What harm do strawberry nutrient deficiency symptoms cause? A detailed explanation of the latest preventive measures

During the growth period of strawberries, various nutrient elements are needed, and a deficiency of certain elements can lead to corresponding diseases, and this kind of physiological disease caused by the lack of a certain nutrient element is called a deficiency symptom. Below, let us learn about the symptoms and preventive measures of strawberry nutrient deficiency.

1. Calcium deficiency

Strawberry calcium deficiency is mostly a concern during the flowering and budding stage. The tips and edges of new leaves turn brown and appear scorched or dry up, the leaf veins become chlorotic and brittle, and after the leaflets unfold they cannot grow properly. The root system is short and underdeveloped, and hard fruit is very likely to occur.

Preventive measures: Water at the right time to keep the soil moist. When calcium deficiency is found, spray the leaves with 0.2-0.3% calcium chloride or 0.3-0.5% calcium nitrate solution; in cases of severe calcium deficiency, apply 2 kg of 47% biochemical calcium fulvic acid per mu and flush it along the furrows when watering.

2. Magnesium deficiency

With strawberry magnesium deficiency, the edges of the upper leaves first turn yellow or brown and scorched, then the areas between the veins become chlorotic and dark red spots appear, and some spots may become necrotic spots. When scorching is severe, the leaves on the stems appear light green, and the scorching phenomenon develops as leaf age increases and magnesium deficiency worsens. Generally, magnesium deficiency is very likely to occur when strawberries are grown on sandy low-fertility soil or when nitrogen fertilizer and potassium fertilizer are applied excessively.

Preventive measures: Fertilize in a balanced way and prevent excessive use of nitrogen fertilizer and potassium fertilizer. When magnesium deficiency is found, promptly spray the leaves with a low concentration of magnesium sulfate, generally once every 10 days or so, for 2-3 consecutive times.

3. Iron deficiency

With strawberry iron deficiency, young leaves turn yellow and lose green. At first the leaf veins remain green, while the areas between the veins turn yellow-white. In severe cases, the new leaves that grow out turn white, and the leaf edges become necrotic or the leaflets turn yellow.

Preventive measures: Apply more organic fertilizer. Drain water promptly and keep the soil moist. When iron deficiency is found, promptly spray the leaves with a low concentration of ferrous sulfate.

4. Boron deficiency

With strawberry boron deficiency, the leaves become shortened and ring-shaped, deformed, and wrinkled. The leaf edges turn brown, the leaf vein tips of old leaves lose green, and the leaves curl upward. Runners develop more slowly, there are few roots, the pollination and fruit-setting rate is low, the fruit is deformed or tumor-shaped, the fruit seeds are small, and fruit quality is poor.

Preventive measures: Water at the right time to keep the soil moist. When boron deficiency is found, promptly spray a borax solution leaf fertilizer.

5. Copper deficiency and zinc deficiency

When strawberries are deficient in copper, the areas between the veins of new leaves lose green and white spots appear; when deficient in zinc, old leaves become narrower, especially the basal leaves. The more severe the zinc deficiency, the more the narrow-leaf portions elongate. When zinc deficiency is severe, new leaves turn yellow, the leaf veins are slightly red, and the leaf edges have obvious serrated margins.

Preventive measures: When copper deficiency is found, spray the leaves with 0.1-0.2% copper sulfate solution, generally once every 5-7 days, for 2-3 consecutive sprays. When zinc deficiency is found, promptly spray the leaves with 0.05-0.1% zinc sulfate solution.
