these? Small knowledge about roses from the Flower Clinic, prevention and treatment methods for rose nutrient deficiency symptoms. Next, the site editor will introduce to the netizens.
Symptoms
One, nitrogen deficiency causes leaves to turn light green.
Two, potassium deficiency first appears in the tips of old leaves or lower leaves with yellowing, then the yellowing spreads to the center of the leaf, and in severe cases, it extends to the base, causing the leaves to curl and deform.
Three, iron deficiency often starts in new leaves of young branches, with veins remaining green, the space between veins turning yellow, and in later stages, a green network pattern can be seen on yellow leaves. In severe cases, except for the green veins, the rest turns yellowish white.
Four, magnesium deficiency initially causes irregular yellow streaks on both sides of the leaf margins, which then merge into a yellow band on both sides of the midrib, with the main vein and base maintaining a triangular green area or the entire leaf turning yellowish brown, leading to leaf fall and branch withering.
Etiology
One, nitrogen deficiency in the soil or basic fertilizer.
Two, in sandy soil with less organic matter, potassium is easily washed away after rain, and in addition, excessive application of ammonium nitrogen in the soil can prevent the roots from absorbing potassium, leading to potassium deficiency symptoms.
Three, in alkaline soil with high content of carbonates or calcium carbonate, iron is easily fixed, causing iron deficiency symptoms.
Four, in acidic soil, old leaves are prone to magnesium deficiency.
Prevention and Treatment Methods
(1) It is recommended to apply Baode biological fertilizer or compost made from enzyme bacteria.
(2) When there is a severe potassium deficiency, apply a small amount of potassium sulfate in winter or spring; for mild potassium deficiency, spray 0.5% potassium sulfate solution on the leaves 2-3 times.
(3) When roses are deficient in iron, use the high-pressure injection method to inject CH-01 concentrated fruit yellowing injection, which shows immediate effects, and generally one injection can last for 4-5 years.
(4) When there is magnesium deficiency, spraying 0.5% magnesium sulfate solution is effective.
