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 planting 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 to solve the lack of these elements in cucumber? 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 stubble, 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 cucumbers lack magnesium, the mesophyll between the veins of the lower leaves of the plant gradually chlorosis, the veins still remain green, forming a clear network of flowers and leaves, and the leaves are hard.

Solution: Apply calcium magnesium phosphate fertilizer, magnesium carbonate and other magnesium-containing fertilizers when applying base 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 lacks boron, the growth point of the plant is necrotic, and the floral development is not complete. The internodes near the growth point are obviously shortened, the leaf margins show yellowing edges, and the leaf margins are yellowing toward the depth, showing the leaf margin broadband xanthosis, and the leaf veins have atrophy.

Solution: Add 1.5 to 2 kg of borax when applying basal 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 appear, foliar sprays of chelated boron can be used to solve the problem.

4. Cucumber lacks zinc and iron

Symptoms: When cucumbers lack zinc and iron, the plants tend to cause 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 rooting agents such as alginic acid and chitin to nourish the roots.
