Solutions for Cucumber Calcium, Magnesium, Boron, Zinc and Iron Deficiency

Everyone loves to eat cucumbers, and many people even grow them in their own vegetable gardens, but most people basically encounter the phenomenon of poor growth of cucumbers in the process of growing cucumbers. One of the major reasons is that the supplement of trace elements is not in place. For example, the lack of calcium, magnesium, boron and other trace elements in cucumbers are essential nutrients in the growth process of cucumbers. So how can cucumbers lack these elements? Let's learn together.

1. Cucumber lacks calcium

Symptoms: When calcium deficiency, cucumbers are mainly characterized by dwarfing of plants, short internodes, most obvious near the top, upper leaves are small, the edges of the leaves are dead, and the shape of the leaves is mushroom-like or parachute-like, and gradually withers from the edge inward.

Solution: Pay attention to the application of calcium fertilizer when changing crops, and mix lime fertilizer, calcium nitrate, superphosphate, etc. into the fully decomposed organic fertilizer. In addition, excessive application of potassium and nitrogen fertilizers during the planting process will also inhibit the absorption of calcium by the plants, so try to avoid them. When the cucumber has calcium deficiency symptoms, it can be solved by spraying 0.3% calcium chloride solution on the leaves 3 to 4 times, or by spraying calcium fertilizers such as chelated calcium.

2. Cucumber lacks magnesium

Symptoms: When cucumber lacks magnesium, the mesophyll between the veins of the lower leaves of the plant gradually chlorosis, the veins remain green, forming a clear network of flowers and leaves, and the leaves become hard.

Solution: Apply calcium magnesium phosphate fertilizer, magnesium carbonate and other magnesium-containing fertilizers when applying basal fertilizer. At the same time, excessive application of nitrogen fertilizer should be avoided. When there is a lack of fertilizer, you can spray 1% to 2% magnesium sulfate and chelated magnesium solution 2 to 3 times on the leaf surface. In addition, potassium fertilizer and zinc fertilizer should be added while supplementing magnesium.

3. Cucumber lacks boron

Symptoms: When cucumber is deficient in boron, the growth point of the plant is necrotic and the flower organs are not fully developed. The internodes near the growth point were significantly shortened, the leaf margins showed yellowing edges, and the leaf margins were yellowing toward the depth, showing a wide band of leaf margins and atrophy of leaf veins.

Solution: Add 1.5 to 2 kg of borax when applying base fertilizer to prevent boron deficiency in plants. Formula fertilization technology can also be used to keep the soil moist and not to apply too much lime. When symptoms of boron deficiency occur, foliar sprays of chelated boron can be used to solve them.

4. Cucumber lacks zinc and iron

Symptoms: When cucumbers lack zinc and iron, the plants are prone to yellow heads. Some of the top leaves show yellowing and albino between the veins, and some show yellow spots or patches.

Solution: When using base fertilizer, not only should pay attention to the balance between organic fertilizer and chemical fertilizer, but also the balance between large and medium elements and trace elements. It can be relieved by spraying boron calcium and other foliar fertilizers. At the same time, pay attention to applying alginic acid, chitin and other rooting agents to nourish the roots.
