The latest symptom of element deficiency in cucumber and its prevention and treatment

Cucumber is planted all over our country, whether it is large-scale planting or family planting, it is very popular. When planting cucumbers, we often encounter many problems that affect the growth of cucumbers. One of the reasons is due to the lack of trace elements, lack of trace elements will lead to cucumber deficiency. So what are the symptoms of cucumber deficiency? How to prevent and cure it? Let's take a look at it with the editor.

1. Calcium deficiency

The demand for calcium in the growth of cucumber is still relatively large. If cucumber is deficient in calcium, there will be dwarfing, short internodes and other phenomena. Especially in the top organizing committee, the upper leaves of the plant are very small, and the edges will gradually die. The leaves will gradually form, mushroom-like, and gradually dry up from the outside to the inside. Therefore, when we change the stubble to plant cucumber, we should pay attention to apply the right amount of nitrogen fertilizer. Appropriate amount of calcium nitrate and lime can be added to organic fertilizer. At the same time, it is necessary to control the amount of potassium and nitrogen fertilizer, otherwise it will inhibit the absorption of calcium by the plant. When there is a phenomenon of calcium deficiency, it is necessary to properly spray foliar fertilizer such as calcium chloride to supplement calcium in time.

2. Magnesium deficiency

Magnesium deficiency is also one of the main trace elements of cucumber deficiency. When there is magnesium deficiency in cucumber, the mesophyll in the middle of leaf veins at the lower end of the plant will turn yellow, but the veins will not be affected and chlorosis will occur. So the leaves will gradually form a network of flowers and leaves, touch the leaves can be found that the leaves are hard. Therefore, when we apply base fertilizer, we should pay attention to adding appropriate amount of calcium magnesium phosphate fertilizer, magnesium carbonate and other magnesium-rich fertilizers. Control the amount of nitrogen fertilizer, and spray foliar fertilizer containing magnesium if it is deficient in magnesium. At the same time, we should also pay attention to supplement potash fertilizer and zinc fertilizer to promote the absorption of magnesium.

3. Boron deficiency

If the cucumber plant is lack of boron, then the growth point of the plant will gradually die. The development of floral organ was blocked, and obvious shortening was found in the internodes near the growing point. The edge of the leaf will gradually yellowing, and the vein will gradually atrophy. Therefore, like magnesium deficiency, we should also pay attention to adding appropriate amount of borax when applying potash fertilizer to avoid boron deficiency in cucumbers. At the same time, when applying fertilizer, we should mainly measure the soil and fertilizer to keep the soil water content. When boron deficiency occurs, appropriate amount of chelated boron can be sprayed on plant leaves.

4. Zinc and iron deficiency

In addition to the above three, cucumber plants lack zinc, iron and other elements will also appear deficiency. And lack of zinc and iron, the symptoms are the same, prone to yellow head phenomenon. The veins of the leaves at the top appear yellow and white, and sometimes spots appear. In order to prevent the lack of zinc and iron, we should pay attention to the balance between organic fertilizer and chemical fertilizer when applying base fertilizer. Control the proportion of large, medium and trace elements and properly spray some foliar fertilizers such as boron and calcium. Then pay attention to do a good job of root maintenance to ensure the normal growth of cucumbers.

The above is a brief introduction to the symptoms and prevention of cucumber deficiency. That's all for today's introduction. This article is for reference only. I hope it can help you all.
